Morpholinones as light stabilizers

Description

The invention relates to new 3,3,5,5-tetrasubstituted 2-morpholinones, their use as stabilizers for organic material against deleterious effects of light, oxygen and/or heat, organic material correspondingly stabilized and a process for stabilizing organic material.
Structure and numbering of 2-morpholinone is as shown in the formula: ##STR2##
An important type of stabilizers for organic material are the hindered amine light stabilizers, whose chemical structure is usually derived from 2,2,6,6-tetramethylpiperidine.
The use of some 3,3-disubstituted 2-morpholinones as an additive for fuels or lubricants is described in U.S. Pat. No. 3,371,040.
U.S. Pat. Nos. 4,528,370, 4,914,232 and 5,089,614 disclose as a new class of light stabilizers for organic materials some specific 3,3,5,5-tetrasubstituted 2-morpholinones. Some of these compounds are also described by J. T. Lai in Synthesis (1984), 122.
EP-A-248494 describes the formation of a polybutadiene capped by reaction with 3,3,5,5-tetramethyl-morpholin-2-one.
It has now been found that a modified class of compounds of the 2-morpholinone type is especially well suitable for protecting organic material against harmful effects of light, oxygen and/or heat.

All residues may be straight chain or branched unless otherwise indicated.
An oligocyclic hydrocarbon residue of 6-12 carbon atoms is mainly bicycloalkyl, bicycloalkenyl, tricycloalkyl or tricycloalkenyl of 6-12 carbon atoms.
A substituent halogen is --F, --Cl, --Br or --I; preferably --F or --Cl, especially --Cl.
Alkali metal is mainly Li, Na, K, Rb, Cs, especially Na or K; it is often present as cation forming a salt of a carboxy group.
Open bonds in alkylene or cycloalkylene residues may be attached on different carbon atoms or on the same carbon atom, thus embracing alkylidene or cycloalkylidene. Alkylidene and cycloalkylidene are saturated divalent hydrocarbons having both open bonds localized on the same carbon atom; for instance, C.sub.1 -C.sub.4 alkylidene embraces C.sub.1 alkylidene which is methylene.
Organic residues like X as an organic anchor group are hydrocarbons which may additionally contain hetero atoms as specified. A hydrocarbon alone, i.e. without hetero atoms, consists of carbon and hydrogen; if there is more than one carbon atom present, these can be linked to each other by single, double or triple bonds, open bonds being linked to hydrogen as known in organic chemistry.
Of pronounced value are compounds of the formula F wherein m is 1 and X contains at least 5 carbon or hetero atoms, especially 5 carbon atoms, or wherein m is a number from the range 2-8.
Preferably, X is an m-valent hydrocarbon radical consisting of 1-100 carbon atoms, or is an m-valent organic radical consisting of 1-200 carbon atoms and 1-60 hetero atoms selected from N, O, S, halogen, P, Si, alkali metal, Ca and Zn, and hydrogen atoms, or X is P.
Usually, m is the number of groups of the 2-morpholinone type in compounds of the formula F, and X does not comprise a group of the 2-morpholinone type.
Hetero atoms are non-carbon and non-hydrogen atoms, for instance N, O, S, halogen, P, Si; alkali metal, Ca or Zn can be contained e.g. as carboxylate. Preferred hetero atoms are N, O, S or P, especially N, S and O.
Organic residues or hydrocarbons containing heteroatoms, such as alkyl or alkylene interrupted by hetero groups like oxygen or NH, usually contain these heteroatoms as typical functional groups like oxo, oxa, hydroxy, carboxy, ester, amino, amido, nitro, nitrilo, isocyanato, fluoro, chloro, bromo, phosphate, phosphonate, phosphite, silyl, thio, sulfide, sulfinyl, sulfo, heterocyclyl including pyrrolyl, indyl, carbazolyl, furyl, benzofuryl, thiophenyl, benzothiophenyl, pyridyl, chinolyl, isochinolyl, pyridazinyl, pyrimidinyl, pyrazinyl, triazolyl, benzotriazolyl, triazinyl, pyrazolyl, imidazolyl, thiazolyl, oxazolyl, and corresponding saturated and/or substituted groups like, for example, piperidyl, piperazinyl, morpholinyl etc. They may be interrupted by one or more of these groups; usually there are no linkages of the type O--O, O--N (except nitro, cyanato, isocyanato, nitroso), N--N (except in heterocyclic ring structures), N--P or P--P present, regardless of the order.
Preferably, in organic residues or hydrocarbons containing heteroatoms, for example alkyl or alkylene residues like X, R.sub.5 or R.sub.10, there is not more than one heteroatom attached by a single bond to the same carbon atom. A spacer consisting of one or more heteroatoms such as defined below usually is embedded in a carbon chain or ring or inserted into a carbon-hydrogen bond.
Preferred compounds are those wherein R.sub.5 is C.sub.1 -C.sub.4 alkylene, especially methylene, and R.sub.10 is --CH.sub.2 --CH(R')-- with R' being H or C.sub.1 -C.sub.4 alkyl and Z is O.
Z is preferably a direct bond, --O-- or --NR'.sub.14 --; especially --O-- or --NR'.sub.14 --.
When Z in formula F is a direct bond, X directly bonds to A; when a linking group in formula E is a direct bond, the morpholinone ring directly bonds to Z or, if Z is also a direct bond, to X. In case that both Z and X are direct bonds, 2 moieties of the formula E are directly linked together.
Also preferred are compounds of formula F, wherein G.sub.1 is the linking group --CH.sub.2 --CH(R')-- with R' being H or C.sub.1 -C.sub.4 alkyl and Z is as defined, or G.sub.5 is the linking group C.sub.1 -C.sub.4 alkylene,
Of particular interest are compounds of the formula F, wherein X is an aliphatic or aromatic or mixed aliphatic-aromatic hydrocarbon of valency m, or an aliphatic or aromatic or mixed aliphatic-aromatic hydrocarbon of valency m containing one or more heteroatoms in the form of one or more spacers selected from O, N, N.sub.2, N.sub.3, S, SO, SO.sub.2, SO.sub.3, SO.sub.4, O.dbd.P(O).sub.3, P(O).sub.3, Si, SiO, SiO.sub.2 between carbon and hydrogen or/and between carbon atoms, and/or one or more substituents selected from O, N and halogen; or X is P, PO or a direct bond; and wherein,

Although the novel intermediates of formulae XI, XIV and E' find their use mainly in the preparation of present compounds of the formula F, they are also active as stabilizer and can be used accordingly, alone or in combination with present compound of formula F or a conventional stabilizer.
The novel compounds of present invention, for example those of formula F, especially those of formula I, II or III, can be employed with advantage for stabilizing organic material against the damaging effect of light, oxygen and/or heat. They are notable for high substrate compatibility and good persistence in the substrate.
The materials to be stabilized can, for example, be oils, fats, waxes, cosmetics or biocides.

The catalysts can be used by themselves in the polymerisation or further activators may be used, typically metal alkyls, metal hydrides, metal alkyl halides, metal alkyl oxides or metal alkyloxanes, said metals being elements of groups Ia, IIa and/or IIIa of the Periodic Table. The activators may be modified conveniently with further ester, ether, amine or silyl ether groups.

The invention therefore also provides compositions comprising
A) an organic material which is sensitive to oxidative, thermal and/or actinic degradation, and
B) at least one compound of the formula F, e.g. of the formula I, II and/or III, and provides for the use of compounds of the formula F for stabilizing organic material against oxidative, thermal or actinic degradation.
The invention likewise comprises a method of stabilizing organic material against thermal, oxidative and/or actinic degradation, which comprises adding to this material at least one compound of the formula F.
Of particular interest is the use of compounds of the formula F as stabilizers in synthetic organic polymers, reprographic, especially photographic material, coatings or cosmetic formulations, especially in thermoplastic polymers and corresponding compositions as well as in coating compositions. Thermoplastic polymers of most importance in present compositions are polyolefines and their copolymers, such as listed above under items 1-3, thermoplastic polyolefin (TPO), thermoplastic polyurethan (TPU), thermoplastic rubber (TPR), polycarbonate, such as in item 19 above, and blends, such as in item 28 above. Of utmost importance are polyethylene (PE), polypropylene (PP), polycarbonate (PC) and polycarbonate blends such as PC/ABS blends.
Some of the above compounds of the formula F are especially well suitable for grafting them onto organic polymers having suitable functional groups. These are mainly compounds of the formula F carrying a hydroxy or epoxy group or an ethylenic double bond.
The invention therefore also pertains to a process for grafting a compound of the formula F carrying a hydroxy or epoxy group or an ethylenic double bond onto an onto polymer carrying suitable functional groups.
Compounds of the formula F suitable for grafting and carrying a hydroxy group are preferably compounds of the formula F, wherein m is 1 and X is hydroxyalkyl or epoxyalkyl or carboxyalkyl; or wherein one of G.sub.1, G.sub.3 or G.sub.5 is hydroxyalkyl; or wherein G.sub.1 is epoxyalkyl.
Polymers having suitable functional groups for the reaction with the hydroxy compounds of formula F are mainly organic polymers containing carboxy, anhydride or epoxy groups. Vice versa, polymers containing hydroxy groups are suitable for reactive bonding with present compounds of the formula F, which contain an epoxy or carboxy group.
Compounds of the formula F suitable for grafting and carrying an epoxy group are preferably compounds of the formula F, wherein m is 1 and X or G.sub.1 is C.sub.3 -C.sub.12 epoxyalkyl, especially glycidyl.
Polymers having suitable functional groups for the reaction with these epoxy compounds are mainly organic polymers containing carboxy and/or hydroxy groups.
Compound s of the formula F suitable for grafting and carrying an ethylenic double bond are preferably compounds of the formula F, wherein m is 1 and X contains a C.sub.3 -C.sub.8 alkenyl moiety or G.sub.1 is C.sub.3 -C.sub.8 alkenyl or C.sub.3 -C.sub.8 alkenyloxy. Grafting is preferably effected by exposure to UV light (photografting).
Polymer s having suitable functional groups for the reaction with these double bonds are mainly unsaturated organic polymers containing ethylenic double bonds in the main chain or in side chains.
Difunctional groups of present formula F, for example compounds containing 2 hydroxy groups, also can act as crosslinkers when used together with suitable polymers as described.
Grafting reactions can be carried out in close analogy to methods known in the art, e.g. to methods described in EP-A-526399, pages 6-16, or to methods described in U.S. Pat. No. 5,189,084. Modified polymers thus obtained are highly stable against deleterious effects of light, oxygen and heat. If they contain reactively bonded units of present formula F in a sufficient amount, e.g. in an amount of 0.5 to 50 g, especially 2 to 20 g units of the formula F on 100 g of the final polymer, these modified polymers themselves can be used as stabilizers.
Other materials to be stabilized with the novel compositions are recording materials. By such materials are meant, for example, those described in Research Disclosure 1990, 31429 (pages 474-480), or in GB-A-2319523 or DE-A-1 9750906, page 22, line 15, until page 105, line 32, for photographic reproduction and other reprographic techniques.
Of special importance is the stabilization of non-silver reprographic materials, for example, those for pressure-sensitive copying systems, microcapsule photocopier systems, heat-sensitive copier systems and ink-jet printing.
The novel recording materials feature an unexpectedly high quality, especially in terms of their light stability.
The novel recording materials have a structure which is known per se and which corresponds to the utility. They consist of a base, for example paper or plastic film, on which one or more coatings are applied. Depending on the type of material, these coats contain the suitable components required, in the case of photographic material for example silver halide emulsions, colour couplers, dyes and the like. The material intended especially for ink-jet printing has a customary base on which there is an absorption layer suitable for ink. Uncoated paper can likewise be employed for ink-jet printing; in this case, the paper functions simultaneously as a base and has the absorbent for the ink. Suitable material for ink-jet printing is described, inter alia, in U.S. Pat. No. 5,073,448, the disclosure content of which is regarded as part of the present description.
The recording material can also be transparent, for example in the case of projection films.
The compound or compounds of the formula F can be incorprated into the material even in the course of manufacture; in papermaking, for example, by addition to the pulp. Another method of use is the spraying of the material with an aqueous solution of compound(s) of the formula F, or the addition thereof to the coating.
Coatings for transparent recording materials for projection must not contain any light-scattering particles such as pigments or fillers.
The colour-binding coatings can contain further additives, for example antioxidants, light stabilizers (including UV absorbers or hindered amine light stabilizers which are not included among the novel compounds of formula F), viscosity improvers, brighteners, biocides and/or antistats.
The coating is usually prepared as follows:
The water-soluble components, for example the binder, are dissolved in water and mixed. The solid components, for example fillers and other additives as already described, are dispersed in this aqueous medium. Dispersion is advantageously brought about with the aid of equipment such as ultrasonic devices, turbine agitators, homogenizers, colloid mills, bead mills, sand mills, high-speed stirrers and the like. A particular advantage of the compounds of the formula F is their ease of incorporation into the coating.
As mentioned, the novel recording materials cover a broad field of use. Compounds of the formula F can be employed, for example, in pressure-sensitive copier systems. They can be added to the paper to protect the microencapsulated dye precursors against light, or to the binder of the developer layer for protecting the dyes formed therein.
Photocopier systems with light-sensitive microcapsules which are developed by pressure are described, inter alia, in U.S. Pat. Nos. 4,416,966; 4,483,912; 4,352,200; 4,535,050; 4,536,5463; 4,551,407; 4,562,137 and 4,608,330; and also in EP-A-139479; EP-A-162664; EP-A-164931; EP-A-237024; EP-A-237025 and EP-A-260129. In all these systems the compounds of the formula F can be added to the colour-accepting layer. Alternatively, the compounds of the formula F can be added to the donor layer for protecting the colour formers against light.
The compounds of the formula F can also be employed in recording materials which are based on the principle of photopolymerization, photosoftening or the rupture of microcapsules, or when heat-sensitive or photosensitive diazonium salts, leuco dyes with oxidizing agent or colour lactones with Lewis acids are used.
Heat-sensitive recording material exploits the colour-imparting reaction between a colourless or weakly coloured base dye and an organic or inorganic colour developer, the recorded image being produced by heat-induced contact of the two materials. This type of heat-sensitive recording material is very widespread, not only as the recording medium for faxes, computers, etc., but also in many other fields, for example in label printing.
The heat-sensitive recording material according to the present invention is composed of a base, a heat-sensitive colour-forming recording layer on this base, and, optionally, a protective layer on the heat-sensitive, colour-forming recording layer. The heat-sensitive, colour-forming recording layer contains as its principal constituent a colour-imparting compound and a colour-developing compound, and also a compound of the formula F. If the said protective layer is present, the compound of the formula F can also be incorporated into the protective layer.
Heat-sensitive recording materials are described, for example, in JP-A 8-267 915.
Further fields of use are recording materials for dye diffusion transfer printing, thermal wax transfer printing and dot matrix printing, and for use with electrostatic, electrographic, electrophoretic, magnetographic and laser-electrophotographic printers, recorders or plotters.
Of the materials mentioned, preference is given to recording materials for dye diffusion transfer printing, as are described, for example, in EP-A-507,734.
Compounds of the formula F can also be employed in inks, preferably for ink-jet printing, for example those as described in U.S. Pat. No. 5,098,477, the disclosure content of which is regarded as part of the present description. The invention therefore also provides an ink comprising at least one compound of the formula F as stabilizer. The ink, especially for ink-jet printing, contains preferably water. Inks contain the stabilizer of the formula F usually in a concentration of from 0.01 to 20% by weight, in particular from 0.5 to 10% by weight.
The novel recording materials, for example photographic recording materials, also offer the advantage over materials comprising conventional HALS that the stabilizers of the formula F are required in a comparatively small amount, meaning also that the thickness of the stabilizer-containing layer remains low, a factor which has a positive effect, inter alia, on the imaging properties. Another advantage of the novel stabilizers is their heightened inherent stability under extreme climatic conditions, especially at high humidity and high temperature. The novel photographic material can be a black and white or a colour photographic material; colour photographic material is preferred.
Examples of colour photographic materials are colour negative films, colour reversal films, colour positive films, colour photographic paper, colour reversal photographic paper, colour-sensitive materials for the dye diffusion transfer process or the silver dye bleach process. Details of the photographic material to be stabilized according to the invention and components which can be employed in the novel material are given, inter alia, in GB-A-2319523, DE-A-19750906, page 23, line 20, until page 105, line 32, and in U.S. Pat. No. 5,538,840, column 25, line 60, to column 106, line 31; these parts of U.S. Pat. No. 5,538,840 are incorporated herein by way of reference.
The compounds of the invention are also valuable light stabilizers in cosmetic, pharmaceutical or veterinary formulations. The substrate to be protected in these applications may be the formulation itself or components thereof, or human or animal skin or hair. The compounds of the invention may be used in dissolved or micronized state. The invention therefore also pertains to a cosmetic formulation containing at least one compound of the formula F and cosmetically acceptable carriers or auxiliary agents. A more detained description of the cosmetic formulations which can be stabilized according to the invention can be found in GB-A-2319523.
The organic polymeric materials to be protected are preferably natural, semisynthetic or, preferably, synthetic organic materials. Particular preference is given to synthetic organic polymers or mixtures of such polymers, especially thermoplastic polymers such as polyolefins, especially polyethylene and polypropylene (PP), and coating compositions.
In general the compounds of the formula F are added to the material to be stabilized in amounts of from 0.1 to 10%, preferably from 0.01 to 5%, in particular from 0.01 to 2% (based on the material to be stabilized). Particular preference is given to the use of the novel compounds in amounts of from 0.05 to 1.5%, especially from 0.1 to 0.5%.
Incorporation into the materials can be effected, for example, by mixing in or applying the compounds of the formula F and, if desired, further additives by the methods which are customary in the art. Where polymers are involved, especially synthetic polymers, incorporation can take place prior to or during the shaping operation, or by applying the dissolved or dispersed compound to the polymer, with or without subsequent evaporation of the solvent. In the case of elastomers, these can also be stabilized as latices. A further possibility for incorporating the compounds of the formula F into polymers is to add them before, during or directly after the polymerization of the corresponding monomers or prior to crosslinking. In this context the compound of the formula F can be added as it is or else in encapsulated form (for example in waxes, oils or polymers). In the case of addition prior to or during the polymerization, the compounds of the formula F can also act as a regulator of the chain length of the polymers (chain terminator).
The compounds of the formula F can also be added in the form of a masterbatch containing said compound in a concentration, for example, of from 2.5 to 25% by weight to the polymers that are to be stabilized.
The compounds of the formula F can judiciously be incorporated by the following methods:
as emulsion or dispersion (e.g. to latices or emulsion polymers),
as a dry mixture during the mixing in of additional components or polymer mixtures,
by direct introduction into the processing apparatus (e.g. extruders, internal mixers, etc),
as solution or melt.
Novel polymer compositions can be employed in various forms and/or processed to give various products, for example as (to give) films, fibres, tapes, moulding compositions, profiles, or as binders for coating materials, adhesives or putties.
In addition to the compounds of the formula F the novel compositions may as additional component C comprise one or more conventional additives such as, for example, those indicated below.

Examples for a benzotriazole of formula K, L, M or N are listed above under item 2.1; examples for a 2-hydroxyphenyltriazine of formulae P and/or Q are listed above under item 2.8.
Likewise of particular interest is the use of the novel mixtures comprising compounds of the formula F as stabilizers for coatings, for example for paints. The invention therefore also relates to those compositions whose component (A) is a film-forming binder for coatings.
The novel coating composition preferably comprises 0.01-10 parts by weight of (B), in particular 0.05-10 parts by weight of (B), especially 0.1-5 parts by weight of (B), per 100 parts by weight of solid binder (A).
Multilayer systems are possible here as well, where the concentration of the novel stabilizer (component (B)) in the outer layer can be relatively high, for example from 1 to 15 parts by weight of (B), in particular 3-10 parts by weight of (B), per 100 parts by weight of solid binder (A).
The use of the novel stabilizer in coatings is accompanied by the additional advantage that it prevents delamination, i.e. the flaking-off of the coating from the substrate. This advantage is particularly important in the case of metallic substrates, including multilayer systems on metallic substrates.
The binder (component (A)) can in principle be any binder which is customary in industry, for example those described in Ullmann's Encyclopedia of Industrial Chemistry, 5th Edition, Vol. A18, pp. 368-426, VCH, Weinheim 1991. In general, it is a film-forming binder based on a thermoplastic or thermosetting resin, predominantly on a thermosetting resin. Examples thereof are alkyd, acrylic, polyester, phenolic, melamine, epoxy and polyurethane resins and mixtures thereof.
Component (A) can be a cold-curable or hot-curable binder; the addition of a curing catalyst may be advantageous. Suitable catalysts which accelerate curing of the binder are described, for example, in Ullmann's Encyclopedia of Industrial Chemistry, Vol. A18, p.469, VCH Verlagsgesellschaft, Weinheim 1991.
Preference is given to coating compositions in which component (A) is a binder comprising a functional acrylate resin and a crosslinking agent.
Examples of coating compositions containing specific binders are:
1. paints based on cold- or hot-crosslinkable alkyd, acrylate, polyester, epoxy or melamine resins or mixtures of such resins, if desired with addition of a curing catalyst;
2. two-component polyurethane paints based on hydroxyl-containing acrylate, polyester or polyether resins and aliphatic or aromatic isocyanates, isocyanurates or polyisocyanates;
3. one-component polyurethane paints based on blocked isocyanates, isocyanurates or polyisocyanates which are deblocked during baking, if desired with addition of a melamine resin;
4. one-component polyurethane paints based on a Trisalkoxycarbonyltriazine crosslinker and a hydroxyl group containing resin such as acrylate, polyester or polyether resins;
5. one-component polyurethane paints based on aliphatic or aromatic urethaneacrylates or polyurethaneacrylates having free amino groups within the urethane strukture and melamine resins or polyether resins, if necessary with curing catalyst;
6. two-component paints based on (poly)ketimines and aliphatic or aromatic isocyanates, isocyanurates or polyisocyanates;
7. two-component paints based on (poly)ketimines and an unsaturated acrylate resin or a polyacetoacetate resin or a methacrylamidoglycolate methyl ester;
8. two-component paints based on carboxyl- or amino-containing polyacrylates and polyepoxides;
9. two-component paints based on acrylate resins containing anhydride groups and on a polyhydroxy or polyamino component;
10. two-component paints based on acrylate-containing anhydrides and polyepoxides;
11. two-component paints based on (poly)oxazolines and acrylate resins containing anhydride groups, or unsaturated acrylate resins, or aliphatic or aromatic isocyanates, isocyanurates or polyisocyanates;
12. two-component paints based on unsaturated polyacrylates and polymalonates;
13. thermoplastic polyacrylate paints based on thermoplastic acrylate resins or externally crosslinking acrylate resins in combination with etherified melamine resins;
14. paint systems based on siloxane-modified or fluorine-modified acrylate resins.
In addition to components (A) and (B), the coating composition according to the invention preferably comprises as component (C) a light stabilizer of the sterically hindered amine type, the 2-(2-hydroxyphenyl)-1,3,5-triazine and/or 2-hydroxyphenyl-2H-benzotriazole type, for example as mentioned in the above list in sections 2.1, 2.6 and 2.8. Further examples for light stabilizers of the 2-(2-hydroxyphenyl)-1,3,5-triazine type advantageously to be added can be found e.g. in the publications U.S. Pat. No. 4,619,956, EP-A-434608, U.S. Pat. No. 5,198,498, U.S. Pat. No. 5,322,868, U.S. Pat. No. 5,369,140, U.S. Pat. No. 5,298,067, WO-94/18278, EP-A-704437, GB-A-2297091, WO-96/28431. Of special technical interest is the addition of the 2-(2-hydroxyphenyl)-1,3,5-triazines and/or 2-hydroxyphenyl-2H-benzotriazoles, especially the 2-(2-hydroxyphenyl)-1,3,5-triazines.
To achieve maximum light stability, it is of particular interest to add sterically hindered amines as set out in the abovementioned list under 2.6. The invention therefore also relates to a coating composition which in addition to components (A) and (B) comprises as component (C) a light stabilizer of the sterically hindered amine type.
This stabilizer is preferably a 2,2,6,6-tetraalkylpiperidine derivative containing at least one group of the formula ##STR65## in which G is hydrogen or methyl, especially hydrogen.
Component (C) is preferably used in an amount of 0.05-5 parts by weight per 100 parts by weight of the solid binder.
Examples of tetraalkylpiperidine derivatives which can be used as component (C) are given in EP-A-356 677, pages 3-17, sections a) to f). These sections of this EP-A are regarded as part of the present description. It is particular expedient to employ the following tetraalkylpiperidine derivatives:
bis(2,2,6,6-tetramethylpiperid-4-yl)succinate,
bis(2,2,6,6-tetramethylpiperid-4-yl)sebacate,
bis(1,2,2,6,6-pentamethylpiperid-4-yl)sebacate,
di(1,2,2,6,6-pentamethylpiperid-4-yl)butyl-(3,5-di-tert-butyl-4-hydroxybenzyl)malonate,
bis(1-octyloxy-2,2,6,6-tetramethylpiperid-4-yl)sebacate,
tetra(2,2,6,6-tetramethylpiperid-4-yl)butane-1,2,3,4-tetracarboxylate,
tetra(1,2,2,6,6-pentamethylpiperid-4-yl)butane-1,2,3,4-tetracarboxylate,
2,2,4,4-tetramethyl-7-oxa-3,20-diaza-21-oxo-dispiro[5.1.11.2]heneicosane,
8-acetyl-3-dodecyl-1,3,8-triaza-7,7,9,9-tetramethylspiro[4.5]decane-2,4-dione,
1,1-bis-(1,2,2,6,6-pentamethylpiperidine-4-yl-oxycarbonyl)-2-(4-methoxyphenyl)-ethene,
or a compound of the formulae ##STR66## in which m is 5-50.
Apart from components (A), (B) and, if used, (C), the coating composition can also comprise further components, examples being solvents, pigments, dyes, plasticizers, stabilizers, thixotropic agents, drying catalysts and/or levelling agents. Examples of possible components are those described in Ullmann's Encyclopedia of Industrial Chemistry, 5th Edition, Vol. A18, pp. 429-471, VCH, Weinheim 1991.
Possible drying catalysts or curing catalysts are, for example, organometallic compounds, amines, amino-containing resins and/or phosphines. Examples of organometallic compounds are metal carboxylates, especially those of the metals Pb, Mn, Co, Zn, Zr or Cu, or metal chelates, especially those of the metals Al, Ti or Zr, or organometallic compounds such as organotin compounds, for example.
Examples of metal carboxylates are the stearates of Pb, Mn or Zn, the octoates of Co, Zn or Cu, the naphthenates of Mn and Co or the corresponding linoleates, resinates or tallates.
Examples of metal chelates are the aluminium, titanium or zirconium chelates of acetylacetone, ethyl acetylacetate, salicylaldehyde, salicylaldoxime, o-hydroxyacetophenone or ethyl trifluoroacetylacetate, and the alkoxides of these metals.
Examples of organotin compounds are dibutyltin oxide, dibutyltin dilaurate or dibutyltin dioctoate.
Examples of amines are, in particular, tertiary amines, for example tributylamine, triethanolamine, N-methyldiethanolamine, N-dimethylethanolamine, N-ethylmorpholine, N-methylmorpholine or diazabicyclooctane (triethylenediamine) and salts thereof. Further examples are quaternary ammonium salts, for example trimethylbenzylammonium chloride.
Amino-containing resins are simultaneously binder and curing catalyst. Examples thereof are amino-containing acrylate copolymers.
The curing catalyst used can also be a phosphine, for example triphenylphosphine.
The novel coating compositions can also be radiation-curable coating compositions. In this case, the binder essentially comprises monomeric or oligomeric compounds containing ethylenically unsaturated bonds, which after application are cured by actinic radiation, i.e. converted into a crosslinked, high molecular weight form. Where the system is UV-curing, it generally contains a photoinitiator as well. Corresponding systems are described in the abovementioned publication Ullmann's Encyclopedia of Industrial Chemistry, 5th Edition, Vol. A18, pages 451-453. In radiation-curable coating compositions, the novel stabilizers can also be employed without the addition of sterically hindered amines.
The coating compositions according to the invention can be applied to any desired substrates, for example to metal, wood, plastic or ceramic materials. They are preferably used as topcoat in the finishing of automobiles. If the topcoat comprises two layers, of which the lower layer is pigmented and the upper layer is not pigmented, the novel coating composition can be used for either the upper or the lower layer or for both layers, but preferably for the upper layer.
The novel coating compositions can be applied to the substrates by the customary methods, for example by brushing, spraying, pouring, dipping or electrophoresis; see also Ullmann's Encyclopedia of Industrial Chemistry, 5th Edition, Vol. A18, pp. 491-500.
Depending on the binder system, the coatings can be cured at room temperature or by heating. The coatings are preferably cured at 50-150.degree. C., and in the case of powder coatings or coil coatings even at higher temperatures.
The coatings obtained in accordance with the invention have excellent resistance to the damaging effects of light, oxygen and heat; particular mention should be made of the good light stability and weathering resistance of the coatings thus obtained, for example paints.
The invention therefore also relates to a coating, in particular a paint, which has been stabilized against the damaging effects of light, oxygen and heat by a content of the compound of the formula F according to the invention. The paint is preferably a topcoat for automobiles. The invention furthermore relates to a process for stabilizing a coating based on organic polymers against damage by light, oxygen and/or heat, which comprises mixing with the coating composition a mixture comprising a compound of the formula F, and to the use of mixtures comprising a compound of the formula F in coating compositions as stabilizers against damage by light, oxygen and/or heat.
The coating compositions can comprise an organic solvent or solvent mixture in which the binder is soluble. The coating composition can otherwise be an aqueous solution or dispersion. The vehicle can also be a mixture of organic solvent and water. The coating composition may be a high-solids paint or can be solvent-free (e.g. a powder coating material). Powder coatings are, for example, those described in Ullmann's Encyclopedia of Industrial Chemistry, 5th Ed., A18, pages 438-444. The additive of present invention can be used therein e.g. as described e.g. in EP-A-856563, especially page 22, line 21, until page 26, line 29, and literature cited in this reference.The powder coating material may also have the form of a powder-slurry (dispersion of the powder preferably in water).
Examples of resins for powder coatings are:
1. Carboxy- or hydroxy-functionalised polyester resins, based on monomers such as terephthalic acid, isophthalic acid, neopentyl glycol, 2-methyl-1,3-propandiol, tris-1,1,1-(hydroxymethyl)propane etc.
2. Epoxy resins based on bisphenols, such as bisphenol A or Novolac.RTM. epoxy resins for thermal or uv-cure with cationic photoinitiators.
3. Hydroxy-, carboxy- or glycidyl-functionalised acrylate polymers and copolymers. Suitable comonomers include styrene, alkyl methacrylates, acrylamide, acrylonitrile etc.
4. Unsaturated polyester resins for uv-cureable powder coatings, typically used in conjunction with multifuntional vinyl ethers or acrylate esters.
Powder coating based on resins with carboxy functionality are typically used together with crosslinking agents of the following classes:
1) polyfunctional epoxy compounds, such as epoxy resins, triglycidylisocyanurate, epoxidised unsaturated fatty acid esters (such as Uranox.RTM. resins from DSM), and esters and ethers of glycidol (such as Araldit.RTM. PT910 from Ciba Specialty Chemicals).
2) .beta.-hydroxyalkylamides, such as Primid.RTM. types XL552 and QM1260 from Ems Chemie.
3) derivatives of melamine, benzoguanimine and glycoluril, such as Powderlink.RTM. 1174 from American Cyanamid.
Crosslinking agents for resins of hydroxy functionality include anhydrides and especially blocked diisocyanates and uretdiones, etc.
Powder coatings based on resins with epoxy functionality are typically used together with crosslinking agents such as diacids (such as 1,12-dodecanedioic acid), carboxy-functional polyesters, carboxy-functional copolymers of acrylates and methacrylates, anhydrides (such as the anhydride prepared from 1,12-dodecanedioic acid).
Other additives that can be used together with the compounds of the invention in powder coatings include: degassing agents, flow promoters, tribocharging additives cure catalysts, sensitisers, cationic and free-radical photoinitiators, as well as typical liquid paint additives.
A particular advantage of the compounds of the invention is their low basicity, as basic compounds often catalyse the crosslinking reactions of powder coatings to cause poor flow and degassing, and reduced storage stability. This is particularly useful in formulations of high reactivity, such as the glycidylmethacrylate-functionalised acrylics. Here, the combination of the compounds of the invention together with uv-absorbers, especially of the hydroxyphenyltriazine class, can be used to improve the weatherability without causing catalysis. In other binder systems and with other classes of uv-absorbers, such as those previously mentioned to be of particular use in automotive paints, synergistic effects on the weatherability are also found.
In powder coatings the compounds of the invention can also be used to improve the oxidative stability and reduce yellowing on curing and overbaking. Here not only is the low basicity advantageous, but also the ability of the hindered morpholinones to withstand and prevent yellowing caused by oxides of nitrogen in gas-fired ovens. Use together particularly with phosphite and phosphonite costabilisers, as disclosed in EP-A-816442, and dialkylesters of dithiopropionic acid is particularly beneficial. The compounds of the invention can, where appropriate also be used to stabilise polyester during manufacture as well as at all stages of its subsequent use.
The pigments can be inorganic, organic or metallic pigments. The novel coating compositions preferably contain no pigments and are used as a clearcoat.
Likewise preferred is the use of the coating composition as a topcoat for applications in the automobile industry, especially as a pigmented or unpigmented topcoat of the paint finish. Its use for underlying coats, however, is also possible.

Whenever room temperature is mentioned, this denotes a temperature in the range 20-25.degree. C. In the examples, the following abbreviations are used:
