WIPO Patent Application WO/2016/006513
Kind Code:
A1
Abstract:
[Problem] To provide an electro-conductive paste having performance in regard to being transferred from an intermediate transfer body to a print material that is superior to that of the prior art when a solar cell electrode is formed using intaglio offset printing, the print material being a material to be printed upon. Using the electro-conductive paste, it is possible to form, on a substrate surface, an electrode having a smaller width and thickness than the prior art, the electro-conductive paste furthermore having a substrate that is not susceptible to damage during printing. [Solution] An electro-conductive paste composition containing at least a resin binder (A) and a resin binder (B) that have mutually different resins, an electro-conductive powder (C), an inorganic binder (D), and an organic solvent (E), wherein the electro-conductive paste composition is characterized in that the resin binder (A) comprises ethyl cellulose, the resin binder (B) comprises polyvinyl butyral, and the weight ratio of the resin binder (A) and resin binder (B) is 2:8-8:2.
