Coloring composition, coloring radiation-sensitive composition, color filter and solid-state imaging device

摘要

Disclosed is a coloring composition with satisfactory heat resistance, no discoloration, excellent developability, and no development residues on a substrate and pixels of other colors, providing, a coloring composition for a color filter including (A) a polymer having a dye skeleton and (B) an organic solvent, wherein the content of an unreacted monomer component having the dye skeleton which is capable of forming (A) the polymer having the dye skeleton is less than or equal to 1 mass % with regard to (A) the polymer having the dye skeleton.

主权项

1. A coloring composition for a color filter comprising:
(A) a polymer having a dye skeleton and (B) an organic solvent, wherein the content of an unreacted monomer component having the dye skeleton which is capable of forming (A) the polymer having the dye skeleton is less than or equal to 1 mass % with regard to (A) the polymer having the dye skeleton, wherein the dye skeleton is derived from xanthene dyes represented by the following General Formula (J): in General Formula (J), R81, R82, R83, and R84, each independently, represents a hydrogen atom or a monovalent substituent, R85s, each independently, represent a monovalent substituent, m represents an integer of 0 to 5, and X− represents an anion, and the polymer having the dye skeleton includes an ethylenic unsaturated bond after polymerization.
