Abstract: The present invention relates to a method for the decoration of porous ceramic materials and in particular polished porcelain stoneware comprising the application of a pigment or dye suitably carried on a ceramic substrate so as to allow said pigment or dye to penetrate the surface pores of the ceramic substrate, an optional drying of the colored substrate and the subsequent application of a hardenable composition in order to fix the decoration applied to the ceramic substrate. Another option for the decoration consists in the application of a pigmented hardenable composition. The hardenable composition advantageously consists of a photocurable composition.

Abstract: The present invention relates to a method for protecting a flooring or lining material, in particular ceramic materials, from staining substances and indelible agents, by means of a surface treatment with a photopolymerizable composition and subsequent curing by means of radiation (UV-VIS). The present invention also relates to ceramic materials, in particular polished porcelain stoneware with reduced soiling and staining characteristics.
