    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 present invention relates to an organic radiation-emitting component with an active organic layer constituted to generate radiation and one or two radiation-output sides, characterised in that, on at least one radiation-output side of the component, a UV protective film is arranged and connected to the component, wherein the UV protective film contains at least one first layer (A) and a second layer (B), wherein the first layer (A) contains 0.01 to 20% by weight, with reference to the total weight of the first layer (A), of a UV absorber, and wherein the second layer (B) contains polycarbonate. Furthermore, the invention relates to the use of a component according to the invention as an organic light-emitting diode, and for lighting, especially for general lighting.
