<P>PROBLEM TO BE SOLVED: To provide light-emitting printed matter in which a light-emitting image to be visually recognized while the image is irradiated with exciting light is changed completely different from a light-emitting image to be visually recognized after the irradiation of the exciting light ends. <P>SOLUTION: In the light-emitting printed matter having a printed image at least on part of a substrate, the printed image includes: a back-ground element group formed at a constant area ratio composed of a plurality of arrangements of the background elements; and an information element group composed of a plurality of arrangements of the information elements at a position not overlapped with the background elements. The background element group is divided into a first printing element group composed of a plurality of arrangements of first elements, and a second printing element group composed of a plurality of arrangements of second elements. During irradiation of the exciting light, the printed image is visually recognized, while during a first time after irradiation of the exciting light ends, only the first printing element group is visually recognized. <P>COPYRIGHT: (C)2012,JPO&INPIT |
