[Object] To provide a multilayer assembly that excels in pore properties, is flexible, and is satisfactorily handled and processed; and a method of producing the multilayer assembly. [Solving Means] A multilayer assembly includes a base and, arranged on at least one side thereof, a porous layer and has a large number of continuous micropores with an average pore diameter of 0.01 to 10 µm. The multilayer assembly suffers from no interfacial delamination between the base and the porous layer when examined in a tape peeling test according to the following procedure: Tape Peeling Test A 24-mm wide masking tape [Film Masking Tape No. 603 (#25)] supplied by Teraoka Seisakusho Co., Ltd. is applied to a surface of the porous layer of the multilayer assembly and press-bonded thereto with a roller having a diameter of 30 mm and a load of 200 gf to give a sample; and the sample is subjected to a T-peel test with a tensile tester at a peel rate of 50 mm/min.

A gas generator for air bag, comprising a gas generating agent having an automatic firing function, wherein, because the gas generating agent (9b) stored in a second combustion chamber (5b) has the automatic firing function, if a vehicle causes fire, the gas generating agent (9b) will fire by itself and, accordingly, a gas generating agent (9a) and transfer charges (16a, 16b) will cause a combustion.

A gas generating composition for use in a pretensioner, which generates less CO gases and chlorine-containing gases after combustion and is superior in thermal stability and in producing and processing, is obtained. The gas generating composition for use in a pretensioner comprises a highly thermal stabilized binder, an oxidizing agent, and, if required, a chlorine-neutralizing agent as major ingredients. The gas generating composition can improve thermal stability of a gas generating agent, can reduce the amount of CO gases, is excellent in producing and processing, and can reduce chlorine-containing gases if required.

摘要:
The present invention provides a layered product having a porous layer made mainly of a polymer on a base, and a process for producing the same; and a functional layered product wherein a pattern of a functional material, such as an conductive material, is formed onto a light-transmitting base using the layered product having the porous layer, and a process for producing the functional layered product. A layered product comprising a base and a porous layer on at least one surface of the base, wherein the porous layer is constituted of a composition containing a polymer as a main component, the porous layer has micropores having an average pore diameter of 0.01 to 10 µm, and has a porosity of 30 to 85%, the composition constituting the porous layer has a glass transition temperature of 20°C or higher, and the porous layer is a layer which is convertible to a transparent layer by a heat treatment through disappearance of the micropores. A conductive pattern is formed on the porous layer surface of the layered product, and then the resultant layered product is subjected to a heat treatment to cause the micropores in the porous layer to disappear, thereby converting the porous layer to a transparent layer.
摘要:
A gas generator for an air bag which includes a gas generating agent having an automatic igniting function is provided. Since a gas generating agent 9b stored in a second combustion chamber 5b has an automatic igniting function, the gas generating agent 9b automatically ignites in case of a vehicle fire, which is accompanied by the combustion of the gas generating agent 9a and the transfer charge 16a and 16b.
