PROBLEM TO BE SOLVED: To ensure high sensitivity to active light in a wide region from UV to visible light by incorporating an addition polymerizable compd. having an ethylenically unsatd. double bond, a specified sensitizing dye and a titanocene compd. SOLUTION: This compsn. contains an addition polymerizable compd. having an ethylenically unsatd. double bond, a sensitizing dye represented by the formula and a titanocene compd. In the formula, each of R<1> , R<2> , R<7> and R<8> is H, alkyl, etc., each of R<3> -R<6> is H, halogen, etc., R<1> and R<2> may form a ring in combination with N by bonding to each other, R<1> and R<5> , and R<2> and R<3> may form separate rings in combination with C and N by bonding to each other, R<3> and R<4> , and R<5> and R<6> may form separate rings in combination with two C atoms by bonding to each other, X<1> is O or S and (n) is 0, 1 or 2. |
