Abstract: Improved durability and sharper chemical embossing images are obtained in a thick foamed thermoplastic 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 thermoplastic 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 thermoplastic 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.

Abstract: The present invention relates to polyvinyl chloride resin particles which are colored with cationic dyestuffs, to a process of making them, and to plastisols produced therefrom. Resin particles are preferably heated in a solvent medium which preferably is water or comprises water, the solvent medium being suitable to dissolve the cationic dyestuff. The dye penetrates and dyes the particles. Particulate material can be produced having diverse characteristics.
