| 摘要 |
This invention relates to dry colloidal catalyst compositions of catalytic metals and to methods for formation of said dry compositions. The dry catalysts, upon dispersion in an aqueous acid solution of pH below 1, are used to render surfaces receptive to the deposition of an electroless metal. The liquid catalyst compositions, from which the dry compositions are formed, are those acidic compositions of U.S. Pat. No. 3,011,920.
