Thermoplastic concentrates comprising inorganic pigments, such as titanium dioxide, treated with a dialkyl sulfosuccinate treating agent, of the formula ROOCCHSO3MCH2COOR', where R and R' are monovalent alkyl radicals containing from about 2 to about 20 carbon atoms and M is a metallic monovalent cation, are disclosed. Such treatment improves the dispersibility of the pigments in thermoplastic resins. The treatment also enables the production of thermoplastic concentrates comprising a high percentage of treated inorganic pigment dispersed in a thermoplastic resin.
