Abstract
A tile composition having a unique appearance created by the use of inlaid particles over an embossed and printed pattern is disclosed. In preparing the tile product, a first layer of UV curable coating is applied over the entire upper surface of a tile base. An excess of particles or chips is then sprinkled onto the surface of the first coating layer and the non-adhering particles are removed. The first layer is subjected to curing and a second layer of UV curable coating is then applied over the particles and the first layer followed by a second curing step. In one embodiment, the second coating is obtained by a combination of coating methods, including one or more direct roll coating steps followed by a curtain coating step. The particles or chips should preferably include chips of three types: (a) pigmented base color chips of which about 77 to 100 weight percent are of a U.S. mesh size in the range of between 60 and 200; (b) clear chips of which about 77 to 100 weight percent are of a U.S. mesh size in the range of between 60 and 200; and (c) accent color chips of which about 90 to 100 weight percent are of a U.S. mesh size in the range of between 40 and 200.
