ABSTRACT:
A pigment dispersant suitable for use in making a series of paints, the dispersant being a copolymer of defined proportions of ethylenically unsaturated monomers containing hydroxy and/or amide groups, straight or branched chain alkyl groups of from 7 to 22 carbon atoms and optionally also groupings which can promote association of the copolymer with a pigment surface. A millbase made with the aid of such a dispersant can be combined in either loading or tinting operations with a wide range of different film-forming polymers.
