Provided is an active energy ray curable resin which has excellent compatibility with organic solvents, general purpose acrylic monomers, and oligomers, and a high curing property with an active energy ray, and also has a high adhesion property for each substrate. A cured film obtained by ultraviolet curing of the active energy ray curable resin has an excellent surface curing property, scratch resistance and bending resistance, while also having high transparency. Provided is a urethane modified (meth)acrylamide compound having a urethane bond and one or more (meth)acrylamide groups in the molecule. The urethane modified (meth)acrylamide compound has excellent compatibility with organic solvents, general purpose acrylic monomers, and oligomers, and exhibits a high curing property with an active energy ray. Also provided is an active energy ray curable resin which is obtained with the urethane modified (meth)acrylamide compound and has an excellent surface curing property, scratch resistance, and bending resistance.
