摘要： An object is to achieve an ink composition for aqueous inkjet textile printing excellent in nozzle plate liquid repellency, contamination protection of a nozzle plate, and discharge property, as well as both sufficient image density and fastness to washing. As a solution, an ink composition for aqueous inkjet textile printing is provided that includes a pigment, a water-dispersible resin, a surfactant, a crosslinking agent, and water, wherein as the surfactant, a nonionic surfactant having a hydrophilic-lipophilic balance (HLB) of 1.0 to 5.0 is contained by 0.1 to 3.0% by mass relative to a total amount of the ink composition, and as the crosslinking agent, a blocked isocyanate by 0.1 to 5.0% by mass is contained relative to the total amount of the ink composition.

摘要： An object of the present invention is to obtain an active energy ray-curable inkjet ink composition designed to improve color development property and to be LED curable, and designed so that a cured coating film has high hardness and excellent rub resistance and water resistance. As a solution, the ink composition contains a pigment, a pigment dispersant, and a photopolymerizable compound, wherein the pigment contains Pigment Violet 19 and Pigment Orange 71, and Pigment Violet 19 is 30.0 to 85.0% by mass relative to a total mass of Pigment Violet 19 and Pigment Orange 71, and the photopolymerizable compound satisfies all of the following requirements (A) to (F): (A) a multifunctional amine-modified oligomer is contained by 0.20 to 15.0% by mass in a total amount of all polymerizable components; (B) a monofunctional monomer is contained by 50.0% by mass or more in the total amount of all polymerizable components; (C) a monofunctional monomer whose glass transition temperature is 20°C or more is contained by 35.0% by mass or more in the total amount of all polymerizable components; (D) a monofunctional monomer whose glass transition temperature is 10°C or less is contained by 35.0% by mass or more in the total amount of all polymerizable components; (E) a multifunctional monomer whose glass transition temperature is 10°C or less is contained by 2.0 to 11.0% by mass in the total amount of all polymerizable components; and (F) a nitrogen-containing monofunctional monomer is contained by 10.0 to 25.0% by mass in the total amount of all polymerizable components.

摘要： Provided are an image recording method that enables recording of an image with an excellent covering property and excellent lamination strength with a base material for lamination, and applications thereof. The image recording method is an image recording method including a step of preparing a white ink that contains a white pigment, a first organic solvent having a boiling point of 120°C or higher, and water, a step of preparing a colored ink that contains a colored pigment other than the white pigment, a second organic solvent having a boiling point of 120°C or higher, and water, and a step of recording an image by applying each of the white ink and the colored ink onto an impermeable base material, in which an image is recorded in the step of recording an image under conditions that a total mass of the first organic solvent and the second organic solvent to be applied per unit area is 5.5 g/m 2 or less, and a mass of the white pigment to be applied per unit area is 0.4 g/m 2 or greater in a region where a region to which the white ink is applied and a region to which the colored ink is applied overlap each other in plan view.
