GOLD NANOPARTICLE DISPERSION LIQUID FOR FORMING CONDUCTIVE COATING FILM, METHOD FOR PRODUCING SAME, AND CONDUCTIVE COATING MATERIAL COMPOSITION CONTAINING SAME

摘要

The present invention provides: a gold nanoparticle dispersion liquid for forming a conductive coating film, which is capable of forming a conductive coating film having a low specific resistance by firing at low firing temperatures even in cases where the ratio of gold nanoparticles having a particle diameter of less than 5 nm is suppressed to less than 90% on a number basis; and a method for producing the gold nanoparticle dispersion liquid for forming a conductive coating film. The present invention provides a gold nanoparticle dispersion liquid for forming a conductive coating film, which contains gold nanoparticles that have a number average particle diameter within the range of 3.98-5.24 nm and a ratio of the number of particles having a particle diameter of less than 5 nm relative to the total number of particles within the range of 64-83%.
