Abstract

An improved self-wound roll of a pressure sensitive adhesive coated laminate comprising a substrate which becomes dimensionally-unstable under normal processing conditions, e.g., printing, at least one layer comprising a continuous film of a normally dimensionally stable polymer adhesively fixed to one or both sides of the substrate thereby stabilizing it during processing, a transparent flexible release layer of a resin on the outwardly facing surface of the laminate, and a layer of a modified pressure sensitive adhesive on the inwardly facing surface of the substrate. The laminate can be processed without distortion, wound into rolls, unwound and applied to a surface to be decorated without delamination or shrinkage and without distortion of printed indicia, and it ultimately can be stripped without damage to the surface.
