Abstract
1466708 Electrolytically colouring anodized aluminium SWISS ALUMINIUM Ltd 8 Nov 1974 [9 Nov 1973] 48443/74 Heading C7B Pre-anodized Al or Al alloy is coloured electrolytically using A.C. in an aqueous acidic bath containing at least one colour forming metallic salt and to which an amino-alcohol has been added. The metal salt may be of Ni, Co, Cu, Sn, Ag and/or Fe and the additive one or more of mono-, di- or triethanolamine. The latter may be added in amount at least 1 gpl before or during colouration to prevent a pH drop. In examples the pH of a Cu/Co/Ni sulphate bath containing H 3 BO 3 is controlled to 4À7, and the pH of a Sn/H 2 SO 4 bath is controlled to 1À4.
