<p>PROBLEM TO BE SOLVED: To provide the photopolymerizable composition high in sensitivity and adapted to a material for forming various patterns for a litho-graphic printing plate, a printed board, a color filter, or the like. SOLUTION: The photopolymerizable composition comprises an additionally polymerizable compound having at least one ethylenically unsaturated double bond and a photopolymerization initiator system containing at least one radical activator. In this case, the photopolymerization initiator system contains compounds selected from >=2 groups of the following 3 groups; (a) an amino acid or its condensate or its bipolar ion compound, (b) an amino acid salt or its condensate, (c) an amino acid ester or its condensate.</p> |
