Zusammenfassung: | The present invention relates to provision of a photosensitive resin composition, a photosensitive resin composition for photo via formation, and a photosensitive resin composition for interlayer insulating layer, each of which is excellent in both photosensitive characteristics and strippability from a support film. In addition, the present invention relates to provision of a photosensitive resin film and a photosensitive resin film for interlayer insulating layer, each of which is composed of the aforementioned photosensitive resin composition. Furthermore, the present invention relates to provision of a multilayer printed wiring board and a semiconductor package, and to provision of a method for producing the aforementioned multilayer printed wiring board. Specifically the photosensitive resin composition is a photosensitive resin composition containing (A) a photopolymerizable compound having an ethylenically unsaturated group, (B) a photopolymerization initiator, and (C) a thermosetting resin, wherein the photopolymerizable compound (A) having an ethylenically unsaturated group includes (A1) a photopolymerizable compound having an acidic substituent and an alicyclic structure together with an ethylenically unsaturated group; and further, the thermosetting resin (C) includes (C1) a thermosetting resin having an alicyclic structure, and the content of the component (C1) is 10 parts by mass or more based on 100 parts by mass of the component (A). |
