Abstract

A sandwich glass having excellent safety, durability, scuff resistance and penetration resistance is disclosed, which comprises two glass plates and a laminate interposed therebetween. This laminate consists of at least two intermediate layers composed of a crosslinking type polymer composition, and an organic resin film layer interposed between the intermediate layers.

Claims

1. A sandwich glass comprising two glass plates and a laminate interposed therebetween, said laminate consisting of (A) at least two intermediate layers each composed of, an ethylene-vinyl acetate copolymer containing an organic peroxide and (B) an organic resin film layer interposed between said intermediate layers.

2. The sandwich glass according to claim 1, wherein said glass plate is a glass for the reflection or absorption of heat radiation.

3. The sandwich glass according to claim 1, wherein said organic resin film is transparent and is wholly or partially provided with various designs.

4. The sandwich glass according to claim 1, wherein said organic resin film is wholly or partially colored for the absorption of heat radiation.

5. The sandwich glass according to claim 1, wherein a thin layer of a metal or metal oxide is deposited on the surface of said organic resin film for providing an effect on the reflection of heat radiation and a conductivity.

6. The sandwich glass according to claim 5, wherein the formation of said thin film of metal or metal oxide is carried out by vapor deposition, sputtering or ion plating.

7. The sandwich glass according to claim 5 or 6, wherein said metal or metal oxide is selected from indium oxide, chromium oxide, gold, vanadium, tin, cadmium oxide, silver, platinum, aluminum, copper, copper iodide, tin oxide, tin antimony oxide and titanium oxide.
