ABSTRACT:
Film suitable for thermal imaging comprising (1) a substrate formed from a flexible material, (2) a layer of thermally imageable material applied to at least one major surface of the substrate, and (3) a release coating overlying the layer of imageable material, the release coating being the hydrosilation product of (a) a polyorganohydrosiloxane, (b) an ethylenically-unsaturated perfluoropolyether monomer, and (c) an effective amount of a hydrosilation catalyst. Preferably, the film is transparent to visible light. The coating is sufficiently flexible so that the film bearing it can be imaged in commercially available infrared copying machines. Toner powder from plain paper copies will not stick to this coating when the imaging film is processed in a conventional thermal imaging apparatus.
