摘要： The invention relates to a method for making a structure with at least a first polymer layer and a second polymer layer, each made from a polycarbonate polymer based on bisphenol A, and in between the first polymer layer and the second polymer layer an intermediate layer being arranged, comprising the following steps: a) the intermediate layer is applied at least on a partial region of the first polymer layer, b) optionally the intermediate layer is dried, c) the first polymer layer is coated on the side, on which the intermediate layer is arranged, with a liquid preparation comprising a solvent or a mixture of solvents and a polycarbonate derivative based on a geminally disubstituted dihydroxydiphenyl cycloalkane, the preparation covering the intermediate layer, d) optionally a drying step is made after step c), e) after step c) or step d), the second polymer layer is placed on the first polymer layer, covering the intermediate layer, f) the first polymer layer and the second polymer layer are laminated with each other under pressure, at a temperature from 120° C. to 230° C. and for a defined time.

摘要： The invention relates to a datasheet (1) for integrating into a preferably book-like security and/or value document. The datasheet (1) is made of at least two stacked layers (2, 3) made of an organic polymer material. A textile (5) is arranged at least in a sub-region between the layers (2, 3) and outside of the layers (2, 3) so as to form a tab (4), and the textile (5) is at least partly coated on one or both sides and/or saturated with an organic binder (6) at least in the region between the layers (2, 3) and is bonded to the two layers (2, 3) by means of the binder (6).
