Phthalocyanine compounds and usage thereof

BACKGROUND OF THE INVENTION
1) Field of the Invention
This invention relates to green dyes, which can play an important role in color filters for display devices such as liquid crystal television sets or in color separation filters for image pickup tubes or color copying machines, and also to color filters. The present invention is also concerned with near infrared absorbers, which can play an important role in optoelectronics-related fields such as recording of information, image sensors and protective goggles, and also with optical recording media fabricated using the near infrared absorbers.
2) Description of the Related Art
Known conventional filters using a phthalocyanine compound include inter alia those disclosed in Japanese Patent Laid-Open Nos. 30509/1984, 249102/1985, 140902/1986, 254903/1986, 254904/1986, 6904/1989, 88505/1989 and 233401/1989.
Among such phthalocyanine compounds, water-soluble compounds containing one or more sulfonic groups are suited for coloring filters in which gelatin or casein is used as a base material, and have been employed in gelatin-base filters. These filters have, however, been used only to a limited extent due to the poor heat resistance and moisture resistance of the filters per se. The phthalocyanine compounds containing substituents at the .beta.-positions thereof, which are disclosed in Japanese Patent Laid-Open No. 233401/1989, are excellent in durability but are not sufficient in transmission characteristics. On the other hand, phthalocyanine compounds containing substituents at the .alpha.-positions, which are disclosed in WO 88/06175 and GB 2168372A, are accompanied by the drawback that they have poor solubility in resins and, to obtain a color density useful as a green filter, the film thickness of the filter must be increased. Further, their transmittance characteristics as green dyes are not sufficient.
Usage of phthalocyanine compounds as near infrared absorbers is widely known, for example, from Japanese Patent Laid-Open Nos. 209583/1985, 152769/1986, 154888/1986, 197280/1986, 246091/1986 and 39286/1987. The absorption ability of these phthalocyanine compounds was however not sufficient as they are prone to association. Optical recording media making use of one or more of such phthalocyanine compounds are, therefore, accompanied by drawbacks such as low reflectance at 780-830 nm and insufficient sensitivity and recording characteristics.
SUMMARY OF THE INVENTION
An object of this invention is to improve the poor solubility in a binder resin, transmittance characteristics, light resistance and heat resistance, which are the drawbacks common to such conventional green filters as described above and also to such green filter dyes as referred to above.
Another object of this invention is to provide a novel near infrared absorber free of the above-mentioned drawbacks and also an optical recording medium fabricated using the novel near infrared absorber and having high reflectance and good sensitivity and recording characteristics.
A further object of this invention is to provide a near infrared absorber, which has high solubility in liquid crystal compounds employed in liquid crystal devices and also exhibits good sensitivity to laser beam writing.
The present inventors have conducted extensive research with a view toward attaining the above objects. As a result, it has been found that the solubility in a resin can be improved by the use of a phthalocyanine compound substituted at the .alpha.-position thereof by particular substituents, preferably each substituent containing one or more hetero atoms, desirably one or more nitrogen atoms, thereby making it possible to obtain a filter having good transmittance characteristics and excellent durability such as heat resistance and light resistance. As reasons for the good transmittance characteristics of the phthalocyanine compounds with hetero-atom-containing substituents at the .alpha.-positions, it may be mentioned that the introduction of the hetero atom in the side chain makes the polarity of the dye similar to that of the resin and, as a result, the compatibility between the resin and the dye is improved and the dye is stably distributed as discrete molecules in the resin.
It has also been found that the phthalocyanine compounds substituted at the .alpha.-positions by N-containing substituents exhibit sharp absorption at 650-900 nm, have a high molecular absorption coefficient and are excellent as near infrared absorbers. Optical recording media making use of one or more of these near infrared absorbers have been found to have high reflectance and sensitivity in the near infrared range. As reasons for the good absorbing ability of the phthalocyanine compounds substituted at the .alpha.-position by N-containing substituents, it can be mentioned that association of molecules is suppressed owing to the action of nitrogen atoms.
The present invention, therefore, provides a color filter and a near infrared absorber, both comprising a phthalocyanine compound represented by the following formula (I), and an optical recording medium and a liquid crystal display device, both fabricated using the same: ##STR3## wherein R.sup.1, R.sup.4, R.sup.5, R.sup.8, R.sup.9, R.sup.12, R.sup.13 and R.sup.16 independently represent a group represented by the below-described formula (II) or a hydrogen or halogen atom with the proviso that, in each of the combinations of R.sup.1 and R.sup.4, R.sup.5 and R.sup.8, R.sup.9 and R.sup.12, and R.sup.13 and R.sup.16, at least one of the groups is represented by the formula (II); R.sup.2, R.sup.3, R.sup.6, R.sup.7, R.sup.10, R.sup.11, R.sup.14 and R.sup.15 independently represent a substituted or unsubstituted C.sub.1-20 alkyl, substituted or unsubstituted C.sub.1-20 alkoxyl group, substituted or unsubstituted C.sub.1-20 alkylthio, substituted or unsubstituted C.sub.1-20 alkylamino, substituted or unsubstituted C.sub.2-20 dialkylamino, substituted or unsubstituted aryloxyl, substituted or unsubstituted arylthio, --COOR.sup.17, R.sup.17 being a hydrogen atom or a substituted or unsubstituted alkyl group, hydroxyl or mercapto group or a halogen or hydrogen atom; and Met represents a metal atom. ##STR4## wherein X and Z represent an oxygen or sulfur atom, R.sup.18, R.sup.19 and R.sup.20 independently represent a hydrogen atom or a substituted or unsubstituted C.sub.1-20 alkyl group, A, B and D represent a connecting group, n and l stand for an integer of 0-10, m, q, t, u, r and w are an integer of 0-2, and p represents 0 or 1.

Met-(Y).sub.d (VII)
wherein Met is the same as Met in formula (I), Y means a monovalent or divalent ligand such as a halogen atom, an anionic acetate ion, acetylacetonato or oxygen atom, and d stands for an integer of 1-4, for example, in the presence of 1,8-diazabicyclo[5.4.0]-7-undecene (DBU), in a solvent such as an alcohol, an alkylaminourea, a halogenated hydrocarbon or quinoline, at 80.degree.-230.degree. C., for about 2-20 hours.
To fabricate a color filter for LCD or a color separation filter for image pickup tube by using one of the phthalocyanine compound of this invention, various processes can be used. For example, a photosensitive resin or photopolymerizable monomer is formed into a film on a substrate by casting, spin coating or the like. After the film being patterned by exposure to light, the resin layer is colored with the dye by dipping or the like. The filter is patterned by dry etching or lifting-off and then colored with the dye by vaccum deposition. The dye is either dissolved or dispersed beforehand in a photosensitive resin or photopolymerizable monomer. The solution or dispersion so prepared is formed into a film on a substrate by casting, spin coating or the like. The film is then patterned by exposure to light. As a still further alternative, such a solution or dispersion is applied in the form of a pattern by a printing method.
As has been described above, the patterning of a dye layer can be conducted on an optically transparent substrate. No particular limitation is imposed on the substrate to be used, insofar as it permits patterning of the dye layer and the color filter so formed functions as desired.
Examples of the substrate include glass plates; and films or plates of resins such as polyvinyl alcohol, hydroxyethylcellulose, methyl methacrylate, polyesters, polybutyral, polyamides, polyethylene, polyvinyl chloride, polyvinylidene chloride, polycarbonates, polyolefin copolymers, vinyl chloride copolymers, vinylidene chloride copolymers and styrene copolymers. A patterned dye layer can also be formed integrally with a substrate which is applied as a color filter. Examples of such a substrate includes the display screen of a cathode ray tube, the image receiving screen of an image pickup tube, a wafer with a solidstate image pickup device such as CCD, BBD, CID or BASIS formed thereon, a contact-type image sensor using a thin-film semiconductor, a liquid crystal display screen, and a photosensitive body or substrate for color electrophotography.
Taking the formation of a stripe filter as an example, a typical process for the formation of a filter will hereinafter be described with reference to the drawings.
First, one of the phthalocyanine compounds according to this invention is dissolved or dispersed at a proportion of 1-100 wt. %, preferably 40-100 wt. % in a photosensitive resin, and the resulting solution or dispersion is spin-coated on a substrate 1 by using a spinner (FIG. 1). The thickness of a resist layer 2 is usually 0.5-100 .mu.m although it is determined depending on spectroscopic characteristics desired. After the resist layer 2 is dried, the resist layer 2 is prebaked under suitable temperature conditions. The resist layer is exposed to light or an electron beam, to which the resist has sensitivity, via a mask 3 having a desired pattern corresponding to a pattern to be formed (i.e., a stripe pattern)--FIG. 2. The resist layer so exposed is then developed to form a pattern 4 (FIG. 3). If necessary, pre-treatment may be applied before the development to release any strain of the resist layer, or rinsing treatment may be conducted after the development to suppress any expansion of the resultant film. Finally, post-baking is applied under appropriate temperature conditions.
To form a color filter having two or more colors, the steps of from FIG. 1 to FIG. 3 are repeated using dyes corresponding to the respective colors as needed, namely, as many times as the number of filter colors employed, thereby making it possible to form, for example, a color filter having three colored layers 5,6,7 of different colors as shown in FIG. 4. To form a black matrix, the formation of colored layers may preferably be conducted after the formation of the black matrix.
To fabricate a color filter for a color copying machine or the like by using one of the phthalocyanine compound of this invention, various processes can be used. For example, it can be fabricated by mixing a thermoplastic resin, such as polystyrene, polymethyl methacrylate, polycarbonate, polyester or polyvinyl chloride, with 0.5-10 wt. %, based on the resin, of the dye of this invention and then injection-molding or drawing the resultant resin composition. It can also be fabricated by dissolving the dye of this invention either singly or together with a binder in a solvent and forming the resultant solution into a film on a substrate in accordance with casting, spin coating or the like. As a further alternative, the dye of this invention can be formed into a film on a substrate by vacuum evaporation. As a still further alternative, the dye of this invention is mixed with a varnish which contains a resin intermediate, and the resulting mixture is processed and then heat-treated into a resin.
As the material for the substrate in the above process, any resin can be used as long as it is optically transparent. Illustrative usable resins include acrylic resins, polyethylene, vinyl chloride resin, vinylidene chloride resin, polycarbonates, polyethylene copolymers, polyolefin copolymers, vinyl chloride copolymers, vinylidene chloride copolymers, and styrene copolymers.
To fabricate an optical recording medium by using one of the dyes according to the present invention, the dye can be coated or vacuum-evaporated on a transparent substrate. According to the coating process, a binder resin and the phthalocyanine compound are dissolved in a solvent such that the concentration of the binder resin is not higher than 20 wt. %, preferably 0 wt. % and that of the phthalocyanine compound is 0.05-20 wt. %, preferably 0.5-20 wt. %, and the resultant solution is coated by a spin coater. According to the vacuum evaporation process, the phthalocyanine compound is deposited on the substrate at 10.sup.-5 -10.sup.-7 torr and 100.degree.-300.degree. C.
To allow the phthalocyanine compound of this invention to exhibit good performance different from conventional dyes, spin-coating or dipping should be used. In particular, it is the best process to coat only the phthalocyanine compound of this invention. On the other hand, the optical recording medium can be either of the WORM type that only a recording layer comprising the phthalocyanine compound of this invention is provided on a substrate or of the CD-WORM type that the above recording layer is provided on a substrate, a reflective layer made of gold or aluminum is provided over the recording layer and an over-coat is applied further.
Any resin can be used for the production of the substrate as long as it is optically transparent. Illustrative usable resins include acrylic resins, polyethylene, vinyl chloride resin, vinylidene chloride resin, polycarbonate resins, polyethylene copolymers, polyolefin copolymers, vinyl chloride copolymers, vinylidene copolymers and styrene copolymers.
The substrate may have been surface-treated with a thermosetting resin or an ultraviolet curing resin.
To fabricate an optical recording medium (optical disc, optical card or the like), it is preferable from the standpoints of manufacturing cost and the handling ease by users to employ a polyacrylate substrate or polycarbonate substrate as a substrate and to coat and form a recording layer by spin coating.
In view of the solvent resistance of the substrate, illustrative solvents usable upon spin coating include halogenated hydrocarbons such as dichloromethane, chloroform, carbon tetrachloride, tetrachloroethylene and dichlorodifluoroethane; ethers such as tetrahydrofuran and diethyl ether; ketones such as acetone and methyl ethyl ketone; alcohols such as methanol, ethanol and propanol; cellosolves such as methylcellosolve and ethylcellosolve; and hydrocarbons such as hexane, cyclohexane, octane, benzene, toluene and xylene.
The present invention will hereinafter be described in detail by the following examples. It should be borne in mind that embodiments of this invention should not be limited to or by the following examples.
