Beschreibung
Zusammenfassung:	A pearlescent pigment comprising substrate particles having an adherent layer of rutile titanium dioxide thereon is prepared by effecting the deposition of hydrous titanium dioxide on the substrate particles after contacting the particles at elevated pH with titanium tetrachloride. L'invention concerne un pigment perlé contenant des particules substrat portant une couche adhésive de dioxyde de titane rutile. Le pigment perlé selon l'invention est fabriqué par dépôt de dioxyde de titane aqueux sur les particules substrat après mise en contact des particules avec du tétrachlorure de titane dans des conditions de pH élevé.
