Title:
AQUEOUS POLYURETHANE RESIN DISPERSION AND METHOD FOR PRODUCING SAME, PAINT, FILM ARRANGEMENT, AND STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2019/221087
Kind Code:
A1
Abstract:
Provided is an aqueous polyurethane resin dispersion in which polyurethane resin particles are dispersed in water, the aqueous polyurethane resin dispersion comprising at least 45 mass% of a nonvolatile component. The polyurethane resin particles contain a polyol component and an isocyanate component, and at least 10 mol% or more of the isocyanate component is a straight-chain aliphatic isocyanate component having 4 to 10 carbons. The polyurethane resin particles have a volume-average particle diameter of 0.05 to 5 μm.
