Abstract
A description is given of aqueous coating compounds based on polyurethane dispersions together with their use for coating substrates. The coating compounds basically consist of aqueous, non-reactive, physically drying polyurethane dispersions mixed with casein and/or casein/ caprolactam copolymers or aqueous polyvinyl alcohol solutions. The coating compounds form highly elastic and largely tear-resistant protective films on substrates such as leather, wood, textile fabric or parts of the human body. The protective films exhibit high water vapour permeability and high abrasion resistance.
