Abstract
A curable composition for coating comprising: (a) a fluorine-containing highly branched polymer obtained by polymerization of a monomer A having two or more radical polymerizable double bonds in a molecule of the monomer A and a monomer B having a fluoroalkyl group and at least one radical polymerizable double bond in a molecule of the monomer B, in the presence of a polymerization initiator C at an amount of 5% by mole to 200% by mole per the number of moles of the monomer A, (b) at least one surface modifier selected from the group consisting of a perfluoropolyether compound and a silicone compound, (c) an active energy ray-curable polyfunctional monomer, and (d) a polymerization initiator that generates radicals by irradiation with an active energy ray; a cured film obtained from the composition; and a hard coating film obtained by use of the composition.
