ABSTRACT:
The flexibility of aminoplast wear layers is improved by the addition of a phyllosilicate. The concentration of the phyllosilicate is sufficiently low to not adversely affect other physical properties of the wear layer. The reduction or elimination of urethane improves stain resistance. The gloss level obtained for a given concentration of phyllosilicate depends on the particle size, and therefore type of phyllosilicate, as well as amount of phyllosilicate. A surface covering having areas of different gloss level can be obtained by printing areas forming the wear layer with compositions containing different types of phyllosilicates.
