PURPOSE:To improve solvent resistance, printing resistance and productivity by using a photopolymerizable compsn. increased in photosensitivity by forming the photopolymerizable compsn. on an indicator and specifying the constitution of this photopolymerizable compsn. CONSTITUTION:The compsn. contg. a bisacridine compd. having two pieces of acrydyl groups in one molecule as a photopolymn. initiator and a compsn incorporating a compd. having an ethylenic unsatd. group is used. Namely, the photopolymerizable compsn. of the photopolymerizable compsn. layer formed on a base is constituted of 100 pts.wt. compd. having at least one piece of the ethylenic unsatd. group, 40 to 400 pts.wt. thermoplastic org. polymer and 0.01 to 20 pts.wt. acridine compd. expressed by formula. In the formula, R denotes 2 to 20C alkylene group, oxadialkylene group or thiodialkylene group. The acridine compd. expressed by formula is easily produced by bringing, for example, diphenyl amine and bivalent carboxylic acid into reaction in the presence of a metal chloride.
