To provide an electrically conductive film for electric collectors, good in balance between electrical conductivity and mechanical properties and improved in water vapor permeability resistance as well, to provide a resin composition for preparing the film, and to provide a coating using the composition.
The resin composition for electrically conductive films used as an electric collector for an electrical double layer capacitor using an aqueous electrolyte comprises (1) an aromatic vinyl-conjugated diene block copolymer hydrogenated product with the ratio for aromatic vinyl-derived polymerization unit content/conjugated diene's 1,4-linkage polymerization unit-derived unit content/conjugated diene's 1,2-linkage polymerization unit-derived unit or 3,4-linkage polymerization unit-derived unit content being (10-40):(15-45):(30-65) and/or a product equivalent thereto and (2) an electrically conductive compound. The coating and the film each using this composition are also provided respectively.
