<P>PROBLEM TO BE SOLVED: To provide a fluorine-containing polymerizable resin capable of imparting excellent scratch resistance to a surface of a cured coating film formed of an active-energy ray-curable composition by adding the resin to the composition, the scratch resistance being such as not to be deteriorated even when the surface is processed with chemicals such as strong alkalis, and also to provide an active-energy ray-curable composition including the fluorine-containing polymerizable resin, a cured product obtained from the composition, and an article including a cured coating film formed of the composition. <P>SOLUTION: The fluorine-containing polymerizable resin includes a polymer obtained by reacting a compound (D) with a polymer (P), the compound (D) having a polymerizable unsaturated group and a functional group (d) that has a reactivity to a reactive functional group (c), and the polymer (P) being obtained by polymerizing a compound (A) having a poly (perfluro alkylene ether) chain and a polymerizable unsaturated group at both ends of the chain, a polymerizable unsaturated monomer (B) having a silicone group, and a polymerizable unsaturated group (C) having the functional group (c), which are included as essential monomer components, at a specified ratio. <P>COPYRIGHT: (C)2013,JPO&INPIT |
