Photopolymerizable composition

FIELD OF THE INVENTION
The present invention relates to a photopolymerizable composition, more specifically, it relates to a photopolymerizable composition comprising a photopolymerization initiation system using a novel composition capable of exhibiting excellent light sensitivity to visible light.
BACKGROUND OF THE INVENTION
The photopolymerizable composition is a material which undergoes changes in the physical properties of the composition upon polymerization induced by light irradiation and is widely used in the fields of printing, printed circuit, fine processing such as ultra LSI, painting, ink, hologram recording and three dimensional molding, thus the application of the composition is more and more expanding. The photopolymerizable composition fundamentally comprises an addition-polymerizable, ethylenically unsaturated compound and a photopolymerization initiator. Since this kind of composition undergoes polymerization upon light irradiation and thereby is cured and insolubilized, a photosensitive composition is prepared by adding a binder resin having a film-forming ability and a heat polymerization inhibitor, if desired, to the photopolymerizable composition to form an appropriate coating and subjected to light irradiation through a desired negative image and only the non-irradiated area is removed by a proper solvent (hereinafter referred simply as "development") to form an objective cured image. Such an image formation method is well known very useful in preparing a printing plate.
The photopolymerization initiator used in the polymerizable composition is conventionally benzyl, benzoin ether, Michler's ketone, anthraquinone, acridine, phenazine or benzophenone. However, the composition comprising such a photopolymerization initiator is low in the sensitization rate and extremely poor in the photopolymerization ability to visible light at 400 nm or more as compared with the photopolymerization ability to the light in an ultraviolet wavelength region of less than 400 nm. Accordingly, the photopolymerizable composition comprising a conventional photopolymerization initiator is strictly limited on the application range thereof.
A photosensitive composition able to be highly cured by a small amount of light irradiation has been long demanded. Such a photosensitive composition is useful as a photosensitive material suitable, for example, for the projection exposure of non-contact type. Further, in recent years, the image information technique using a visible laser has come into a practical use and accordingly, a photosensitive composition having a high photopolymerization ability to visible light has been keenly demanded. The visible laser light which is very expected to be use in such a method is an Ar.sup.+ laser light having a wavelength at 488 nm, YAG--SHG laser light having a wavelength at 532 nm, or He--Ne laser light having a wavelength at 543 nm.
With respect to the photopolymerizable composition comprising a photopolymerization initiation system sensitive to visible light, several proposals have been offered. For example, U.S. Pat. No. 2,850,445 has reported that certain kinds of photosensitive dyes such as Rose Bengale, Eosine and erythrosine exhibit effective sensitivity to visible light. Also, in improved techniques, a composite initiation system of a dye and an amine (see, JP-B-44-20189 (the term "JP-B" as used herein means an "examined Japanese patent publication")), a system of a hexaarylbiimidazole, a radical generating agent and a dye (see JP-B-45-37377), a system of hexaarylbiimidazole and p-dialkylaminobenzylidene ketone (see, JP-B-47-2528 and JP-A-54-155292 (the term "JP-A" as used herein means an "unexamined published Japanese patent application")), a system of a 3-ketocoumarin compound and an active halogen compound (JP-A-58-15503) and a system of a substituted triazine and a merocyanine dye (see JP-A-54-15102) have been proposed. These techniques are effective to visible light but in practical viewpoint, the sensitivity achieved is still insufficient. JP-A-2-244050 proposes a system comprising a dye having a 4-thiazolidinone skeleton and a radical generating agent as a highly sensitive initiation system. This system is highly sensitive, however, the maximum photosensitivity is in the wavelength region of less than 500 nm and thus the photosensitivity is not sufficient to light at 500 mm or more.
SUMMARY OF THE INVENTION
An object of the present invention is to provide a highly-sensitive photopolymerizable composition, more specifically, a photopolymerizable composition comprising a photopolymerization initiator capable of increasing the photopolymerization rate of a photopolymerization composition containing an addition-polymerizable, ethylenically unsaturated compound.
Another object of the present invention is to provide a photopolymerizable composition containing a photopolymerization initiator having high sensitivity to visible light at 400 nm or more, particularly to light at around 488 nm corresponding to the outputs of an Ar.sup.+ laser or at 500 nm or longer wavelength corresponding to the outputs of a YAG--SHG laser and a He--Ne laser, respectively.
Still another object of the present invention is to provide a photopolymerizable composition capable of providing a photosensitive material having excellent storage stability.
As a result of intensive investigations to achieve the above-described objects, the present inventors have found that a photopolymerizable composition containing a specific photopolymerization initiation system shows a very high photopolymerization rate and high sensitivity even to visible light at 400 nm or more, particularly at 500 nm or more and the present invention has been accomplished based on this finding.

When the above-described co-sensitizer is used, it is preferably used in an amount of from 0.01 to 50 parts by weight, more preferably from 0.02 to 20 parts by weight and most preferably from 0.05 to 10 parts by weight, per 1 part by weight of the compound as component (ii).
The photopolymerizable composition of the present invention preferably contains a linear organic high molecular polymer as a binder. Any linear organic high molecular polymer may be used as long as the linear organic high molecular polymer has compatibility with the photopolymerizable, ethylenically unsaturated compound. A water- or alkalescent water-soluble or swellable linear organic high molecular polymer capable of water development or alkalescent water development is preferably selected. The linear organic high molecular polymer is used not only as the film forming agent of the composition but also as a developer appropriately selected depending on the use of water, alkalescent water or an organic solvent. For example, when a water-soluble organic high molecular polymer is used, water development can be carried out. This kind of a linear organic high molecular polymer includes an addition polymer having a carboxylic acid group on the side chain and examples thereof include a methacrylic acid copolymer, an acrylic acid copolymer, an itaconic acid copolymer, a crotonic acid copolymer, a maleic acid copolymer and a partially esterified maleic acid copolymer described in JP-A-59-44615, JP-B-54-34327, JP-B-58-12577, JP-B-54-25957, JP-A-54-92723, JP-A-59-53836 and JP-A-59-71048. Further, an acidic cellulose derivative having a carboxylic acid group on the side chain may be used. An addition product of a cyclic acid anhydride to the addition polymer having a hydroxyl group may also be useful. Among these, a [benzyl (meth)acrylate/ (meth)acrylic acid/other addition polymerizable vinyl monomer, if desired] copolymer and an [allyl (meth)acrylate/(meth)acrylic acid/other addition polymerizable vinyl monomer, if desired] copolymer are preferred. In addition, polyvinyl pyrrolidone and polyethylene oxide are useful as a water-soluble linear organic polymer. Further, an alcohol-soluble polyamide and a polyether of 2,2-bis(4-hydroxyphenyl)propane with epichlorohydrin are also useful so as to increase the strength of the cured film. The above-described linear organic high molecular polymer can be mixed into the entire composition in a freely selected amount. However, if the mixing amount exceeds 90 wt %, disadvantageous results may be caused in view of the strength of an image formed and the like. The mixing amount is preferably from 30 to 85%. The ratio of the photopolymerizable, ethylenically unsaturated compound to the linear organic high molecular polymer is preferably from 1/9 to 7/3 (by weight), more preferably from 3/7 to 5/5.
In addition to the above-described fundamental components, a slight amount of a heat polymerization inhibitor is preferably added in the present invention so as to prevent unnecessary heat polymerization of the polymerizable, ethylenically unsaturated compound during the production or storage of the photosensitive composition. Suitable examples of the heat polymerization inhibitor include hydroquinone, p-methoxyphenol, di-t-butyl-p-cresol, pyrogallol, t-butylcatechol, benzoquinone, 4,4'-thiobis(3-methyl-6-t-butylphenol), 2,2'-methylenebis(4-methyl-6-t-butylphenol), N-nitrosophenylhydroxylamine primary cerium salt and N-nitrosophenylhydroxylamine aluminum salt. The addition amount of the heat polymerization inhibitor is preferably from about 0.01 to about 5% based on the weight of the entire composition. Also, if desired, a higher fatty acid derivative such as a behenic acid and a behenic acid amide may be added to disperse unevenly on the surface of the photosensitive layer during the drying process after coating so as to prevent the polymerization inhibition due to oxygen. The addition amount of the higher fatty acid derivative is preferably from about 0.5 to about 10% of the entire composition.
In the present invention, a dye or a pigment may be added for the purpose of coloring the photosensitive layer. The addition amount of the dye or the pigment is from 0.01 to 20%, preferably from 0.5 to 10% by weight of the entire composition. A pigment is preferred more than a dye.

The aliphatic ring formed by Q is preferably an aliphatic ring having from 5 to 30 carbon atoms as a combination of 5- or 6-membered rings (e.g., cyclohexane ring, norbornenyl ring, dicyclopentadiene ring). The aliphatic ring includes bicyclic or tricyclic hydrocarbon having a bridge head carbon atom. The carbon-carbon double bond present in the aliphatic ring is preferably one.
The photopolymerizable composition of the present invention may contain an inorganic filler or other known additives for improving the physical properties of the cured film.
Further, a surface active agent is preferably added so as to improve the surface state on coating. As the surface active agent, fluorine-based surface active agents are preferred.
The photopolymerizable composition of the present invention is dissolved in various organic solvents and then coated on a support. Examples of the solvent include acetone, methyl ethyl ketone, cyclohexane, ethyl acetate, ethylene dichloride, tetrahydrofuran, toluene, ethylene glycol monomethyl ether, ethylene glycol monoethyl ether, ethylene glycol dimethyl ether, propylene glycol monomethyl ether, propylene glycol monoethyl ether, acetylacetone, cyclohexanone, diacetone alcohol, ethylene glycol monomethyl ether acetate, ethylene glycol ethyl ether acetate, ethylene glycol monoisopropyl ether, ethylene glycol monobutyl ether acetate, 3-methoxypropanol, methoxymethoxyethanol, diethylene glycol monomethyl ether, diethylene glycol monoethyl ether, diethylene glycol dimethyl ether, diethylene glycol diethyl ether, propylene glycol monomethyl ether acetate, propylene glycol monoethyl ether acetate, 3-methoxypropyl acetate, N,N-dimethylformamide, dimethyl sulfoxide, .gamma.-butyrolactone, methyl lactate and ethyl lactate. These solvents may be used individually or in combination. The solid concentration in the coating solution is suitably from 2 to 50 wt %. The coverage thereof is in terms of the weight after drying preferably from about 0.1 to about 10 g/m.sup.2, more preferably from 0.5 to 5 g/m.sup.2.
As the above-described support, a dimensionally stable, plate-like material is used. Examples of the dimensionally stable, plate-like material include paper, paper laminated with plastics (e.g., polyethylene, polypropylene, polystyrene), sheet of a metal such as aluminum (including aluminum alloy), zinc or copper, a plastic film such as cellulose diacetate, cellulose triacetate, cellulose propionate, cellulose lactate, cellulose acetate lactate, cellulose nitrate, polyethylene terephthalate, polyethylene, polystyrene, polypropylene, polycarbonate or polyvinyl acetal, and paper or plastic film laminated with or having evaporated thereon the above-described metal. Among these supports, an aluminum plate is particularly preferred because it is dimensionally stable to an extreme extent and in addition, cheap. Also, a composite sheet obtained by bonding an aluminum sheet on a polyethylene terephthalate film described in JP-B-48-18327 may be preferably used.
A support having a metal, particularly an aluminum surface is preferably subjected to surface treatment such as graining treatment, dipping treatment in an aqueous solution of sodium silicate, potassium fluorozirconate or phosphate, or anodic oxidation treatment.
The graining treatment is preferably conducted by brush graining or electrolysis graining. In the case of electrolysis graining, the electrolyte is preferably an aqueous solution of nitric acid or hydrochloric acid, more preferably an aqueous solution of nitric acid.
Further, an aluminum plate subjected to graining and then to dipping treatment in an aqueous solution of sodium silicate may be preferably used. An aluminum plate subjected to anodic oxidation treatment and then to dipping treatment in an aqueous solution of alkali metal silicate described in JP-B-47-5125 may be also suitably used.
The anodic oxidation treatment is carried out by applying current to the aluminum plate as an anode in an electrolyte, for example, in an aqueous or non-aqueous solution of an inorganic acid such as phosphoric acid, chromic acid, sulfuric acid or boric acid or of an organic acid such as oxalic acid or sulfamic acid, which solutions may be used individually or in combination of two or more thereof.
The silicate electrodeposition described in U.S. Pat. No. 3,658,662 is also effective.
Further, the surface treatment comprising a combination of electrolysis graining with the above-described anodic oxidation treatment and sodium silicate treatment disclosed in JP-B-46-27481, JP-A-52-58602 and JP-A-52-30503 is also useful. In this case, the sodium silicate treatment may be omitted.
Furthermore, a support is also suitably subjected to mechanical graining, chemical etching, electrolysis graining, anodic oxidation treatment and sodium silicate treatment successively as disclosed in JP-A-56-28893.
Still further, a support is suitably subjected, after the above-described treatments, to undercoating by a water-soluble resin such as a polymer or copolymer having a polyvinyl phosphonic acid or a sulfonic acid on the side chain or a polyacrylic acid, a water-soluble metal salt (e.g., zinc borate), a yellow dye or an amine salt.
The above-described treatment to achieve hydrophilicity is effected not only to render the support surface hydrophilic but also to prevent harmful reaction of the photopolymerizable composition to be coated thereon and to improve the adhesion to the photosensitive layer.
Further, the back surface of the support is preferably subjected to backcoating described in JP-A-5-2271 and JP-A-6-35174 so as to prevent the elution of aluminum into the developer.
In order to prevent polymerization inhibition action of the oxygen in air, a protective layer comprising a polymer having a low oxygen permeation rate, such as polyvinyl alcohol, in particular, polyvinyl alcohol having a saponification degree of 95% or more, or an acidic cellulose, may be provided on the photopolymerizable composition layer on the support. The coating method of the protective layer is described in detail, for example, in U.S. Pat. No. 3,458,311 and JP-A-55-49729. The coating amount thereof is preferably from 0.1 to 5.0 g, more preferably from 0.5 to 3 g .
The photopolymerizable composition of the present invention can be used for usual photopolymerization. Further, the composition can be used in various fields, for example, as a photoresist in producing a printing plate or a printed board. In particular, since the photopolymerizable composition of the present invention has such properties as high sensitivity and wide spectral sensitivity extending even to a visible light region, it can provide good effects when it is applied to a photosensitive material for a visible light laser such as an Ar.sup.+ laser or a YAG-SHG laser.
Further, the photopolymerizable composition of the present invention is highly sensitive and has sensitivity to visible light and therefore, it can be advantageously used particularly for an image formation system using a microcapsule.
The application to the image formation system using a microcapsule is described, for example, in JP-A-57-197538, JP-A-61-130945, JP-A-58-88739, JP-A-58-88740 and European Patent Application No. 223,587A1. This image formation method comprises coating a microcapsule containing, for example, a photopolymerization initiator composition consisting of an ethylenic vinyl compound and a photopolymerization initiator and a dye precursor on a support, imagewise exposing the resulting photosensitive sheet to cure microcapsules on the exposed area, superposing a developer sheet thereon and applying pressure throughout the sheet to rapture the microcapsules on the unexposed area, whereby a dye image-forming material (e.g., a dye precursor) is transferred to an image-receiving element (e.g., developer layer) to form colors thereon.
The photosensitive material using the photopolymerizable composition of the present invention may be heated after the imagewise exposure. The heating temperature is preferably from 60.degree. to 160.degree. C., more preferably from 80.degree. to 130.degree. C. The heating time is preferably from 1 second to 5 minutes.
The unexposed area of the photosensitive layer is removed by a developer to obtain an image. In using the photopolymerizable composition for producing a lithographic printing plate, the developer described in JP-B-57-7427 is preferred and an aqueous solution of an inorganic alkali agent such as sodium silicate, potassium silicate, sodium hydroxide, potassium hydroxide, lithium hydroxide, sodium tertiary phosphate, sodium secondary phosphate, ammonium tertiary phosphate, ammonium secondary phosphate, sodium metasilicate, sodium bicarbonate or aqueous ammonia or of an organic alkali agent such as monoethanolamine or diethanolamine is suitably used. The alkali agent is added to give a concentration of from 0 1 to 10 wt % preferably from 0.5 to 5 wt %.
The above-described alkaline aqueous solution may contain, if desired, a surface active agent or an organic solvent such as benzyl alcohol, 2-phenoxyethanol or 2-butoxyethanol, in a small amount. Examples thereof include those described in U.S. Pat. Nos. 3,375,171 and 3,615,480. Further, the developers described in JP-A-50-26601, JP-A-58-54341, JP-B-56-39464 and JP-B-56-42860 are also excellent.
However, the use of the organic solvent involves a hygienic problem such as toxicity and odor at the operation site, a safety problem such as firing, a problem in view of operationability such as generation of bubbles, or a problem such as environmental pollution due to the waste water and accordingly, the developer preferably contains substantially no organic solvent. The aqueous alkali developer substantially free of an organic solvent includes the developer composition described, for example, in JP-A-59-84241 and JP-A-57-192952.
A commercially available developer which can be suitably used is a solution obtained by diluting DP-4 (produced by Fuji Photo Film Co., Ltd.) with water to from 1/6 to 1/30.
The photosensitive lithographic printing plate using a photopolymerizable composition of the present invention may be subjected to such treatment after development as described in JP-A-54-8002, JP-A-55-115045 and JP-A-59-58431, more specifically, desensitizing treatment through or without water washing, treatment with an aqueous solution containing an acid or desensitizing treatment after treatment with an aqueous solution containing an acid. In the development process of this kind of photosensitive lithographic printing plate, the aqueous alkali solution is consumed according to the processed amount to cause reduction in the alkali concentration or the alkali concentration is reduced due to air in a long-time operation in an automatic developing machine and as a result, the processing capacity is lowered. In this case, the processing capacity can be recovered by the replenisher and the replenishing method described in JP-A-54-62004, JP-A-55-22759, JP-A-55-115039, JP-A-56-12645, JP-A-58-95349, JP-A-64-21451, JP-A-1-180548 and JP-A-2-3065.
The above-described print-making process is preferably carried out in an automatic developing machine described in JP-A-2-7054 and JP-A-2-32357. As the desensitizing gum to be coated, if desired, at the final step of the print-making process, those described in JP-B-62-16834, JP-B-62-25118, JP-B-63-52600, JP-A-62-7595, JP-A-62-11693 and JP-A-62-83194 are preferably used.
After the development, the printing plate may be subjected to burning heat treatment or post exposure to improve the impression capacity at printing.
The photopolymerizable composition of the present invention exhibits high sensitivity to active light over a wide region from ultraviolet light to visible light. Accordingly, an ultrahigh-pressure mercury lamp, a high-pressure mercury lamp, a medium-pressure mercury lamp or a low-pressure mercury lamp, a chemical lamp, a carbon arc lamp, a xenon lamp, a metal halide lamp, a visible laser lamp, an ultraviolet laser lamp, a fluorescent lamp, a tungsten lamp or sunlight can be used as a light source.

The present invention will be described below in greater detail by referring to the examples, but the present invention should not be construed as being limited to these examples.
