It has been found that the prior activation of a palladium substrate, such as palladium electrolessly deposited onto nickel, in an aqueous solution of an alkali metal hydroxide, an alkali metal carbonate and a reducing agent, for example, dimethylamine borane, can provide an enhancement in the thickness and uniformity of electrolessly deposited gold when the activated substrate is placed in an electroless gold bath.
