This metamerism is created by combining two or more types of pigments that have almost the same color tone in the visible light range, but with different reflectance in the infrared range, under normal conditions with the naked eye. This means that it cannot be seen from below, and can only be seen through a filter that transmits only light in the infrared region. However, although metamerism is expected to be a useful tool, there are few pigments that exhibit metamerism.

This film was exposed to ultraviolet light (wavelength > 310 nm) for 5
Immediately after the second irradiation, the absorption spectrum was measured using a spectroscopic variable needle (UV-365 Shimadzu '!A). Also,
The absorption spectrum was measured immediately after placing this film in an oven at 80° C. for 5 minutes. These results are shown in FIG. In the figure, A represents the unirradiated film, B represents the absorption spectrum immediately after irradiation with ultraviolet light, C represents the absorption spectrum immediately after heating, and D represents the absorption spectrum immediately after this operation was repeated 100 times. As is clear from the drawing, strong absorption is observed in B from 550 to 600 nm, and C and D almost match A. From this, it is possible to distinguish a commercial card printed using the ink shown in this example by changing it from colorless to colored by using an ultraviolet irradiation device, and returning it to its original colorless state by heating it. can. Since the colorless state cannot be identified with the naked eye, it is effective in preventing eastern changes.
