In a low temperature cure coating composition that does not catalyze the cross-linking reaction between the hydroxy-functional resin, the cross-linking agent, and the hydroxy-functional resin and the cross-linking agent contained therein, but instead differs from the hydroxy-functional resin. A storage-stable low-temperature curing coating composition comprising a catalyst that catalyzes a crosslinking reaction with a contained crosslinking agent. In addition, an aqueous basecoat containing a first hydroxy functional resin, a first crosslinker, a first catalyst, and an organic solvent; a second hydroxy functional resin, a second crosslinker, a second A low temperature cure composite coating comprising a catalyst, and a solvent-based topcoat containing water, wherein the first catalyst is transferred from the basecoat to the topcoat between the second hydroxy functional resin and the crosslinker. A composite coating in which the reaction is catalyzed and a second catalyst is transferred from the topcoat to the basecoat to catalyze the reaction between the first hydroxy functional resin and the crosslinker. |
