<P>PROBLEM TO BE SOLVED: To provide a method for easily producing a conductive silver film at high speed, which is used as an antenna of non-contact type media. <P>SOLUTION: The method for producing the conductive silver film used as the antenna of the non-contact type media comprises: a first step of producing a substrate by forming a porous layer made of fine particles and a resin binder on a base, forming a layer containing a resin as a main component on the porous layer, and adding compounds selected from a compound having halogen in its molecule by ionic bond and thiosulfate to the porous layer and/or the layer containing the resin as the main component; and a second step of forming the conductive silver film by applying or printing a composition containing silver ultrafine particles, which contains silver ultrafine particles with an average particle diameter of 0.1 μm or less, on a layer containing the resin layer as the main component formed on the substrate. <P>COPYRIGHT: (C)2012,JPO&INPIT |
