Photosensitive resin composition and photosensitive element using the same

摘要

A photosensitive resin composition comprising (A) a polymer obtained by reacting an isocyanate compound having an ethylenic unsaturated group with a polymer which is a reaction product of a tetracarboxylic acid dianhydride and a diamine, and (B) a photoinitiator, can provide a thick film excellent in heat resistant, adhesiveness, flexibility, electrical and mechanical properties, and is particularly suitable for producing a photosensitive element.
