1. Field of the Invention
The present invention relates to a coloring composition for dyeing or textile printing, an ink for ink jet textile printing, a method of printing on fabric, and a dyed or printed fabric.
2. Description of the Related Art
In the related art, as a dye for dyeing fabric, for example, an acid dye, a reactive dye, a direct dye, or a disperse dye is used. As a dye for dyeing cellulose fibers such as cotton or viscose rayon, for example, a reactive dye, a direct dye, a sulfur dye, a vat dye, or a naphthol dye is known. As a dye for dyeing polyamide fibers such as silk, wool, or nylon, for example, an acid dye, an acid metal complex dye, an acid mordant dye, or a direct dye is known. Regarding ester fibers such as polyester fiber or cellulose ester fiber, it is known that a disperse dye or a pigment is used for dyeing. In addition, acrylic fibers are generally dyed with a cationic dye. However, some acrylic fibers are dyed with an acid dye.
As dyes, various color dyes can be used. In particular, for magenta, for example, JP4750981B and JP1999-029714A (JP-H11-029714A) describe monoazo dyes.
In addition, as an industrial dyeing method for dyeing fabric, for example, screen printing, roller printing, or transfer printing has been used until now. These methods are dyeing techniques in which a series of steps including, for example, a step of planning a design pattern, an engraving or plate-making step, a step of preparing a printing paste, and a step of preparing a textile are integrated.
On the other hand, ink jet textile printing in which an ink jet method capable of directly supplying a dye to fabric is used has been proposed. Ink jet textile printing has advantageous effects in that, unlike textile printing of the related art, it is not necessary to make a plate and an image having excellent tone characteristics can be rapidly formed. Therefore, there are merits in that, for example, the delivery time can be reduced, many kinds in small quantities can be produced, and a plate-making step is unnecessary. Further, in ink jet textile printing, only an amount of ink required for forming an image is used. Therefore, it can be said that ink jet textile printing is an image forming method having excellent environmental friendliness in that, for example, the amount of waste liquid is less than that in a method of the related art.
JP2939908B describes a method of, using ink jet textile printing, designing a pattern suitable for a three-dimensional shape of a garment and rapidly reproducing the design image on a textile without deterioration.
In addition, JP2002-348502A describes an example in which a xanthene dye is used in an ink jet textile printing method.
On the other hand, JP5451556B describes a xanthene compound which is substituted with an acylamino group. In JP5451556B, a coloring composition including this compound is applied to paper using an ink jet method to form an image, and the saturation, light fastness, and ozone fastness of the image are discussed.
However, the dyes described in JP4750981B and JP1999-029714A (JP-H11-029714A) are strongly reddish compared to magenta and are insufficient in vividness. On the other hand, a dye having a xanthene skeleton which is known as, for example, Acid Red 52 or Acid Red 289 exhibits a vivid magenta color, and fabric can be dyed with this dye with a high density. In JP2002-348502A, fabric is printed using Acid Red 289. However, this dye is insufficient in light fastness and wet fastness. In addition, in a case where wet fastness is insufficient in ink jet textile printing, there is a problem in that image bleeding occurs.
The xanthene compound described in JP5451556B which is substituted with an acylamino group has fastness to light and ozone. However, in JP5451556B, issues (in particular, light fastness) arising in a case where the xanthene compound is used for dyeing fabric are not discussed.
Therefore, a coloring composition for dyeing or textile printing, which has excellent fixing properties and with which dyed fabric having excellent performance such as light fastness or wet fastness can be obtained, is required. In particular, in a case where a fine image is printed, there is a problem in that image bleeding occurs in a printing step after a steam treatment step and a water washing step, and currently further improvement is required.
An object of the present invention is to provide a coloring composition for dyeing or textile printing having an excellent color, a high color optical density, reduced bleeding, and excellent light fastness. In addition, another object of the present invention is to provide an ink for ink jet textile printing including the above-described coloring composition for dyeing or textile printing, a method of printing on fabric, and a dyed or printed fabric.

[Coloring Composition for Dyeing or Textile Printing]
A coloring composition for dyeing or textile printing according to the present invention includes a compound represented by the following Formula (1), (2), or (X).
<Compound Represented by Formula (1), (2), or (X)>
First, the compound represented by Formula (1), (2), or (X) will be described.
In Formula (1) or (2), R3, R4, R8, R9, R12, R14, R17, and R19 each independently represent a hydrogen atom or a substituent, and R1, R5, R6, R10, R11, R15, R16, and R20 each independently represent a substituted or unsubstituted alkyl group.

DSO3M)4 Formula (X)
In Formula (X), D represents a residue obtained by removing four hydrogen atoms from the compound represented by Formula (1) or (2).
M represents a hydrogen atom or a counter cation. M's may be the same as or different from each other.
By using the coloring composition for dyeing or textile printing including the compound represented by Formula (1), (2), or (X), the light fastness of dyed fabric is improved. In addition, by using the coloring composition for textile printing including the compound represented by Formula (1), (2), or (X), image bleeding is prevented. The action mechanism for these phenomena is not clear but is thought to be as follows. In particular, in a case where a xanthene compound having hydrogen bonding properties is printed on polyamide, the effect becomes significant. Therefore, the dye and the fabric are strongly fixed to each other due to a hydrogen bond, and water fastness is improved.

As the alkyl group, an alkyl group having 1 to 6 carbon atoms is preferable, an alkyl group having 1 to 3 carbon atoms is more preferable, and a methyl group is still more preferable.
R1, R5, R6, R10, R11, R15, R16, and R20 represent an alkyl group, a material which is dyed with the coloring composition for textile printing including the compound represented by Formula (1) or (2) can exhibit a vivid magenta color.
In Formula (2), from the viewpoint of raw material availability and synthesis easiness, R12, R14, R17, and R19 each independently represent preferably a hydrogen atom, a substituted or unsubstituted alkyl group, a substituted or unsubstituted aryl group, a substituted or unsubstituted alkoxy group, a substituted or unsubstituted aryloxy group, a carboxyl group, or a halogen atom, more preferably a substituted or unsubstituted alkyl group, a substituted or unsubstituted aryl group, a substituted or unsubstituted alkoxy group, and still more preferably a substituted or unsubstituted alkyl group.

(Coloring Composition for Dyeing or Textile Printing, and Dyeing or Textile Printing Method)
The coloring composition for dyeing or textile printing according to the present invention is not limited in the form of use as long as it is a coloring composition for dyeing a fiber. A method of dyeing a fiber is roughly classified into a dip dyeing method and a textile printing method. Dip dyeing is a process of dipping fabric to be dyed or yarn to be dyed in a dye solution, which is obtained by dissolving or dispersing a dye in a solvent, such that the dye is uniformly adsorbed on a surface of a fiber, is diffused into the fiber, and is fixed on the fiber by bonding. Textile printing is a dyeing method of producing a dyed material having a pattern by applying a dye or a pigment to fabric to be dyed to form a pattern thereon and fixing the dye or pigment on the fabric, and an effect of forming a pattern using one color or multiple colors can be exhibited. Industrially, screen printing and roller printing in which a plate is used, transfer printing in which transfer paper is used, or ink jet textile printing in which a plate-making step is unnecessary is performed.
[[Coloring Composition for Dip Dyeing and Method using The Same]]
Dip dyeing includes: a step of dipping fabric or yarn in a dye solution such that a dye is fixed on the fabric or the yarn; a washing step of washing off a portion of the dye which is not fixed on the fiber; and a drying step. In a case where the coloring composition according to the present invention is used for dip dyeing, the coloring composition can be used in the form of a dye solution in which fabric can be dipped.

[[Coloring Composition for Screen Printing, Roller Printing, or Transfer Printing, and Textile Printing Method using The Same]]
In a case where the coloring composition according to the present invention is used for screen printing, roller printing, or transfer printing, the coloring composition is used in the form of a color paste which is printed on fabric through a plate or transfer paper.
The textile printing method according to the present invention includes at least the following steps (1) to (4):
(1) a step of to adjusting a color paste by adding the coloring composition according to the present invention to a solution including at least a polymer compound and water;
(2) a step of printing the color paste of (1) on fabric;
(3) a step of applying steam to the printed fabric; and
(4) a step of washing the printed fabric with water and drying the washed fabric.
The color paste is required to satisfy the following suitabilities: printing suitability for printing the color paste on a plate; and dyeing suitability for a printed material in fixing and water washing treatments.
Therefore, in order to impart the printing suitability and the dyeing suitability, the color paste may include not only a dye but also a paste, a solvent, dyeing auxiliaries, and the like. The paste is a medium of the coloring composition, and a water-soluble polymer is used. Examples of the water-soluble polymer include a well-known water-soluble polymer such as a starch, a seaweed, a natural gum, a cellulose derivative, sodium alginate, a protein material, a tannin material, or a lignin material. In addition, a well-known synthetic polymer such as a polyvinyl alcohol compound, a polyethylene oxide compound, an acrylic acid aqueous polymer, a styrene aqueous polymer, or a maleic anhydride aqueous polymer can also be used as the paste. For example, a paste for textile printing described in pp. 349 to 361 of “Dyeing Note” can also be used. In addition, the paste can be used in combination with a printing paste improving agent described in pp. 367 to 369 of “Dyeing Note”. A mixture of two or more kinds of pastes may be used. As the solvent, a water-soluble solvent is preferably used, and a solvent including at least water is most preferably used.
Examples of the dyeing auxiliaries include a color former such as an acid or an alkali, a dye solubilizer, a wetting agent, a moisture absorbent, a deep dyeing agent, an anti-reducing agent, a metal ion binding agent, a ultraviolet absorber, a dispersant, a resisting agent, a discharge agent, a preservative, an fungicide, an antioxidant, a migration inhibitor, a dye fixing agent, and a defoaming agent.
As the dyeing auxiliaries, well-known dyeing auxiliaries can be used, and examples thereof include a solubilizer and a solubilizing agent described in pp. 336 to 338 of “Dyeing Note”, a deep dyeing agent, a level dyeing agent, and a penetrant described in pp. 339 to 345 of “Dyeing Note”, a defoaming agent described in pp. 346 to 348 of “Dyeing Note”, a metal ion binding agent described in pp. 147 to 154 of “Dyeing Note”, a dispersant described in pp. 216 to 222 of “Dyeing Note”, a resisting agent described in pp. 370 to 374 of “Dyeing Note”, a discharge agent described in pp. 375 to 381 of “Dyeing Note”, a preservative and an fungicide described in pp. 362 to 363 of “Dyeing Note”, a migration inhibitor described in pp. 279 to 284 of “Dyeing Note”, a dye fixing agent described in pp. 426 to 429 of “Dyeing Note”, a wet fastness improving agent described in JP1994-166969A (JP-H06-166969A), and a light fastness improving agent described in U.S. Pat. No. 5,336,443A.
Dyeing auxiliaries are added to a paste solution obtained by dissolving or dispersing a paste in a solvent, a dye solution obtained by dissolving or dispersing a dye in a solvent is added to the paste solution, and the components are stirred. As a result, a color paste is prepared (a step of preparing a color paste).
In the textile printing method, unlike the dip dyeing method, after printing the color paste on fabric (a step of printing the color paste on fabric), a treatment of fixing the colorant, which is printed on the fabric, on the fiber. This treatment is called a color developing step, and a method using heated air or a method using normal pressure saturated steam or superheated steam can be performed for the treatment. In particular, a method using normal pressure saturated steam is preferable. In the present invention, a step of applying steam to the printed fabric is performed. In the step of applying steam to the printed fabric, the temperature and time in the steam treatment vary depending on the kind of the coloring composition and the kind of the fabric. For example, the temperature is preferably 100° C. to 108° C., and the time is preferably 1 to 60 minutes and more preferably 1 to 30 minutes. After the step of applying steam to the printed fabric, as in the case of dip dyeing, a washing step and a drying step are performed to obtain a printed material. It is preferable that the fabric includes polyamide.
[[Coloring Composition for Ink Jet Textile Printing and Method using The Same]]
In a case where the coloring composition according to the present invention is used for ink jet textile printing, the coloring composition is used in the form of an ink for ink jet textile printing. An ink jet textile printing method has advantageous effects in that, compared to a textile printing method of the related art, an image having excellent tone characteristics can be rapidly formed. Therefore, there are merits in that, for example, the delivery time can be reduced, many kinds in small quantities can be produced, and a plate-making step is unnecessary. Further, in ink jet textile printing, only an amount of ink required for forming an image is used. Therefore, it can be said that ink jet textile printing is an image forming method having excellent environmental friendliness in that, for example, the amount of waste liquid is less than that in a method of the related art.
The ink for ink jet textile printing causes nozzle clogging of an ink jet head in a case where the viscosity thereof increases due to evaporation of water, an aqueous organic solvent, or the like from a nozzle tip or a case where a dye as a solid component is deposited. Therefore, it is required that the ink for ink jet textile printing has more satisfactory color developing properties than that used in textile printing of the related art. In addition, it is required that ink suitability such as ink storage stability or jetting stability, dyeing suitability such as bleeding prevention or contamination prevention, and image fastness such as light fastness, water fastness, or washing fastness are also imparted to the ink for ink jet textile printing.
An ink jet textile printing method according to the present invention includes at least the following steps (11) to (14):
(11) a step of applying a paste including at least a polymer compound and water to fabric;
(12) a step of printing the coloring composition according to the present invention on the fabric using an ink jet method;
(13) a step of applying steam to the printed fabric; and
(14) a step of washing the printed fabric with water and drying the washed fabric.
In a case where a color paste used in a textile printing method of the related art is used in the ink jet textile printing method, nozzle clogging occurs. Therefore, in the ink jet textile printing method, a pre-treatment step of applying a paste to fabric in advance (the step of applying a paste including at least a polymer compound and water to fabric) is necessary. By performing the pre-treatment step, fabric handleability is improved. Specifically, pre-treated fabric is obtained by applying a paste solution including a paste, a solvent, and a hydrotropy agent to fabric and drying the fabric. It is preferable that the fabric includes polyamide.
As the paste, the same paste as that used for screen printing or the like can be used. As the solvent, a water-soluble solvent is preferably used, and a solvent including at least water is most preferably used.
In general, the hydrotropy agent serves to increase the color optical density of an image when fabric to which an ink composition is applied is heated by steam. For example, typically, urea, alkyl urea, ethylene urea, propylene urea, thiourea, guanidine hydrochloride, or tetraalkyl ammonium halide is used. In addition, a well-known hydrotropy agent can be used, and examples thereof include a dye fixing agent described in pp. 426 to 429 of “Dyeing Note”. The content of the hydrotropy agent is preferably 0.01 mass % to 20 mass % with respect to the total solid content of the paste solution.
Optionally, the paste solution further includes, for example, a pH adjuster, an aqueous (water-soluble) metal salt, a water repellant, a surfactant, a migration inhibitor, or a micropore forming agent. As these additives, well-known additives can be used, and examples thereof include a solubilizer and a solubilizing agent described in pp. 336 to 338 of “Dyeing Note”, a deep dyeing agent, a level dyeing agent, and a penetrant described in pp. 339 to 345 of “Dyeing Note”, a metal ion binding agent described in pp. 147 to 154 of “Dyeing Note”, a resisting agent described in pp. 370 to 374 of “Dyeing Note”, a discharge agent described in pp. 375 to 381 of “Dyeing Note”, a preservative and an fungicide described in pp. 362 to 363 of “Dyeing Note”, a migration inhibitor described in pp. 279 to 284 of “Dyeing Note”, a micropore forming agent described in JP1995-316991A (JP-H07-316991A), a wet fastness improving agent described in JP1994-166969A (JP-H06-166969A), and a light fastness improving agent described in U.S. Pat. No. 5,336,443A. In addition, an additive described in paragraphs “0096” to “0101” of JP2013-209786A can also be used.
In the pre-treatment, the paste solution is padded at an squeezing rate of 5% to 150% and preferably 10% to 130%.
In the pre-treatment, a method of applying the respective paste solutions to fabric is not particularly limited, and examples thereof include methods which are typically performed, for example, a padding method, a coating method, a screening method, a spraying method, a transfer method, and an ink jet method.
Next, the pre-treated fabric is printed using the ink for ink jet textile printing.
The ink for ink jet textile printing can be prepared by dissolving and/or dispersing the compound (mixture) represented by Formula (1), (2), or (X) in a solvent.
The solvent is determined based on, for example, the kind of the substituent used in Formula (1), (2), or (X), the kind of the solvent component used for producing the coloring composition, and the kind of fabric to be dyed. It is preferable that water or a water-soluble organic solvent is used.

Examples of the cationic surfactant include an aliphatic amine salt and an aliphatic quaternary ammonium salt. Examples of the anionic surfactant include a fatty acid soap and a N-acyl-N-methylglycine salt. Examples of the amphoteric surfactant include carboxy betaine, sulfo betaine, aminocarboxylate, and imidazolinium betaine.

In the case of a water-soluble ink, these various additives are directly added to the ink solution. In a case where an oil-soluble dye is used in the form of a dispersion, in general, the additives are added to a dye dispersion after the preparation of the dispersion. However, the additives may be added in the form of an oil phase or an aqueous phase during the preparation. In a case where an oil-soluble dye is used in the form of a dispersion, a dispersant can be used. As the dispersant, for example, a dispersant described in pp. 216 to 222 of “Dyeing Note” can be used.
As the anti-drying agent, the anti-fading agent, the ultraviolet absorber, the fungicide, the pH adjuster, the surface tension adjuster, the defoaming agent, and the chelating agent, those described in paragraphs “0224” to “0231” of JP2014-5462A can be used. In addition, the ink for ink jet textile printing according to the present invention may also include a wet fastness improving agent described in JP1994-166969A (JP-H06-166969A) and a light fastness improving agent described in U.S. Pat. No. 5,336,443A.
The penetration enhancer is used in order to enhance the penetration of the ink for ink jet textile printing into the fiber and the fixing of the ink thereon. As the penetration enhancer, a well-known additive can be used. For example, a wetting agent, a penetrant, a level dyeing agent, a retarding agent, and an alcohol such as ethanol, isopropanol, butanol, di(tri)ethylene glycol monobutyl ether, or 1,2-hexanediol described in pp. 223 to 255 of “Dyeing Note”; sodium lauryl sulfate, sodium oleate, a nonionic surfactant; or a branched polyhydric alcohol described in WO10/109867A or JP1994-57644A (JP-H06-57644A) can be used. Typically, these penetration enhancers function in a case where the addition thereof is 5 to 35 mass %. It is preferable that the penetration enhancer is used in an addition amount range where bleeding does not occur after dyeing and where ink leakage from a back surface does not occur.
In a case where the compound according to the present invention is dispersed in an aqueous medium, the compound can be dispersed using a method described in paragraphs “0232” to “0233” of JP2014-5462A.
In the present invention, the content of the compound represented by Formula (1), (2), or (X) in the coloring composition is determined based on, for example, the kind of the substituent used in Formula (1), (2), or (X), and the kind of the solvent component used for producing the coloring composition.

As the dye, a dye described in paragraphs “0237” to “0240” of JP2014-5462A can be used.
The ink for ink jet textile printing according to the present invention can be used as any one of various color inks but is preferably used as a magenta ink.
After drying, fabric which is printed using an ink jet method undergoes the color developing step, the washing step, and the drying step to obtain a printed material as in the case of other textile printing methods. A preferable method for performing the color developing step to the drying step is the same as in screen printing or the like.

Using a spectrodensitometer(“X-rite 938”, manufactured by X-rite Inc.), the CMYK density of the dyed fabric was measured under conditions of a density filter (ISO status A), density white base (absolute white base), no polarization filter, and an observer angle of 2° such that the reflection density of magenta (M) was measured as OD-Magenta.
3. Light Fastness Evaluation
Using Xenon Fade-OMeter, dyed samples prepared according to ISO 105-B02 were irradiated with xenon light for 6 hours.
Before and after the irradiation of the xenon light, the lightness value L* and the chroma values a* and b* of each of the samples in the CIE L*a*b* color space (International Commission on illumination (1976)/JIS Z8781-4:2013) were measured using spectrodensitometer (“X-rite 938”, manufactured by X-rite Inc.), and ΔEab as a color difference between two samples was obtained based on ΔL*, Δa*, and Δb* which were differences between coordinate values L*, a*, and b* in the L*a*b* color space. A lower value represents that the behavior before and after the light irradiation is small and excellent.
Color Difference ΔEab=(ΔL*2+Δa*2+Δb*2)0.5
