    • PROBLEM TO BE SOLVED: To provide an aqueous coating composition suitable for coating the inner surface of a member of a lid of a can, without totally using a BPA-derived constituting component, also without substantially using a surfactant deteriorating the steam sterilization resistance of a cured coating after baking, forming a good emulsion and capable of forming a coated film excellent in steam sterilization resistance, processability and corrosion resistance. SOLUTION: This aqueous coating composition comprises: a compounded polymer (F) having 0 to 50°C glass transition point and obtained by radically polymerizing (A) an emulsified component containing (A1) an ethylenically unsaturated monomer in the presence of an aqueous solution or emulsion containing (B) a COOH-group containing components containing (B1) an acrylic copolymer having 20,000 to 100,000 number-average molecular weight and containing COOH group, (C) a basic compound and (D) water by (E) a non-water soluble initiator; and (G) a phenol resin.

    • PROBLEM TO BE SOLVED: To provide an aqueous coating composition suitable as an external surface coating for metallic cans and polyester film-coated drawn cans that forms a cured coating film hardly generating fumes derived from a benzoguanamine resin and therefore hardly staining the inside of coated matter to assure excellence in respect to hygiene and exhibiting good high-speed scratch resistance. SOLUTION: The aqueous coating composition comprises the benzoguanamine resin (b) containing a mononuclear component of a specific structure obtained by N-methylolization with formaldehyde of benzoguanamine and partially condensing the product followed by N-alkoxylation, an acrylic copolymer (c) comprising (i) to (iii) below: (i) an N-alkoxymethyl(meth)acrylamide; (ii) an α, β-monoethylenically unsaturated carboxylic acid; (iii) a (meth)acrylate monomer and/or a vinyl monomer copolymerizable with (i) and (ii) above and giving a copolymer, having a glass transition temperature of 20-80°C, of monomers (iii).
