<p>A water-base paint for coating the inside surface of a metallic can, said paint comprising fine particles of a polyester resin dispersed in an aqueous medium in the presence of a surface-active agent, wherein (A) the polyester resin comprises units derived from a dicarboxylic acid and units derived from a diol, the units derived from the dicarboxylic acid containing units derived from terephthalic acid and units derived from isophthalic acid in a mole ratio of from 10:90 to 80:20, and at least 30 mole % of the units derived from the diol being derived from ethylene glycol, (B) the surface-active agent is composed of at least one compound selected from alkylaryl sulfonic acid salts, alkylsulfonic acid salts, dialkylsulfosuccinic acid salts, alkylphosphoric acid salts, polyoxyethylene alkylarylether sulfonic acid salts and polyoxyethylene alkylether sulfonic acid salts, and (C) the fine particles of the polyester resin have an average particle diameter of not more than 3 microns. e</p> |
