Abstract
(EN)
[Problem] The present invention addresses the problem of causing a color change in the emission color emitted from a light-emitting printed layer to be reliably viewed by only moving a region irradiated with an excitation light on a printed material. [Solution] This printed material 10 has a light-emitting printed layer 20 comprising a light-emitting body including a light-emitting body A and a light-emitting body B. The saturation time of the light-emitting body B is shorter than that of the light-emitting body A, and the afterglow time of the light-emitting body B is shorter than that of the light-emitting body A. When w is the width of the light-emitting printed layer 20, l is the length of the light-emitting printed layer 20, and a is the diameter of the irradiation region 25A of UV light emitted from an LED light source 25, the relationship w≤a≤1 is satisfied.

La présente invention aborde le problème consistant à provoquer un changement de couleur dans la couleur d'émission émise à partir d'une couche imprimée électroluminescente pour être observé de manière fiable en déplaçant uniquement une région irradiée avec une lumière d'excitation sur un matériau imprimé. La solution selon l'invention porte sur un matériau imprimé (10) qui a une couche imprimée électroluminescente (20) comprenant un corps électroluminescent comprenant un corps électroluminescent A et un corps électroluminescent B. Le temps de saturation du corps électroluminescent B est plus court que celui du corps électroluminescent A, et le temps de post-luminescence du corps électroluminescent B est plus court que celui du corps électroluminescent A. Lorsque w est la largeur de la couche imprimée électroluminescente (20), l est la longueur de la couche imprimée électroluminescente (20), et a est le diamètre de la région d'irradiation (25A) de la lumière UV émise à partir d'une source lumineuse à DEL (25), la relation w ≤ a ≤ 1 est satisfaite.

[課題]印刷物上において励起光の照射領域を移動するだけで発光印刷層から発光される発光色の色変化を確実に視認できる。 [解決手段]印刷物10は発光体Aと発光体Bとを含む発光体からなる発光印刷層20を有する。発光体Bの飽和時間は発光体Aのものより短く、発光体Bの残光時間は発光体Aのものより短い。発光印刷層20の幅をw、その長さをl、LED光源25から照射されるUV光の照射領域25Aの直径をaとしたとき、w≦a≦lとなっている。
