<p>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) polyethers having the formula H(OCxH2x)nOH where x is from 2 to 4 and n is a number such that the polyether has a weight average molecular weight of from about 200 to about 1000; (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.</p> |
