A sterically-hindered monomer is used to make a polymer which in turn is useful in coating compositions. The resulting residue of the sterically-hindered monomer is present in the polymer, as well as in a cured coating (preferably an automotive coating) produced using a coating composition having the polymer therein. The presence of the residue of the sterically-hindered monomer imparts in the cured coating a resistance to environmental etching.

The present invention is directed to an aqueous anionic acrylic dispersion produced by

Post-extended anionic acrylic dispersion

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.
