Abstract of the Disclosure Coating compositions comprising a polymeric polyol with a poly- aster crosslinking agent having at least two substituted ester groups per molecule are disclosed. The substituents are selected from the class con- sisting of beta-alkoxyester groups, beta-ester groups, beta-amido groups, gamma-hydroxy groups, gamma-ester groups and delta-hydroxy groups. The compositions, when applied to a substrate and cured in the presence of a transesterification catalyst, give solvent-resistant coatings.
