Insulative multi-pane window structure of refrigerator or freezer
First Claim
1. An insulative multi-pane window structure for a forced circulation type refrigerator or freezer, said structure being interposed between a colder inside region and a warmer outside region of the refrigerator or freezer to permit vision therebetween, said structure comprising at least a first pane having a surface exposed during use to moisture-bearing air in the warmer region and a second pane opposed to and spaced from said first pane, and an infrared reflective coating on at least one surface of the surfaces constituted by the surface of said first pane which faces said second pane, the surface of said second pane which faces said first pane, and, when an intermediate pane is present between said first pane and said second pane, the surfaces of said intermediate pane, said infrared reflective coating being a transparent, electrically conductive laminated structure composed of:
- (a) a transparent solid substrate of a film-forming synthetic resin, said substrate being attached to said one surface;
(b) a thin layer of an oxide of titanium in contact with said substrate, said layer being derived from a layer of an organic compound and containing organic residual moieties of the organic titanium compound;
(c) a thin layer of an electrically conductive metal in contact with said thin layer of an oxide of titanium; and
(d) a further thin layer of an oxide of titanium in contact with said layer of conductive metal.

Abstract
An insulative multi-pane window structure of a refrigerator or freezer, said structure being interposable between a colder inside region and a warmer outside region of the refrigerator or freezer to permit vision therebetween and including at least a first pane having a surface exposed in use to humidity-bearing air in the warmer region and a second pane opposite to and spaced apart from the first pane, at least one of the first and second panes having an infrared reflecting coating attached in a specific manner; characterized in that said infrared reflective coating is a transparent, electrically conductive laminated structure composed of
(A) a transparent solid substrate of a film-forming synthetic resin,
(B) a thin layer of an oxide of titanium in contact with the substrate, said layer being derived from a layer of an organic titanium compound and containing organic residual moieties of the organic titanium compound,
(C) a thin layer of an electrically conductive metal in contact with layer (B),
(D) a thin layer of an oxide of titanium in contact with layer (C), and
(E) optionally, a transparent top layer in contact with layer (D).

6. An insulative multi-pane window structure for a natural circulation type refrigerator or freezer, said structure being interposed between a colder inside region and a warmer outside region of the refrigerator or freezer to permit vision therebetween, said structure comprising at least a first pane having a surface exposed during use to moisture-bearing air in the warmer region and a second pane opposed to and spaced from said first pane, and an infrared reflective coating on at least the surface of said second pane which faces away from said first pane and facing the colder region, said infrared reflective coating being a transparent, electrically conductive laminated structure composed of:
-
(a) a transparent solid substrate of a film-forming synthetic resin, said substrate being attached to said surface of said second pane; (b) a thin layer of an oxide of titanium in contact with said substrate, said layer being derived from a layer of an organic compound and containing organic residual moieties of the organic titanium compound; (c) a thin layer of an electrically conductive metal in contact with said thin layer of an oxide of titanium; and (d) a further thin layer of an oxide of titanium in contact with said layer of conductive metal. - View Dependent Claims (7, 8)
