(EN) INFORMATION RECORDING BODY AND INDIVIDUAL CERTIFYING BODY
(FR) CORPS D'ENREGISTREMENT D'INFORMATIONS ET CORPS DE CERTIFICATION INDIVIDUEL
(JA) 情報記録体、および、個人証明体
要約
(EN)
In this individual certifying body, a relief layer and a metal layer constitute an optical security patch that includes a first part including an alteration section and a part of the relief layer overlapping the alteration section as viewed from the thickness direction of a recording layer, and a second part including a non-alteration section and a part of the relief layer overlapping the non-alteration section as viewed from the thickness direction. When seen from the thickness direction, light incident on the first part is transmitted through the first part, and the second part absorbs light incident on the second part and thus hides a recording section. When seen from a direction crossing the thickness direction, light incident on the optical security patch is emitted as diffracted light through the first part and the second part.
(FR)
Dans le corps de certification individuel selon la présente invention, une couche en relief et une couche métallique constituent un correctif de sécurité optique qui comprend une première partie comprenant une section de modification et une partie de la couche en relief chevauchant la section de modification telle qu'observée dans la direction de l'épaisseur d'une couche d'enregistrement, et une seconde partie comprenant une section de non-modification et une partie de la couche en relief chevauchant la section de non-modification telle qu'observée dans la direction de l'épaisseur. Vue dans la direction de l'épaisseur, la lumière incidente sur la première partie est transmise à travers la première partie, et la seconde partie absorbe la lumière incidente sur la seconde partie et dissimule ainsi une section d'enregistrement. Vue dans une direction croisant la direction de l'épaisseur, la lumière incidente sur le correctif de sécurité optique est émise sous la forme d'une lumière diffractée à travers la première partie et la seconde partie.

個人証明体において、レリーフ層および金属層が、変質区域と、記録層の厚さ方向から見て変質区域と重なるレリーフ層の一部とを含む第1部分と、非変質区域と、厚さ方向から見て非変質区域と重なるレリーフ層の一部とを含む第2部分とを含む光学セキュリティパッチを構成する。厚さ方向から見たときに、第1部分が第1部分に入射した光を透過するとともに、第2部分が第2部分に入射した光を吸収することによって記録区域を隠蔽し、かつ、厚さ方向と交差する方向から見たときに、光学セキュリティパッチに入射する光を、第1部分と第2部分とが回折光として射出する。
