A concrete having a smooth surface, which is wholly or partly coated with a polymer film obtained by polymerisation under the action of radiation, where the film is itself wholly or partly coated with a thin photovoltaic film.

MAGENTA INK COMPOSITION FOR DECORATING NON-POROUS SUBSTRATES, in particular an ink composition containing an organic solvent as a carrier which is liquid at room temperature, a gold compound soluble in the liquid medium of the ink, a binder composition with submicrometric particles of a glass frit, submicrometric particles of oxides or inorganic primary materials and additives. Said ink is intended for printing by means of injection technology on non-porous surfaces in general which are subjected to a heat treatment which allows a magenta coloration to develop which is permanent and resistant to abrasion, cleaning agents and weathering.
