AQUEOUS POLYURETHANE RESIN DISPERSION AND USE THEREOF
Document Type and Number:
Japanese Patent JP2017048304
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an aqueous polyurethane resin dispersion capable of forming a coating film having good distortion restorability.SOLUTION: An aqueous polyurethane resin dispersion (A) contains: (a) polycarbonate polyol which contains at least two kinds of repeating units represented by formula (1), has terminal groups having hydroxy groups derived from diol on both ends, where a ratio of OH derived from diol represented by formula (2) in diol forming the terminal group is at least 1.0%, a ratio of the diol represented by formula (2) to diol represented by formula (3) in the diol forming the terminal group is 3.5-10.5, and at least one kind in Ris a divalent linear aliphatic hydrocarbon group having 5 carbon atoms; (b) polyisocyanate; and (c) acid group-containing polyol, as constituent components. In formula (1), Ris each independently C2-C12 divalent aliphatic hydrocarbon group; and Ris C1-C9 aliphatic hydrocarbon group.SELECTED DRAWING: None
