The invention provides a fluorine-containing acetophenone derivative which is useful as an additive that can impart excellent antifouling properties and scratch resistance to the surface of a cured coating and that also offers high transparency of the coating; a fluoroadditive and an active energy ray curable composition which each include the above derivative; a cured product of the composition; and an article having a cured coating of the composition. Specifically, this object is achieved by using a fluorine-containing acetophenone derivative, typically represented by the structural formula below, that is obtained by introducing an acryloyl group into a poly(perfluoroalkylene ether) chain and thereafter introducing, using Michael addition reaction, an α-aminoacetophenone-based structural unit capable of generating radical species by photocleavage
