PURPOSE:To obtain a titled compsn. capable of forming a photoset film high in strength by adding a specified photopolymn. initiator to an additionally polymerizable unsatd. compd. having >=2 ethylenically unsatd. double bonds in its molecule. CONSTITUTION:To 100pts.wt. additionally polymerizable unsatd. compd. having >=2 ethylenically unsatd. double bonds in its molecule, such as diethylene glycol di(meth)acrylate, is added as a photopolymn. initiator, 0.01-100pts.wt. 4,4'-bis (dialkylamino)benzophenone having formula I (R is 1-6C alkyl, cycloalkyl, hydroxyalkyl, or it may form tetramethylene, pentamethylene, or oxybisethylene together with another R substituting the same N), 0.01-100pts.wt. benzophenone deriv. having formula II (R<1> is H of formula III; X1, X2 are each alkyl, alkoxy, carboxy or the like; m, n are each 0, 1, or 2, and when each is 2, X1 and X2 may be same or different), and 0.01-100pts.wt. compd. having a group having formula IV.
