BACKGROUND OF THE INVENTION As a propellant used in aerosol cans, chlorofluorocarbon gas has been dominant in the past.
The use of CFCs has been regulated due to global environmental problems, and liquefied petroleum gas (hereinafter, referred to as “LPG”) and dimethyl ether (hereinafter, referred to as “DME”) have been used as propellants instead. Usually, the main body of the aerosol can is formed of a metal simple substance, and a container having an inner surface coated with an epoxy resin is used. However, there is a problem that the corrosion resistance to LPG and DME is poor. In addition, there is a container coated with a polyimide amide resin having excellent corrosion resistance instead of the epoxy resin, but there is a problem that it is expensive.
