Abstract
Abstract An embossing machine tape is provided employing a film of a stress whitening, substantially transparent elastomer-modified methyl methacrylate polymer, normally employed in combination with a non-stress whitening, opaque, normally colored, polymer film backing. In usual applications, an adhesive coating is applied to the backing and protected by a releasable liner. The stress whitening film provides sharply delineated symbols without fracture, when embossed, and substantially free of ghosts in the usual embodiment.
