Abstract

The invention relates to a composite false-proof film which mainly comprises a substrate layer, a concealed holographic layer, a plated metal layer, and a transparent two-dimension bar code printing layer. The concealed holographic layer is arranged under the substrate layer. The plated metal layer is arranged under the concealed holographic layer. The transparent two-dimension bar code printing layer is arranged above the substrate layer and is made of transparent printing ink of organic dye. In enforcement, an adhesive layer can be additionally arranged under the plated metal layer. Therefore, the formed false-proof film is enabled to be small is area and beautiful in appearance, the transparent two-dimension bar code printing layer can be directly arranged above the laser concealed holographic layer, space is effectively utilized in a multi-layer overlaying manner, concealed holographic false-proof content is formed as a floating shadow on the false-proof film by passing through a two-dimensional bar code through light source reconstruction, and dual effects of laser concealed holographic false proof and two-dimensional bar code scanning can be achieved.

Description

technical field [0001] The invention relates to a compound anti-counterfeiting film, especially refers to the anti-counterfeiting film composed of multi-layer nesting which effectively utilizes the space, has a small area, is exquisite and beautiful, and has dual functions of hiding the holographic anti-counterfeiting floating shadow of a laser and scanning a two-dimensional barcode. Composite security code. Background technique [0002] In recent years, the combination of laser holographic anti-counterfeiting technology and printing technology has developed rapidly in the packaging and printing industry. Among them, the colorful iridescent effect of the pattern of the hologram is obvious, and it has a decorative effect and an anti-counterfeiting effect. It is widely used in high-quality trademarks, securities, Credit cards and advanced handicrafts, etc. [0003] However, with the continuous development and progress of science and technology, traditional laser holographic ...
