Metal-clad laminate and process for producing the same
First Claim
1. A metal-clad laminate comprising:
- a base plate; and
a layer of metal foil on at least one side of said base plate;
said base plate including, in order, a first electrically insulating material layer composed of a cross-linked silane-modified polyethylene resin laminated to a layer of said metal foil, and a second electrically insulating material layer made of paper or cloth containing an epoxy resin, a silanol condensation catalyst or a mixture of said epoxy resin and said silanol condensation catalyst laminated to said first electrically insulating layer.

Abstract
A metal-clad laminate comprising a base plate composed of a plurality of electrically insulating material layers and a metal foil or foils laminated on one side or both sides of the base plate, characterized in that to at least the metal foil or foils is laminated an electrically insulating material layer composed of a silane-modified polyethylene resin sheet, that to the silane-modified polyethylene resin is laminated an electrically insulating material layer made of a paper or cloth containing an epoxy resin and/or a silanol condensation catalyst, and that the layer made of a paper or cloth contains 5 to 35% by weight of an epoxy resin and/or that to the layer made of a paper or cloth is laminated an electrically insulating material layer other than the above-mentioned two layers. Said metal-clad laminate has excellent characteristics such as low, ε, low tan δ and excellent moisture-resistant insulating property.
