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.
In a decorative laminate formed of a rigidity imparting substrate layer and a decorative layer formed by a decorative ink, said decorative laminate including one or more resinous layers including a curable resin that, when cured, creates reaction products that could destroy the integrity of said decorative ink by causing said decorative ink to discolor, said decorative laminate being formed by a heat and pressure laminating process, the improvement comprising a barrier layer that (i) is impermeable to said reaction products created when said curable resin is cured that could destroy the integrity of said decorative ink, (ii) is located in said decorative laminate such that said decorative layer lies on one side of said barrier layer and all resinous layers that create said reaction products when said curable resin is cured lie on the other side of said barrier layer, and (iii) forms a heat sink once the decorative laminate is used after said resin is cured.
In a process for creating a decorative laminate comprising the steps of:
