PURPOSE: To obtain a hardened material good in water and solvent resistances through photosetting by adding a water-insoluble vinyl monomer and an polymn. initiator to a mixture of a partially saponified polyvinyl acetate and a hydrophobic polymer emulsion.
CONSTITUTION: A photosensitive resin compsn. is made of an aq. emulsion contg. (A) a photopolymerizable partially saponified polyvinyl acetate, such as partially saponified polyvinyl acetate having a stilbazolium salt introduced into it, represented by the general formula shown here, (B) a hydrophobic emulsion of a copolymer, such as vinyl acetate-ethylene, vinyl acetate-acrylate, or styrene-butadiene copolymer, (C) a water-insoluble or hardly soluble photoactive compd. having at least one ethylenically unsatd. group, (D) a photopolymn. initiator, (E) and when needed, a photo-crosslinking agent, such as bichromate or diazo resin.
