Abstract
A process for producing a decorative surface covering wherein granular dryblend is deposited on a releasable carrier and heated to form a porous cohesive layer. Settable resinous inks are then applied to selected areas of the dryblend to form a design which may extend partially or completely through the layer to the bottom surface thereof which ultimately becomes the face of the surface covering. The ink may optionally be set by heat prior to or simultaneously with the subsequent application and gelling of a resinous back coating which may be reinforced by included or attached material to form a permanent carrier. The release carrier is then removed. A multi-level wear surface is achieved on the surface covering by removing the non-ink-containing portions of the dryblend either before or after the composite structure is turned over and heat is applied to fuse the remaining resinous material.
