<p>A mirror comprising a glass substrate (1), a low transmissivity reflecting (2) coating on the substrate and an opacifying layer (7) which is disposed on the glass substrate for a front surface mirror or on the reflecting coating for a back surface mirror, the opacifying layer comprising an alkyd resin based paint having an organo silane primer incorporated therein. The present invention also provides a method of producing mirrors comprising depositing onto a hot ribbon of glass during the production process a low transmissivity reflecting coating and applying an opacifying layer to the glass substrate or the reflecting coating of the mirrors so formed, the opacifying layer comprising an alkyd resin based paint having an organosilane primer incorporated therein. The present invention still further provides a paint composition for use as a mirror backing paint, the paint composition having a resin component consisting of an alkyd resin as the base resin of the composition, optionally in admixture with a melamine resin, at least one opacifier and an organo silane adhesion promotor in an amount of around 5% by weight based on the weight of the paint and the paint being substantially lead-free. <IMAGE></p> |
