Abstract

Articles made from Al (alloys) coated with an oxide layer (e.g. anodically) are coloured by subjecting them to electrolyci a.c. treatment in a soln. contg. salt (a) of a gp VIII metal(s), and to aniodic treatment in and electrolyte, which can be the same or different than in the a.c. stage; this electrolyte may also contain a dispersion, emulsion or soln of a resin (pref. acrylic and/or alkyd resin) to form a protective coating.
