Abstract
A silver conductive film is formed on a substrate in a continuous roll-to-roll system by applying a fine silver particle dispersing solution, which contains 30 to 70 wt % of fine silver particles dispersed in a water based dispersing medium, to the substrate via a halide, such as a chlorine compound, which is applied to the substrate, by flexographic printing, and thereafter, heating the substrate at 60 to 200° C. for 0.1 to 5 seconds in an infrared (IR) heating open, which is installed on the printing path, to carry out calcination.

A method for producing a silver conductive film, the method comprising the steps of:
- applying a halide to a substrate;
- applying a fine silver particle dispersing solution, which contains fine silver particles in a water based dispersing medium, to the substrate via the halide;
- and
- thereafter, heating the substrate at 60 to 200° C. for 0.1 to 5 seconds to carry out calcination to form a silver conductive film on the substrate.
