Abstract

An anti-fogging coating comprises from 40 to 80% by weight of at least one acrylic or methacrylic acid monomer, from 20 to 60% by weight of at least one short chain acrylic or methacrylic acid ester monomer and, in relation to the total weight of the preceding monomers, from 1 to 15% of a crosslinking agent and from 0.1 to 5% of a polymerization initiator compound using the action of ultraviolet radiation. Transparent products formed from a glass or poly(methyl methacrylate) support and a layer of the preceding composition, polymerized and crosslinked by the action of ultraviolet radiation, exhibit good anti-fogging and mechanical resistance properties.
