    Abstract: There is provided a photosetting conductive paste that has a surface resistance of no greater than 200 m OMEGA /sq. upon curing by light irradiation. The photosetting conductive paste comprises conductive powder and a photosetting resin composition in specific amounts. The conductive powder contains dendritic conductive powder and scaly conductive powder at 80% or greater of che total conductive powder, the dendritic conductive powder having a mean particle size of 0.05-1.0 mu m, a specific surface area of 0.5-5.0 m /g, and the scaly conductive powder having a mean particle size of 1.0-10.0 mu m and a specific surface area of 0.5-5.0 m /g, wherein the weight ratio of the dendritic conductive powder and scaly conductive powder is 6/40 - 95/5. There is also provided a method of forming an antenna for a radio frequency identification medium that comprises printing the conductive paste on a substrate in an antenna-shaped pattern and curing it.
