To provide a printing method of a conductive article.SOLUTION: In a printing system 100, one of a first ink composition and a second ink composition is adhered on a surface of a substrate 102, and a deposition region is formed on a surface 110 of the substrate or a previously printed article 103 on the surface of the substrate. The first ink composition contains solution of a metal compound, the second ink composition contains a solution of stable free radical, and another of the first and second ink composition is adhered to the deposition region, the first and second ink compositions are mixed, chemical reduction of the metal compound is derived by deposition of the stable free radical and a metal of the metal compound, and a conductive article containing deposited metal is formed by removing a solvent from the deposition region.SELECTED DRAWING: Figure 1 【課題】導電性物体の印刷方法を提供する。【解決手段】印刷システム１００において、基材１０２の表面に第１インク組成物と第２インク組成物のうちの一方を付着させて、基材の表面１１０上または基材の表面上の以前に印刷された物体１０３上に堆積領域を形成する。ここで、第１インク組成物が金属化合物の水溶液を含み、第２インク組成物が安定なフリーラジカルの水溶液を含み、第１と第２インク組成物のうちの他方を堆積領域に付着させて、第１と第２インク組成物を混合し、安定なフリーラジカルおよび金属化合物の金属の沈殿により、金属化合物の化学的還元を誘導し、堆積領域から溶媒を除去することにより、沈殿した金属を含む導電性物体を形成する。【選択図】図１
