Abstract: [Problem] To provide a coating film which is capable of maintaining good water repellency and antifouling properties. [Solution] A photopolymerizable coating composition which contains, as photopolymerizable components, a urethane (meth)acrylate (component (a)) and a photopolymerizable (meth)acrylic compound (component (b)), and which is configured such that: from 1% by weight to 50% by weight (inclusive) of the component (a) and from 50% by weight to 99% by weight (inclusive) of the component (b) relative to the total amount of the photopolymerizable components are mixed; and the component (b) contains a photopolymerizable acrylic compound (component (b1)) which has a structural unit derived from a fluorosilsesquioxane derivative represented by formula (1), a reactive silicone (component (b2)) and a photopolymerizable acrylic compound (component (b3)) which has no urethane unit, no fluorine atom and no Si atom.

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.
