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&#xb0; C. to 230&#xb0; C. and for a defined time.

Method for producing a polycarbonate layered composite

The invention relates to the use of a preparation comprising A) 0.1 to 20 wt % of a binding agent with a polycarbonate derivative based on a geminally disubstituted dihydroxydiphenyl cycloalkane, B) 30 to 99.9 wt % of an organic solvent or of a mixture of solvents, C) 0 to 10 wt %, referred to dry mass, of a dye or of a mixture of dyes, D) 0 to 10 wt % of a functional material or of a mixture of functional materials, E) 0 to 30 wt % of additive and/or auxiliary substances, or of a mixture of such substances, the relative amounts of the components A) to E) always totaling 100 wt %, as an ink jet printing dye.

Method for the production of a polycarbonate laminate

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

Data sheet for a security and/or value document

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, between the polymer layers a component being arranged, comprising the following steps: a) the component is arranged on the first polymer layer or placed in a depression of the first polymer layer, b) the first polymer layer is coated on the side, on which or in which the component is arranged, at least in the region of the component with a liquid preparation comprising a solvent or a mixture of solvents and a polycarbonate derivative based on a geminally disubstituted dihydroxydiphenyl cycloalkane, c) optionally a drying step is made after step b), d) after step b) or step c), the second polymer layer is placed on the first polymer layer, covering the component, e) the first polymer layer and the second polymer layer are laminated with each other under pressure, at a temperature from 120&#xb0; C. to 180&#xb0; C. and for a defined time.
