preparation example Construction

[0130]The method for preparing the ink for inkjet recording of the present invention is not particularly limited, but it is preferably prepared by the following method. That is, first, (a) each dye used in the above-mentioned orange disperse dye, the above-mentioned first to fourth disperse dye compositions, and the first and second disperse dye compositions for mixing, a dispersant, water, and if necessary And the added water solvent, organic solvent or the above-mentioned additives are mixed and stirred to prepare a pre-dispersion liquid. Next, (b) disperse the above-mentioned pre-dispersion liquid using a wet media mill such as a sand mill to obtain a dispersion liquid of each of the above-mentioned dyes. (c) When preparing the ink of only the above-mentioned orange disperse dye, water, a water-soluble organic solvent, and the above-mentioned additives added as needed can be added to the above-mentioned dispersion liquid to adjust the concentration, and then filtered throug...

Embodiment 1

[0138] (Example 1) [synthesis of orange disperse dye [1-1]]

[0139] A mixture of N-cyanoethyl-N-hydroxyethylaniline (18.7 parts) and β-picoline (10.9 parts) was warmed to 50°C. Then, benzoyl chloride (16.8 parts) was added dropwise to the above mixture within 3 hours at 60-70° C., and then kept at the same temperature for 1 hour to obtain N-cyanoethyl-N-benzoyloxy Ethylaniline. Sulfamic acid (2 parts) was added to the mixture, and 120 parts of acetic acid was added to dissolve it, and then ice was added to adjust the mixture to 5-10°C to obtain a coupling agent solution.

[0140] Slowly add 2-cyano-3-chloro-5- Nitro-1-trifluoromethylbenzene (24 parts). By keeping the above mixture at 5-10°C for 4 hours, a diazo compound was obtained.

[0141] Ice was properly added to the above coupling agent solution to keep the temperature at 5-10°C, and at the same time, the above diazo compound solution was added dropwise within 3 hours to carry out the coupling reaction.

Embodiment 2

[0144] (Example 2) [synthesis of orange disperse dye [1-2]]

[0145] Using 2-cyano-3-bromo-5-nitro-1-trifluoromethylbenzene (28.5 parts) instead of 2-cyano-3-chloro-5-nitro-1-trifluoromethylbenzene, And use N-cyanoethyl-N-cyanoethoxyethylaniline to replace N-cyanoethyl-N-benzoyloxyethylaniline, except that, according to the same as in Example 1 The dyestuff represented by the following formula [1-2] is obtained by the method. In addition, N-cyanoethyl-N-cyanoethoxyethylaniline was produced as follows. The mixture of N-cyanoethyl-N-hydroxyethylaniline (18.7 parts) and acrylonitrile (14.9 parts) was heated to 80-90°C and kept at the same temperature for 2 hours to obtain N-cyanoethyl -N-cyanoethoxyethylaniline.

[0146] The obtained following formula [1-2] represents the maximum absorption wavelength (λ max ) is 429nm.

Abstract

Disclosed are: a novel orange-colored disperse dye which has excellent staining properties onto a hydrophobic fiber material, a high light-resistant color-fastness, an excellent sublimation fastness, and a good buildup property, and is useful as a dye for use in an automotive interior sheet; a disperse dye composition for yellow-to-orange, brown, dark blue and black colors which comprises the disperse dye; an ink for ink-jet printing; a staining method or a stained material using the disperse die, the composition or the ink. The orange-colored disperse dye is represented by the formula (1) below and can stain a hydrophobic fiber material (e.g., a polyester) into orange color. [Chemical formula] (1) wherein X1 represents a chlorine or bromine atom; R1 represents a benzoyl group, a cyanoethyl group, a C1-C4 alkyl group, a phenyl group or a phenyl group substituted by at least one C1-C4 alkyl group.

Description

technical field [0001] The present invention relates to a novel orange disperse dye which is excellent in dyeing performance, high light fastness, sublimation fastness and good dyeing performance of a hydrophobic fiber material, which can be used especially as a sheet for automobile interior decoration, Disperse dye composition, ink for inkjet printing and dyeing, dyeing method and dyed product using them. Background technique [0002] In recent years, hydrophobic fiber materials have been used for automotive interiors, especially as materials for seat sheets, and polyester-based fibers in particular have been widely used. In addition, with the increase in fashion in recent years, it is required to have rich colors. However, when used as an automotive interior sheet, the yellow color fades and discolors due to prolonged high-temperature exposure, which causes discoloration of mixed dyes with red and blue. [0003] Commonly used lightfastness evaluation methods include the ...
