Abstract (en)

[origin: WO2020048638A1] The invention relates to a composite glass (1) comprising two glass and/or plastic panes (11, 13), as well as an intermediate film (20; 30; 40) arranged between the glass and/or plastic panes. ViaDue to the intermediate film (20; 30; 40), the composite glass (1) is designed to be different depending on the side, in that it appears more transparent for a viewer from an inner side (I) than from an outer side (A). In this case, depending on the viewing angle, the composite glass (1) appears different for the viewer from the outer side (A) due to the intermediate film (20; 30; 40).
