PRIMER, CONDUCTOR FOIL WITH RESIN, LAMINATE AND PROCESS FOR PRODUCING THE LAMINATE

摘要

A resin primer capable of bonding with satisfactory strength an insulator layer to a conductor foil whose surface is relatively not roughened; a conductor foil with resin; a laminate; and a process for producing the laminate. The resin primer comprises a resin with film forming capability whose rupture energy is 0.15 J or more. The conductor foil with resin comprises a conductor foil and a resin layer consisting of the resin primer. The laminate comprises a conductor foil, an insulating layer disposed opposite to the conductor foil, and a resin layer consisting of the resin primer which is interposed between the conductor foil and the insulating layer so as to be in contact therewith. This laminate can be produced by applying heat and pressure to a laminate comprised of the conductor foil with resin and, superimposed on the resin, a prepreg.
