Abstract

The present invention provides the following three laminates: First, a polyimide-metal laminate which is obtainable by applying to one side of a metal foil a silane-modified polyimide resin composition (A) comprising alkoxy-containing silane-modified polyimide (a) and a polar solvent (b), drying and curing the composition; Second, a polyamideimide-metal laminate which is obtainable by applying to one side of a metal foil a silane-modified polyamideimide resin composition (C-1) comprising methoxy-containing silane-modified polyamideimide (d), a polar solvent (b) and an inorganic filler (c), drying and curing the composition; and third, a polyimide-metal laminate in which the cured film of the above composition (A) has a metal plated layer thereon.
