Abstract

This invention relates to new water-emulsifiable polyester resins, a process for their production and their use as a lacquer row material. These lacquer binders are produced by the reaction of at least one prepolymer A which contains (meth)acryloyl groups and at least one unsaturated water-emulsifiable polyester B with at least one polyisocynate C.
