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) polyethers having the formula EQU H(OC.sub.x H.sub.2x).sub.n OH 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.
