Abstract
A laminated glass comprising a first glass sheet; a first interlayer overlying the first glass sheet, wherein the first interlayer comprises a first polysilicate coating; a second glass sheet overlying the first interlayer; a second interlayer overlying the second glass sheet, wherein the second interlayer comprises a first reinforced silicone resin film having a first major surface and a second major surface, a first silicone adhesive coating lying directly on the first major surface of the film, and a second silicone adhesive coating lying directly on the second major surface of the film; and a third glass sheet overlying the second interlayer.

A laminated glass, comprising:
- a first glass sheet;
- a first interlayer overlying the first glass sheet, wherein the first interlayer comprises a first polysilicate coating;
- a second glass sheet overlying the first interlayer;
- a second interlayer overlying the second glass sheet, wherein the second interlayer comprises a first reinforced silicone resin film having a first major surface and a second major surface, a first silicone adhesive coating lying directly on the first major surface of the film, and a second silicone adhesive coating lying directly on the second major surface of the film;
- and
- a third glass sheet overlying the second interlayer;
- wherein the first polysilicate coating comprises from 50 to 85% (w/w) of at least one alkali metal polysilicate and from 15 to 50% (w/w) of water, wherein the alkali metal polysilicate has a mole ratio of silica to metal oxide of at least 1.05, and the first silicone adhesive coating and the second silicone adhesive coating each comprise a cured product of at least one silicone resin.
