ABSTRACT:
Stoving enamels comprising epoxy resins and carboxyl-functional alkylidenepolyphenols in a quantity such that the carboxyl groups are present at least in equimolar quantities relative to the epoxide groups of the epoxy resins are suitable for coating the inside of metallic food containers and give, on the packaging, baked coating films which are essentially free from migratable constituents carrying epoxide groups.
