Title:
POLYURETHANE DISPERSION
Document Type and Number:
Japanese Patent JP2023135164
Kind Code:
A
Abstract:
To provide a polyurethane dispersion which is excellent in color development property and adhesion, when a fabric is printed.SOLUTION: A polyurethane dispersion is obtained by water dispersion of a polyurethane resin. The polyurethane resin is a reaction product of an isocyanate group-terminated prepolymer, monoamine, and a chain extender. The isocyanate group-terminated prepolymer is a reaction product of a polyisocyanate component, and a polyol component containing macropolyol and a hydrophilic group-containing active hydrogen compound. The acid value of the polyurethane resin is 10.5 mgKOH/g or more and 24.0 mgKOH/g or less. The total of urethane group concentration and urea group concentration of the polyurethane resin is 14 mass% or more and 22 mass% or less. The content of the monoamine in the polyurethane resin is 0.200 mmol/g or more and 0.257 mmol/g or less.SELECTED DRAWING: Figure 1
