Abstract
Abstract A method for making a sheet type decorative covering product having relief and color pattern effects in registry with each other, comprising application of a coating of liquid resin material to a base sheet, the coating containing an uncatalyzed foaming agent, after gelling of the coating and before decomposition of the foaming agent printing a decorative pattern in spaced pattern areas with a printing composition containing an agent for deactivating the catalytic action of catalysts for lowering the decomposition temperature of blowing agents, applying a transparent coating of a resin material having dispersed therein a catalyst for the blowing agent, and heating the product sufficiently to fuse the resin materials and decompose the blowing agent in areas between the printed areas.
