PROBLEM TO BE SOLVED: To ensure high photosensitivity to visible light by incorporating an ethylenically unsatd. compd. which is not gaseous at ordinary temp., a titanocene compd., a specified 3-substd. coumarin compd. and a specified glycine deriv. SOLUTION: This compsn. contains at least one kind of ethylenically unsatd. compd. which is not gaseous at ordinary temp., a titanocene compd., a 3-substd. coumarin compd. represented by formula I and a glycine deriv. represented by formula II. In the formula I, each of R1 -R4 is H, alkyl, alkoxy, cyano, etc., two of them may form a condensed ring or a condensed hetero ring, Z is aryl, a heterocyclic group, etc., and R5 is alkyl, alkoxy, etc. In the formula II, each of R<6> -R<10> is H, optionally substd. acyl or halogen substd. alkyl, all of them are not simultaneously H and each of R<11> -R<13> is H, optionally substd. alkyl, etc. |
