  "abstract": "Cross-linked acrylate-acetoacetate polymers are disclosed. These polymers are prepared by the reaction of at least one polyfunctional acrylate with at least one diacetoacetate in the presence of a catalyst capable of promoting the reaction between the polyfunctional acrylate and the diacetoacetate. In a preferred embodiment, the polymers are employed to produce wear layer compositions for surface coverings.",
