Abstract
The present invention relates to an article comprising expanded thermoplastic polyurethane as a substrate and a specific polyurethane urea coating on said substrate, as well as footwear, a process for producing the article and a use of a polyurethane urea dispersion/solution. It has been found that a polyurethane urea coating comprising polycarbonate structural units strongly binds to expanded TPU substrates and maintains the intrinsic properties of the expanded TPU.
