<p><P>PROBLEM TO BE SOLVED: To obtain a coating composition capable of forming a coated film having excellent screw-forming processability and rigidity, and having high stability; and to provide a bottle-shaped can hardly causing corrosion of a bottle-shaped can body even if the can is filled with beverage containing a corrosive component. <P>SOLUTION: The coating composition comprises an epoxy-acryl copolymer obtained by bonding an acrylic resin (A) with an epoxy resin (B) within a range of the mass ratio (A)/(B) of (12/88) to (35/65). The acrylic resin (A) comprises 20-60 mass% methacrylic acid unit (a), 35-70 mass% styrene unit (b) and 1-10 mass% low-Tg polymer-forming monomer unit (c) providing a polymer having≤-40°C glass transition temperature (Tg), and the epoxy resin (B) contains 5-45 mass% phenoxy resin (ii). The bottle-shaped can is obtained by coating the coating composition on the inner surface of the body of the bottle-shaped can. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
