PROBLEM TO BE SOLVED: To provide a fluorine atom-containing silicone-based polymerizable resin, which can provide excellent scratch resistance to a cured coating surface of an active energy ray-curable composition by adding it to the composition, the scratch resistance being never deteriorated even when the cured coating surface is treated with a chemical agent such as strong alkali, an active energy ray-curable composition using the same, a cured material of the composition, and an article having a cured coating of the composition.SOLUTION: The fluorine atom-containing polymerizable resin is a polymer having a 4-6C fluorinated alkyl, a silicone chain, an adamantyl group and a polymerizable unsaturated group. The active energy ray-curable composition includes the resin. The cured material of the composition and the article having the cured coating of the composition are also provided. |
