PHOTOCURABLE RESIN COMPOSITION AND LIGHT-EMITTING ELEMENT SEALANT

摘要

Disclosed is a photocurable resin composition that cures quickly, thereby improving productivity, and can provide a light-emitting element sealant that is highly heat-resistant and optically transparent. Also disclosed is a light-emitting element sealant using said photocurable resin composition. The photocurable resin composition contains: (A) 100 mass parts of an end-modified hydrogenated styrene-butadiene rubber; and (B) 0.1 to 13 mass parts of an a-hydroxyalkyl-phenol photopolymerization initiator and/or an acyl phosphine oxide photopolymerization initiator.
