Title
(EN) METHOD OF APPLYING A PATTERN, AND SECURITY DEVICE FOR AN ARTICLE
(FR) PROCÉDÉ D'APPLICATION D'UN MOTIF, ET DISPOSITIF DE SÉCURITÉ POUR UN ARTICLE
Abstract
(EN) Methods of applying a pattern and security devices are disclosed. In one arrangement, a receiving member (10) having a layered structure (12) is provided. The layered structure (12) comprises a layer of phase change material (PCM, 2). The phase change material (PCM, 2)is thermally switchable between a plurality of stable states having different refractive indices relative to each other. An embossing member (5) is stamped into the receiving member (10). The embossing member (5) heats a selected portion of the layer of phase change material (PCM, 2) via contact with the receiving member (10) during the stamping. The heating thermally switches phase change material (PCM, 2) in the selected portion and thereby applies a pattern of different refractive indices to the layer of phase change material (PCM, 2).
(FR) L'invention concerne des procédés d'application d'un motif et des dispositifs de sécurité. Dans un agencement, un élément de réception (10) ayant une structure en couches (12) est fourni. La structure en couches (12) comprend une couche de matériau à changement de phase (PCM, 2). Le matériau à changement de phase (PCM, 2) est commutable thermiquement entre une pluralité d'états stables présentant des indices de réfraction différents les uns des autres. Un élément de gaufrage (5) est estampé dans l'élément de réception (10). L'élément de gaufrage (5) chauffe une partie sélectionnée de la couche de matériau à changement de phase (PCM,2) par contact avec l'élément de réception (10) pendant l'estampage. Le chauffage commute thermiquement le matériau à changement de phase (PCM, 2) dans la partie sélectionnée et applique ainsi un motif d'indices de réfraction différents à la couche de matériau à changement de phase (PCM, 2).
