Abstract
A water-borne coating composition containing an ether derivative of raw cotton linters (RCL), a latex polymer, and water in which the ether derivative RCL provides improved rheological properties when compared to analogous cellulose ether compounds produced from more refined cellulose sources while not substantially degrading the coating composition's aesthetic qualities.
