(57) [Abstract] [Purpose] A dry film that can form a uniform film thickness, has excellent adhesion to the object to be processed, and is highly practical, and has a cold flow when used as a dry film. It can be stored for a long time without problems such as It is an object of the present invention to provide a photosensitive resin composition capable of forming a highly sensitive and fine pattern, excellent in alkali developability, and excellent in sandblast resistance. A carboxy-modified urethane (meth) acrylate compound having at least two or more (meth) acryloyl groups, an acid value of 20 to 70 mg / KOH, and a glass transition point after curing of 5 ° C to 95 ° C. , Acid value is 50 ~ A photosensitive resin composition comprising an alkali-soluble polymer compound of 250 mg / KOH and a photopolymerization initiator. |
