摘要： An alkali-developable photosensitive resin composition comprises a carboxyl group-containing urethane resin having a biphenyl novolak structure, a photopolymerization initiator, and aluminum hydroxide and/or a phosphorus-containing compound. The composition may be formulated as a photocurable and thermosetting resin composition by further incorporating therein a thermosetting component having a plurality of cyclic ether groups and/or cyclic thioether groups in the molecule, besides the components described above. The photosensitive resin composition may further contain a colorant. By using the photosensitive resin composition or a dry film thereof, a printed wiring board having a flame-retardant cured film, such as a solder resist, formed from the halogen-free composition can be provided while imposing little burden on the environment, the cured film being flame-retardant and reduced in warpage and having various excellent properties including bending characteristics, resistance to soldering heat, and resistance to gold plating.
