Title:
AQUEOUS POLYURETHANE RESIN DISPERSION
Document Type and Number:
Japanese Patent JP3684615
Kind Code:
B2
Abstract:
PURPOSE: To obtain an aqueous polyurethane resin dispersion excellent in storage stability and also excellent in various properties of a dried product formed therefrom.
CONSTITUTION: This aqueous polyurethane resin is an aqueous dispersion of a mixture comprising a polyurethane resin (A) containing ionic functional groups and having an ionic functional value of 0.25-1.8meq/g and a polyurethane resin (B) having an ionic functional value being 0.35meq/g or below and smaller than that of the resin A. Thus, it is possible to provide an aqueous polyurethane resin being stable and excellent in the water resistance and alkali resistance of a dried product formed therefrom.
