The incorporation of a carboxyl-modified vinyl chloride/vinyl acetate copolymer in the pigment particle containing decorative layer of a floor covering improves the cohesive strength of the pigmented decorative layer and adhesion of the decorative layer to the adjacent layers. The use of this modified vinyl copolymer as the binder in the printed or coated decorative layer imparts improved bond strength particularly with platey pigments like pearlescents and metallics or in highly filled dec- orative layers containing titanium dioxide or other pigments.
