Abstract
A method of producing a submicron lignin-based binder resin composition for black aqueous printing ink formulation having an improved storage stability wherein from 10 to 25% of the submicron lignin binder resin is replaced by acrylic resin, rosin resin, styrene-maleic anhydride copolymer resin, or a combination thereof. The submicron lignin-based resin composition functions as a grinding agent for the pigment in formulating and as a binder for the pigment in the printing process.
