Abstract: An image recording method includes: preparing a white ink that contains a white pigment, a first organic solvent having a boiling point of 120° C. or higher, and water; 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 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 under conditions that a total mass of the first organic solvent and the second organic solvent is 5.5 g/m2 or less, and a mass of the white pigment is 0.4 g/m2 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.

Abstract: Provided are a colored resin particle dispersion containing colored resin particles and water, in which the colored resin particles contain a water-insoluble chain polymer and at least one dye selected from the group consisting of an oil-soluble dye, a disperse dye and a vat dye, and the water-insoluble chain polymer has a structure represented by the following General Formula (G), a cyclic structure, and a hydrophilic group, an ink manufactured using the colored resin particle dispersion, an ink set having the ink, an inkjet printing method using the ink, and a method of manufacturing the colored resin particle dispersion. In the General Formula (G), Rg represents a hydrogen atom or a substituent, Lg represents —O—, —S—, or —NRz-, Rz represents a hydrogen atom or a substituent, and * represents a bonding position.
