Abstract
Aqueous coating composition, useful on metal substrates which are deep drawn after being coated, e.g., bottle caps, are made from (A) a blend of an aqueous solution of the reaction product of a glycidyl polyether of a dihydric phenol, a polyethylene glycol and phosphoric acid, (B) an aqueous dispersion of a glycidyl polyether of a dihydric phenol and, optionally, (C) an alkoxymethylmelamine.
