Method for depositing free metal containing latex
First Claim
1. A method comprising the step of electrolessly depositing one or more free metals onto a substrate and concurrently coating a polymer of a latex onto said substrate, said latex containing above about 1 weight percent of said polymer and above about 0.001 weight percent of salt containing metallic cations.

Abstract
Free metals are electrolessly deposited in the presence of a latex of a polymer. Sols or gels containing metal-containing ions are mixed with a latex and the resulting sol/latex subsequently contacted with a reducing agent. The presence of the reducing agent with the latex at appropriate deposition conditions converts the metallic ions to free metal. The free metal is deposited in the form of a surface coating composition onto substrates for such purposes as decoration of substrates and electrically conductive coatings.
