Binder composition for non-aqueous secondary battery negative electrode, slurry composition for non-aqueous secondary battery negative electrode, negative electrode for non-aqueous secondary battery, and non-aqueous secondary battery

A binder composition for a non-aqueous secondary battery negative electrode comprising a particulate binder and water, wherein

• the particulate binder includes a polymer including an ethylenically unsaturated carboxylic acid monomer unit, an aromatic vinyl monomer unit, and an aliphatic conjugated diene monomer unit,
• proportional content of the ethylenically unsaturated carboxylic acid monomer unit when all repeating units in the polymer are taken to be 100 mass % is not less than 5.0 mass % and not more than 15.0 mass %, and
• the particulate binder has an average particle diameter Da measured by dynamic light scattering with respect to the binder composition for a non-aqueous secondary battery negative electrode when adjusted to a solid content concentration of 0.5 mass %, an average particle diameter Db measured by dynamic light scattering with respect to the binder composition for a non-aqueous secondary battery negative electrode when adjusted to a solid content concentration of 0.005 mass %, and an average particle diameter Dc measured by laser diffraction/scattering with respect to the binder composition for a non-aqueous secondary battery negative electrode that satisfy relationships in formulae (1) and (2), shown below:
