PROCESS TO CATALYIZE OR CONDUCT A REACTION OF ONE OR MORE CHEMICALS ON A SURFACE, CATALYST SYSTEM, METAL DEPOSITION SURFACE WITHOUT ELECTRICITY, COMPOSITION AND PRINTED WIRING BOARD

摘要

In a process for catalysing or conducting a reaction on a surface there is formed on the surface a monolayer of positively charged polymer in the form of an aqueous solution or a stable aqueous colloidal dispersion of particles of particle size diameter less than 3 micrometers, the polymer having, distributed therethrough, active agent capable of reacting with, or catalysing the reaction of, said one or more chemicals upon contact. This contact is then effected. In one aspect of the process a catalyst system, which is especially useful for the electroless deposition of a metal, for example a conductive metal on a printed circuit board surface or through hole, is formed.
