PHOTOCURABLE RESIN AND PHOTOCURABLE RESIN COMPOSITION

摘要

Disclosed is a photocurable resin (A) which has a molecular structure represented by general formula (I). Also disclosed is a carboxyl group-containing photocurable resin (A') which is produced by reacting the photocurable resin (A) with an acid anhydride (d). Further disclosed is a photocurable resin composition which comprises the photocurable resin (A) and/or the carboxyl group-containing photocurable resin (A') and a photopolymerization initiator (B) as the essential components. (In the formula, Ac represents a (meth)acryloyloxy group; R1 represents a residue of an epoxy compound (a), which contains an ethylene group produced by the ring opening of an epoxy group in the compound (a); R2 represents a joint part containing a carbonyloxy group or an urethane bond; n represents an integer of 1 to 99; and m represents 0 or 1.)
