Document Type and Number:
Japanese Patent JP6558937
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a water dispersion of a polyurethane urea-acrylic composite resin good in emulsion stability and water resistance and solvent resistance of a resulting coated film without practically using an organic solvent or a surfactant.SOLUTION: There is provided a water dispersion of a polyurethane urea-acrylic composite resin obtained by emulsion dispersing an ethylenic unsaturated group-containing compound (A) and an NCO group terminal urethane pre-polymer (X) in water, extending a chain with a polyvalent amine compound (Y) and further polymerizing an ethylenic unsaturated group, where the (A) contains a compound having 2 or more ethylenic unsaturated groups (A1) and mix ratio of (A1) to (X) is 0.3 to 7.0 [mol×average unsaturated group number in (A1)] of (A1) to 1000 [g] of (X).SELECTED DRAWING: None
