Method of forming metal pattern, and metal salt mixture

摘要

An objective is to provide plate making printing exhibiting conductivity and flexibility with respect to a flexible substrate, and to provide a method of forming metal patterns via non-plate making printing, and a metal salt mixture usable for the method. Also disclosed is a method of forming a metal pattern possessing the steps of conducting patterning on a substrate with a metal salt mixture for the metal pattern formation possessing a metal salt and a reducing agent, and having a viscosity of 3 - 50 mPa·s at 25 °C, and forming the metal pattern via heating to a temperature of 80 - 400 °C.
