This invention provides water-based paint compositions containing waterdispersible acrylic polymer particles, hydroxyl- containing resin and curing agent, the water-dispersible acrylic polymer particles having a weight-average molecular weight of at least 1,100,000 and an absorbance value not higher than 0.2 at a wavelength of 330 nm, as measured with spectrophotometer in the state of liquid dispersion at a mass concentration of 1.35% in 1,4- dioxane solvent; and the compositions excelling in finished appearance such as coated surface smoothness and coating film performance such as chipping resistance and water resistance. |
