Abstract
A method of transferring a chemical activating agent from an applicator to a substrate surface involves providing an applicator having a raised application surface, applying a chemical activating agent to the application surface, contacting the substrate surface with the application surface, and removing the applicator. The chemical activating agent is transferred in a form in which it is capable of effecting a chemical reaction, such as catalysis, at the surface. Thus, following transfer of the chemical activating agent to the surface in a pattern, a metal can be plated at the substrate surface in the pattern. The applicator can be an elastomeric stamp having a raised portion defining a stamping surface.
