PROBLEM TO BE SOLVED: To provide a urethane (meth)acrylate that gives a cured layer excellent in low reflectance and scratch resistance, a curable composition obtained by using the urethane (meth)acrylate, and an antireflection film.SOLUTION: A fluorine-containing urethane (meth)acrylate represented by general formula (I) is provided. The curable composition contains the acrylate, and the antireflection film has a cured coating film of the curable composition. In formula (I), Rrepresents a fluorinated alkyl group in which the number of carbon atoms directly bonded to F is 3 to 6, or fluorinated alkyl groups connected by O, in which the number of carbon atoms directly bonded to F is 3 to 6 in total; Rand Reach represent H or a methyl group; A represents a trivalent connecting group of a branched alkyl group having 3 to 6 carbon atoms; and X represents O, S, or a divalent connecting group of -OS-N(R)-R-D-. |
