Abstract

PURPOSE: To obtain a highly dark black-colored aluminium which is excellent in fire resistance, heat resistance, bleeding resistance upon sealing hole, etc., by coloring an anodic oxidation treated aluminium with a 1:2 type chromium complex salt having a specific structure.
CONSTITUTION: An anodic oxidation treated aluminium is dipped in an aqueous solution of a complex salt dye (e.g., the compound of the formula II) of the formula I (where X⊕ is H, Na, K or NH4 ion and the substitution position of NH2 group is 4- or 7-position of naphthol) for coloration. The coloration can be performed in a temperature range from room temperature to boiling point but particularly preferably temperature is 40W70°C, and also the preferable pH of the immersion bath is 4.5W7.5. The aluminium used includes, besides pure aluminium, ones capable of being treated by anodic oxidation with an aluminium alloy, e.g., Al-Mg, Al-Si, Al-Mg-Si, etc.
