Beschreibung
Zusammenfassung:	An actinic radiation curable resin composition characterized by comprising a urethane acrylate (A) which is a product of addition reaction of a polyisocyanate (a1) with an acrylate (a2) having one hydroxyl group and two or more (meth)acryloyl groups in the molecule and a polymer (B) having a (meth)acryloyl group which is obtained by reacting a (meth)acrylate polymer (b1) having a reactive functional group in the side chain with an alpha,beta-unsaturated compound (b2) having a functional group reactive with the reactive functional group. The composition can be cured by irradiation with an actinic radiation such as ultraviolet light to give a cured film having high hardness and high mar resistance with little cure shrinkage.
