    • The present invention is directed to an inter-laminar adhesive composition containing a liquid epoxy resin, a polyfunctional epoxy resin having a softening point higher than a lamination temperature of the adhesive and with two or more epoxy groups within the molecule; and a latent epoxy curing agent initiating a reaction at a temperature higher than the lamination temperature. The adhesive composition optionally contains a liquid resin other than the liquid epoxy resin and/or an organic solvent and the liquid resin includes the liquid epoxy resin, the organic solvent or both constituting from 10 to 55% by weight of the composition. This inter-laminar adhesive composition allows for the preparation of a multi-layer printed wiring board. The process for preparing the multi-layer printed wiring board is provided. The resulting multi-layer printed wiring board of the invention possesses excellent embedding properties in the internal-layer circuit, excellent surface smoothness and can be provided at high productivity levels in a building up process using the present adhesive.

    • A multilayer printed circuit board having resinous insulating layers and conductor layers alternately superposed on a circuit board with ample adhesive strength, a method for the production thereof, and a curable resin composition useful for the formation of resinous insulating layers are disclosed. The manufacture of the multilayer printed circuit board is accomplished by applying the curable resin composition to the surface of conductor layer of the circuit board, thermally curing the applied layer thereby forming resinous insulating layer, then boring a through-hole in the circuit board, treating the resinous insulating layer with a coarsening agent thereby imparting undulating coarsened surface thereto, subsequently coating the surface of resinous insulating layer and the inner surface of the through-hole with a conductor layer as by electroless plating, and thereafter forming a prescribed circuit pattern in the conductor layer. The curable resin composition comprises (A) epoxy resins and (B) an epoxy resin curing agent as essential components thereof and optionally contains a rubber component and a filler capable of being decomposed or dissolved by a coarsening agent. This composition contains in combination a bisphenol A type epoxy resin having an epoxy equivalent of not less than 400 and an epoxy resin having an epoxy equivalent of less then 400.
