Title:

(METH)ACRYLAMIDE-BASED URETHANE OLIGOMER AND ACTIVE-ENERGY-RAY-CURABLE RESIN COMPOSITION CONTAINING SAME

Document Type and Number:

WIPO Patent Application WO/2017/047615

Kind Code:

A1

Abstract:

[Problem] The present invention addresses the problem of providing a (meth)acrylamide-based urethane oligomer having excellent compatibility with organic solvents and general-purpose acrylic monomers or oligomers and which has high curing ability with respect to active energy rays and low curing shrinkage, and of providing an active-energy-ray-curable resin composition having low curing shrinkage, and a molded article of the same. [Solution] Through use of a (meth)acrylamide-based urethane oligomer characterized by having a (meth)acrylamide group at a terminal end or side chain thereof and a curing shrinkage rate of 5% or less, it is possible to prepare a urethane oligomer having high curability and excellent compatibility with organic solvents and general-purpose acrylic monomers or oligomers, and an active-energy-ray-curable resin composition containing the same and having excellent adhesion, anti-tack properties, moisture resistance, and shrinkage resistance.
