ABSTRACT:
A method of preparing a pigment dispersion useful in the preparation of printing inks is provided. Said method comprises dispersing a pigment in an aqueous medium further comprised of a dispersing binder resin composition, said aqueous medium being essentially free of volatile organic solvents and said dispersing binder resin consisting essentially of the reaction product of a mixture of X equivalent percent of an acid component and Z equivalent percent of an amine component wherein the acid component is comprised of an aromatic dicarboxylic acid alone or in a mixture with an aliphatic dicarboxylic acid having from 2-25 carbon atoms, and said amine component is comprised of a mixture of a diamine and monoalkanol amine and the ratio of Z:X is less than 1 to provide a polyamide having an acid value greater than about 35. This invention also relates to printing inks comprising the pigment dispersion composition of this invention and a method of preparation thereof. This invention also relates to a method of printing a substrate comprising contacting a surface of a substrate with a composition comprising a printing ink as defined above and drying said surface to form a film of the solids of said ink in contact with said surface.
