ABSTRACT:
A process for creating decorative laminates comprising a resin based substrate layer, a barrier layer impermeable to the reaction products produced during the curing of the substrate resin and subsequent heating of the resultant laminate, and a decorative layer formed by a decorative ink pattern is disclosed. The barrier layer, which is located between the substrate layer and the decorative layer, prevents the reaction products from reaching the decorative ink pattern when the substrate resins are cured during laminate processing, and, during subsequent heating of the final product, acts as a sink for heat stress and prevents combustible toxic gases from passing through the laminate into the surrounding environment. Thus, destructive of the decorative ink pattern during laminating processing is prevented. Further, the resulting decorative laminates have high heat release thresholds and reduce the risk of flashover in enclosed areas.
