Abstract:
(EN) A laminate is provided with: a diffraction layer, which has light permeability and includes a diffraction part constituted from a plurality of diffraction units, the plurality of diffraction units being repeated along a direction in which the diffraction layer spreads and each diffraction unit including at least one diffraction element constituted from a reflective type diffraction grating; and an absorption layer, which has light permeability and includes a plurality of absorption parts that absorb at least part of visible light, the absorption layer facing the diffraction layer in a state in which light passes between the diffraction layer and the absorption layer. The side of the diffraction layer opposite from the side where the absorption layer is positioned is an observation side, and the surface of the diffraction layer on the opposite side from the surface facing the absorption layer is the front surface. In a plane view facing the front surface of the diffraction layer, each absorption part is superimposed on one diffraction element that is different from the diffraction element by which another absorption part is superimposed on.
(FR) L'invention concerne un stratifié qui est pourvu : d'une couche de diffraction, qui présente une perméabilité à la lumière et qui comprend une partie de diffraction constituée d'une pluralité d'unités de diffraction, la pluralité d'unités de diffraction étant répétées dans la direction dans laquelle la couche de diffraction s'étale et chaque unité de diffraction comprenant au moins un élément de diffraction constitué d'un réseau de diffraction de type réfléchissant ; d'une couche d'absorption, qui présente une perméabilité à la lumière et qui comprend une pluralité de parties d'absorption qui absorbent au moins une partie de la lumière visible, la couche d'absorption faisant face à la couche de diffraction dans un état dans lequel la lumière passe entre la couche de diffraction et la couche d'absorption. Le côté de la couche de diffraction opposé au côté où la couche d'absorption est positionnée est un côté d'observation, et la surface de la couche de diffraction sur le côté opposé à la surface faisant face à la couche d'absorption est la surface avant. Dans une vue en plan, faisant face à la surface avant de la couche de diffraction, chaque partie d'absorption est superposée sur un élément de diffraction qui est différent de l'élément de diffraction sur lequel une autre partie d'absorption est superposée.
(JA) 積層体は、光透過性を有し、複数の回折単位から構成される回折部を含む回折層であって、複数の回折単位は、回折層の広がる方向に沿って繰り返されるとともに、各回折単位が、反射型の回折格子から構成された少なくとも1つの回折要素を含む回折層と、光透過性を有し、可視光の少なくとも一部を吸収する複数の吸収部を含む吸収層であって、回折層と吸収層との間を光が透過する状態で回折層と対向する吸収層とを備える。回折層に対して、吸収層が位置する側とは反対側が観察側であり、回折層のうち、吸収層と対向する面とは反対側の面が表面であり、回折層の表面と対向する平面視において、各吸収部は、他の吸収部が重なる回折要素とは異なる1つの回折要素に重なっている。
