Abstract

Polyurethanes which can be dispersed in water without an emulsifier, obtainable by partial reaction of an isocyanate-terminated urethane prepolymer with a salt of an acid containing a hydrogen atom which is reactive towards isocyanate, and subsequently reacting the remaining isocyanate groups with a chain extender, and the use thereof in binders for coating compositions and adhesives.
