  • Method of making embossed decorative sheets
    Patent number: 4844849
    Abstract: A method of producing embossed decorative thermoplastic sheets by forming a laminate including a printable composition, having a relatively low viscosity and containing an effective amount of a blowing agent, between thermoplastic resin sheets. The printable composition is applied in a design pattern to a gelled thermoplastic resin on a support surface. A second layer of thermoplastic resin having a melt viscosity which differs from that of the first layer is applied to the printed first layer to form a composite structure. This structure is heated to decompose the blowing agent and effect foaming in selected portions of the resin layer having are established by the printed design pattern containing the blowing agent.
