<p>A protein material, particularly a vegetable protein material such as soy, can be modified to produce a product useful as an adhesive binder for pigment-containing, paper-coating compositions by treating an alkaline dispersion of the protein material with a reducing agent and then reacting the treated dispersion with a carboxylic acid anhydride. These procedures are preferably effected without any significant hydrolysis of the protein material.</p> |
