Abstract
The description refers to aqueous coating compositions on the basis of polyurethane dispersions and their application for coating substrates. The coating compositions mainly consist of aqueous non-reactive physically drying polyurethane dispersions which are mixed with aqueous polyvinyl alcohol solutions. The coating compositions 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 have high water vapour permeability and high abrasion resistance.
