A process for producing a multilayer film which, even when bent, is less apt to decrease in barrier property or electrical conductivity. The process comprises forming a barrier film and a transparent conductive film on a resin film to produce a multilayer film. The barrier film is formed by a plasma enhanced CVD method which uses electric discharge between rolls. The transparent conductive film is preferably formed by physical vapor deposition. The resin film preferably is a polyester resin film or a polyolefin resin film.

An object of the invention is to provide an aluminum air battery that is capable of suppressing self-corrosion of an aluminum negative electrode, even when an alkaline aqueous solution is used as an electrolyte solution. The aluminum air battery of this invention comprises a positive electrode having a positive electrode catalyst, a negative electrode using an aluminum alloy, an air inlet, and an electrolyte solution, and further comprises an anion-exchange membrane arranged between the positive electrode and the negative electrode, in which the anion-exchange membrane separates an electrolyte solution in the side of the positive electrode from an electrolyte solution in the side of the negative electrode.

Disclosed are processes for producing polypropylene resin compositions including two or three sorts of propylene-based polymeric materials, the processes including a first step of melt-kneading at least a propylene-α-olefin block copolymer containing a polymer portion composed mainly of propylene and a propylene-α-olefin copolymer portion having a relatively high intrinsic viscosity and a second step of melt-kneading the product of the first step with a propylene-ethylene block copolymer containing a polymer portion composed mainly of propylene and a propylene-ethylene copolymer portion having a relatively low intrinsic viscosity or a polymer portion composed mainly of propylene having a relatively low intrinsic viscosity. In the composition produced by these processes, no or substantially no fish eyes develop.

Disclosed is a method for producing a propylene-based resin composition comprising: a first step of producing a first resin composition (MB) by melt-kneading a first-propylene polymer (A-I) and a fibrous inorganic filler (B) in a weight ratio of (A-I) to (B) of from 3/7 to 7/3; and a second step of producing a second resin composition by adding a second propylene polymer (A-II), a non-fibrous inorganic filler (C) and an elastomer (D) selected from the group consisting of olefin-based elastomer and vinyl aromatic compound-containing elastomer to the first resin composition (MB), followed by melt-kneading them.
