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.

A method of making decorative laminated products, such as tiles, panels or webs, which comprises the steps of granulating a cellulosic material, mixing the granulate with a fusible plastics and making a mat therefrom, cutting from a cellulosic material thin slices which in the state obtained with the through holes and recesses therein are placed on the mat thus made, applying a film of fusible plastics onthe thin slices of cellulosic material, and compressing the laminate thus obtained under supply of heat for melting the plastics and urging the material of the mat into the holes and recesses of the slice, and then cooling the compressed tile. A method as claimed in claim 1 including the further step of subjecting the tile after cooling to free heating and cooling for relief formation of the plastics film.
