Abstract

PURPOSE:To vary the hue of the image copied on a photosensitive material having sensitivity in the visible light region significantly from the hue of the image of the original, by forming the image adjusted to have a high reflection factor on the short wavelength side or long wavelength side being low in the visibility of man, on the original. CONSTITUTION:This is to prepare an image forming body (original) having an image adjusted with coloring material to have a high reflection peak in the region of 450-650nm, having a high reflectance on the short wavelength side shorter than 450nm or on the long wavelength side longer than 650nm, of the ink for printing or developer for developing magnetic latent image. Using this original, when a copy image is made with a photosensitive material having sensitivity in the visible region, the hue of the copied image is significantly different from the hue of the original. Thus, by forming partial image of lottery ticket or the like in said image, a counterfeit made by using ordinary copying material, if fabricated, may be easily recognized.
