Abstract
A photosensitive resin coloring composition for use in a color filter containing a resin and a dye. The dye is manufactured with one member selected from the class consisting of a combination of (A)+(B) groups, a combination of (A)+(C) groups, a combination of (B)+(C) groups, and a combination of (A)+(B)+(C) groups, wherein (A) represents a group of quinizarine compounds, (B) represents a group of anthraquinone compounds, and (C) represents a group of phthalocyanine compounds.
Claims29
A photosensitive resin coloring composition for use in a color filter containing a resin and a dye which is a material for the formation of a colored layer of the color filter, characterized in that said dye is selected from a combination of (A)+(B) groups, a combination of (A)+(C) groups, a combination of (B)+(C) groups, and a combination of (A)+(B)+(C) groups, wherein (A) represents a group of quinizarine compounds having a quinizarine skeleton in which one to three of the 5, 6, 7, and 8 positions and at least either of the 6 and 7 positions are each occupied by a secondary amino group and the remainders of the 5, 6, 7, and 8 positions are occupied each by at least one group selected from the class consisting of hydrogen atom, halogen atom, an unsubstituted or substituted alkoxy group, an unsubstituted or substituted phenoxy group, or unsubstituted or substituted alkylthio group, and an unsubstituted or substituted phenylthio group, (B) represents a group of anthraquinone compounds having an anthraquinone skeleton in which one to three of the 1, 2, 3, and 4 positions are occupied each by at least one group selected from the class consisting of secondary amino group, an unsubstituted or substituted alkoxy group, an unsubstituted or substituted phenoxy group, an unsubstituted or substituted alkylthio group, and an unsubstituted or substituted phenylthio group and the remainders of the 1, 2, 3, and 4 positions are occupied each by hydrogen atom or a halogen atom, and (C) represents a group of phthalocyanine compounds having a phthalocyanine skeleton represented by the following general formula (1) ##STR57## wherein M represents a divalent metal or a ligand-containing tetravalent metal in which one to eight of the 16 positions of benzene rings permitting substitution are occupied each by an unsubstituted or substituted alkoxy group and/or an unsubstituted or substituted phenoxy group and the remainders of the positions are occupied each by a halogen atom.
