Title:

URETHANE OLIGOMER AND ACTIVE ENERGY RAY CURABLE RESIN COMPOSITION CONTAINING SAME

Document Type and Number:

WIPO Patent Application WO/2015/141537

Kind Code:

A1

Abstract:

[Problem] The purpose of the present invention is to provide a (meth)acrylamide-based urethane oligomer which has excellent compatibility with organic solvents and general purpose acrylic monomers and oligomers and a high curing speed when irradiated with active energy rays; and to provide an active energy ray curable resin composition, and a formed product thereof, which contains said urethane oligomers, has excellent adhesion, moisture resistance and surface curability and has low curing shrinkage. [Solution] By using a (meth)acrylamide-based urethane oligomer having a carbonate skeleton, a diene skeleton or a hydrogenated diene skeleton in the molecule and containing 5 wt% or less of a component having one or more (meth)acrylamide groups and a molecular weight of less than 1000 (excluding (meth)acrylamide compounds (A) having a hydroxyl group), it is possible to obtain an oligomer which has excellent compatibility with organic solvents and general purpose acrylic monomers and oligomers and high curability, and to obtain an active energy ray curable resin composition which contains said oligomer and has excellent adhesion, tack resistance, moisture resistance and shrinkage resistance.
