Abstract of the Disclosure - This invention relates to a novel coating to be used for the lining of the interior of food, beer and beverage cans. The coating is prepared by emulsion polymerization by a two step process in which the ethylenically unsaturated carboxylic acid monomers are copolymerized in the presence of initiators to form a seed latex in the first stage; subsequently, the seed latex is neutralized with base, and the pH sensitive monomers are copolymerized in the second stage, which comprises from 68 to 90% by weight of the total monomer composition. The composition and rheology of the polymer result in a coating with excellent film properties and good application characteristics for interior can coatings. - i -
