ABSTRACT:
A modified vegetable protein adhesive binder and a process for producing the same is disclosed wherein an alkaline protein dispersion is formed of a vegetable protein material and said dispersion is treated with a cationic monomer, preferably a cationic monomer selected from the group consisting of cationic epoxide monomers and cationic acrylate monomers, in an amount sufficient to modify the protein material. The modified vegetable protein adhesive binder has a greater affinity for pigments in a paper coating composition. This greater pigment affinity results in an improvement in the porosity of the final coating, thereby improving ink receptivity and printability on the coating surface.
