<p><P>PROBLEM TO BE SOLVED: To obtain a multicolored luminescent mixture that is obtained by mixing a plurality of ultraviolet excited pigments or visible light luminescent dyes having different excitation properties and luminescent wavelengths corresponding to ultraviolet radiation wavelengths and continuously changes luminescence according to irradiation wavelength of an ultraviolet range, a multicolored luminescent ink composition and an image formation product. <P>SOLUTION: The multicolored luminescent mixture is obtained by mixing at least three illuminants selected from illuminants in which a first illuminant, a second illuminant or a third illuminant which is luminescent by ultraviolet irradiation is selected from illuminants having main wavelengths in any of an R area, a G area or a B area of an RGB color display area and the illuminants luminescent in an R area, a G area and a B area selected from a first luminescent group, a second luminescent group and a third luminescent group in which the first luminescent group is at least one illuminant that is luminescent in an R area, the second luminescent group is at least one illuminant that is luminescent in a G area and the third luminescent group is at least one illuminant that is luminescent in a B area. The image formation product is provided. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
