PURPOSE: To obtain a resin composition suitable for manufacturing an identification card or the like combined with a photograph by blending a styrene-maleic acid copolymer resin as a stock polymer with an ethylenic unsatd. compound and a photopolymn. initiator.
CONSTITUTION: A styrene-maleic acid copolymer (a) having about 1,000W 2,000mol.wt. and about 130W220 acid value is blended with an about 10W60wt% ethylenic unsatd. compound (b) such as a mixture of 2-hydroxyethyl methacrylate and polyethylene glycol diacrylate, and a photopolymn. initiator (c), preferably a mixture of benzil and dimethylaminobenzaldehyde is further added by about 1W 10wt% to the total amount of the components (a), (b) to obtain a photopolymerizable photosensitive resin composition.
