Component (2) may be a polyalkoxylated alkyl phenol, a quarternary imidazolinium compound, polyvinyl pyrrolidone or a polyethylene- or polypropylene glycol which may carry C(5-25) alkyl end groups. Component (3) may be pyridine, quinoline, izoquinoline or acridine or a derivative thereof. General formulae for and long lists of components (2) and (3) are given. Concentrations of 1-25 g/l and 0.001-4 g/l respectively of these components may be used in a weight ratio of 100-1 to 0.5-1. Plating conditions may include a bath temperature of 10-60C, a c.d. of 0.5- 5A/dm<SP>2</SP>, a pH of 1-10, a plating time of 0.5-120 min and a plating thickness of 0.25-25 microns Barrel plating may be used. The plated substrate may be steel, Fe, Cu, brass, bronze, Ni or Ag and may be a thin coating on a non-conductive substrate. Specified baths contain (1) ZnSo 4 or ZnCl 2 and NH 4 Cl optionally with citric acid and NH 4 OH as buffer or (2) Zn and NH 4 sulphamates and NH 4 OH buffer, in addition to the components (2) and (3) above. The plated zinc may be chromated by conversion coating.
