Disclosed are an aqueous binder composition for secondary battery negative electrodes, a slurry composition for secondary battery negative electrodes that uses said binder composition, a secondary battery negative electrode, and a secondary battery, which have excellent long-term storage stability and can improve the obtainable secondary battery cycle characteristics and stability. The aqueous binder composition for secondary battery negative electrodes is characterized by containing: a binder formed from 20 to 60 wt% of an aliphatic conjugated diene monomer, 0.5 to 10 wt% of an ethylenic unsaturated carboxylic acidic monomer, and 20 to 79 wt% of another monomer that is copolymerizable with these; and an isothiazoline compound of 0.001 - 1.0 parts by weight and a chelate compound of 0.001 - 1.0 parts by weight, relative to total 100 parts by weight of said binder. |
