Title:
AQUEOUS DISPERSION COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2023/190213
Kind Code:
A1
Abstract:
The present invention provides an aqueous dispersion composition which, despite being aqueous, exhibits good water resistance and exhibits high peeling strength and high adhesiveness with respect to a poorly adhesive polyolefin substrate, at a low baking temperature (80-90°C). The aqueous dispersion composition is characterized by containing: a modified polyolefin (A) which has a weight average molecular weight of 60,000 or more, as measured using GPC, and in which the degree of modification by an α,β-unsaturated carboxylic acid and/or an anhydride thereof is less than 1.0 mass%; a nitrogen-containing non-ionic emulsifier (B); and a basic substance (C). The aqueous dispersion composition is also characterized in that the Z average particle diameter of the aqueous dispersion composition is 200 nm or less.
