Abstract
Abstract Transparent, non-iridescent, infrared-reflecting glass window structures which are haze-free are provided herein. These structures comprise a glass sheet, an infrared-reflecting tin oxide coating on one major surface of the sheet, and an iridescence-reducing tin oxide coating on the opposed major surface of the sheet. The iridescence-reducing tin oxide coating is particularly characterized by being haze-free by virtue of its being made by contacting said sheet with monophenyltin trichloride in an oxygen-containing atmosphere.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
71 words
In a transparent, non-iridescent, infrared-reflecting glass window structure comprising a glass sheet, an infrared-reflecting tin oxide coating on one major surface of the sheet, and an iridescence-reducing tin oxide coating on the opposed surface of the sheet, the improvement characterized by: said iridescence-reducing tin oxide coating being haze-free and made by contacting said sheet at a temperature of about 450° to 650° C. with monophenyltin trichloride vapor in an oxygen-containing atmosphere.
Claim 2
Dependent Claim
71 words
In a transparent, non-iridescent, infrared-reflecting glass window structure comprising a glass sheet, an infrared-reflecting tin oxide coating on one major surface of the sheet, and an iridescence-reducing tin oxide coating on the opposed surface of the sheet, the improvement characterized by: said iridescence-reducing tin oxide coating being haze-free and made by contacting said sheet at a temperature of about 450° to 650° C. with monophenyltin trichloride vapor in an oxygen-containing atmosphere.
Claim 3
Dependent Claim
41 words
A glass window structure according to claim 1 wherein said infrared-reflecting layer comprises an undercoat, haze-free tin oxide layer made from monophenyltin trichloride, and an overcoat infrared-reflecting tin oxide layer, said overcoat layer assuming the haze-free characteristic of the undercoat layer.
Claim 4
Dependent Claim
37 words
A double-glazed glass window structure comprising at least two of said transparent, non-iridescent, infrared-reflecting glass window structures according to claim 1 assembled with the surfaces of the infrared-reflecting and the iridescence-reducing tin oxide layers facing each other.
Claim 5
Dependent Claim
49 words
A double-glazed glass window structure comprising at least two of said transparent, non-iridescent, infrared-reflecting glass window structures according to claim 2 wherein. Said glazing having a transparent, infrared reflecting layer is on the interior surface thereof, and said iridescent-reducing layer is on the interior surface of the other glazing.
