Abstract:
An object of this invention is to obtain an aqueous polyurethane resin dispersion having excellent drying property, which can provide a coating film having high hardness. The aqueous polyurethane resin dispersion comprises a polyurethane resin obtained by reacting (a) a polyol compound, (b) a polyisocyanate compound, (c) an acidic group-containing polyol compound and (d) a chain-elongating agent, which is being dispersed in an aqueous medium, wherein the above-mentioned (a) polyol compound contains at least (a1) a polycarbonate polyol having an alicyclic structure at the main chain and (a2) a polymer polyol having a number average molecular weight of 500 to 5000 and having no alicyclic structure.
