PROBLEM TO BE SOLVED: To incorporate applied visible information and to enhance safety against an illegal copy by corresponding color positions of two coloring matters to one of yellow, magenta or cyan of three-color displaying colors, and using organic or inorganic pigments for reflective coloring matters. SOLUTION: Information is applied by a method for bringing areas of various colors into contact by using a combination coloring matter of at least one type of a luminescent coloring matter and at least one type of reflective coloring matter. In this case, positions of the colors of the two coloring matters correspond to one of yellow, magenta or cyan of three-color displaying colors, and the reflective matter prepares a safe substrate for an illegal copy by using organic or inorganic pigment. The reflective matter is made of a plurality of coloring matters,so that its hue can be accurately brought into coincidence with a reflective spectrum containing no fluorescence of luminescent opponent. Similarly, the fluorescent coloring matters can be mixed to a mixture, and suitably constituted by a method for bringing about no absorption in a luminescent band. |
