ACTIVE ENERGY RAY-CURABLE RESIN AND METHOD FOR PREPARING THE SAME

摘要

An active energy ray-curable resin composition is provided to ensure excellent pattern forming ability and mechanical property of patterns. An active energy ray-curable resin composition comprises a modified copolymer(B) obtained by adding an epoxy group-containing unsaturated compound to a part of acid group of a copolymer(A). The copolymer(A) is obtained from C5-18 linear or branched alkyl group-containing (meth)acrylic acid ester(a), (meth)acrylic acid(b), and (meth)acrylic acid ester(c) which dose not a C5-18 linear or branched alkyl group.
