  • Cellulose esters moidified with anhydrides of dicarboxylic acids and their use in waterborne basecoats
    Patent number: 5384163
    Abstract: Novel coating compositions containing modified cellulose esters are disclosed. The modified cellulose esters contain acid functionality, permitting their dispersion in aqueous systems.
