  • Patent number: 11800648
    Abstract: A pattern forming method capable of easily removing a discontinuous portion in a pattern while keeping resistance of the pattern low. A pattern forming method including at least a printing step of printing a pattern intermediate containing a conductive material on a base material 1, and a plating step of subjecting the pattern intermediate to an electroplating treatment, in which the pattern intermediate printed in the printing step has a plating target portion that is energized in the plating step and a discontinuous portion that is discontinuously formed from the plating target portion and is not energized in the plating step, and in the plating step, by performing an electric field plating treatment using a plating solution containing at least two or more types of metal salts containing different types of metals and a complexing agent, the discontinuous portion of the pattern intermediate is removed to form a pattern constituted by the plating target portion covered with a plating film.

  • Publication number: 20210329789
    Abstract: An object of the present invention is to provide a method for forming a conductive thin wire, the method being capable of improving thin wire formability, conductivity, adhesion, and transmittance of a conductive thin wire, a method for producing a transparent conductor, a method for producing a device, and a set of a conductive ink and a base material. This object is achieved by a method for forming a conductive thin wire on a base material by an inkjet method using a conductive ink containing at least a main solvent having a boiling point equal to or lower than the boiling point of water, a solvent having a boiling point higher than that of water, and a conductive material, in which the base material has surface energy of less than 40 mN/m, and conditions of 30°??1?70°, 0°??2?40°, and ?2??1 are satisfied when a forward contact angle of the conductive ink to the base material is represented by ?1, and a backward contact angle of the conductive ink to the base material is represented by ?2.
