Multilayer laminated material with inherently latent protection against deformation under thermal action for compensating the bimetallic effect

A solvent-free multilayer laminated material, which comprises a lower substrate layer comprising a thermoplastic polymer or a mixture of thermoplastic polymers, an intermediate layer arranged thereon and comprising a flexible material, a further fibrous intermediate layer which comprises plastic and is provided with an adhesive material, and an upper layer comprising metal, plastic, or wood,

• the flexible material of the intermediate layer comprising a mix of a crystalline polymer fraction and an elastomeric fraction, wherein the crystalline fraction is present in an amount of about 5 to 25% by weight and the elastomeric fraction is present in an amount of about 75 to 92% by weight, both calculated on total weight of the mix, having rubber-elastic properties at room temperature and having a glass transition temperature Tg of lower than 0° C.,
• wherein the lower substrate layer is an injection molded or extruded or pressed sheet having an overall thickness in the range from 1 to 20 mm throughout its entire cross-section
• wherein the fibrous intermediate layer comprises, as thermoplastic material, a polypropylene which is prepared in the presence of metallocene as a catalyst and has a melt flow index MI(2.16/230° C.) in the range from 10 to 60 g/10 min, measured according to DIN 1133 at a temperature of 230° C. and under a load of 2.16 kg.
