VERFAHREN ZUR HERSTELLUNG VON LEICHT DISPERGIERBAREN, TRANSPARENTEN EISENOXIDPIGMENTEN

摘要

A process for the manufacture of easily dispersed, transparent iron oxide pigments of high tinctorial strength, in which the pigment paste, moist with water, is homogenized under the action of shear forces in the presence of at least one monohydric aliphatic or cycloaliphatic alcohol of 4 to 12 carbon atoms which is partially soluble in water and can be vaporized without decomposition, and the kneaded mixture is then dried under gentle conditions. The pigments are easily dispersed in finishes or binder solutions for printing inks. Very pure and glossy colorations of optimum transparency are obtained.
