Beschreibung
Zusammenfassung:	The present invention provides a photosensitive resin composition from which a dry resist film having excellent resilience, storage stability and heat resistance can be produced. The photosensitive resin composition according to the present invention includes a photosensitive prepolymer having a carboxyl group and an ethylenically unsaturated group, a photopolymerization initiator and a thermal curing agent, wherein the thermal curing agent is a polycarbodiimide compound having a carbodiimide group, the carbodiimide group in the polycarbodiimide compound is protected by an amino group that can be dissociated at a temperature equal to or higher than 80° C. and the polycarbodiimide compound has a weight average molecular weight of 400 to 5000 and a carbodiimide equivalent of 180 to 2500.
