Abstract: Disclosed are metal plating compositions for plating a metal on a substrate. The metal plating compositions include compounds which influence the leveling and throwing performance of the metal plating compositions. Also disclosed are methods of depositing metals on a substrate.

Abstract: The plating bath for the deposition of satin nickel deposits according to the present invention contains at least one quarternary ammonium compound and at least one polyether, the at least one polyether having at least one strongly hydrophobic side chain. As compared to prior art plating baths, this acid plating bath has the advantage that it enables a long period of operation or heating and cooling cycles or filtration cycles, makes it possible to perform the filtration needed for continually operating the bath without using active carbon, requires a lower concentration of nickel than prior art baths to produce the satin gloss finish and has a reduced sensitivity to wetting agents that have been dragged in.

Abstract: A method of electrodepositing nickel and nickel alloys on a metal surface of a substrate wherein a Watts or other nickel deposition electrolyte is used as the bath in the presence of a conventional base brightener. According to the invention, an ethylene-oxide adduct or propylene-oxide adduct or ethyleneoxide/propylene-oxide adduct is added in an amount less than 5 mg/l and the deposition is carried out at 40 to 75.degree. C. and the concentration of the adduct and the temperature are so selected that during operation and with visual inspection there is no cloudiness nor any diffuse scattering of light incident upon the bath.
