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.

First claim

1 .- 15 . (canceled)

16 . A composite glass with at least one chemically tempered pane, comprising:

wherein the first pane is a chemically tempered glass pane with a thickness less than or equal to 2.1 mm;
a second pane; and an intermediate layer configured to bond the second pane to the first pane,
wherein the intermediate layer contains at least one thermoplastic bonding layer and one thermoplastic carrier layer, and
wherein the thermoplastic carrier layer has a functional coating or has functional inclusions.

17 . The composite glass according to claim 16 , wherein the thermoplastic carrier layer has a functional coating, which is an IR reflecting or absorbing coating, a UV reflecting or absorbing coating, a coloring coating, a low emissivity coating, a heatable coating, a coating with antenna function, a splinter-binding coating, or a coating for shielding against electromagnetic radiation.

18 . The composite glass according to claim 17 , wherein the functional coating contains an electrically conductive layer.

19 . The composite glass according to claim 18 , wherein the electrically conductive layer of the functional coating contains silver or a transparent conductive oxide.

20 . The composite glass according to claim 17 , wherein the functional coating has a thickness of 10 nm to 200 nm.

21 . The composite glass according to claim 16 , wherein the thermoplastic carrier layer has functional inclusions with IR absorbing, UV absorbing, or coloring properties.

22 . The composite glass according to claim 16 , wherein the thermoplastic carrier layer includes organic or inorganic ions, compounds, aggregates, molecules, crystals, pigments, or dyes.

23 . The composite glass according to claim 16 , wherein the thermoplastic carrier layer has a thickness of 5 μm to 1 mm.

24 . The composite glass according to claim 16 , wherein the thermoplastic carrier layer has a thickness of 5 μm to 500 μm.

25 . The composite glass according to claim 16 , wherein the thermoplastic carrier layer has a thickness of 10 μm to 200 μm.

26 . The composite glass according to claim 16 , wherein the thermoplastic carrier layer has a thickness of 12 μm to 75 μm.

27 . The composite glass according to claim 16 , wherein the thermoplastic carrier layer contains polyethylene terephthalate (PET), polyethylene (PE), or mixtures or copolymers or derivatives thereof.

28 . The composite glass according to claim 16 , wherein the thermoplastic bonding layer contains polyvinyl butyral (PVB), ethylene vinyl acetate (EVA), polyurethane (PU), or mixtures or copolymers or derivatives thereof; and wherein the bonding layer has a thickness of 0.2 mm to 1 mm.

29 . The composite glass according to claim 16 , wherein the first pane contains from 55 wt.-% to 72 wt.-% silicon oxide (SiO 2 ), from 5 wt.-% to 10 wt.-% aluminum oxide (Al 2 O 3 ), from 10 wt.-% to 15 wt.-% sodium oxide (Na 2 O), from 7 wt.-% to 12 wt.-% potassium oxide (K 2 O), and from 6 wt.-% to 11 wt.-% magnesium oxide (MgO).

30 . The composite glass according to claim 16 , wherein the first pane has a surface compressive stress greater than 100 MPa, and a compressive stress depth greater than 40 μm.

31 . The composite glass according to claim 16 , wherein the first pane has a surface compressive stress greater than 350 MPa, and a compressive stress depth greater than 150 μm.

32 . The composite glass according to claim 16 , wherein the first pane has a thickness of 0.3 mm to 2.1 mm.

33 . The composite glass according to claim 16 , wherein the second pane is a chemically tempered glass pane having a thickness of 0.3 mm to 2.1 mm.
