PROCESS FOR THE PREPARATION OF WATER-DILUTABLE COATING BINDERS, AND THE USE THEREOF

摘要

A process is disclosed for preparing water dilutable enamel paint binders ba sed on oligourethane-acrylate copolymers. A specific monomer mixture is polymerised in the presence of a water-insoluble oligoure thane obtained by reacting an aliphatic ester diol with a diisocyanate. Water dilutability is achieved by using (meth)acrylic acid. Th ese enamel paint binders are used in combination with cr oss- linking components and if required other enamel paint binders to formulate b aking enamels.
