Document Type and Number:
WIPO Patent Application WO/2011/089738
Kind Code:
A1
Abstract:
Disclosed are a coated high-gloss aluminum material (1) for a housing, which comprises a base material (2) formed of an aluminum alloy and a coating film (3) formed on the surface thereof, and a method for producing the same. In the coated high-gloss aluminum material (1) for a housing, the coating film (3) is formed by electrodeposition coating on the surface of the base material (2) having a surface roughness (Ra) of 0.001-0.05 μm. The method for producing the coated high-gloss aluminum material (1) comprises a step for producing the base material and an electrodeposition coating step. In the step for producing the base material, the base material (2), which is formed of an aluminum alloy and has a surface roughness (Ra) of 0.001-0.05 μm, is produced by a technique selected from among roll transferring, chemical polishing, electrolytic polishing and mechanical polishing. In the electrodeposition coating step, the coating film (3) is formed on the surface of the base material (2) by electrodeposition coating.
