Overhead transparencies are a substantial fraction of mixed office waste, and are currently not recyclable due, in large part, to the toner images thereon. Current transparencies are formed from a thermally-stable base sheet, such as MYLAR, with a thin toner-compatible overcoating resin. Disclosed is a coating composed of any of a class of base-soluble resins such as polyimides, polyester imides, polyimide imines, and the like resins. In a caustic recycling step, the overcoating dissolves, carrying with it the fused toner images.
