Abstract
Novel coating compositions containing modified cellulose esters are disclosed. The modified cellulose esters contain acid functionality, permitting their dispersion in aqueous systems. The modified cellulose esters are particularly useful as rheology control agents in coatings which are applied as waterborne dispersions. The novel coating compositions are used to produce coated substrates with desirable appearance characteristics.
