Abstract:
A composite glass comprises two glass and/or plastic plates and an intermediate foil arranged between the glass and/or plastic plates. The composite glass, due to the intermediate foil, is configured differently in a side-dependent manner, by appearing to a viewer more transparent from an inner side than from an outer side. The composite glass, due to the intermediate foil, appears to the viewer different in a viewing angle-dependent manner from the outer side.
