MANUFACTURE OF THERMOPLASTIC RESIN SHEET AND PRINTING COMPOSITION FOR MANUFACTURING SAID SHEET

摘要

The present invention relates to a process for producing embossed decorative thermoplastic sheets and a printable composition for use in the process. The process comprises applying a printable composition including a blowing agent to a first gelled thermoplastic resin layer, and thereafter applying a second layer of thermoplastic resin composition having a melt viscosity differing from the first layer by at least 0.05 meter-kilograms. The composite structure is then heated for a sufficient time and temperature to gel the resin layers.
