<p><P>PROBLEM TO BE SOLVED: To obtain imitation goods preventive effect with high reliability by making the existence of imitation preventive information printed in fluorescent ink hard to be visually observed in visible rays. <P>SOLUTION: A fluorescent display body 5 is located between an outside wall 1 and an inside wall 2, and at least one of the outside wall 1 and the inside wall 2 is transparent and also has ultraviolet ray transmitting property. A fluorescent display layer 7 is formed on the fluorescent display body 5 in fluorescent ink adapted to emit fluorescent light by irradiation with an ultraviolet ray, and the presence of the fluorescent display layer 7 is hardly detected in visible rays, so that high imitation preventive effect can be obtained. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
