<p>In the prodn. of a tin oxide pigment doped with Sb2O3 and having a white or whitish colour and a superficial electrical resistance of at most 20 ohms/sq., 1.25-10 pts. (wt.) of SbO2 are mixed with 100 pts. of SnO2 and the mixt. is calcined at 900-950 deg.C. - Also claimed are white or coloured paints contg. the obtd. pigment. - 2.5-5 Pts. Sb2O3 are pref. used per 100 pts. SnO2. The paint also contains a binder, a solvent and pref. also a non-conductive pigment, the wt. ratio of the latter to the pigment of the invention being not more than 1:1. Wt. ratio of total pigments to binder is 1.5-4.</p> |
