摘要： Provided are an image recorded material having excellent lamination strength in a case where a base material for lamination is laminated on an image and a method of producing the same, and a laminate and a method of producing the same. The method of producing an image recorded material is a method including an image recording step of sequentially applying a pretreatment liquid containing an aggregating agent and water, a first ink containing a first pigment, a first resin, and water, and a second ink containing a second pigment, a second resin, and water and having a surface tension less than a surface tension of the first ink onto an impermeable base material to record an image, in which in the image recording step, the image is recorded under a condition in which a ratio of a total applied mass of the first resin and the second resin per unit area to an applied mass of the aggregating agent per unit area in an overlapping region formed such that a region where the pretreatment liquid is applied, a region where the first ink is applied, and a region where the second ink is applied overlap each other in plan view is generated is 16.0 or greater and 30.0 or less.

摘要： Provided are an inkjet ink composition and applications thereof, in which both rub resistance of an image recorded on an impermeable base material and removability of the inkjet ink composition from a nozzle surface of an ink jet head are achieved. The inkjet ink composition is an inkjet ink composition including water (A), a resin (B), and an organic solvent (C) which has a boiling point of 250°C or lower, satisfies Expression (CI), and has a nitrogen atom, in which a content mass ratio of the organic solvent (C) to a main resin in the resin (B) is 0.01 or greater and less than 2.0. In Expression (C1), SP B represents an SP value of the main resin in the resin (B) in a unit of MPa 1/2 , SP C represents an SP value of the organic solvent (C) in the unit of MPa 1/2 , and |SP C - SP B | represents an absolute value of a difference between SP C and SP B . SP C − SP B ≤ 10.0
