    摘要: The present invention relates to a process for the preparation of an aqueous coating composition containing a carboxyl-containing epoxy resin having an acid number in the range from 5 to 200 mg of KOH/g and having an epoxide equivalent weight in the range from 1000 to 40,000, optionally crosslinking agents, organic solvents, optionally conventional assistants and additives, and optionally pigments and fillers. The organic binder solution is neutralized using a tertiary amine in the temperature range from 60.degree. C. to 120.degree. C. This is followed by dispersion in water, with the proviso that at least 95% of the epoxide groups of the epoxy resin have been reacted. The aqueous coating compositions prepared by the process are preferably used for coating cans.
