Definitions
- the present invention relates to a colored dispersion.

- a water-insoluble colorant is dispersed in water and which has good performance such as dispersion stability.
- the inkjet textile printing method for hydrophobic fibers is roughly divided into the direct printing method and the sublimation transfer method.
- the direct printing method is a textile printing method in which ink is directly applied (printed) to hydrophobic fibers, and then the hydrophobic fibers are dyed with the dye in the ink by heat treatment such as high-temperature steaming.
- the sublimation transfer method ink is applied (printed) to an intermediate recording medium (dedicated transfer paper, etc.), then the ink-applied surface of the intermediate recording medium and hydrophobic fibers are superimposed, and then the dye is transferred to the intermediate by heat. It is a printing method that transfers from a recording medium to a hydrophobic fiber.
- the sublimation transfer method is mainly used for printing banners, etc., and easily sublimation dyes are used in the ink, which are excellent in transferability to hydrophobic fibers by heat treatment.
