Zusammenfassung:	PROBLEM TO BE SOLVED: To obtain a coating for the inner surfaces of a three piece can such as the can for a food, containing no poisonous compound, releasing no poisonous material, containing no endocrine disrupter, satisfying processability, resistance to retorting treatment, and resistance to the contents, and excellent in resistance to deterioration of the processability with time, and resistance to over-baking. SOLUTION: This resin composition for the coating for the inner surfaces of the three piece can comprises (A) a polyester resin composed of polycarboxylic acid components in which 75-100 mol% is terephthalic acid, and 0-25 mol% is other polycarboxylic acid, and polyalcohol components in which 50-99 mol% is one or more kinds of 1,2-propane diol and/or 1,2-butane diol, and 1-50 mol% is other alcohol components, and (B) a cross-linking agent. The coated metal plate for the inner surface of the three piece can is obtained by coating the resin composition.
