Abstract:
An aqueous primer composition of the present invention includes a water-dispersible polyisocyanate (A) and an acrylic resin water dispersion (B), wherein a polystyrene equivalent weight average molecular weight, determined using gel permeation chromatography, of an acrylic resin in the acrylic resin water dispersion (B) is 350,000 or more, and a glass transition temperature, determined by using a differential scanning calorimeter, of the acrylic resin is 15° C. to 130° C., and a weight ratio between the water-dispersible polyisocyanate (A) and the acrylic resin water dispersion (B) is (A):(B)=70:30 to 50:50.
