An invention refers to materials being used for establishment of the authenticity of documents, bank notes, valuable documents, excises and other things particularly to hot stamping laminating film which transfers polarized covert and/or visible holographic images on the protected objects.The main task of the present invention is to develop a film which provides high technological effectiveness and production of security labels contained the covert and/or holographic images, and also to develop a method of its production.The suggested laminating film for applying security information by the method of hot stamping consists of:support film with antiadhesive layer;isotropic transparent high-temperature information layer on the basis of polymer which is applied from the side of antiadhesive layer. Degree of crystallinity of polymer is about 30 % to apply the polarized covert and, if necessary, holographic images;reflecting layer is to apply the holographic and, if necessary, polarized covert images and thermosetting adhesive layer.One more object of the invention is the method of production of hot stamping laminating film. This method is based on applying the isotropic transparent high-temperature information layer to the support film with the antiadhesive layer, and also based on the production of polarized covert images and, if necessary, reflecting layer or transparent reflecting layer and holographic images with subsequent applying of thermosetting adhesive layer. |
