Abstract
1419224 Electrolytic colouring of anodized Al or Al alloy SUMITOMO CHEMICAL CO Ltd 20 March 1974 [20 March 1973 22 Nov 1973] 12485/74 Heading C7B Aluminium or aluminium alloy is anodized in a sulphuric acid electrolyte or in an aromatic sulphonic acid electrolyte, e.g. sulphosalicylic acid or sulphothalic acid, containing sulphuric acid; and is thereafter cathodically coloured in an aqueous solution of a nickel salt e.g. of NiSO 4 , NiCl or Ni acetate, which solution contains less than 12 ppm sodium ion. The colouring bath may also contain boric acid, H 2 SO 4 , an organic acid or NH<SP>+</SP> salt, or, to modify the colour produced, a sulphate or chloride of Sn, Co and/or Cu. A nickel anode may be used for colouring. The sodium content of the bath may be lowered by passage of the bath through a column of strongly acidic Ni-type cation-exchange resin.
