Title: METAL FOIL WITH RESIN LAYER, METAL-CLAD LAMINATE, AND METHOD FOR PRODUCING PRINTED WIRING BOARD
Abstract:
This metal foil with a resin layer comprises a resin layer on at least one surface of a metal foil. The resin layer contains, per 100 parts by mass of a polyphenylene ether compound, from 50 parts by mass to 150 parts by mass (inclusive) of a styrene butadiene block copolymer, from 10 parts by mass to 78 parts by mass (inclusive) of an epoxy resin, and a curing agent. It is preferable that the curing agent is a biphenyl aralkyl phenolic resin. It is also preferable that the epoxy resin contains from 70 parts by mass to 100 parts by mass (inclusive) of an ether type epoxy resin per 100 parts by mass of all epoxy resins.
