Abstract:
The present invention provides a photosensitive resin composition comprising 100 parts by mass of a polyurethane prepolymer having an ethylenically unsaturated group, 10 to 150 parts by mass of an ethylenically unsaturated compound, and 0.01 to 10 parts by mass of a photopolymerization initiator, wherein the ethylenically unsaturated compound comprises 0.1 to 10 parts by mass of a polyfunctional ethylenically unsaturated compound having 6 or more (meth)acryloyl groups in a molecule thereof with respect to 100 parts by mass of the polyurethane prepolymer.
