Abstract

L'invention se rapporte à une structure multicouche (MS) comprenant (S1) au moins une première couche de polymère (S1) comprenant ≥ 95 % en poids, de préférence ≥ 98 % en poids, de préférence ≥ 99 % en poids, par rapport au poids total de la couche de polymère (S1), d'un polymère (P1) choisi dans le groupe constitué par un polycarbonate, un co-polycarbonate ou leurs mélanges ayant une température de ramollissement Vicat ≥ 149 °C, de préférence ≥ 160 °C, de préférence encore ≥ 170 °C ; plus préférentiellement ≥ 180 °C, déterminée selon la norme ISO 306 : 2004 (50 N ; 50°/h) ; (S2) au moins une autre couche de polymère (S2) ayant une température de ramollissement Vicat < 149 °C, de préférence ≤ 140 °C, plus préférentiellement ≤ 130 °C, déterminée selon la norme ISO 306 : 2004 (50 N ; 50°/h), de préférence dans une plage allant de 120 °C à 148 °C ; (S3) éventuellement au moins une troisième couche de polymère (S3) ayant une température de ramollissement Vicat ≥ 149 °C, de préférence ≥ 160 °C, de préférence encore ≥ 170 °C ; plus préférentiellement ≥ 180 °C, déterminée selon la norme ISO 306 : 2004 (50 N ; 50°/h). L'invention se rapporte en outre à un procédé de fabrication d'une structure multicouche (MS) et à un document de sécurité comprenant une telle structure multicouche selon l'invention.
