(57) [Summary] [Object] The object of the present invention is to provide a high photosensitivity even with a small amount of a photoinitiator added, a short development time and a short peeling time, and the peeled pieces are fragmented and the cured product is chemically Provided is a photosensitive resin composition having excellent physical resistance. [Constitution] (A) an ethylenically unsaturated compound having a propylene unit such as heptapropylene glycol diacrylate, (B) an ethylenically unsaturated compound such as trimethylolpropane triacrylate, (C) a weight average molecular weight of 20,000 to 300,000 Photosensitive resin composition soluble or swellable in alkaline aqueous solution containing a polymer compound having a carboxyl group and a photoinitiator such as (D) 1,7-bis (9-acridinyl) pentane Is applied on a support and dried. |
