Description

  The present invention relates to a product management label and an authenticity determination method using the same. Specifically, printer consumables, electronic equipment, electrical equipment, computer products, automotive parts, pharmaceuticals, chemicals, health foods and other products and parts, luxury brand watches, clothing, bags, jewelry, sports goods, cosmetics The present invention relates to a product management label for authenticating the product as a genuine product, and also relates to a method of authenticating using the product management label.

  Conventionally, various identification media are known for preventing counterfeiting of products such as the above, and various proposals have been made by the applicant of the present application. For example, Patent Literature 1 and Patent Literature 2 generate a moire pattern by superimposing a discrimination pattern forming body as a discrimination tool on a hologram image forming body in which halftone dots or line patterns are hidden. These have simple discriminating means consisting of holograms, so that counterfeit products can be prevented from traversing, but the discriminating pattern forming body, which is a discriminating tool, is made of printed matter such as line patterns and separated from the hologram image body. It is a separate one.

  Patent Document 3 proposes an anti-counterfeit printed matter in which a heat-sensitive or pressure-sensitive coloring layer is laminated on a base material and a light-interfering reflective layer in which a pearl pigment is mixed is formed on the coloring layer. In such a conventional anti-counterfeit identification medium, information for product manufacturing management such as product and part model numbers and serial numbers, and information for authenticity determination, in other words, information for anti-counterfeiting. It is formed by a separate recording method, and there is a problem in that it is wasteful and increases costs in manufacturing and usage.

Further, Patent Document 4 proposes a thermosensitive magnetic transfer body in which a ferromagnetic film having inherent magnetic characteristics is disposed on a resin substrate as a transfer material. What is obtained by this transfer body does not have information for manufacturing management, and it is unclear whether a labeler for attaching a management label to a product can be used, and can be easily applied to the above technical field. It is not a thing.
