Abstract
The refinish compositions contain an acetoacetate resin based on a monomeric polyol or a hydroxy-functional oligomer of such a polyol; a blocked polyamine (polyketimine and/or polyaldimine), pigment, and alkyd polymer. The alkyd is not reactive toward the acetoacetate resin or the blocked polyamine. The refinish compositions may be prepared from an intermix system that has a plurality of color bases and an unpigmented component. Each color base includes the alkyd resin and one or more pigments dispersed with the alkyd resin. The unpigmented component includes at least one of the acetoacetate-functional resin or the blocked polyamine. A drier for the alkyd resin may be included in one of the components or in a separate, additional component.
