Zusammenfassung:	LA INVENCION SE REFIERE A UN SUSTRATO PROVISTO SOBRE AL MENOS UNA PARTE DE UNA DE SUS CARAS DE UN REVESTIMIENTO CON PROPIEDADES FOTOCATALITICAS A BASE DE DIOXIDO DE TITANIO AL MENOS PARCIALMENTE CRISTALIZADO E INCORPORADO AL MENCIONADO REVESTIMIENTO EN PARTE EN FORMA DE PARTICULAS MAYORITARIAMENTE CRISTALIZADAS EN FORMA ANATASA. LA INVENCION SE REFIERE ASIMISMO A UN METODO DE PREPARACION DE ESTE SUSTRATO Y A LAS DISPERSIONES ORGANICAS DE PARTICULAS DE DIOXIDO DE TITANIO UTILIZADAS EN EL MENCIONADO METODO DE PREPARACION DEL SUSTRATO. PCT No. PCT/FR96/01419 Sec. 371 Date Mar. 12, 1998 Sec. 102(e) Date Mar. 12, 1998 PCT Filed Sep. 13, 1996 PCT Pub. No. WO97/10185 PCT Pub. Date Mar. 20, 1997The invention relates to a substrate provided, on at least a portion of one of its faces, with a coating with a photocatalytic property based on titanium dioxide which is at least partially crystalline and which is incorporated in the said coating partly in the form of particles predominantly crystallized in the anatase form. The invention also relates to a process for the preparation of this substrate and organic dispersions of titanium dioxide particles used in the said process for the preparation of the substrate.
