Abstract
Abstract In a method for manufacturing an embossed thermoplastic surface covering wherein a 100% reactive photopolymerizable coating is applied to the embossed thermoplastic substrate, the improvement comprising prewetting the valleys of the embossed substrate with a liquid consisting essentially of an acrylate monomer or a mixture of acrylate monomers and sufficient photoinitiator to initiate polymerization when the coated substrate is subjected to ultraviolet radiation.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
129 words
In a method for manufacturing an embossed thermoplastic surface covering having a clear, durable, tough, mar-resistant photopolymerized wear layer wherein an embossed substrate is coated by passing the substrate beneath a curtain coater which applies a 100% reactive photopolymerizable coating to the substrate, said coating being compatible and curable with acrylate monomers, and wherein the coated substrate is cured by subjecting the coated substrate to a source of ultraviolet radiation, the improvement comprising: prewetting the valleys of the embossed substrate with a liquid having a viscosity of between about 10 centipoises and 100 centipoises before curtain coating the substrate, said liquid consisting essentially of an acrylate monomer or a mixture of acrylate monomers and sufficient photoinitiator to initiate polymerization when the curtain coated substrate is subjected to ultraviolet radiation.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
27 words
The method in accordance with claim 1 in which between about 1/2 to 2 grams per square foot of said liquid is used to prewet the substrate.
