Electroless composite Plating Solution and Electroless composite plating method

Abstract

An electroless composite plating solution comprising metal ions, a complexing agent for said metal ions, a hypophosphite serving as a reducing agent, a surface active agent, and a water-insoluble composite material, said surface active agent comprising a quaternary ammonium salt surface active agent which has two or more ethylene oxide groups and an alkyl group or a fluorine-substituted alkyl or alkenyl group, said quaternary ammonium salt surface active agent being cationic in nature or exhibiting substantially cationic properties under pH conditions of said plating solution.
