ABSTRACT:
This invention relates to aqueous solutions containing Ni cation and hypophosphite anion which have a Ni cation concentration greater than 36 grams/liter. Such solutions have utility in electroless nickel plating baths and processes as make-up solutions and replenishing solutions. The increased concentration of Ni cation results from the addition of the nickel salt of an alkyl sulfonic acid to the solution.
