ABSTRACT:
Composite architectural panels comprising a substrate composed of a laminate of two metal sheets joined by a thermoplastic core and having a factory-applied polymeric surface coating which is not receptive to artists' materials, are prepared for use as a support or substrate for traditional artists' materials by roughening the surface using abrasive and/or chemical means. After thoroughly cleaning the prepared surface, one or more artists' materials are applied and permanently bonded to the panel surface by heating the panel substrate to a temperature which is less than the melting temperature of the thermoplastic core and maintaining the substrate at that temperature for a time that is sufficient to bond the artists' materials to the surface.
