AQUEOUS POLYOLEFIN RESIN DISPERSION

摘要

An aqueous dispersion characterized in that it comprises: (A) a polyolefin terpolymer resin obtained from (a) an unsaturated carboxylic acid or anhydride thereof, (b) an ethylenic hydrocarbon, and (c) a specific compound, the proportion of (a) being 0.01 to 5 wt.%, excluding 5 wt.%, and the ratio of (b) to (c) being from 55/45 to 99/1 (wt.%); (B) a basic compound; and (C) an aqueous medium, that the polyolefin terpolymer resin (A) dispersed in the aqueous medium has a number-average particle diameter of 1 mu m or smaller, and that the dispersion contains substantially no nonvolatile aqueous-dispersion aids. Also provided are: a coated film obtained by applying this aqueous dispersion to a thermoplastic resin; and a coated metallic material obtained by applying this aqueous dispersion to a metallic material.
