Abstract
Increases in surface resistivity of electroless nickel coatings on polycarbonate-containing substrates are inhibited by employing two electroless nickel plating solutions. The first solution is one which deposits a metal layer containing phosphorus, if any, in an amount up to 5% by weight and is used to deposit a layer at least 0.5 micron thick. The second solution is one which deposits a layer containing phosphorus in the amount of at least 5% and preferably at least 6% by weight. Another metal layer may be interposed between the two nickel layers.
