Green curable composition, color filter and method of producing same

摘要

The invention provides a green curable composition including a colorant in an amount of 47.5% by mass or more with respect to the total solid content of the green curable composition, the colorant containing a halogenated copper phthalocyanine pigment and a barbituric acid derivative yellow pigment at a ratio of from 6/4 to 3/7 (halogenated copper phthalocyanine pigment/barbituric acid derivative yellow pigment); a colored pattern formed from the green curable composition; a color filter including the colored pattern; a solid-state image sensor including the color filter; and a method of producing the color filter.

1. A green curable composition comprising
a colorant in an amount of 47.5% by mass or more with respect to the total solid content of the green curable composition, the colorant containing a halogenated copper phthalocyanine pigment and a barbituric acid derivative yellow pigment at a ratio of from 6/4 to 3/7 (halogenated copper phthalocyanine pigment/barbituric acid derivative yellow pigment), an acidic group-containing monomer in an amount such that an acid value of the total content of the monomer is 25 mg KOH/g or more, and a pigment-dispersing resin having a structure represented by any one of the following Formulae (1) to (3): wherein in Formulae (1) to (3), each of A1, A2 and A3 independently represents an oxygen atom, a sulfur atom or —N(R21)—; R21 represents an alkyl group that may have a substituent; G1 represents a linear or branched alkylene group having 1 to 10 carbon atoms that may have a substituent, or an aromatic group having 6 to 12 carbon atoms that may have a substituent; each of G2 and G3 independently represents a bivalent organic group; each of X and Z independently represents an oxygen atom, a sulfur atom or —N(R22)—; R22 represents an alkyl group that may have a substituent; Y represents an oxygen atom, a sulfur atom, a phenylene group that may have a substituent, or —N(R23)—; R23 represents an alkyl group that may have a substituent; and each of R1 to R20 independently represents a hydrogen atom or a monovalent substituent.
