PROBLEM TO BE SOLVED: To obtain a high sensitivity photopolymerizable composition having good developability and free from problem on handling such as a foul odor by incorporating an addition polymerizable compound having an ethylenically unsaturated double bond, a radical activator, a sensitizing dye and an aliphatic amino acid salt and using a pyromethene borate dye as the sensitizing dye. SOLUTION: The photopolymerizable composition contains an addition polymerizable compound having an ethylenically unsaturated double bond, a radical activator, a sensitizing dye and an aliphatic amino acid salt and a pyromethene borate dye is contained as the sensitizing dye. The pyromethene borate dye may be a dye having a structure of the formula, wherein R1-R6 are each H, halogen, alkyl, aryl or the like, R7 is H, alkyl, aryl or aralkyl, X1 and X2 are each halogen, alkyl, aryl, aralkyl or the like and H atoms of the groups R1-R7 may further be substituted. |
