Abstract: A dispersible TiO2 pigment carries on its surface the reaction product of trimethylol propane and an alkylene oxide. The TiO2 may be pretreated by precipitating Al(OH)3, SiO2 or TiO2 thereon. The TiO2 pigment may contain 0.05-2% of the surface active agent. The alkylene oxide may be ethylene or propylene oxide. The polyol may be treated with 1-10 moles of the alkylene oxide per mole of the polyol. The surface active product may be added to the pigment undiluted or dissolved or suspended in H2O or an organic liquid.
