A novel aqueous polymeric formulation is disclosed. Also disclosed are methods of making the polymeric formulation, and of using the polymeric formulation to produce a crosslinked polymeric surface coating on a substrate. One embodiment of the novel polymeric formulation comprises an aqueous carrier; at least one polymeric ingredient; a non-polymeric polyfunctional amine; and base. The one polymeric ingredient has both acid-functional and acetoacetoxy-type functional pendant moieties. The non-polymeric polyfunctional amine has at least two amine-functional moieties. The amount of base contained within the formulation is effective for inhibiting gellation, which would otherwise occur as a result of crosslinking between the acetoacetoxy-type functional and amine-functional moieties. Another embodiment of the novel polymeric formulation comprises at least two polymeric ingredients, one of which has acetoacetoxy-type functional pendant moieties and the other of which has acid-functional pendant moieties.

A crosslinked polymeric surface coating produced in accordance with a method comprising the steps of: producing an aqueous evaporable polymeric formulation by admixing at least one polymeric ingredient, a non-polymeric polyfunctional amine, and base, in an evaporable aqueous carrier, wherein the polymeric ingredient has both acid-functional pendant moieties and pendant moieties having the ability to form stable enamine structures by reaction with amines and contain a divalent group of the structure [Figure] wherein R1 is either H, a C1 to C10 alkyl group or phenyl, wherein the non-polymeric polyfunctional amine has at least two amine-functional moieties and wherein the amount of base in the formulation is effective for inhibiting gellation, which would otherwise occur as a result of crosslinking between the pendant moieties having the ability to form stable enamine structures and amine-functional moieties, thereby producing a reaction mixture; holding the reaction mixture at a preselected reaction temperature for a predetermined period of time, thereby producing the aqueous evaporable polymeric formulation; applying the aqueous evaporable polymeric formulation onto a substrate; and evaporating that amount of evaporable ingredients from the substrate-applied formulation which is effective for enabling desired crosslinking to take place as between the pendant moieties having the ability to form stable enamine structures and amine-functional moieties, thereby producing the crosslinked polymeric surface coating on the substrate.
