Lignin amine salt-based binders for water-based black ink formulations

摘要

A method of producing a lignin amine salt resin composition for black aqueous printing ink formulation having an improved storage stability wherein from 10 to 60% of the lignin amine salt resin is replaced by acrylic resin, rosin resin, or a combination thereof. The lignin amine salt formulation functions as a grinding agent for the pigment in formulating and as a binder for the pigment in the printing process.
