Abstract: A composite structure is disclosed. The structure includes one or several polyurethane layers, a support layer, in particular a textile support layer, as well as an optional adhesive layer placed between these layers. The composite structure is characterized in that at least one of the polyurethane layers contains a polyurethane having the formula (I) wherein O—R1—O— is the radical of a polyole with primary and/or secondary hydroxyl functional end groups, R1 and R2 independently represent an organic radical which includes aliphatic, cyclo-aliphatic, aromatic and/or heterocyclic groups, and n is an integer number between 1 and 50,000. Also disclosed is a method of manufacturing the composite structure and its use as imitation leather.

Abstract: The invention relates to a pressure and vacuum deformable, grained bonding foil for linings of motor vehicle interiors with at least one support layer, a single or multi-layer bed of polyurethane, and also, if applicable, an adhesion facilitator layer, arranged in between, a primary layer and also additional conventional layers, whereby the layer of polyurethane has a Shore D Hardness of less than 50, specifically less than approximately 48. Subject of the invention is also a method for the manufacture of the bonding foil as well as its utilization for lining the interiors of motor vehicles. Said bonding foil demonstrates excellent manipulation properties and presents outstanding physical/mechanical properties, such as excellent breaking elongation, grain stability, scratch resistance, high resistance to wear and tear, high UV-resistance, excellent solvent resistance as well as very high thermal aging resistance.
