Photosensitive resin composition, photosensitive resin film, multilayered printed wiring board, semiconductor package, and method for producing multilayered printed wiring board

Abstract

Provided is a photosensitive resin composition containing: a photopolymerizable compound (A) having an ethylenically unsaturated group; a photopolymerization initiator (B); and an inorganic filler (F), in which the photopolymerizable compound (A) having an ethylenically unsaturated group includes a photopolymerizable compound (A1) having an acidic substituent and an alicyclic structure together with an ethylenically unsaturated group, and the inorganic filler (F) includes an inorganic filler surface-treated with a coupling agent without at least one functional group selected from the group consisting of an amino group and a (meth)acryloyl group. The present disclosure also provides a photosensitive resin composition for photo via formation, and a photosensitive resin composition for interlayer insulating layer. The present disclosure further provides: a photosensitive resin film and a photosensitive resin film for interlayer insulating layer, each of which contains the photosensitive resin composition; a multilayered printed wiring board and a semiconductor package; and a method for producing a multilayered printed wiring board.
