Zusammenfassung:	To provide a coating composition which is superior to opening property after heat treatment and can form coating superior in workability and acid tolerance without using bisphenol skeletons such as BPA and epoxy resin having biphenol skeletons as raw materials, and a can having the coating of the coating composition.SOLUTION: A coating composition contains epoxy resin (A) and a curing agent (B). The epoxy resin (A) is a reaction product of epoxy group in epoxide having neither bisphenol skeleton nor biphenol skeleton, and carboxyl group of polyester having carboxyl group.SELECTED DRAWING: Figure 1 【課題】ＢＰＡなどのビスフェノール骨格や、ビフェノール骨格を有するエポキシ樹脂を原料として用いず、熱処理後の開口性に優れ、加工性、耐酸性に優れた塗膜を形成し得る塗料組成物、及び、当該塗料組成物の塗膜を有する缶を提供することを目的とする。【解決手段】エポキシ樹脂（Ａ）と、硬化剤（Ｂ）を含有する、塗料組成物であって、前記エポキシ樹脂（Ａ）が、ビスフェノール骨格及びビフェノール骨格のいずれも有さないエポキシ化合物中のエポキシ基と、カルボキシル基を有するポリエステルのカルボキシル基との反応生成物である、塗料組成物。【選択図】図１
