- 2. The coating composition of claim 1 wherein the level of acid-functional monomer in the polymer is below five percent by weight of the polymer.
- 3. A process comprising:a) forming a coating composition by admixing: 1) polymer comprising, as polymerized units, from 0.5 percent to 97 percent by weight acetoacetate-functional monomer and from 3 percent to 50 percent by weight acid-functional monomer; wherein the polymer has a glass transition temperature in the range of from −20° C. to 150° C.; 2) divalent metal ion selected from the group consisting of alkaline earth metals and mixtures thereof in the form of a metal oxide, tetra-amino metal bicarbonate complex, metal complex of an —NH— or NH2— functional compound, or a metal salt, capable of reacting with the acetoacetate-functional polymer, provided the divalent metal ion is not zinc; and 3) at least one wax emulsion selected from polyethylene, polypropylene and mixtures thereof; wherein the molar ratio of acetoacetate-functional monomer to divalent metal ion is in the range of from 20:1 to 2:1; wherein the composition is free of sulfopolyester; wherein the composition is free of amino-functional silane; and wherein the composition has a VOC level of from 0 to 5 percent by weight; b) applying said coating composition to a substrate to form a coated substrate; and c) drying said coated substrate.
- 4. The process of claim 3 wherein said coated substrate is dried under ambient conditions.
- 5. An article comprising a substrate coated with a coating composition; wherein said coating composition comprises:a) polymer comprising, as polymerized units, from 0.5 percent to 97 percent by weight acetoacetate-functional monomer and from 3 percent to 50 percent by weight acid-functional monomer; wherein the polymer has a glass transition temperature in the range of from −20° C. to 150° C.; b) divalent metal ion selected from the group consisting of alkaline earth metals and mixtures thereof in the form of a metal oxide, tetra-amino metal bicarbonate complex, metal complex of an —NH— or NH2— functional compound, or a metal salt, capable of reacting with the acetoacetate-functional polymer, provided the divalent metal ion is not zinc; and c) at least one wax emulsion selected from the polyethylene, polypropylene and mixtures thereof; wherein the molar ratio of acetoacetate-functional monomer to divalent metal ion is in the range of from 20:1 to 2:1; wherein the composition is free of sulfopolyester; wherein the composition is free of amino-functional silane; and wherein the composition has a VOC level of from 0 to 5 percent by weight.
- 6. The coated article of claim 5 wherein the substrate it a flooring substrate selected from the group consisting of resilient flooring and non-resilient flooring.
- 7. The coated article of claim 5 wherein the substrate is selected from the group consisting of wood, particle board and medium density fiber board.
