US 2013/0256017 A1 · LAMINATED STRUCTURE, DRY FILM AND METHOD OF PRODUCING LAMINATED STRUCTURE

Abstract

[Problems] The present invention provides a laminated structure comprising resin insulating layers which exhibits excellent adhesion to a base material and has excellent insulation reliability; and a dry film used for the production of the laminated structure. [Means for Solution] Provided is a laminated structure comprising a base material and a plurality of resin insulating layers formed thereon, which is characterized in that a layer of the plurality of resin insulating layers, which is in contact with the base material, is a resin insulating layer (A) which contains a curing accelerator composed of an N atom-containing basic compound; and that the laminated structure comprises a resin insulating layer (B) which contains a P atom-containing curing accelerator in addition to the resin insulating layer (A) which contains a curing accelerator composed of an N atom-containing basic compound.
