ABSTRACT:
A hydrophilic activating catalytic solution for electroless plating is a mixture of lactate, palladium and alkaline medium. The solution enables depositing palladium catalyst in a short time radiation exposure and removing unwanted photo-sensitive film more effectively by water or the like. The lactate preferably comprises copper lactate and/or zinc lactate and the palladium salt is preferably palladium chloride.
