Abstract
The invention relates to a laminate, comprising a plastic layer which contains a thermoplastic, which plastic layer is joined at least on one side to a substantially parallel metal skin. The invention also relates to a metal-plastic-metal laminate of this type. According to the invention, the core layer includes, in addition to the thermoplastic, a solvent and a hardener, the thermoplastic being dissolved in the solvent to make the thermoplastic processible, during production of the laminate, at a temperature lower than the glass transition temperature of the thermoplastic, and the hardener being capable of reaction with the solvent, or the core layer includes polymer particles dispersed in the thermoplastic, which polymer particles are formed from a solvent and a hardener capable of reaction with the solvent. In this way, the core layer becomes easier to work during the production of the laminate, while the laminate itself, after cold-working, is dimensionally stable at elevated temperature. The invention also relates to a process for producing a laminate of this type.
