PROBLEM TO BE SOLVED: To make it possible to obtain an excellent sensitivity, resolving power, adhesion, preservation stability, etc., by incorporating a specific amount of a specific photopolymerization initiator as an ethylenically unsaturated com pound into the above composition and further, incorporating an N-aryl-α-amino acid-base compound as a photopolymerization initiator therein. SOLUTION: The photosensitive resin composition consisting of a carboxyl group-containing polymer, the ethylenically unsaturated compound and the photopolymerization initiator contains the photopolymerization monomer expressed by formula as the ethylenically unsaturated compound at 3 to 50 wt.% of the entire part of the ethylenically unsaturated compound and further, contains the N-aryl-α-amino acid-base compound as the photopolymerizable initiator. In the formula, R1 is hydrogen or methyl group; R2 is 1-4C alkyl group; R3 is 4-14C alkyl group; (m) is an integer from 3 to 20; (n) is an integer from 0 to 9; (l) is an integer from 1 to 3. The content of the photopolymerization monomer is further preferably 5 to 30 wt.%, more preferably 5 to 20 wt.%. |
