PCT No. PCT/AT94/00186 Sec. 371 Date Jun. 5, 1996 Sec. 102(e) Date Jun. 5, 1996 PCT Filed Dec. 5, 1994 PCT Pub. No. WO95/16004 PCT Pub. Date Jun. 15, 1995A process is disclosed for preparing water-dilutable enamel paint binders based on oligourethane-acrylate copolymers. A specific monomer mixture is polymerized in the presence of a water-insoluble oligourethane obtained by reacting an aliphatic ester diol with a diisocyanate. Water dilutability is achieved by using (meth)acrylic acid. These enamel paint binders are used in combination with cross-linking components and if required other enamel paint binders to formulate baking enamels.
