Title (EN) SECURITY DOCUMENT AND ELEMENT
(FR) ELEMENT ET DOCUMENT DE SECURITE
Abstract:
(EN) The present invention relates in particular to a multilayer security element (2), which comprises a transparent or translucent planar mounting (21), characterised in that one of the opposing faces of said mounting (21) is coated with the following consecutive layers: a) a layer with variable optical effect (22), i.e. which, under observation of the mounting (21), provides at least one change of appearance which is visible to the naked eye, in accordance with the observation conditions; b) a dark opaque layer (23) which has at least one slit (230); c) a semi-reflective layer (24), i.e. which is reflective when the mounting (21) is observed under reflected light, and which is transparent when the mounting is observed by transmission, said semi-reflective layer (24) being provided at least opposite one portion of said slit (230); d) a visible layer (25), i.e. which is visible under reflected light as well as by transmission, provided at least vertically in line with the one or more regions in which the semi-reflective layer (24) is provided.
(FR) La présente invention se rapporte notamment à un élément de sécurité (2) multicouche, qui comporte un support plan et transparent ou translucide (21), caractérisé par le fait que l'une des faces opposées de ce support (21) est revêtue des couches successives suivantes : a)une couche à effet optique variable (22), c'est à dire qui, sous observation du support (21), ménage au moins un changement d'aspect visuellement perceptible à l'œil nu, en fonction des conditions d'observation; b)une couche opaque sombre (23) qui présente au moins un ajour (230); c)une couche semi-réfléchissante (24), c'est à dire qui est réfléchissante lors d'une observation du support (21) en lumière réfléchie, et qui est transparente lors d'une observation du support par transmission, cette couche semi-réfléchissante (24) étant présente au moins en regard d'une partie dudit ajour (230); d)une couche visible (25), c'est à dire visible aussi bien en lumière réfléchie que par transmission, qui est présente au moins à l'aplomb de la (des) région(s) où la couche semi-réfléchissante (24) est présente.
