Abstract: The present invention relates to a process for production of artificial leather comprising top coat, polyurethane layer and optional substrate layer, said process comprising i) providing a release layer, ii) applying one or more than one layer of a top coat to the release layer to an overall top coat layer thickness in the range from 1 to 500 ?m, iii) applying first polyurethane system components comprising an isocyanate component (A) and a polyol component (B) to the top coat to form a first polyurethane layer, wherein the isocyanate index of the first polyurethane system components is in the range from 101 to 140, iv) optionally applying further polyurethane system components to the first polyurethane layer to form further polyurethane layers, v) optionally applying a substrate layer to the polyurethane system components, vi) curing the polyurethane system components to form a polyurethane layer, and vii) separating the release layer from the top coat, wherein the overall thickness of the first and optionally further polyurethane layers is in the range from 0.01 to 20 mm and the polyurethane system components are solvent-free. The present invention further relates to an artificial leather obtainable by such a process and to the use of the artificial leather as upper materials for footwear.
