Abstract

A coloring composition comprising: (1) 100 parts by weight of a crosslinked block copolymer which is produced by crosslinking a graft-modified block copolymer comprising molecular chains of a base block copolymer comprising at least one polymer block (A) comprised mainly of vinyl aromatic monomer units, and at least one polymer block (B) comprised mainly of conjugated diene monomer units, wherein each of the molecular chains of the base block copolymer has, grafted thereon, at least one functional group selected from the group consisting a hydroxyl group, an epoxy group, an amino group, a carboxylic acid group and a carboxylic acid anhydride group, the molecular chains of the base block copolymer being crosslinked through a crosslinkage containing at least one linkage selected from the group consisting of an imide linkage, an amide linkage, an ester linkage and a urethane linkage; and (2) from 0.001 to 20.0 parts by weight of at least one colorant selected from the group consisting of an organic pigment, an inorganic pigment and an organic dye, the coloring composition having a gel content of 60% by weight or more.
