Beschreibung
Zusammenfassung:	The invention relates to a method of providing an aqueous paint dispersion comprising silanized colloidal silica particles and an acrylate-based binder wherein the weight ratio of SiO2 to acrylate-based binder on a dry basis ranges from 0.02 to 0.2, and wherein the content of SiO2, measured by XRF, in said dispersion ranges from 1.05 to 7.5 wt %, wherein silane groups present in the silanized colloidal silica particles are derived from silanes containing an epoxy group, glycidoxy group, glycidoxypropyl group, ureido-based silanes, methacrylamido silanes, mercapto silanes, and combinations thereof. The invention also relates to the use thereof.
