<p>A photosensitive resin composition which has high sensitivity while retaining properties such as suitability for tinting, resistance to plating, and removability; and a layered product. The photosensitive resin composition comprises (a) a carboxylated thermoplastic polymer, (b) an ethylenic addition-polymerizable monomer having a specific structure, (c) a photopolymerization initiator comprising a 2-(o-chlorophenyl)-4,5-diphenylimidazolyl dimer, and (d) a dye comprising Diamond Green. A layer of the composition is formed on a support layer. Also provided are a method of forming a resist pattern with the layered photosensitive-resin product and a process for producing a printed wiring board, lead frame, or semiconductor package.</p> |
