Japanese Patent JP7332265
Kind Code:
B2
Abstract:
To provide black dispersion liquid for inkjet printing ink that can manufacture a dyed thing excellent in color rendering, can obtain high quality dyed thing that can obtain high concentration dyed thing, and has excellent redispersion.SOLUTION: A colorant dispersion comprises (A) a compound expressed by a formula (1), and (B) polyoxyethylene arylphenyl ether-based dispersant and polyoxyethylene arylphenyl ether sulfate-based dispersant. (R1 is H or a nitro group; R2 and R3 are independently C1 to C4 alkoxy group or C1 to C4 alkyl group that may be substituted with a phenyl group; R4 is halogen atom; and R2 and R3 may be mutually coupled to form a ring.)SELECTED DRAWING: None
