Abstract

Abstract An improved process for the chemical embossing of a thermoplastic sheet comprising blending 1. A VINYL RESIN, E.G., POLYVINYLCHLORIDE, 2. A PLASTICIZER FOR THE VINYL RESIN, 3. A BLOWING AGENT WHICH DECOMPOSES WHEN HEATED AT A TEMPERATURE IN THE RANGE ABOVE THE GLASS TRANSITION TEMPERATURE OF THE PLASTICIZED VINYL RESIN AND BELOW THE DECOMPOSITION TEMPERATURE OF THE RESIN, 4. AN AMINE-FORMALDEHYDE DERIVATIVE THAT WILL UNDERGO CONDENSATION POLYMERIZATION UNDER ACIDIC CONDITIONS; AND OPTIONALLY, 5. A COMPONENT CONTAINING A PLURALITY OF GROUPINGS WHICH WILL UNDERGO CONDENSATION POLYMERIZATION WITH THE DERIVATIVE OF (4) UNDER ACIDIC CONDITIONS. Such a blended composition is formed into a sheet and to such sheet is applied, in a pre-determined pattern, a composition comprising A. A MATERIAL THAT WILL PENETRATE THE SHEET AND CAUSE CONDENSATION POLYMERIZATION OF COMPONENT (4) OR COMPONENTS (4) AND (5), AND, OPTIONALLY, B. A LIQUID THAT WILL PENETRATE THE SHEET, The foaming of the sheet and creating of the embossed effect is accomplished by causing the condensation polymerization to take place and heating the resulting sheet to a temperature sufficient to fuse the plasticized resin and decompose the blowing agent.
