Abstract This invention relates to the preparation of a novel organic thermosetting resin base decorative composition having increased permanency of adhesion and decorative properties when applied as a film or coating to a glass substrate, said composition consisting essentially of a hydroxyl functional acrylic resin, a thermosetting aminoplast resin, and an ambifunctional, epoxy reactive silane, the acrylic resin being present in an approximate stoichiometric proportion relative to the aminoplast and the silane being present in an amount sufficient to substantially improve the permanency of adhesion of the composition to a glass surface. A further advantage of this invention is that the composition can be conveniently mixed and stored in one container until used.
AS A COMPOSITION OF MATTER, A THERMOSETTING, ORGANIC RESIN BASED GLASS DECORATING COMPOSITION EXHIBITING INCREASED BRIGHTNESS, OPAGAUENESS, HARDNESS AND GLOSS, AND CAPABLE OF BEING CURED AT A HIGH ELEVATED TEMPERATURES UP TO 2000*F. WITHOUT BROWNING OR DEGRADING THEREOF, SAID COMPOSITION CONSISTING ESSENTIALLY OF AN ACRYLIC RESIN CONTAINING REACTIVE HYDROXYL GROUPS WHICH IS A COPOLYMER OF A HYDROXYL BEARING MONOMER HAVING THE FORMULA:
