<p>In order to obtain a highly reliable multilayer printed-wiring board of the build-up type (consisting of alternate layers of conductor circuitry and insulating materials) which has an easily formed copper plating layer of high adhesive strength, and which is also high in heat resistance, an epoxy resin composition is employed for interlayer insulation and includes (A) an epoxy resin having two or more epoxy groups in each molecule, (B) a phenolic resin composition comprising a mixture, or condensation product of phenols, a compound having a triazine ring and aldehydes, the mixture or condensation product being substantially free from any unreacted aldehydes, or methylol group, (C) a rubber component, and (D) a curing accelerator. Minute protrusions form on the surface of the composition by thermosetting at or above 80 DEG C, and have a maximum height (Ry)≥1.0 mu m. A process for manufacturing a multilayer printed-wiring board using the composition is provided.</p> |
