At least a polyurethane resin obtained by reacting a high molecular weight polyol having a number average molecular weight of 500 or more, an acidic group-containing polyol, and a polyisocyanate is an aqueous polyurethane resin dispersion dispersed in an aqueous medium, Provided is an aqueous polyurethane resin dispersion in which the high molecular weight polyol contains a polyester polycarbonate polyol having an alicyclic structure in the main chain. The high molecular weight polyol preferably contains a polyester polycarbonate polyol having an alicyclic structure in the main chain, a polycarbonate polyol, and a polyester polyol. |
