ABSTRACT:
The invention relates to a multi-layer or laminated compound body, in particular vehicle tire in which at least one first layer or ply, in particular on polyurethane basis, is bonded via a coupling agent layer on polyurethane basis to a second layer or ply, in particular on polydiene basis, which layer is preferably at least essentially free of polyurethane. According to the invention, it is provided that the coupling agent layer is formed of a polyenol polyurethane whose polyenol component in a manner known per se has an OH-functionality of less than 2.1, in particular of 1.7 to 2.05, preferably of 1.9 to 2.0, at preferably terminal hydroxyl groups, and/or a corresponding polyenethiol polyurethane. The invention further relates to a process for the production of the compound body and a coupling mass for performing the process.
