Abstract
A method of making a differential gloss product which comprises: forming a foamable base resinous plastisol on a substrate; gelling 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 resinous plastisol a resinous wear layer containing a polymerizable and/or cross-linkable monomeric material and a free radical polymerization catalyst; gelling the wear layer; mechanically dull mat embossing the entire surface of the wear layer at a temperature below the normal decomposition temperature of the catalyst but which is sufficient to decompose the catalyst in those portions 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 resin…
