Abstract:
An article which includes a bi-colored metallic coating electrodeposited directly on a metallic cathode, such that where the article comprises a substantially planar surface, said coating possesses a visual first color when viewed from a first angle to said surface and it possesses a visual second and different color when viewed at a second angle to said surface: said article having been made by a process which includes the step of electrodepositing said coating on a suitable metallic cathode from an electrolyte bath which comprises ions selected from the group consisting of molybdenum(VI)-containing ions and (Ni(II)âˆ’+Zn(II))âˆ’ containing ions, wherein the parameters ionic concentration, pH, bath temperature current density and current quantity are selected so that a bi-colored coating is obtained, subject to the condition that a current density is applied to said cathode within the range of 0.005 to 0.5 A/dm2.
