Abstract
A synthetic leather including a microfiber nonwoven has an adhesive on one surface and a layer of open-pore polyurethane foam thereon, wherein the surface of the polyurethane foam layer facing away from the microfiber nonwoven is obtained by splitting. The synthetic leather is manufacturable by a simple method in which little waste occurs. Further processing preferably takes place by back-injection in an injection molding tool.
