Person-verifying medium using a luminous body, and process for producing the same

Abstract

Provided is a person-verifying medium wherein authenticity judgment is easy and forgery or alteration is difficult. Provided is a person-verifying medium wherein there is provided, on a substrate, a luminous body in a dot pattern and being formed by a material which does not emit light under visible rays but emits light under ultraviolet rays. The luminous body layer can be formed by vapor-depositing a low-molecular-weight compound luminous body or by forming a film of a polymer compound luminous body by inkjet. Alternatively, the luminous body layer is irradiated with a laser ray so as to be partially deteriorated, thereby forming a luminous body in a dot pattern. The luminous body layer in a dot pattern is preferably provided within the area surrounded by banks. It is preferable that the banks have water repellency and the area surrounded by banks is hydrophilic. The banks preferably have a form of lattice on asymmetric matrix. There is provided a highly-reflecting metal film beneath the luminous body layer, and thereby making it possible to increase the light emission.
