The dispersion particle diameter is fine and stable, and bleed-out is suppressed, and the water dispersion of resin which is useful as a surface treating agent, an adhesive agent, or a coating material for a polyolefin base material is provided.n n n A polymer (C) formed by bonding a hydrophilic polymer (B) or an acidic group to a propylene-α-olefin copolymer (A), which is a copolymer of propylene and an α-olefin other than propylene, has a particle diameter of 0.5%. As a resin dispersion formed by dispersing in water at or below mu m, the propylene content of the copolymer (A) is 50 mol% or more and less than 100 mol%, and the weight average molecular weight Mw of the copolymer (A) is 10000 or more and molecular weight distribution. The resin dispersion whose Mw / Mn is 3.5 or less and surfactant content of a resin dispersion is 15 weight part or less with respect to 100 weight part of polymers (C), and the coating material and laminated body using this. |
