Abstract:
A metal film adhered body comprising a substrate, an adhesive layer formed thereon, said adhesive layer having a roughened surface, and a metal film arranged on the adhesive layer, wherein the adhesive layer is formed by dispersing a removable particulate substance into a cured heat-resistant resin matrix comprised of a resin composite comprising a thermoplastic resin and at least one resin selected from a thermosetting resin and a photosensitive resin,wherein said particulate substance is at least one of dissolution-removable or decomposition-removable, and wherein said matrix comprises 15 to 50 wt. % of said thermoplastic resin, and wherein said dissolution-removable particulate substance is at least one selected from the group consisting of metal particles, resin particles soluble in alkali and resin particles soluble in an organic solvent, and wherein said decomposition-removable particulate is emulsion-polymerized amino resin having a low cross-linking degree comprising melamine resin, urea resin and guanamine resin, wherein said thermosetting resin comprises at least one functional group substituted by a photosensitive group.
