A METHOD FOR DECORATING STONE-LIKE MATERIALS AND/OR WALLS, AS WELL AS A MACHINE FOR CARRYING OUT THIS METHOD

摘要

A process for decorating and/or colouring tile- or slab-shaped stone-like artificial or composite materials comprises the application of one or more sublimate colours to the surface to be decorated and/or coloured, said application being carried out at a temperature range from about 50 .degree.C to 250 .degree.C, said sublimate colours being supported on a suitable carrier. A natural or synthetic resin is mixed to th e original composition of said artificial material in order to enhance the migration of colour pigments through the tile or slab surface during the sublimation process. Thereby a good penetration of the colour into the slab is achieved, and the colour is still visible even after having removed the polished surface of the slabs by means of grinding.
