The present invention provides an active energy ray-curable polymer composition having a good coatability and a cured film having excellent wear resistance, hardness and mechanical strength. An active energy ray-curable polymer composition containing a urethane (meth) acrylate oligomer, which is a reaction product of a raw material containing polyisocyanate, polycarbonate diol, and hydroxyalkyl (meth) acrylate. A polycarbonate diol having a number average molecular weight of 500 or more and 10,000 or less and containing a specific structural unit such as neopentyl glycol is used. [Selection figure] None |
