A coating material includes a first aqueous dispersion (A) and a second aqueous dispersion (B) wherein a dispersoid of the first aqueous dispersion (A) has an average particle diameter of 1 to 20 &#x3bc;m and a dispersoid of the second aqueous dispersion (B) has an average particle diameter 1/100 to &#x2155; of that of the dispersoid of the first aqueous dispersion (A), and the mass ratio (the aqueous dispersion (A)/the aqueous dispersion (B)) of the dispersoid of the first aqueous dispersion (A) to the dispersoid of the second aqueous dispersion (B) is 2/1 to 100/1. Also provided is a container, which is coated with the coating material and has excellent properties.

It is an object of the present invention to provide a novel aluminum tube of an oval cross section that has a wider range of applications and added values. A disk-shaped metal slug () is impact-extruded with the use of a die () and a punch () each having an optimally designed structure to form a metal tube (T) integrally including a mouth, a shoulder and a body of an oval cross section. A hem portion of the oval body of the tube (T) thus formed and hardened by the impact extrusion is once deformed into a circular shape, and then trimmed off by a turning operation.
