The present invention provides a fluorine-containing acetophenone derivative, a fluorine-based additive containing the same, an active energy ray-curable composition, a hardened product thereof, and an article having a hardened coating film thereon; It is useful as an additive to impart excellent antifouling properties and scratch resistance to the surface of the cured coating film, and to obtain a coating film that is also excellent in transparency. Specifically, the foregoing problem is solved by using a fluorinated acetophenone derivative represented by the following structural formula; the fluorinated acetophenone derivative represented by the following structural formula introduces acryl After the (perfluoroalkylene ether) chain, a Michael addition reaction is used to introduce an α-aminoacetophenone system, which is obtained by photolysis of a structural unit that can generate a radical species. |
