<p>Treatment of substrates, particularly transparent substrates, to impart an antifogging property thereto. The composition for an antifogging coating comprises from 40 to 80 mass % of at least one acrylic or methacrylic acid monomer, from 20 to 60 mass % of at least one acrylic or methacrylic acid ester monomer containing a short chain and, relative to the total mass of the above monomers, from 1 to 15 % of a crosslinking agent and from 0.1 to 5 % of a compound initiating polymerisation by the action of ultraviolet radiation. Application to the transparent products made up of a glass or polymethyl methacrylate substrate and a layer of the above composition polymerised and crosslinked by the action of ultraviolet radiation.</p> |
