Abstract:
(EN) [Problem] To provide a display medium that is discolored in a state of being exposed in the presence of oxygen. [Solution] This display medium has a discoloration layer on a substrate, the discoloration layer being formed with a redox dye, a food dye, a reducing sugar, an edible reduction promoter, an edible moisturizer, and an oxygen detection composition that contains an edible thickener. The oxygen detection composition that forms the discoloration layer is reversibly discolored in accordance with the presence of oxygen, so that the discoloration layer changes color upon transition from an oxygen-free state to an oxygen-present state. Therefore, when the discoloration layer is formed with a letter, a drawing pattern, a symbol or the like, information relating to a commodity constituted by the letter, drawing pattern, symbol or the like is highlighted by discoloration.
(FR) Le problème décrit par la présente invention est de fournir un support d'affichage qui est décoloré dans un état d'exposition en présence d'oxygène. La solution de l'invention porte sur un support d'affichage qui présente une couche de décoloration sur un substrat, la couche de décoloration étant formée à l'aide d'un colorant redox, d'un colorant alimentaire, d'un sucre réducteur, d'un promoteur de réduction comestible, d'un hydratant comestible et d'une composition de détection d'oxygène contenant un épaississant comestible. La composition de détection d'oxygène qui forme la couche de décoloration est décolorée de manière réversible en fonction de la présence d'oxygène, de telle sorte que la couche de décoloration change de couleur lors de la transition d'un état présentant une absence d'oxygène à un état présentant une présence d'oxygène. Par conséquent, lorsque la couche de décoloration est formée à l'aide d'une lettre, d'un motif de dessin, d'un symbole ou similaire, des informations relatives à une matière dont est constituée la lettre, le motif de dessin, le symbole ou similaire sont mises en évidence par décoloration.
(JA) 【課題】 酸素の存在下に曝された状態で変色する表示体を提供する。 【解決手段】 この表示体は、基材上に変色層を有するもので、前記変色層は、酸化還元色素と、食用色素と、還元糖と、可食性還元促進剤と、可食性保湿剤および可食性増粘剤を含有する酸素検知組成物で形成されている。 前記変色層を形成する酸素検知組成物は、酸素の有無に応じて可逆的に変色するものであるので、無酸素状態から有酸素状態に移行すると、前記変色層が変色する。 したがって、前記変色層が文字、図柄及び記号などで形成されている場合には、前記文字、図柄及び記号などで構成された商品に関する情報が、前記変色によって強調的に表示される。
