PHOTOCURING-TYPE HYDROPHILIC COATING AGENT, HYDROPHILIC FILM AND HYDROPHILIC COATED MATERIAL

摘要

A photocurable hydrophilic coating agent which has fingerprint-wiping properties and comprises a resin component comprising 3 to 40 mass% of (A) an acrylic resin, 0.1 to 5 mass% of (B) a polyoxyethylene -polyoxypropylene block copolymer, and 55 to 95 mass% of (C) a photopolymerizable polyfunctional compound having at least two photopolymerizable groups per molecule, wherein the acrylic resin (A) has, as the main chain, a copolymer composed of 40 to 95 mass% of a radically polymerizable monomer having a hydrophilic group and 5 to 60 mass% of a (meth)acrylic acid alkyl ester monomer.
