Fluorine-containing active energy ray curable resin, surfactant, active energy ray curable resin composition, and cured film

Abstract

Objects are to provide a fluorine-containing active energy ray curable resin which may be suitably used as a surfactant in an aqueous active energy ray curable resin composition, to provide an active energy ray curable resin composition including the resin, and to provide a cured product obtained by curing the composition. Specifically, a fluorine-containing active energy ray curable resin is provided which includes a polymer structure (a1) derived from a radically polymerizable unsaturated monomer, a poly(perfluoroalkylene ether) chain (a2), a radically polymerizable unsaturated group (a3), and an acid group forming a neutral salt structure (a4). Also provided are a surfactant including the fluorine-containing active energy ray curable resin; an active energy ray curable resin composition including the fluorine-containing active energy ray curable resin, an active energy ray curable hydrophilic resin other than the fluorine-containing active energy ray curable resin, and water; and a cured film of the composition.
