Abstract
This invention relates to aqueous coating compositions containing water soluble cellulose esters which are cross-linked with a resin system in the presence of an organic sulfonic acid catalyst for the formation of a film. The cellulose esters contain a low degree of substitution performed by solvolysis of cellulose esters of higher degree of substitution in the presence of a carboxylic acid catalyst.
