Abstract
Abstract A decorative substrate consisting of a paper base sheet coated with a thermoplastic material, involving a novel technique for coating and embossing the substrate. The paper sheeting is supplied with a thermoplastic material, as by coating or extrusion. The coated sheet is heated to adequately soften the coating, such as by use of a heated cylinder, and remote heat sources such as infrared heaters. The softened sheet surface is then decorated using an embossing member, to provide a diffraction pattern or hologram. Use of an embossment pattern of lesser depth than the surface roughness of the sheet before embossing provides attractive decorative patterns.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
102 words
Decorative embossed sheeting comprising: a paper substrate; a metallized layer upon said paper substrate; and a transparent thermoplastic coating upon said metallized layer, wherein said transparent thermoplastic coating at its side facing away from the paper substrate is embossed with a diffraction or holographic pattern the depth of which is less than the surface roughness of the paper substrate before embossment, and wherein the embossed pattern was produced on the thermoplastic coating by heating the coating to a temperature above its softening point and contacting the coating with an embossing member maintained at a temperature below the softening temperature of the coating.
Claim 2
Dependent Claim
