    摘要: [Problem]
    An problem of the present invention is to provide to a (meth)acrylamide-based urethane oligomer which has excellent compatibility with organic solvents, general purpose acrylic monomers and oligomers, and a high curing speed to active energy rays, and to provide an active energy ray curable resin composition which contains the urethane oligomer, has excellent adhesion, moisture resistance and surface curability, and has low curing shrinkage, and a formed product thereof
    [Means for Solution]
    By using a (meth)acrylamide-based urethane oligomer of the present invention which has a carbonate skeleton, a diene-based skeleton or a hydrogenated diene-based skeleton in the molecule, one or more (meth)acrylamide groups and a component having a molecular weight of less than 1,000 (excluding a (meth)acrylamide compound (A) having a hydroxyl group) at a content of 5% by weight or less, it is possible to obtain a urethane oligomer which has excellent compatibility with organic solvents, general purpose acrylic monomers and oligomers, and a high curability and to obtain an active energy ray curable resin composition which contains the urethane oligomer and has excellent adhesion, tack resistance, moisture resistance and shrinkage resistance.
