ABSTRACT:
Disclosed is a coated sheet material comprising a release medium having thereon a gluable coating for use in making a decorative heat-and-pressure consolidated laminate. The gluable coating is transferred during the consolidation step from the release medium to the back side of the laminate, and the laminate can then be glued to a reinforcing substrate with conventional glues and without sanding the back of the laminate. The transferable gluable coating comprises a linear copolymer of (A) maleic anhydride or maleic acid or maleic acid salt and (B) ethylene or a vinyl monomer having a side chain of an aliphatic group with up to four carbon atoms or an alkoxy group with up to four carbon atoms.
