Abstract
Process for the preparation of a coating for glass and ceramic surfaces, comprising applying a first layer of a coating composition consisting of a hydroxylated material selected from hydroxylated polyesters, polyetherpolyols, polycaprolactone-polyols and hydroxylated polyesterdiisocyanate adducts, and of a cross-linking agent; thermally cross-linking said first layer; and applying a surface layer of a coating composition consisting of a film-forming material selected from hydroxylated polyesters, optionally modified epoxy resins and acrylic resins, and of a cross-linking agent; and thermally cross-linking the resulting surface layer.
