Radiation-sensitive colored composition, colored cured film, color filter and method of producing the same, solid-state imaging device, liquid crystal display apparatus, and method of producing dye

A radiation-sensitive colored composition comprising:

• (A) a dye containing of from 10 ppm to 1000 ppm of a halogen ion;
• (B) a polymerizable compound;
• and
• (C) a solvent, and
• further comprising a pigment,
• wherein:
• the dye (A) is a multimer having two or more partial structures derived from a colorant compound, and the colorant compound is at least one selected from the group consisting of a dipyrromethene colorant, an anthraquinone colorant, a triphenylmethane colorant, a xanthene colorant, a cyanine colorant, a squarylium colorant, a quinophthalone colorant, a phthalocyanine colorant and a subphthalocyanine colorant,
• the pigment is at least one selected from a group consisting of C.I. Pigment Violet 23, C.I. Pigment Blue 15:3, and C.I. Pigment Blue 15:6, and
• the multimer contains a repeating unit having an ethylenically unsaturated bond after polymerization.
