Abstract

Provided is a coating agent that can be formed into a surface layer having excellent self-restoring properties and stain-proof properties by applying the coating agent onto a surface of a base material (for example, thermoplastic polyurethane) and curing the resulting material. The coating agent according to the present application contains urethane (meth)acrylate-based resin (a), fluorine-based compound (b) and photopolymerization initiator (d). Urethane (meth)acrylate-based resin (a) has weight average molecular weight (Mw) of 10,000 to 800,000. Fluorine-based compound (b) has at least two polymerizable functional groups. The surface layer formed of the coating agent has excellent self-restoring properties of a scratch, stain-proof properties and stretchability.
