DEW-8916 TENSION FLOOR COVERING HAVING ENHANCED EMBOSSING AND DURABILITY Abstract Improved durability and sharper chemical embossing images are obtained in a thick foamed thermo- plastic floor structure by the use of an unfoamed inner layer. The floor covering is formed on a release paper and includes an unfoamed thermoplastic base coat, lower foamed thermoplastic layer, an unfoamed thermo- plastic inner layer, an upper foamed thermoplastic layer and a clear coat. The enhanced chemical embossing is achieved by printing an inhibitor containing ink on the inner layer and below the upper foamed layer. Multilevel embossing is obtained by embossing both foamed thermoplastic layers or applying a growth- controlling agent to both surfaces of one foamable ther- moplastic layer. The preferred embodiment includes a pearl platelet containing layer above the upper foamed layer to give the illusion of deeper embossing. The preferred embodiment also includes a wear coat of the reaction product of an aminoplast, a urethane and a polyol.
