SURFACE-TREATED COPPER FOIL, PROCESS FOR PRODUCTION OF THE SURFACE-TREATED COPPER FOIL, AND COPPER-CLAD LAMINATES MADE BY USING THE FOIL

摘要

The invention aims at providing a surface-treated copper foil provided with a silane coupling agent treatment layer, which foil is improved in the tight adhesion observed when laminated with a resin substrate by hot pressing. In order to attain the aim, the invention provides a surface-treated copper foil having a silane coupling agent treatment layer on the adhesive surface to be bonded to a resin substrate, characterized in that the silane coupling agent treatment layer is formed with a bifunctional silane coupling agent having -Si(OCH<SUB>3</SUB>) functional groups at both ends of the chemical structure. The bifunctional silane coupling agent is any of bis-?-trimethoxysilylpropyl- amine, bis-?-trimethoxysilylpropylethylenediamine, and bis-? -trimethoxysilylethane.
