(57) [Summary] [Structure] Polymeric binder containing carboxyl group and boiling point of 1 0.2 to 3 parts by weight of a leuco dye, 0.1 to 5 parts by weight of an organic bromo compound, and a trialkanolamine compound, relative to 100 parts by weight of a mixture of an ethylenically unsaturated compound and a photopolymerization initiator at 00 ° C or higher. And at least one compound selected from dialkanolamine compounds 0.01 to 1 By weight, malachite green 0.001 to 0.1 part by weight is contained. [Effect] The stability of the leuco dye can be improved, and a photosensitive resin composition having a stable color tone can be provided, and it can be suitably used particularly as a dry film resist for processing a printed wiring board. |
