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.

In general, the same pigments are employed in oil- and water-based paints, printing inks, and plastics.Pigments may be organic (i.e., contain carbon) or inorganic.Organic pigments made from natural sources have been used for centuries, but most pigments used today are either inorganic or synthetic organic ones.

Generally the same pigments are employed in water and oil based paints, printed inks and plastics. They were first extracted from clay or earth. Even though most of the pigment manufacturers use age old process of preparing pigments and then convert them into clay, modern pigments are synthesized in laboratories.

A method of salt grinding pigments wherein the material to be ground is milled with an inorganic salt, an organic conditioner, and larger particles such as balls or nails for comminuting the pigment to the desired state of subdivision and is subsequently recovered from the ground mass wherein the mass is treated after grinding with an organic liquid which is a solvent for the …
