PROBLEM TO BE SOLVED: To provide a method of manufacturing a genuineness and spuriousness discrimination label in which a variation in color is visually recognized only when a genuineness and spuriousness discrimination is made by making a surface layer have a different color tone from a luminous body and applying a special print processing thereto and which therefore is difficult to be imitated and has easiness of the discrimination. SOLUTION: A special luminous body whose stimulating reaction is further increased by adjusting the stimulation wavelength of the luminous body is produced, and carefully selected transparent resin with high light transmissivity and only an added agent and an additive which are at least needed for reaction are kneaded to obtain ink A having high luminance and high reactivity. The ink A is applied to a base material by a silk screen printing technique to form a luminous layer (1). When white ink etc., is used to whiten the surface layer, and laminated on the luminous body layer, a stimulation spectrum is blocked by the white (ink) layer and the luminous body is stimulated to barely have low luminous luminance, so that easiness of instantaneous discrimination is lost. In the present invention, the printing technique is used to provide a color ink layer (2) as a top layer to shield the luminous layer (1). COPYRIGHT: (C)2005,JPO&NCIPI
