ETCHING RESIST MATERIAL AND METHOD OF MANUFACTURING PRINTED WIRING BOARD

摘要

PROBLEM TO BE SOLVED: To provide an etching resist material that enables a printed wiring board which has a low defective fraction and is rich in reliability to be manufactured at low cost, and a method of manufacturing the printed wiring board.SOLUTION: There is provided an etching resist material consisting of an imidazole compound having a (meth) acryloyl group. The method of manufacturing a printed wiring board includes: a process of forming a protective film on a surface of copper by bringing the etching resist material into contact with a copper-clad laminate; a process of irradiating the protective film with an active energy ray; a process of etching copper which does not have the protective film formed on the surface; and a process of removing the protective film.
