FIELD: chemistry.
SUBSTANCE: coating composition contains a polyvinyl chloride polymer, an acrylic resin which is preferably a polymer obtained from monomer acrylates or methacrylates, such as acrylic acid, methyl acrylate, ethyl acrylate, propyl acrylate, butyl acrylate, pentyl acrylate, hexyl acrylate, methacrylic acid, methyl methacrylate, ethyl methacrylate, propyl methacrylate, butyl methacrylate, pentyl methacrylate, hexyl methacrylate resins, copolymer resins of said components or mixtures thereof, a cross-linking agent which is obtained from phenol, para-tert-butylphenol, xylenol or mixture thereof, and formaldehyde, an additive, a dye and a solvent component, and the composition essentially does not contain bisphenol A diglycidyl ether (BADGE) and bisphenol A resin. The coatings are suitable for containers made from three parts, as well as for metal cans made through deep-drawing. The coatings are particularly useful for covers which are torn in order to open due to their unusual flexibility and resistance to sterilisation.
EFFECT: composition provides coatings for metal cans which have suitable flexibility, resistance to scratching, adhesion and sterilisation during processing while in contact with food.
