  • Publication number: 20220204786
    Abstract: A colored dispersion that contains (A) a dye derivative, (B) a water-insoluble dye, (C) a dispersant, and water. The (A) component contains an anthraquinone-based compound represented by formula (al), the (C) component does not contain a polyoxyethylene aryl phenyl ether and a polyoxyethylene aryl phenyl ether sulfate at the same time, and the mass ratio ((B)/(A)) of the (B) component with respect to the (A) component satisfies the relationship 400>(B)/(A)>3.125. A recording medium having the colored dispersion adhered thereto and a hydrophobic fiber printing method using the colored dispersion. In formula (a1), each of Ra1-Ra5 is a hydrogen atom, and Xa1 is a group represented by formula (a4).
