ABSTRACT:
An improved water-based printing ink composition comprising, in aqueous medium, a colorant selected from the group consisting of a dispersed dye, a pigment, and mixtures thereof; and a water-insoluble non-sulfonated lignin acetate binder for the colorant. Also disclosed is a method of producing the improved water-based printing ink composition by reductively acetylating a non-sulfonated lignin to form a lignin acetate, drying the lignin acetate, and combining the dried lignin acetate in aqueous medium with a printing ink colorant.
