A heat wave-reflective or electrically conductive laminated structure composed of (A) a shaped solid substrate, (B) a transparent thin layer having a high refractive index in contact with said substrate (A), (C) a transparent heat wave-reflective layer of an electrically conductive metal in contact with said layer (B), and (D) optionally, a transparent thin layer having a high refractive index (D') in contact with said layer (C) and a transparent top layer (D') in contact with said transparent thin layer (D'); characterized in that said layer (C) is a layer composed of Ag and Au in which the amount of Au is 3 to 30% by weight based on the total weight of Ag and Au.

Heat wave-reflective or electrically conductive laminated structure

A laminated multilayer sheet structure composed of (A) an opaque flexible sheet layer and (B) a flexible layer laminated to the surface of layer (A) and composed of a transparent thermic ray reflecting layer (B.sub.1) bonded to a transparent synthetic resin layer (B.sub.2). The sheet structure may be applied to the surface of a floor, wall, ceiling, partition or piece of furniture for indoor heat insulation.

Laminated multilayer sheet structure and its utilization

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

Transparent, electrically conductive laminated structure and process for

When a file having coated thereon an electrically conductive coating which is transparent in a highly oxidized state and non-transparent in a lowly oxidized state or in a reduced state, such as a coating of indium oxide, is heated electrically or by laser beams or oxidized and/or reduced by electrolytic reaction, images consisting of transparent and non-transparent areas are formed on the film. This can be utilized, for example, in a facsimile system.

Method for forming images by differential oxidation

When a file having coated thereon an electrically conductive coating which is transparent in a highly oxidized state and non-transparent in a lowly oxidized state or in a reduced state, such as a coating of indium oxide, is heated electrically or by laser beams or oxidized and/or reduced by electrolytic reaction, images consisting of transparent and non-transparent areas are formed on the film through an electrolytic layer on this film. This can be utilized, for example, in a facsimile system.

Method for forming images using an electrolytic layer in redox recording

An electrically insulating powdery material with a volume resistivity of at least 1 .times. 10.sup.10 ohms-cm, which consists of a calcined product of a mixture of magnesium oxide with boron oxide and if desired, at least one of titanium, iron and chromium oxides and has a special novel structure wherein a core of magnesium oxide particles is surrounded by a sheath of a double oxide of the magnesium oxide and the boron oxide and if desired, the other metal oxide. This insulating powdery material is produced by calcining the above mixture under specified calcining conditions determined by a special temperature-time relation. A thermally conducting and electrically insulating resin composition especially having superior electrical properties under high temperature-high humidity conditions can be prepared using the above powdery material as a filler.
