PHOTOCURABLE RESIN COMPOSITION AND PROCESS FOR THE PREPARATION OF PHOTOCURABLE RESIN

摘要

A photocurable resin composition comprising (a) a conjugated diene polymer or copolymer having the following functional groups (I) and (II), a number average molecular weight of 500 to 5000 and a vinyl content of at least 50 mole % : functional group (I) functional group (II) wherein R1 represents a hydrocarbon residue having 1 to 20 carbon atoms which may contain a heteroatom; R2 and R3 each represent a hydrogen atom or a methyl group; and R4 represents a hydrocarbon residue having 2 to 20 carbon atoms which may contain a heteroatom, and (b) a photopolymerization initiator; and A process for the preparation of the same.
