ABSTRACT:
A process of electrolessly metallizing a body on the surface thereof with a metal coating incorporating particulate matter therein, which process comprises contacting the surface of said body with a stable electroless metallizing bath comprising a metal salt, an electroless reducing agent, a complexing agent, an electroless plating stabilizer, a quantity of particulate matter which is essentially insoluble or sparingly soluble in the metallizing bath, and a particulate matter stabilizer (PMS), and maintaining said particulate matter in suspension in said metallizing bath during the metallizing of said body for a time sufficient to produce a metallic coating with said particulate matter dispersed therein.
