Abstract
An electroless nickel plating method and composition is disclosed wherein a soluble acetylenic compound is included within the plating bath in small amounts effective to improve the specularity of the nickel deposit without substantially decreasing the electroless plating rate of the bath. The method and compositions of the invention are useful in producing mirror-bright electroless nickel coatings free of haze.
