Abstract: This invention relates to unsaturated polyester compositions comprising cycloaliphatic diols such as 2,2,4,4-tetramethyl-1,3-cyclobutanediol (TMCD) that are curable with an isocyanate crosslinker, an amino crosslinker, or a combination thereof. The unsaturated polyester compositions provide a good balance of desirable coating properties such as solvent resistance and wedge bend resistance in metal packaging applications.

Abstract: Disclosed are novel curable acrylic modified polyesters comprising the reaction product of 2,2,4,4-tetramethyl-1,3-cyclobutanediol (TMCD) and dimethylolpropionic acid modified by an acrylic graft. The curable acrylic modified polyesters have particular utility in waterborne coating compositions. Such waterborne coating compositions provide a good balance of desirable coating properties for metal packaging applications.

Abstract: Disclosed are novel curable acrylic modified polyesters comprising the reaction product of 2,2,4,4-tetramethyl-1,3-cyclobutanediol (TMCD) modified by a polycarboxylic acid anhydride. The curable acrylic modified polyesters have particular utility for use in waterborne coating compositions containing a crosslinker. Such waterborne coating compositions provide a good balance of desirable coating properties for metal packaging applications.
