Abstract
Abstract A method of and articles for decorating heat resistant surfaces such as glass or metal using a heat transfer decoration comprising in sequence a temporary carrier, a transfer lacquer layer which is removably adhered to the surface of said carrier, at least one design print layer adhered over the lacquer layer and a heat-activatible adhesive layer adhered over said design print layer wherein at least the transfer lacquer and design print layers contain cross-linkable resin means and a crosslinking agent for cross-linking the resin intralayer and interlayer to form a unified adherent decoration resistant to abrasion and chemicals. The metal or glass surface may optionally be coated with a cross-linkable primer composition prior to application of the heat transfer decoration thereto.
