Colored resin particle dispersion, ink, ink set, inkjet printing method, and method of manufacturing colored resin particle dispersion

A method of manufacturing a colored resin particle dispersion containing colored resin particles and water,

• the colored resin particles containing 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,
• the water-insoluble chain polymer having a structure represented by the following General Formula (G), a cyclic structure, and a hydrophilic group, and
• the method comprising:
• a step (1);
• and
• a step (2),
• wherein the step (1) is a step of obtaining an emulsion by emulsifying a mixture containing water, an organic solvent, a water-insoluble chain polymer having a structure represented by the General Formula (G), a cyclic structure and a hydrophilic group, and at least one dye selected from the group consisting of an oil-soluble dye, a disperse dye and a vat dye,
• the step (2) is a step of removing the organic solvent from the emulsion obtained in the step (1), and
• a mass ratio of a content of the water-insoluble chain polymer to a content of the dye in the mixture of the step (1) is 0.1 to 2.5,
• 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.
