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 °C to 250 °C, said sublimate colours being supported on a suitable carrier. A natural or synthetic resin is mixed to the 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.
Procédé de décoration et/ou coloration de matériaux artificiels ou composites imitant la pierre, en forme de carreaux ou de dalles, comprenant l'application d'une ou plusieurs couleurs sublimées sur la surface à décorer et/ou colorer, cette application s'effectuant dans une plage de températures allant d'environ 50 DEG C à 250 DEG C, les couleurs sublimées étant portées par un support approprié. Une résine naturelle ou synthétique est mélangée à la composition initiale du matériau artificiel afin d'améliorer la migration des pigments de couleur à travers la surface du carreau ou de la dalle pendant le processus de sublimation. On obtient ainsi une bonne pénétration de la couleur dans la dalle, la couleur demeurant visible même après l'enlèvement de la surface polie des dalles par meulage.
