ABSTRACT:
In a film with metal foil of the present invention, a metal foil is stuck to the surface of a resin film via an adhesive layer. The adhesive is formed by crosslinking an acrylic polymer obtained by the copolymerization of a (meth)acrylic acid ester with a carboxyl group-containing radically polymerizable monomer, with a polyfunctional compound having a functional group reactive with the carboxyl group. The film with metal foil is very useful for producing a multi-layer wiring board by the so-called transfer method. By using this film, there can be produced a multi-layer wiring board having a fine and highly dense wiring/circuit layer and having a very excellently flat surface.
