Abstract
Aqueous coating compositions consist essentially of: (a) a water-insoluble film-forming polymeric resin; (b) water-insoluble agglomerated particulate beads of urea, melamine or phenol and formaldehyde; (c) caprolactone-polyol adducts having a weight average molecular weight of from about 250 to about 2500; (d) pigments; and (e) water. The aqueous coating compositions are especially useful for imparting to metal coil a low gloss pigmented protective finish having good metal marking resistance.
