Problems solved by technology

[0010] However, the pigment is attached (attached) to the fiber in the form of particles in which the molecules of the pigment are aggregated, and in order to maintain the fastness of the colored cloth (colored cloth) to washing, fastness to friction, etc., it is necessary to use A large amount of emulsion resin is used as a fixing agent, and the handle of the colored cloth becomes hard. For example, in the case where the colored cloth is a garment, the quality of the garment as a dyed dyed cloth is poor.
Moreover, it is easy to cause the drying of the emulsion resin, the thickening of the pigment ink, and the clogging of the inkjet printer due to the volatilization of water, and the operability is poor.

Synthetic example 1

[0561] [Synthesis of Dye Polymer (Y-1-1)]

[0562] Exemplary compound (Y-1-1) was synthesized by the following scheme.

[0563] [chemical formula 65]

[0564]

[0565] 10 mL of N-methylpyrrolidone (NMP) was added to a 100 mL three-necked flask, and the internal temperature was raised to 85°C. To the above NMP, 9.0 g of the polymerizable monomer YM-1 (synthesized by the method described in Japanese Patent No. 5315267 ), 1.0 g of the polymerizable monomer MOI-BP ( Manufactured by Showa Denko K.K., trade name: Karenz MOI-BP), 0.98 g of V-601 (manufactured by Wako Pure Chemical Industries, Ltd., trade name) and 0.35 g of 1-dodecanethiol were dissolved in 13.24 g of NMP The resulting solution. After completion|finish of dripping, it was made to react at 85 degreeC for 1 hour, and the reaction liquid A was obtained. Then, V-601 (0.098g) was added to the reaction liquid A, and it was made to react at 85 degreeC for 2 hours, and the reaction liquid B was obtained. The reaction s...

[0567] [Synthesis of Dye Polymer (Y-2-1)]

[0568] Exemplary compound (Y-2-1) was synthesized by the following scheme.

[0569] [chemical formula 66]

[0570]

[0571] Regarding the exemplary compound (Y-2-1), the MOI-BP (manufactured by Showa Denko K.K., trade name: Karenz MOI-BP) used in the synthesis of the exemplary compound (Y-1-1) of the above synthesis example 1 Change to methacrylic acid (MAA), and change the amount of V-601 (manufactured by Wako Pure Chemical Industries, Ltd., trade name) in the solution dropwise with the polymerizable monomer from 0.98 g to 0.126 g, and It synthesized in the same manner except having changed the quantity of 1-dodecanethiol from 0.35 g to 0.443 g. The maximum absorption wavelength of the ultraviolet-visible absorption spectrum of the exemplary compound (Y-2-1) in tetrahydrofuran (THF) dilute solution is 441 nm. And, the weight average molecular weight (Mw) by GPC measurement was 10,500 (polystyrene conversion). The Tg of the po...

[0573] [Synthesis of Dye Polymer (R-2-1)]

[0574] Exemplary compound (R-2-1) was synthesized by the following scheme.

[0575] [chemical formula 67]

[0576]

[0577] Regarding the exemplary compound (R-2-1), YM-1 used in the synthesis of the exemplary compound (Y-1-1) in Synthesis Example 1 above was changed to RDW R-13 (Wako Pure Chemical Industries, Ltd. manufactured, trade name), and MOI-BP (manufactured by Showa Denko K.K., trade name: Karenz MOI-BP) was changed to 2-ethylhexyl methacrylate (EHMA), and the polymerizable monomer was added dropwise The amount of V-601 (manufactured by Wako Pure Chemical Industries, Ltd., trade name) in the solution was changed from 0.98 g to 0.057 g, and the amount of 1-dodecanethiol was changed from 0.35 g to 0.200 g, and It synthesized in the same manner except having changed NMP into propylene glycol-1-monomethyl ether-2-acetate (PGMEA). The maximum absorption wavelength of the ultraviolet-visible absorption spectrum of the exempl...

Abstract

The present invention provides: an inkjet printing method having a step in which inkjet ink is directly printed onto fabric using an inkjet scheme, the inkjet ink containing an aqueous dispersion of adye polymer having repeating units that contain a structure derived from a dye; an inkjet ink containing the aqueous dispersion of a dye polymer; an ink cartridge filled with the inkjet ink; and a colored fabric.

Description

technical field [0001] The invention relates to an inkjet printing method, an inkjet ink, an ink box and a colored cloth. Background technique [0002] Conventionally, the coloring agent used for coloring fabrics is any one of dyes and pigments. As a method of industrially coloring fabrics using these colorants, screen printing, roll printing, transfer printing, Inkjet method, etc. In particular, the inkjet method can be said to be an excellent image forming method: Compared with other methods, it can quickly form an image with excellent gradation without making a plate, and, as forming an image, only the required amount of ink is used, so the waste liquid is less. It is environmentally advantageous to wait less. [0003] For example, Patent Document 1 describes inkjet printing in which an ink is prepared by dissolving a dye in water, and fabric is dyed by an inkjet method. [0004] The dye enters the interior of the fiber and becomes integrated with the fiber through the...
