PROBLEM TO BE SOLVED: To provide a resin for formation of electrodes of secondary batteries which achieves good adhesion between an active material and a current collector material because the resin is hard to dissolve in an electrolytic solution, and which allows the formation of an electrode achieving good battery performance because the resin is hard to prevent an ion substance from being moved.SOLUTION: The emulsion binder for formation of electrodes of secondary batteries except nickel-hydrogen secondary batteries comprises: 0.1-5 wt.% of a carboxyl group-containing ethylene unsaturated monomer(A); 0.5-20 wt.% of an ethylene unsaturated monomer (B) having a specific structure; 0.1-10 wt.% of a nitrogen atom-containing monomer (C); and 65-99.3 wt.% of an ethylene unsaturated monomer (D) copolymerizable with them, provided that the monomers (A) to (D) are copolymerized in an aqueous medium. |
