DIFFERENTIAL GLOSS PRODUCTS AND METHODS OF MAKING THE SAME ABSTRACT OF THE DISCLOSURE A method of making a differential gloss product which comprises forming a foamable base resinous plastisol on a substrate; gel- ling the base resinous plastisol; applying to the base resinous plastisol various printing ink compositions in a predetermined pattern, some portions of which contain a blowing inhibitor and a polymerization temperature-lowering promoter, either in the same or different portions; applying to the printed base resi- nous plastisol a resinous wear layer containing a polymerizable and/or cross-linkable monomeric material and a free radical pol- ymerization catalyst; gelling the wear layer; mechanically dull mat embossing the entire surface of the wear layer at a temper- ature below the normal decomposition temperature of the catalyst but which is sufficient to decompose the catalyst in those por- tions of the wear layer lying directly over the polymerization temperature-lowering promoter present in some portions of the printed pattern, whereby the polymerizable monomeric material polymerizes to become cross-linked in some portions of the wear layer to permanently set the dull mat embossing thereon; and heating to a temperature sufficient to blow the foamable base resinous plastisol and to cause the dull mat embossing to flow into a smooth glossy surface in those other portions where the polymerizable monomeric material is not cross-linked and to de- compose the catalyst in such other portions to bring about a cross-linking of the polymerizable monomeric material therein to permanently set the smooth, glossy surface of the wear layer in such other portions, whereby the wear is substantially completely
