摘要： This invention relates to improved crosslinking systems for polymeric dispersions and solutions having suitability for coatings, adhesives and use in many other applications. These systems are based upon crosslinkable polymers having a plurality of activated keto methylene groups, e.g., a beta diketone such as an acetoacetate or a keto cyano methylene functional groups and a crosslinkable component comprising an aldimine. A sufficient amount of the aldimine curing agent is used to effect reaction with the polymer containing the activated keto methylene groups and cure thereof. The improvement in the crosslinking system resides in the utilization of a monoaldimine having only one aldimine group and no other methylene reactive group as a crosslinking agent. Another improvement variation to that previously suggested comprises a redispersible polymer(s) containing activated methylene functionality and combined with the monoaldimine and the use of heterocyclic aldimine.
