    Abstract: A composite material comprises a polyurethane (I), adhesively bonded to a thermoplastic substrate. The polyurethane (I) is produced by reacting (a) an isocyanate and (b) a hydroxy-functional prepolymer produced by reacting an isocyanate with a polyester polyol that is the condensation product of adipic acid and/or phthalic anhydride with diols and/or triols. Composite material comprises a polyurethane (I) adhesively bonded to a thermoplastic substrate. The polyurethane (I) is produced by reacting a mixture of (a) an isocyanate, (b) a hydroxy-functional prepolymer produced by reacting an isocyanate with a polyester polyol that has a functionality of 2-3 and a hydroxyl number of 40-400 and is the condensation product of adipic acid and/or phthalic anhydride with diols and/or triols of molecular weight 62-3000 and optionally (c) a catalyst, (d) a propellant and/or (e) additives. An independent claim is also included for a process for producing the composite material, comprising reacting components (a)-(e) in the presence of the thermoplastic substrate.
