innenwandbschichteten metal container with an excellent resistance to the zuhalt

摘要

PROBLEM TO BE SOLVED: To provide an aerosol container which is excellent in bonding property to a metal base of the container, inactiveness to a content, and corrosion resistance by coating a thermosetting type polyamide-imide paint wherein the absorbance rate of the imide group and the amide group is specified, on the internal surface. ;SOLUTION: On the top of a metal container, e.g., a monoblock can 1 for which a can body 2 and a can bottom part 3 are connected without a seam, a valve holding mounting cup 10 is joined for an aerosol container. On the internal surface of such an aerosol container, a thermosetting type polyamide-imide based paint, wherein the absorbance rate which is defined by an absorbance I₁₇₂₀ of the infrared characteristic absorption of the imide group at a wave number of approx. 1720cm^-1, and an absorbance I₁₆₅₀ of the infrared characteristic absorption of the amide group at a wave number of approx. 1650cm^-1, is 2.5 or higher and 10 or lower, is coated. The polyamide based film is formed by coating a composition wherein especially, a carboxyl group containing polyamide-imide resin, and a curing agent of which the major component is an epoxy resin are contained by a weight rate of 60:40 to 95:5, and by curing at a specified temperature.;COPYRIGHT: (C)1997,JPO
