COLORING COMPOSITION FOR COLOR FILTER, COLOR FILTER AND METHOD FOR MANUFACTURING COLOR FILTER

摘要

PROBLEM TO BE SOLVED: To provide a coloring composition for color filters, capable of forming a pixel part excellent in developability, contrast and brightness.SOLUTION: A coloring composition for color filters comprises: an organic pigment (A) consisting of polyhalogenated zinc phthalocyanine having an average primary particle size of 10-40 nm and C.I. pigment yellow 150; a copolymer (B) including a repeating unit represented by a following general formula (I), a repeating unit derived from (meth) acrylic acid and a repeating unit derived from benzyl (meth) acrylate; a polymerizable compound (C); a photopolymerization initiator (D); and an organic solvent (E). The C.I. pigment yellow 150 of 20- 80 parts is used to the polyhalogenated zinc phthalocyanine of 100 parts. (In the general formula (I), Ris a hydrogen atom or a methyl group, Ris a 2 or 3C alkylene group, Ris a hydrogen atom or a 1-20C alkyl group, and n is an integer of 1-15.)
