RECORDING MATTER, RECORDING METHOD AND READING DEVICE FOR RECORDING MATTER

摘要

PROBLEM TO BE SOLVED: To provide a recording matter for recording and displaying an independent fluorescent pattern in accordance with a wavelength of irradiated ultraviolet ray.

SOLUTION: A recording matter 100 displaying the fluorescent pattern when irradiated with the ultraviolet ray comprises a phosphor 20 for emitting light by being irradiated with the ultraviolet ray; a support body 10 supporting the phosphor 20 by dispersing it inside thereof or laminating it on an upper face thereof; and a plurality of ultraviolet absorbing layers (30, 40) disposed to cover at least a part of the phosphor 20 and made different in ultraviolet ray absorbing wavelength with each other. The plurality of ultraviolet ray absorbing layers (30, 40) form absorbing patterns independent with each other.
