Abstract: An image recording method includes a step of applying a treatment liquid containing water and an aggregating agent to a permeable substrate to be transported, with a coating roller, and a step of applying an ink containing water, a water-soluble organic solvent, a colorant, and a resin to a region of the permeable substrate, which has been coated with the treatment liquid, by an ink jet method to record an image, in which, in a case where a diameter of the coating roller, expressed in mm unit, is defined as y and a viscosity of the treatment liquid at 25° C., expressed in mPa·s unit, is defined as x, x is 5 to 100 and a value of y?25ln(x) is 90 to 160.

Abstract: Provided are an ink set for a permeable substrate containing an ink for an ink jet and a treatment liquid, in which the ink for an ink jet contains water, a water-soluble organic solvent, a pigment, a pigment dispersion resin, and a resin component (X) which is at least one of a water-soluble resin or resin particles, and the treatment liquid contains water, a water-soluble organic solvent, and an organic acid salt having a molecular weight of 130 or less; and an image recording method.

Abstract: The invention provides: an ink composition, a method of producing the ink composition, and an image forming method using the ink composition. The ink composition includes: a urethane resin that includes an alicyclic structure at a content of from 6,000 mmol/kg to 12,000 mmol/kg; a water-soluble organic solvent; water; and a colorant.

Abstract: An ink set for inkjet recording includes: an ink composition including a pigment, a water-soluble polymerizable compound, and water; and a maintenance liquid that has a pH higher than 8.5 and that includes water and a water-soluble organic solvent having an SP value higher than 27.5 MPa1/2, the amount of water contained in the maintenance liquid being 50% by mass or more with respect to the total amount of the maintenance liquid, the amount of water-soluble organic solvent contained in the maintenance liquid having an SP value higher than 27.5 MPa1/2 being from 5 to 30% by mass with respect to the total amount of the maintenance liquid, and the amount of water-soluble organic solvent contained in the maintenance liquid having an SP value of 27.5 MPa1/2 or lower being less than 5% by mass with respect to the total amount of the maintenance liquid.
