Abstract:
1. A resin coated seamless aluminum can having excellent corrosion resistance and adhesiveness, comprising: an organic-inorganic composite surface treated layer made of adhesion quantities of a zirconium compound, a phosphorus compound and an organic compound formed on at least an inner surface of an aluminum alloy sheet, wherein an adhesion quantity of the zirconium compound is 2 to 20 mg/m the organic compound is formed of an organic polymer having structure units expressed by the following formula (I) and an average molecular weight of the organic polymer is 1,000 to 100,000 when all X are hydrogen atoms, and a thermoplastic resin layer further formed on the organic-inorganic composite surface treated layer, wherein, in the formula (I), X in respective structural units are independently constituted of a hydrogen atom or a Z group expressed by the following formula (II) and an introducing ratio of the Z group per one benzene ring is 0.3 to 1.0, and wherein, in the formula (II), R wherein the resin coated seamless aluminum can is produced by deep drawing, drawing and ironing or stretch drawing of the organic polymer coated aluminum alloy sheet.
