Abstract: A photosensitive resin composition according to the present disclosure, contains an acid-modified vinyl group-containing resin (A), a thermosetting resin (B), a photopolymerization initiator (C), and a photopolymerizable compound (D), in which the photopolymerizable compound includes a photopolymerizable compound having a polyoxyalkylene chain and an ethylenically unsaturated group.

Abstract: There is provided a photosensitive resin composition comprising (A) a photopolymerizable compound having an ethylenically unsaturated group and an acid substituent, (B) a curing agent, (C) a photopolymerization initiator, and (D) a photopolymerizable compound, wherein the photopolymerizable compound (D) is a polyfunctional monomer which has a skeleton (X) derived from a polyhydric alcohol and having three or more bonding groups (a), each bonded to another structure and corresponding to a hydroxy group from which the hydrogen atom has been removed, and which has three or more (meth)acryloyl groups bonded directly or indirectly to the bonding groups (a), and wherein at least one (meth)acryloyl group of the three or more (meth)acryloyl groups is bonded to the bonding group(s) (a) via a linking group. There are also provided a dry film using the photosensitive resin composition, a printed wiring board, and a method for producing the printed wiring board.
