Abstract: Disclosed is a gas barrier laminate including a gas barrier layer (II) laminated on a plastic substrate (I), wherein the plastic substrate (I) includes a metal compound in a content of 0.1 to 70% by mass and the gas barrier layer (II) includes a polycarboxylic acid.

Abstract: A semi-aromatic polyamide film including a semi-aromatic polyamide resin including a dicarboxylic acid mainly composed of terephthalic acid and a diamine mainly composed of an aliphatic diamine having 9 carbon atoms, wherein a number density of fish-eyes of 0.01 mm2 or more in size present in the film is 100/1000 cm2 or less.

Abstract: Disclosed is a binder for electrode formation, which is obtained by dispersing a polyolefin resin containing 50 to 98% by mass of an unsaturated hydrocarbon having 3 to 6 carbon atoms and 0.5 to 20% by mass of an unsaturated carboxylic acid unit in an aqueous medium together with a basic compound. This binder for electrode formation is also characterized in that the content of a nonvolatile water-compatibilizing agent is 5 parts by mass or less per 100 parts by mass of the polyolefin resin.
