Abstract

Il est prévu un produit stratifié comprenant un substrat ayant des pores à la surface de celui-ci, une couche transparente ou colorée, évitant l'absorption d'eau, contenant un composé contenant du silicium, formée sur ledit substrat, et une couche contenant un oxyde de titane dopé avec au moins un élément de métal sélectionné parmi le groupe consistant en cuivre, manganèse, nickel, cobalt, fer et zinc, formé sur ladite couche évitant l'absorption d'eau. Le produit stratifié ci-dessus peut être coloré de manière arbitraire, tout en conservant une bonne propriété hydrofuge et une bonne résistance aux taches.
