Abstract
Electroless deposition of copper from solution onto a substrate, particularly a polymeric laminate for use in electronic circuitry, is accomplished by first treating said substrate with a stilbene-based fluorescent brightener to sensitize said substrate and thereafter contacting said substrate first with a solution of a catalytic metal and then with an electroless copper plating solution.
