摘要: In an additive process for producing printed wiring boards, by using a developer comprising a chlorine-free organic solvent and an alkaline aqueous solution and as a resist material a copolymer of methacrylic acid and methyl methacrylate or the like, the production steps are simplified even if a substrate having a large area is used, and abolishment of chlorine-containing organic solvent as a developer becomes possible.
