ABSTRACT:
A heat and pressure consolidated decorative laminate having at least one core sheet in which is impregnated a vinyl ester resin. The resin is preferably derived form an epoxide terminated resin and an ethylenically unsaturated carboxylic acid. A particularly preferred epoxide terminated resin is the reaction product of bisphenol A and epichlorohydrin. Particularly preferred as the ethylenically unsaturated carboxylic acid are acrylic and methacrylic acid. The color of the core sheet(s) of the decorative laminates of this invention matches that of the face and optional back sheets. The laminates exhibit high heat resistance, flexibility, and good resistance to cracking and tearing.
