PROBLEM TO BE SOLVED: To provide an alkali-developable photosensitive resin composition which causes less outgassing and is excellent in dry-to-touch property and developability, a dry film comprising the composition, cured products thereof, and a printed wiring board having the cured products.SOLUTION: The alkali-developable photosensitive resin composition contains (A) a carboxyl group-containing resin, (B) a photopolymerization initiator, (C) an epoxy resin, and (D) a (meth)acrylic monomer. The alkali-developable photosensitive resin composition contains an acylphosphine oxide-based photopolymerization initiator as the photopolymerization initiator (B) and contains a bisphenol A novolac type epoxy resin as the epoxy resin (C). |
