摘要

A process for producing a titanium dioxide pigment, having improved dispersibility and the ability to increase the staining and toning power of pigmented vehicles, characterized in that an epoxide consisting of one or more epoxidized fatty acid esters with length chains between 1 and 18 carbons esterified with alcohols with length chains between 1 and 10 carbons, or in a product formed by condensation of bifunctional materials such as biphenols, glycols and dibasic acids with epichlorohydrin, is applied to a TiO2 pigment in a sufficient quantity to give the TiO2 pigment at least about 0.25% epoxide by weight of the finished pigment.
