(57) [Problem] To provide a novel aqueous dispersion suitable as a coating type antistatic agent. SOLUTION: (Meth) acrylic acid content is 17 to 30% by weight, melt flow rate at 190 ° C., 2160 g load is 10 to 2000 g / 10 min, 70 mol of carboxyl groups of ethylene / (meth) acrylic acid copolymer. % The above was neutralized with triethanolamine or diethanolamine, and the average diameter measured by a light scattering method was 1 to 5 Aqueous dispersion having a solid content of 5 nm to 40% by weight. |
