PROBLEM TO BE SOLVED: To form a fluorescent print image having high light emitting efficiency, excellent fluorescence and friction resistance with small influence of a substrate color, by providing thermosensitive transferable ink layers respectively containing white inorganic fluorescent pigments under a visible light ray for emitting red, green and blue fluorescences when emitting an ultraviolet ray on a base material. SOLUTION: Three types of thermosensitive transferable ink layers respectively containing white inorganic fluorescent pigments under a visible light ray for emitting red, green and blue fluorescences when emitting an ultraviolet ray are provided on a single base material or on separate base materials. Thus, a printed image of fluorescent full colors is obtained. A thermosensitive transfer ink layer is constituted of an inorganic fluorescent pigment and a resin vehicle to improve light resistance and frictional resistance of the image. Further, as the inorganic pigment, white inorganic fluorescent pigment functioned as a white pigment under the visible light ray is used, an influence of a substitute color can be reduced, absorptions of the ultraviolet ray and emitting light (fluorescence) on a substrate surface can be reduced to enhance a light emitting efficiency. |
