Patent number: 5059471Abstract: 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.Type: GrantFiled: February 13, 1989Date of Patent: October 22, 1991Assignee: Tarkett ABInventors: Michael H.

Patent number: 4420351Abstract: A laminated decorative tile particularly for flooring purposes, is made by forming a base layer of granulated cellulosic material in a matrix of fusible plastics, and placing on the base layer a thin decorative layer of cellulosic material with natural holes and recesses therein. After a film of fusible plastic has been applied on the decorative layer the laminate is hot pressed and then immediately cooled in a cold press. The tile obtained has a pleasing appearance because the granules of the base layer have been forced up, in the hot pressing operation, into the holes and recesses of the decorative layer, filling out these holes and recesses. In this embodiment the tile has a smooth wear resisting layer surface but this surface can be provided with a relief pattern such that it conforms to the structure of the decorative layer, if the tile after cooling is heated in a free state, i.e. without press plates.Type: GrantFiled: April 29, 1982Date of Patent: December 13, 1983Assignee: Tarkett ABInventors: Eduard Lussi, Ulf L.
