FIELD: technological processes; packaging and storage.

SUBSTANCE: invention relates to a product with a coating composition applied thereto. Proposed is a product containing a housing or the lower part of a jar for a food product or beverage and the composition of a coating applied to it (on it), while the coating composition includes an aqueous dispersion, which contains the reaction product: (a) a hydrophobic vinyl additive polymer containing pendant or terminal ethylenically unsaturated groups derived from a mixture of vinyl monomers, including vinyl monomers containing two or more ethylenically unsaturated groups of different reactivity; (b) a mixture of vinyl monomers comprising a vinyl monomer containing carboxyl groups; wherein the reaction product contains groups with active hydrogen and is at least partially neutralized by a base and dispersed in an aqueous medium; the aqueous dispersion is essentially free of bisphenol A and its derivatives. Also, a method for coating a metal can surface for food or beverages is disclosed.

EFFECT: coating films have suitable packaging properties during storage.
