Abstract
In a wholly additive process for depositing a patterned metal layer on an insulating substrate, the sensitized and activated substrate is coated with photoresist; a desired pattern is formed in the photoresist layer by exposing it to a mask and developing it using conventional techniques; the patterned surface is then contacted with a second developer solution containing the activator; a metal pattern is deposited by electroless metal plating; and the photoresist is removed.
