Epoxy resin containing acetoacetic groups |
摘要 |
An epoxy resin containing acetoacetic ester groups in which at least a part of the acetoacetic ester groups is enolized by atoms of at least one metal from groups I to VI or Ia to Viiia of the Periodic Table according to Meyer and Mendelejeff which metal atoms are partially bound to the enolic oxygen of the acetoacetic ester group in the form of a chelate. A process for preparing said resins wherein an epoxy resin product containing acetoacetic ester groups is further reacted in the presence of a solvent (a) first with an alkali metal alcoholate and subsequently with at least one salt of at least one chelate-forming metal; or (b) with at least one chelate-forming metal in the presence of a tertiary amine or (c) for the preparation of an epoxy resin containing chemically bound atoms of at least one metal partially bound as a chelate an epoxy resin containing acetoacetic ester groups is further reacted in the presence of a solvent with an alcoholate of at least one chelate-forming metal.
