To provide a laminate excellent in weather resistance, moisture-proof property, adhesion between layers and its long-term stability, and a process for its production. A laminate comprising a substrate sheet containing a fluororesin, an adhesive layer, and a moisture-proof layer containing, as the main component, at least one inorganic compound selected from the group consisting of an inorganic oxide, an inorganic nitride and an inorganic oxynitride, laminated in this order, wherein the adhesive layer contains, as the main component, at least one metal oxide selected from the group consisting of zirconium oxide, tantalum oxide and hafnium oxide.

Laminate and process for its production

To provide an agricultural film which has high transparency and which has a coating film formed with excellent abrasion resistance (adhesion), hydrophilicity (anti-fogging, wettability and anti-fouling) and hydrophilic durability. An agricultural filmcomprising a base material filmand a porous hydrophilic coating filmformed on the base material film. The hydrophilic coating filmcontains boehmite particles, silica particles and a binder, wherein (a) the atomic ratio of Al to Si (Al/Si) is from 0.2 to 5.0, (b) the average particle diameter of the silica particles is from 5 to 50 nm, and (c) the crystallite diameter of the boehmite particles, as calculated from the diffraction peak of the (120) plane is from 20 to 50 nm. The hydrophilic coating filmis formed by applying a composition comprising boehmite particles, silica particles, a binder and water, on a surface of a base material film, followed by drying.

Agricultural film

A laminated sheet comprising a woven or nonwoven fabric comprising glass fibers fixed by a binder, and a fluororesin film laminated on each other, wherein the binder contains a copolymer (A) having repeating units (a) based on at least one fluoromonomer selected from the group consisting of tetrafluoroethylene, chlorotrifluoroethylene and hexafluoropropylene, and repeating units (a) based on at least one non-fluoromonomer selected from the group consisting of a vinyl ether, a vinyl ester, an isopropenyl ether, an isopropenyl ester, an allyl ether and an allyl ester.

Laminated sheet

To provide an enclosure structure for a building, which can maintain a high power generation efficiency without formation of irregularities on the surface of the enclosure such as a roof, nor application of an external force to solar battery modules, and which can form a lightweight enclosure capable of photovoltaic generation. An enclosure structure for a building, comprising an outer film material made of a light transmitting material and arranged on the outer surface side of the building, an inner film material arranged along inside of the outer film material, an intermediate film material disposed between the outer film material and the inner film material, an air supply means for supplying air to the space between the outer film material and the inner film material, and solar battery modulesprovided on the inner surface of the intermediate film material.

Enclosure structure for building

A film for a membrane structure, which comprises a film substrate containing a fluororesin, a photocatalyst layer and an interlayer interposed between the film substrate and the photocatalyst layer, wherein the fluororesin is at least one member selected from the group consisting of an ethylene/tetrafluoroethylene copolymer, a tetrafluoroethylene/hexafluoropropylene copolymer, a tetrafluoroethylene/perfluoro(alkyl vinyl ether) copolymer, a polyvinyl fluoride and a polyvinylidene fluoride; the interlayer contains an organic-inorganic hybrid polymer obtained by hydrolyzing/co-condensing at least one member selected from the group consisting of an organosilane, a hydrolysate of an organosilane and a condensate of an organosilane, and a silyl group-containing organic polymer; and the mass remaining ratio of the organic-inorganic hybrid polymer is from 50 to 80% at 500&#xb0; C. measured by thermogravimetric analysis.
