PROBLEM TO BE SOLVED: To provide an aqueous polyurethane resin dispersion which is excellent in storage stability when mixed with an inorganic particle aqueous dispersion and can suppress an increase in viscosity when highly solidified. SOLUTION: An aqueous polyurethane resin dispersion in which an acidic group in a polyurethane resin is neutralized with an amine and dispersed in an aqueous medium, wherein the amine is at least a dialkylaminomethylol represented by the following general formula (1): An aqueous polyurethane resin dispersion characterized by containing an alkane compound, a coating composition containing the aqueous polyurethane resin dispersion, a coating agent and an ink composition, and a film obtained from the aqueous polyurethane resin dispersion . (In the formula, R 1 , R 2 and Z are as defined in the specification.) [Selection figure] None |
