PURPOSE:To enhance sensitivity to light having long wavelength such as visible light by incorporating an additional polymerizable compd. having an ethylenic unsatd. double bond and a photopolymn. initiating system contg. a specified sensitizer and a specified activator. CONSTITUTION:This photopolymerizable compsn. contains an additional polymerizable compd. having one or more ethylenic unsatd. double bonds and a photopolymn. initiating system contg. a sensitizer represented by the formula and am activator which can generate active radicals when irradiated with light in coexistence with the sensitizer. In the formula, each of R<1>-R<6> is H, halogen, alkyl, aryl, arylalkyl, acyl, alkoxycarbonyl, optionally substd. cyclic hydrocarbon, etc., R<7> is H, alkyl, aryl or arylalkyl and each of XM and X<2> is H, halogen, alkyl, aryl, arylalkyl, optionally substd. cyclic hydrocarbon or an optionally substd. heterocyclic group. |
