Abstract
A paper coating composition comprising a paper coating pigment and a protein adhesive. The protein adhesive contains a protein material and a dispersing agent, in an amount effective to adjust the pH of an aqueous solution containing the paper coating composition sufficiently to substantially solubilize the protein material, comprising a basic reagent containing a divalent cation and a cation binding agent. The cation binding agent is present in an amount effective to inhibit divalent cation induced gel formation and pigment flocculation.
