<p>PROBLEM TO BE SOLVED: To ensure high sensitivity without carrying out coating with an oxygen isolating layer by using a combination of a sensitizer represented by a specified structural formula with a radical generating agent as a photopolymn. initiating system. SOLUTION: This compsn. contains a compd. having at least one ethylenically unsatd. double bond, a photopolymn. initiating system and a coloring material. The photopolymn. initiating system is a combination of at least one kind of sensitizer having a structure represented by the formula with a radical generating agent. The coloring material is contained by >=50wt.% of the total amt. of all solid components. In the formula, each of Ra -Rd is H or 1-20C alkyl which may have a substituent, Re is H, halogen, 1-10C alkyl and A is an arom. cyclic group which may have a substituent and includes 1-3 nuclei or a heterocyclic arom. group which may have a substituent and includes 1-3nuclei.</p> |
