Abstract
Substrate composites, well adopted for the production of metallized printed circuits and facilely prepared by, e.g., papermaking procedures, include a central core layer comprising fibrous cellulosic material or flaked mica within a matrix of a thermosetting resin binder, said central core element having coextensively laminated to at least one of the face surfaces thereof, a lamina of a thermosetting resin comprising non-conductive metal oxide filler material distributed therethrough, and said metal oxide being borohydride reduceable and reactive to form unstable metal hydride intermediates.
