<p>Inorganic oxides pigments, coated with alumina are treated with water soluble hydroxy acids or salts for example sodium citrate, and with water soluble di- or polyhydric alcohols, for example pentaerythritol, or with a water soluble reaction product of excess di- or polybasic organic hydroxy acids with di- or polyhydric alcohol. Titanium dioxide pigment so treated may be used in both emulsion paint and in organic based paint systems.</p> |
