Abstract
Abstract The invention provides a process for the production of surface covering materials having a textured effect which comprises the steps of (a) applying at least one resinous composition to selected areas of a substrate; (b) applying one or more overall layers of at least one foamable resinous composition over the substrate and resinous composition(s) thereon; and (c) heating to effect foaming of the foamable resinous composition(s) whereby a surface covering material having a textured effect is produced. The invention also provides a surface covering material having a textured effect which comprises a substrate or backing layer, resinous composition(s) on selected areas of the substrate or backing layer and at least one layer of a foamed resinous composition over the substrate and the resinous composition(s) thereon, the surface of the foamed resinous composition being at a lower level in areas with the said resinous composition(s) thereunder than in other areas of the surface covering material. The resinous compositions are conveniently polyvinyl chloride plastisols and the substrate may conveniently be a woven or nonwoven fabric, a preformed film or a film casting support.
