PROBLEM TO BE SOLVED: To provide an adhesive protective film having a small hardness and excellent rebound resistance, and having a high hardness and a high scratch resistance even in a thin thickness. SOLUTION As a protective layer, urethane acrylate obtained by addition reaction of polyisocyanate with acrylate having one hydroxyl group and two or more (meth) acryloyl groups in one molecule, and (meth) acryloyl group in the side chain. The protective adhesive film using the active energy ray hardening-type resin composition containing the (meth) acrylate type polymer which has this. [Selection figure] None |
