Abstract
(DE)
Die vorliegende Erfindung betrifft Schichtverbunde umfassend wenigstens eine opake Schicht a) und wenigstens eine transparente Schicht b), wobei die Vicat-Erweichungstemperatur B/120 bestimmt gemäß ISO 306:2004 (Methode B120 50N; 120°C) der Schicht a) ≥ 156 °C, bevorzugt von ≥ 156 °C bis ≤ 250 °C, besonders bevorzugt von ≥ 156 °C bis ≤ 230 °C, ist, und wobei die Vicat-Erweichungstemperatur B/120, bestimmt gemäß ISO 306:2004 (Methode B120 50N; 120°C/h) der Schicht a) höher ist als die der Schicht b), ein Verfahrung zur Herstellung von solchen Schichtverbunden sowie Sicherheitsdokumente, vorzugsweise Identifikationsdokumente umfassend einen solchen Schichtaufbau.
(EN)
The present invention relates to layer composites comprising at least one opaque layer a) and at least one transparent layer b), wherein the Vicat softening temperature B/120 determined according to ISO 306:2004 (method B120 50N; 120°C) of layer a) is ≥ 156 °C, preferably ≥ 156 °C to ≤ 250 °C, particularly preferably from ≥ 156 °C to ≤ 230 °C, and wherein the Vicat softening temperature B/120, determined according to ISO 306:2004 (method B120 50N; 120°C/h), of layer a) is higher than that of layer b), a method for producing such layer composites and security documents, preferably identification documents, comprising such a layer structure.
