Abstract
Flexible printed circuits comprising copper circuitry electrolessly deposited on an activated ink coating prepared by heating a wet ink comprising a polymer, e.g. polyvinyl chloride or a butadiene polymer, and a Group 1B or 8 compound, e.g. palladium dichloride, which is adapted to drying at room temperature to a catalytically inert ink. Selective areas of the ink activated by application of heat or light, e.g. a laser, are catalytic to electroless deposition of copper.
