ABSTRACT:
The invention is pigment grinding aids for water-based inks which are produced by reacting an unsaturated fatty acid and/or resin acid with either acrylic acid, metacrylic acid, fumaric acid, or maleic anhydride to form a polycarboxylic acid anhydride. The polycarboxylic acid anhydride is reacted with an excess of polyamine to produce an amidoamide or imidoamide intermediate. This intermediate is reacted with either acrylic acid or methacrylic acid to produce the grinding aid.
