<p>PROBLEM TO BE SOLVED: To obtain a color filter having excellent heat resistance and light resistance and having equal or superior color purity to that of a color filter produced by a dying method by incorporating a specifiedε-type phthalocyanine pigment and an acrylic unsatd. compd. and/or a transparent resin. SOLUTION: The compsn. contains anε-type phthalocyanine pigment and an acrylic unsatd. compd. and/or a transparent resin. The proportion of org. impurities in theε-type phthalocyanine pigment is required to be <=3 wt.% to the total of phthalocyanine and a phthalocyanine deriv. constituting a crystal stabilizer. The transparent resin has preferably >=80% transmittance for all over the 400 to 700 nm wavelength region of visible rays. As for the transparent resin, for example, a thermosetting resin, thermoplastic resin, photosensitive resin or a resin prepared from acrylic unsatd. compds. or vinyl compds. by irradiation of radiation can be used. The org. impurities means such compds. having no phthalocyanine skeleton.</p> |
