Beschreibung
Zusammenfassung:	The invention relates to a release coating for articles, in particular for baking moulds or other household articles or utility articles, comprising at least one base layer (G) which is fired onto the surface (O) of the article and a cover layer (D) which is fired onto the base layer. The base layer and the cover layer each have a dry film thickness of 1 to 25 [mu] m, where the base layer comprises 10 to 100 wt% of a thermoplastic having a temperature resistance of more than 200 DEG C, based on the weight of the fired base layer, and where the cover layer comprises a thermoplastic having a temperature resistance of more than 200 DEG C and optionally a silicone resin. The base layer and the cover layer do not contain perfluorinated and polyfluoroalkyl compounds. Since the cover layer has a thermoplastic content of at least 30% by weight, based on the weight of the fired cover layer, and a silicone oil of at least 2.5% by weight, based on the weight of the fired cover layer, a novel fluorine-free release coatin
