Aqueous dispersion composition

Abstract

The present invention relates to an aqueous dispersion composition that is water-based yet exhibits a high level of peel strength and a high level of adhesion to a polyolefin substrate that is hard to adhere to in baking at low temperatures (80° C. to 90° C.), as well as excellent water resistance. The aqueous dispersion composition contains a modified polyolefin (A) having a weight average molecular weight of 60,000 or more as measured by GPC and having an amount of modification with an α,β-unsaturated carboxylic acid and/or an acid anhydride thereof of less than 1.0 mass %; a nitrogen-containing non-ionic emulsifier (B); and a basic substance (C), in which the aqueous dispersion composition has a Z-average particle size of 200 nm or less.
