ABSTRACT OF THE DISCLOSURE IMPROVED PIGMENTS AND THEIR MANUFACTURE Pigments for use in plastics should produce a composition containing as few nibs or aggregates as is possible and also develop as little dust as possible during handling. A new pigment has now been developed which comprises particulate titanium dioxide having an organic coating of isostearic acid and dodecyl benzene sulphonic acid. The pigment particles should be free of any inorganic coating A method of manufacture of the pigment is disclosed in which the isostearic acid and dodecyl benzene sulphonic acid are emulsified in water prior to addition of an aqueous dispersion of the pigment. Remarkably it has been discovered that after treatment the pigment does not require milling in a fluid energy mill and that separation from the supernatant liquid can be effected by decantation.
