PURPOSE:To obtain the resin composition high in sensitivity and superior ink preservability and adhesion to a substrate and high in practicability by using a polymer compound having structural units each having a specified phenylazido group introduced as a photosensitive group. CONSTITUTION:The polymer compound has structural units each represented by formula I in which X is a cation. This compound is synthesized by introducing at least one of 4-azidobenz-aldehyde-2-sulfonic acid and its salts into a water-soluble polymer obtained by copolymerizing, for example, diaceton- ediacrylamide with a water-soluble monomer, by the aldole condensation reaction. |
