ABSTRACT:
A radical-curing polyvinyl alcohol derivative is disclosed, which is obtained by reacting an anion-modified polyvinyl alcohol prepared by saponification of a copolymer comprising vinyl acetate and an unsaturated carboxylic acid and/or a derivative thereof with a glycidyl-containing vinyl compound in water or in a mixed solvent of water and a lower alcohol under acidic conditions, and which is useful as an image-forming material which is curable upon light irradiation and developable with water.
