Abstract
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.

A laminated multilayer sheet structure comprising (A) an opaque flexible sheet layer, and (B) a flexible layer laminated on 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),
- said layer (B.sub.1) being a transparent thermic ray reflecting layer composed of (i) a layer of a metal having a thickness of about 50 to about 600 A, said metal being selected from the group consisting of gold, silver, copper, aluminum and a mixture or alloy of at least two of said metals, and (ii) a high refractive substance layer having a thickness of about 50 to about 600 A, of an oxide of titanium derived from a layer of an organic titanium compound of the formula
- Ti.sub.l O.sub.m R.sub.n
- where R is alkyl of 1-20 carbon atoms,
- l=1-30,
- m=4+3(l-1), and
- n=4+2(l-1),
- and containing the organic residual moiety of the organic titanium compound, the amount of said organic residual moiety being 0.1 to 30% by weight based on the weight of the high refractive substance layer;
- or said layer (B.sub.1) being a transparent semiconductive layer having a thickness of about 500 to about 5,000 A and being composed of a compound selected from the group consisting of indium oxide, tin oxide, cadmium oxide, antimony oxide, copper iodide, and a mixture of at least two of said compounds.
A method for heat-insulating a room, which comprises applying to the surface of a floor, wall, ceiling or partition, in the room, a laminated multilayer sheet structure comprising (A) an opaque flexible sheet layer, and (B) a flexible layer laminated on 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),
- said layer (B.sub.1) being a transparent thermic ray reflecting layer composed of (i) a layer of a metal having a thickness of about 50 to about 600 A, said metal being selected from the group consisting of gold, silver, copper, aluminum and a mixture or alloy of at least two of said metals, and (ii) a high refractive substance layer having a thickness of about 50 to about 600 A, of an oxide of titanium derived from a layer of an organic titanium compound of the formula
- Ti.sub.l O.sub.m R.sub.n
- where R is alkyl of 1-20 carbon atoms,
- l=1-30,
- m=4+3(l-1), and
- n=4+2(l-1),
- and containing the organic residual moiety of the organic titanium compound, the amount of said organic residual moiety being 0.1 to 30% by weight based on the weight of the high refractive substance layer;
- or said layer (B.sub.1) being a transparent semiconductive layer having a thickness of about 500 to about 5,000 A and being composed of a compound selected from the group consisting of indium oxide, tin oxide, cadmium oxide, antimony oxide, copper iodide, and a mixture of at least two of said compounds,
- said applying being carried out in such a manner that the layer (A) side of the sheet structure is in contact with said surface.
