Abstract (en)
[origin: WO2017009032A1] The invention relates to an aqueous dispersion containing a hydrophilic metal oxide powder with a metal oxide and a surface modification of the metal oxide, wherein a) the metal oxide is selected from the group consisting of ΤiΟ2, ZrO2, SiO2, Al2O3, Fe2O3, Fe3O4, Sb2O3, WO3, CeO2 and mixed oxides thereof and b) the surface modification comprises b1) silicon atoms and aluminum atoms and b2) the silicon atoms are bound at least partially by means of a C-atom to a hydrocarbon group b3) the molar ratio Al/Si of the surface modification is 1 :2 - 1 :20.
