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： A method for issuing a virtual document by a first computer system of an issuer, includes creating the virtual document; calculating a hash value of the virtual document; sending a signed entry request including the hash value to a blockchain server; receiving the signed entry request by the blockchain server; and executing, by the blockchain server, program instructions of a program module identified by the signed entry request, wherein the execution of the program instructions includes checking the signature of the entry request, using a public cryptographic key of the issuer registered in the blockchain, and, if the signature is valid, generating an additional block of the blockchain for the issue of the virtual document, wherein the generated block includes an entry associated with the program module and including the first hash value.
