摘要:
Disclosed are a primer layer for plating process exhibiting high adhesiveness to an electroless copper plating and capable of coping with high density of wirings of semiconductor packages; a laminate for wiring board having the primer layer and a method for manufacture thereof; and a multilayer wiring board having the primer layer and a method for manufacture thereof. Specifically disclosed are a primer layer for plating process formed of a resin composition for primer layer including (A) a polyfunctional epoxy resin, (B) an epoxy resin curing agent, and (C) a phenolic hydroxyl group-containing polybutadiene-modified polyamide resin having specified structural units, wherein a blending proportion of the component (C) is 5 parts by mass or more and less than 25 parts by mass based on 100 parts by mass of a total sum of the component (A) and the component (B); a laminate for wiring board having the primer layer and a method for manufacture thereof; and a multilayer wiring board having the primer layer and a method for manufacture thereof.
