PURPOSE:To prevent the deterioration of the dyeability of the titled composition, even in case of increasing crosslinking density by incorporating a chromic compd. in a terpolymer composed of N-vinyl-2-pyridinone, a monomer having a quaternary amine structure and a polymerizable unsatd. bond and an acrylic compd. as the crosslinking agent. CONSTITUTION:The titled composition is formed by incorporating the chromic compd. in the terpolymer composed of N-vinyl-2-pyridinone, the monomer having the quaternary amine structure and the polymerizable unsatd. bond, and the compd. shown by the formula as the crosslinking agent. The titled composition has the structure formed by terpolymerizing the compd. having the function of photosensitivity, the compd. having the function of the dyeability and the compd. having the function of controlling solubility to water. The photocrosslinking density is not hardly affected to the dyeability, without hindering the dyeability of the composition due to the photocrosslinking by allotting the functions of the photosensitivity and the dyeability for the two kinds of the different compds., respectively. |
