Abstract
A process for the production of metallized bodies, such as printed circuits, dials, nameplates, metallized plastics, glass, ceramics and the like, comprising treating a base with a composition comprising a metal salt reducible to catalytically active metal nuclei and a secondary reducing agent, and thereafter exposing the base to a primary chemical reducing agent to produce a layer of metal nuclei on the surface of the base. Exposing the sensitized base to an electroless metal deposition solution causes electroless metal to deposit on the nuclei.
