Process for preparing conductive material

Abstract

It is to provide a process for preparing a conductive material in which transparency and conductivity are both high, and storage stability is high, and further, in a process for preparing a conductive material utilizing ultra fine silver particles, to provide a process for preparing a conductive material having high conductivity without requiring a calcination step which has conventionally been required. A process for preparing a conductive material having a conductive pattern containing silver on a support, which process for preparing a conductive material comprises acting at least one of the following mentioned (I) to (IV) on the pattern portion containing silver provided on the support: (I) a reducing substance, (II) a water-soluble phosphorus oxo acid compound, (III) a water-soluble halogen compound, (IV) warm water of 55° C. or higher.
