Abstract

A method of making a colloidal metal dispersion that is useful as a toner fluid. The method involves reducing a palladium and/or platinum metal of a metallo-organic palladium and/or platinum metal salt in a dispersing medium that contains a soluble surfactant and a carrier liquid. The palladium and/or platinum metal of the metallo-organic metal salt is reduced in the dispersing medium to form elemental metal particles. The soluble surfactant is present in the dispersing medium in an amount sufficient to charge and stabilize the elemental metal particles as a colloidal metal dispersion.
