PURPOSE: To obtain an image forming photosensitive resin compsn. superior in storage stability, hardenability, heat resistance of a film, etc., by mixing a photopolymerizable unsatd. compd. having plural terminal ethylenic groups, a photopolymerization sensitizer, and a specified linear polymer compd.
CONSTITUTION: An objective photosensitive resin compsn. is obtained by mixing (A) a photopolymerizable unsatd. compd. having plural terminal ethylenic groups, e.g., triethylene glycol acrylate, (B) a photopolymn. sensitizer, e.g., benzophenone, (C) a linear prepolymer obtained by polymerizing a compd. represented by formula I in which R1 is H, methyl, ethyl, or halogen, and R2, R3, R4 are each aliphatic or aromatic hydrocarbon group or the like, e.g., 1,1-dimethyl-1-(2-hydroxy-3-butoxypropyl)amine-methacylimide with a polymerizable compd. having an epoxy group, e.g., glycidyl acrylate.
