摘要：
The present disclosure relates to a pigment dispersion comprising silane-modified colloidal silica particles, an organic and/or inorganic pigment, a water-soluble thickening polymer in an amount of 0.1 wt. %, and water. The pigment dispersion is useful for tinting paint compositions, and exhibits excellent storage stability and washout resistance of the resulting coating. Another aspect of the present disclosure relates to a method for tinting a paint composition.
