Antiffoging composition, product coated with this composition and process for preparing this product.

摘要

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.
