Abstract

Substrates for printed circuit boards and the like, in the form of a substrate base layer and at least one adherent layer fixedly attached thereto. The adherent layer preferably comprises a thermoplastic material having a glass transition temperature in the range of about 180.degree. and about 245.degree. C., or a thermosetting material capable of B-stage curing. The preparation of the novel substrates and printed circuits using the substrates and conductive traces formed with electrically-conductive ink compositions is also described.
