-
, (2021/08/13)
PROBLEM TO BE SOLVED: To provide dispersion liquid for inkjet printing ink that can manufacture a dyed thing excellent in color rendering, can obtain the dyeing having high sublimation transfer efficiency, high concentration and high quality, in sublimation transfer dying using inkjet printing, furthermore, excellent in storage stability. SOLUTION: A colorant dispersion comprises (A) a compound expressed by a formula (1), (B) C.I. Disperse Blue 360, and (C) a dispersant, in which when a total content of (A) and (B) is set to 100, a content of (B) is 10 or larger and 90 or smaller, (C) the dispersant contains at least any one selected from the group consisting of polyoxyethylene aryl phenyl ether-based dispersant, and polyoxyethylene arylphenyl ether sulfate-based dispersant. (R1 is H or a nitro group; R2 and R3 may be independently substituted with C1-C4 alkoxy group or C1-C4 alkyl groups that may be substituted with phenyl group; R4 is halogen atom; and R2 and R3 may be mutually coupling to form a ring.)
