  • Patent number: 5811484
    Abstract: A process is disclosed for preparing water-dilutable, acrylate copolymer-based lacquer binders. A polycarboxylic component is reacted with an epoxide group-containing polyhydroxylic component, and the carboxylic groups are then at least partially neutralized. As epoxide group-containing monomers for the polyhydroxylic components, glycidyl(meth)acrylate and/or glycidylallylether are used in proportions from 0.1 to 3% by weight. Associated with cross-linking components and if required with other lacquer binders, these lacquer binders are suitable for producing water-dilutable baking enamels with a low auxiliary organic solvent content.

  • Patent number: 5786435
    Abstract: The present invention relates to a low solvent content-type resin composition, a low solvent content-type coating composition containing such a resin composition as a binder, and a method for coating such a coating composition. The resin composition comprises an oligomer containing an alicyclic epoxy group in a molecule and having a number average molecular weight (Mn) of 300 to 2000, a weight average molecular weight (Mw) of 300 to 4000 and an Mw/Mn ratio of 1 to 2.5. The coating composition comprises such a resin composition and a cationic polymerization catalyst, wherein the content of an organic solvent content is 0 to 40 wt. %. Since the present composition contains a low molecular weight oligomer, the viscosity of the composition is low even though the solid content is high. Accordingly, the content of the organic solvent can be much reduced.
