摘要:
There is now provided a variety of curable polyester resins that cure well with phenolic crosslinking agents. The curable polyester resins include polyester resins that have both carboxyl and hydroxyl functionalities and a high ratio of carboxyl functionalities to hydroxyl functionalities; unsaturated curable polyester having residues of an α,β-unsaturated polycarboxylic acid compound with at least one unsaturation in a position that is α,β relative to a carbonyl group and not located on an aromatic ring; and a curable polyester resin containing beta-ketoacetate moieties without vinyl unsaturation. The curable polyester resin can be dispersed in water or dissolved in a solvent and is suitable for waterborne or solventborne coating compositions. Phenolic based crosslinking coating compositions that contain these curable polyester resins cure well with phenolic resin crosslinking compounds with a wide variety of reactive curable polyester resins or other kinds of polyester resins.
