Abstract
The present invention provides a coating composition for cans comprising 100 parts by mass of a neutralized acrylic resin-modified epoxy resin (A), and from 1 to 50 parts by mass of anionic polymer crosslinked fine particles (B), (A) and (B) being dispersed in an aqueous medium, wherein the anionic polymer fine particles (B) are polymer fine particles comprising a polymer having an acid value of from 10 to 120 mg KOH/g and being produced by polymerizing radically polymerizable unsaturated monomers comprising from 2 to 30% by mass of a carboxyl group-containing radically polymerizable unsaturated monomer (b1), from 2 to 30% by mass of a polyvinyl compound (b2) and from 40 to 96% by mass of other radically polymerizable unsaturated monomer (b3) in the presence of water.
