METHOD FOR PRODUCING SILVER CONDUCTIVE FILM

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a silver conductive film capable of mass-producing a silver conductive film exhibiting sufficient conductivity by sintering silver fine particle each other even by heat treatment at low temperature in a short time.SOLUTION: The surface of a base material coated with a halide such as a chlorine compound is coated with a silver fine particle-dispersed solution obtained by dispersing silver fine particles of 30 to 70 mass% into an aqueous medium by flexographic printing, thereafter, heating and firing are performed at 60 to 200°C for 0.1 to 5 s in an infrared ray (IR) heating furnace installed in the printing path thereof, thus a silver conductive film is formed on the base material by a roll to roll continuous system.
