Abstract

A laminated glass comprising at least one chemically tempered pane is described. The chemically tempered pane comprises a first pane and a second pane, which are connected to each other by means of an intermediate layer. The first pane is a chemically tempered glass pane having a thickness less than or equal to 2.1 mm, wherein the intermediate layer contains at least one thermoplastic connection layer and a thermoplastic carrier layer, and the carrier layer has a functional coating or functional inclusions.
