PROBLEM TO BE SOLVED: The present invention has an excellent tack-free property after drying a coating film and can be finely processed because it has photosensitivity, and the resulting cured film is excellent in flexibility, flame retardancy, and electrical insulation reliability Another object of the present invention is to provide a black photosensitive resin composition, a resin film, an insulating film, and a printed wiring board with an insulating film, in which the warp of the substrate after curing is small. SOLUTION: At least (A) a binder polymer, (B) a crosslinked polymer particle, (C) a thermosetting resin, (D) a photopolymerization initiator, (E) a phosphorus flame retardant, and (F) a black colorant. The said subject can be solved by using the black photosensitive resin composition characterized by doing. [Selection figure] None |
