Abstract
An aqueous coating composition characterized in that the composition comprises: (A) a water-dispersible film-forming acrylic polymer, (B) a crosslinking agent prepared by dispersing a hydrophobic melamine resin in water in the presence of a water-soluble resin, the hydrophobic melamine resin being up to about 20 in solvent dilution ratio when diluted with a water/methanol solvent mixture (35/65 in weight ratio) and about 500 to about 4000 in weight average molecular weight, and (C) a pigment. The composition is very suitable for use in the two-coat one-bake coating method as a base-coat composition.
