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, 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.

Pattern forming method

An active light beam-curable inkjet magenta ink, wherein the ink comprises at least a pigment, a polymer dispersing agent, a crystalline gelling agent, a photopolymerizable compound and a photopolymerization initiator, the pigment is a solid-solution of PV19 and PR202 which has been subjected to surface treatments with alumina and sulfonic acid, the impart amount of the alumina with respect to the pigment is from 1,500 to 7,500 ppm by mass ratio, and the content of the crystalline gelling agent is from 1.5 to 3.0% by mass with respect to the entirety of the ink has fine storage stability and pinning property, and has a small gloss difference from other colors.
