A binder resin composition for secondary battery electrodes is described as containing a polymer (A) that has a structural unit represented by general formula (1) and a water-insoluble particulate polymer (B-1) and/or a water-soluble polymer (B-2) where (A), (B-1) and (B-2) are defined as described. A slurry for secondary battery electrodes contains the binder resin composition, an active material and a solvent. An electrode for secondary batteries is provided with a collector and an electrode layer that is arranged on the collector, where the electrode layer contains an active material and the binder resin composition. Alternatively, the electrode layer is obtained by applying the slurry for secondary battery electrodes to the collector, and drying the slurry thereon.

Disclosed is a carbon nanotube-containing composition which contains a carbon nanotube and a urethane compound obtained by a reaction between a hydroxyl group-containing (meth)acrylate and a isocyanate compound. Also disclosed is a composite having a coating film or a cured film composed of the carbon nanotube-containing composition on at least one surface of a base material. The carbon nanotube-containing composition and the composite are excellent in electrical conductivity, film-formability, moldability, and transparency without deteriorating the characteristic properties of the carbon nanotube itself.
