Abstract

Abstract An article and method useful for providing a flexible, substantially transparent reinforcing layer for cloth material. The article has a flexible paper base, an intermediate release layer, a layer of thermosetting material coated on said release layer and an outer layer of vinyl material on the thermosetting layer. Upon application of heat to the uncoated side of the paper, the thermosetting and vinyl layers are released from the release layer and transferred as a reinforcing patch to cloth material. The process for making this article comprises applying a layer of thermosetting material to a silicone coated paper product, drying the thermosetting layer and coating the thermosetting layer with a vinyl material, and then partially curing the vinyl so that it may be later reactivated for transfer to the cloth material.
