Technical Field
[0001] This invention relates to a composition and an inkjet printing recording method. Background Technology
[0002] Inkjet printing is not only suitable for recording images on paper and other materials, but also for printing and dyeing fabrics. In particular, various studies have been conducted in inkjet printing and dyeing using pigments to improve the color development and rubbing fastness of images printed on fabrics.
[0003] For example, in Patent Document 1, in order to improve the friction fastness of printed and dyed materials, an inkjet printing ink using a urethane resin with a film elongation of 600% to 2000% is disclosed.
[0004] In addition, white inkjet ink compositions (hereinafter also referred to as "white ink") are sometimes used as the base for images printed on fabric. To improve the color development and rubbing fastness of the image, white ink sometimes contains more white pigment and resin.

[0028] 1. Composition group
[0029] One embodiment of the present invention includes a printing inkjet ink composition and a processing liquid composition. The composition group of this embodiment may further include a non-white inkjet ink composition.
[0030] The composition group involved in this embodiment is any composition used in the recording process of the inkjet ink composition and the processing liquid composition, and is not limited to those manufactured and sold in an integrated state. It is included in the group when the inkjet ink composition and the processing liquid composition are used together, or when their use is substantially induced.
[0031] Hereinafter, the compositions included in the composition group according to this embodiment will be described.
[0032] 1.1. Printing and dyeing inkjet ink composition
[0033] The inkjet ink composition involved in this embodiment contains white pigment, resin particles and water.
[0034] The components contained in the inkjet ink composition for printing and dyeing according to this embodiment will be described in detail below.
[0035] 1.1.1. White pigment
[0036] The inkjet ink composition according to this embodiment includes a white pigment. Examples of white pigments include metal oxides, barium sulfate, calcium carbonate, and other metal compounds. Examples of metal oxides include titanium dioxide, zinc oxide, silicon dioxide, aluminum oxide, and magnesium oxide. Alternatively, particles with a hollow structure can be used as the white pigment. Known particles can be used as the particles with a hollow structure.
[0037] Examples of white pigments include CI pigments 1, 4, 5, 6, 6:1, 7, 18, 19, 20, 21, 22, 26, 27, and 28.
[0038] The content of white pigment relative to the total amount of the inkjet ink composition is preferably 7.0% by mass or more, more preferably 7.5% by mass or more, even more preferably 8.0% by mass or more, and particularly preferably 8.3% by mass or more. If the content of white pigment is within the above range, the opacity of the substrate is improved and the white color development becomes better when using the white ink composition as a base for a non-white ink composition. Furthermore, the content of white pigment is preferably 13.0% by mass or less, more preferably 12.0% by mass or less, and even more preferably 11.8% by mass or less. If the content of white pigment is within the above range or less, the rubbing fastness of the printed material becomes better, and the stability of continuous printing during printing is improved.
[0039] White pigments can also be dispersed in a dispersion medium using pigment dispersants. Examples of pigment dispersants include resin dispersants, which can be selected from those that provide good dispersion stability of the pigment in the ink composition. Alternatively, pigments can be used as self-dispersing pigments by modifying the surface of pigment particles through oxidation or sulfonation using, for example, ozone, hypochlorous acid, or fuming sulfuric acid.
[0040] 1.1.2. Resin particles
[0041] The inkjet ink composition involved in this embodiment contains resin particles.
[0042] White ink compositions tend to exhibit decreased rubbing fastness as the pigment content increases. To achieve good rubbing fastness, it is preferable to increase the resin particle content while simultaneously increasing the pigment content.
[0043] The content of resin particles (w2) relative to the content of white pigment (w1) in a mass ratio (w2 / w1) is preferably 0.5 or more, more preferably 0.6 or more, and even more preferably 0.7 or more. If the mass ratio of resin particle content to white pigment content is within the above range, the content of resin particles relative to white pigment content is sufficient, and the rubbing fastness of the printed material becomes good. Furthermore, the above-mentioned mass ratio is preferably 1.5 or less, more preferably 1.4 or less, and even more preferably 1.3 or less.
[0044] The content of resin particles relative to the total amount of the inkjet ink composition is preferably 6.5% by mass or more, more preferably 7.0% by mass or more, and even more preferably 7.5% by mass or more. If the resin content is within the above range or higher, the printed material retains its hand feel and exhibits good rubbing fastness. If the resin content is too high, the hand feel of the printed material tends to decrease; therefore, it is preferably 11.5% by mass or less, more preferably 10.5% by mass or less, and even more preferably 10.0% by mass or less. If the resin content is within the above range or lower, the viscosity of the ink composition becomes preferable, and the stability of continuous printing during printing is improved. Furthermore, a good hand feel is achieved.
[0045] It should be noted that, as resin particles, when there are both resin particles with an elongation at break of 400% or more and 1000% or less and resin particles with an elongation at break of not more than 400% or more and 1000% or less, the total content should be 6.5% by mass or more. However, the content of resin particles with an elongation at break of 400% or more and 1000% or less is preferably 6.5% by mass or more.
[0046] The elongation at break of the resin particles also affects the hand feel of printed materials using the inkjet printing composition. The elongation at break of the resin particles can be determined by tensile testing using a test piece in which the resin particles are formed into a film, as described later. If the elongation at break of the resin particles is high, the coating film of the ink composition can follow the stretching and contraction of the fabric as the recording medium, thus not impairing the hand feel of the printed material.
[0047] Therefore, the inkjet printing composition according to this embodiment contains resin particles with an elongation at break of 400% or more, preferably 500% or more, more preferably 650% or more, and particularly preferably 670% or more. By including resin particles exhibiting an elongation at break within the above-mentioned range, the inkjet printing composition according to this embodiment can produce printed materials that maintain a good hand feel while also exhibiting excellent rubbing fastness. On the other hand, if the elongation at break is too high, there is a tendency for reduced rubbing fastness; therefore, the elongation at break of the resin particles is preferably 1000% or less, more preferably 990% or less.
[0048] <Determination of Elongation at Break of Resin Particles>
[0049] The elongation at break of resin particles refers to the elongation at break of a resin film test piece made from the resin particles. The elongation at break of resin particles is determined by the following method.
[0050] Resin particles were coated onto a silicone resin sheet to achieve a dried film thickness of 400 μm. After drying at 120°C for 15 minutes, the film was peeled off from the silicone resin sheet to obtain a resin film. The obtained resin film was cut into rectangles 2 cm wide and 4 cm long to prepare resin film test pieces. The elongation at break and tensile strength were measured using the prepared resin film test pieces. The measurements were performed using a Tensilon RTC-1225A universal testing machine (manufactured by ORIENTEC Co., Ltd.). Using the aforementioned testing machine, the resin film test pieces were stretched at a testing temperature of 20°C and a testing speed of 150 mm / min, and the length until breakage (breakage length) was measured. The ratio (%) of the breakage length to the original length of the resin film test piece was taken as the elongation at break.
[0051] The volume average particle size of the resin particles is preferably 10 nm or more and 300 nm or less, more preferably 30 nm or more and 300 nm or less, even more preferably 30 nm or more and 250 nm or less, and particularly preferably 40 nm or more and 220 nm or less.
[0052] The volume average particle size of resin particles can be measured using a particle size distribution measuring device based on the dynamic light scattering method. For example, the "Microtrac UPA" (manufactured by Nikkiso Corporation) can be cited as a particle size distribution measuring device.
[0053] Examples of resin particles used in this embodiment include urethane resins, acrylic resins (including styrene-acrylic resins), fluorene resins, polyolefin resins, rosin-modified resins, terpene resins, polyester resins, polyamide resins, epoxy resins, vinyl chloride resins, vinyl chloride-vinyl acetate copolymers, and ethylene vinyl acetate resins. These resin particles are mostly processed in emulsion form, but can also be in powder form. Furthermore, one type of resin particle can be used alone, or two or more types can be used in combination.
[0054] The resin particles are more preferably urethane-based resins. By using urethane-based resins, printed and dyed products with good rubbing fastness can be obtained.
[0055] Examples of urethane resins include, for example, polyether-type urethane resins that contain ether bonds in addition to urethane bonds in their main chain, polyester-type urethane resins that contain ester bonds in their main chain, and polycarbonate-type urethane resins that contain carbonate bonds in their main chain. Urethane resins can be synthesized using conventional methods or commercially available products can be used. Examples of commercially available urethane resins include PERMARIN (registered trademark) UA-368, UA-200 (trade names manufactured by Sanyo Chemical Co., Ltd.), HYDRAN (registered trademark) WLS-201 (trade name manufactured by DIC Co., Ltd.), and TAKELAC (registered trademark) W-6061 (trade name manufactured by Mitsui Chemicals Co., Ltd.).
[0056] Acrylic resins are polymers obtained by polymerizing at least one acrylic monomer, such as (meth)acrylic acid or (meth)acrylate, as a component. Examples include resins derived from acrylic monomers and copolymers of acrylic monomers with other monomers. Examples of acrylic-vinyl resins include copolymers of acrylic monomers and vinyl monomers. Examples of vinyl monomers include styrene.
[0057] As an acrylic monomer, it can also be used for acrylamide, acrylonitrile, etc.
[0058] Styrene-acrylic resins are copolymers obtained from styrene monomers and (meth)acrylic monomers. Examples include styrene-acrylic acid copolymers, styrene-methacrylic acid copolymers, styrene-methacrylic acid-acrylate copolymers, styrene-α-methylstyrene-acrylic acid copolymers, and styrene-α-methylstyrene-acrylic acid-acrylate copolymers. Commercially available styrene-acrylic resins are also available.
[0059] Polyolefin resins are resins that contain olefins such as ethylene, propylene, and butene in their structural backbone. Well-known polyolefin resins can be selected and used appropriately.
[0060] In addition, the aforementioned resin particles can be supplied in the form of an emulsion, or commercially available resin emulsions can be used.
[0061] 1.1.3. Water
[0062] The inkjet ink composition involved in this embodiment contains water.
[0063] Examples of water include pure water such as ion-exchanged water, ultrafiltration water, reverse osmosis water, and distilled water, as well as ultrapure water, which has undergone extensive removal of ionic impurities. Furthermore, if water sterilized by ultraviolet irradiation or the addition of hydrogen peroxide is used, the growth of bacteria and fungi can be prevented during long-term storage of the composition.
[0064] The water content relative to the total amount of the inkjet ink composition is preferably 50% by mass or more, more preferably 60% by mass or more, and even more preferably 70% by mass or more.
[0065] 1.1.4. Other ingredients
[0066] The inkjet ink composition involved in this embodiment may also include organic solvents, surfactants, pH adjusters, viscosity adjusters, antioxidants, oxygen absorbers, solvents, waxes, chelating agents, mildew inhibitors, preservatives, rust inhibitors, etc.
[0067] <Organic Solvents>
[0068] Printing inkjet ink compositions may also contain organic solvents. Preferably, the organic solvent is water-soluble. Functions of organic solvents include improving the wettability of white ink compositions on fabrics, or improving the moisture retention of printing inkjet ink compositions. Additionally, organic solvents can also function as penetrants.
[0069] As organic solvents, examples include esters, alkylene glycol ethers, cyclic esters, nitrogen-containing solvents, and polyols.
[0070] As esters, examples include glycol monomethyl ether acetate, glycol monoethyl ether acetate, glycol monobutyl ether acetate, and other glycol monoacetates, as well as glycol diacetates, diethylene glycol diacetate, propylene glycol diacetate, and other glycol diesters.
[0071] As alkylene glycol ethers, any mono- or di-ether of an alkylene glycol is acceptable, with alkyl ethers being preferred. Specific examples include ethylene glycol monomethyl ether, ethylene glycol monoethyl ether, ethylene glycol monoisopropyl ether, ethylene glycol monobutyl ether, diethylene glycol monomethyl ether, and alkylene glycol dialkyl ethers, as well as ethylene glycol dimethyl ether, ethylene glycol diethyl ether, ethylene glycol dibutyl ether, diethylene glycol dimethyl ether, diethylene glycol diethyl ether, and other alkylene glycol dialkyl ethers.
[0072] Examples of cyclic esters include β-propiolactone, γ-butyrolactone, δ-valerolactone, ε-caprolactone, β-butyrolactone, and their compounds in which the hydrogen atom of the methylene group adjacent to the carbonyl group is replaced by an alkyl group having 1 to 4 carbon atoms.
[0073] As nitrogen-containing solvents, cyclic amides and non-cyclic amides can be listed. Among non-cyclic amides, alkoxyalkyl amides can be listed.
[0074] As cyclic amides, examples include lactams, such as 2-pyrrolidone, 1-methyl-2-pyrrolidone, 1-ethyl-2-pyrrolidone, 1-propyl-2-pyrrolidone, 1-butyl-2-pyrrolidone, and other pyrrolidones.
[0075] Examples of alkoxyalkylamides include 3-methoxy-N,N-dimethylpropionamide and 3-methoxy-N,N-diethylpropionamide.
[0076] As a nitrogen-containing solvent, its functions include, for example, improving the surface drying and fixing properties of colored ink compositions adhered to fabrics.
[0077] Examples of polyols include 1,2-alkanediols (e.g., ethylene glycol, propylene glycol (also known as propane-1,2-diol), 1,2-butanediol, 1,2-pentanediol, 1,2-hexanediol, 1,2-heptanediol, 1,2-octanediol, etc.) and other polyols (polyols) other than 1,2-alkanediols (e.g., diethylene glycol, dipropylene glycol, glycerol, etc.).
[0078] Examples of polyols include alkanediols and polyols. Among alkanediols, diols of alkanes with 5 or more carbon atoms are preferred. The number of carbon atoms in the alkanes is preferably 5 to 15, more preferably 6 to 10, and even more preferably 6 to 8. 1,2-Alkandiols are preferred.
[0079] The polyols are preferably polyols of alkanes having 4 or fewer carbon atoms, or intermolecular condensations of the hydroxyl groups of polyols of alkanes having 4 or fewer carbon atoms. The alkanes preferably have 2 to 3 carbon atoms. The polyol molecule has 2 or more hydroxyl groups, preferably 5 or less, more preferably 3 or less. When the polyol is an intermolecular condensation as described above, the number of intermolecular condensations is 2 or more, preferably 4 or less, more preferably 3 or less. A single polyol can be used alone, or two or more can be used in combination.
[0080] Alkanediols and polyols primarily function as penetrating and / or moisturizing solvents. Alkanediols tend to be strong penetrating solvents, while polyols tend to be strong moisturizing solvents.
[0081] When the inkjet ink composition contains organic solvents, one type of organic solvent may be used alone, or two or more types may be used in combination. Furthermore, the total content of organic solvents relative to the total amount of the inkjet ink composition is, for example, 5% by mass or more and 50% by mass or less, preferably 10% by mass or more and 45% by mass or less, more preferably 15% by mass or more and 40% by mass or less, and even more preferably 20% by mass or more and 40% by mass or less. By keeping the content of organic solvents within the above range, a better balance between wetting spread and drying properties is achieved, making it easier to form high-quality images.
[0082] <surfactants>
[0083] Printing inkjet ink compositions may also contain surfactants. Surfactants can adjust the surface tension of the ink composition. Specifically, for example, they can adjust the wetting properties with fabrics. Examples of surfactants that can be used include acetylenic glycol surfactants, silicone surfactants, and fluorinated surfactants.
[0084] When the ink composition contains surfactants, it may contain a variety of surfactants. The surfactant content in the ink composition, relative to the total amount of the ink composition, is preferably 0.1% by mass or more and 2% by mass or less, more preferably 0.3% by mass or more and 1.5% by mass or less, and even more preferably 0.5% by mass or more and 1.0% by mass or less.
[0085] <pH adjuster>
[0086] To adjust the pH value, inkjet ink compositions for printing and dyeing can contain pH adjusters. There are no particular limitations on pH adjusters; suitable combinations of acids, bases, weak acids, and weak bases can be listed. Examples of acids and bases used in such combinations include inorganic acids such as sulfuric acid, hydrochloric acid, and nitric acid; inorganic bases such as lithium hydroxide, sodium hydroxide, potassium hydroxide, potassium dihydrogen phosphate, disodium hydrogen phosphate, potassium carbonate, sodium carbonate, sodium bicarbonate, and ammonia; organic bases such as triethanolamine, diethanolamine, monoethanolamine, tripropanolamine, triisopropanolamine, diisopropanolamine, and tris(hydroxymethyl)aminomethane (THAM); and organic acids such as adipic acid, citric acid, succinic acid, and lactic acid.
[0087] Furthermore, as part or all of the pH adjuster, it preferably includes tertiary amines such as triethanolamine and triisopropanolamine, as well as carboxyl-containing organic acids such as adipic acid, citric acid, succinic acid, and lactic acid. By using the above-mentioned acids or bases, a more stable pH buffering effect can be obtained.
[0088] 1.1.5 Physical properties
[0089] The viscosity of the inkjet ink composition for printing and dyeing is preferably 1.5 mPa at 20°C. s or more and 15mPa Below s, more preferably 1.5 mPa s or more and 7mPa Below s, more preferably 1.5 mPa s or more and 5.5 mPa Below s. If the viscosity of the ink composition is within the above range, an image can be effectively formed when the ink composition is applied to the fabric by inkjet printing.
[0090] The surface tension of the ink composition at 25°C is 40 mN / m or less, preferably 38 mN / m or less, more preferably 35 mN / m or less, and even more preferably 30 mN / m or less. If the surface tension of the ink composition is within the above range, the wetting and spreading properties on the fabric become preferable. Furthermore, the surface tension of the ink composition is preferably 20 mN / m or more, more preferably 25 mN / m or more.
[0091] It should be noted that the surface tension can be measured by using an automatic surface tension meter CBVP-Z (manufactured by Kyowa Interface Science Co., Ltd.) to confirm the surface tension when the platinum plate is wetted with the composition at 25°C.
[0092] 1.1.6. Manufacturing Method
[0093] The inkjet ink composition for printing and dyeing can be obtained by mixing white pigment, resin particles, water, and other components added as needed in any order, and removing impurities by filtration as needed. As a method for mixing the components, it is preferable to use a method in which the materials are added sequentially and stirred in a container equipped with a stirring device such as a mechanical stirrer or magnetic stirrer. As a filtration method, centrifugal filtration, filter filtration, etc., can be performed as needed.
[0094] 1.2. Treatment liquid composition
[0095] The treatment liquid composition involved in this embodiment contains particles containing organic polysiloxane and water.
[0096] The components contained in the treatment liquid composition according to this embodiment will be described in detail below.
[0097] 1.2.1. Particles containing organopolysiloxanes
[0098] The treatment liquid composition according to this embodiment contains particles containing organopolysiloxane. These particles are not particularly limited as long as they contain organopolysiloxane; for example, they can be the organopolysiloxane particles themselves, or particles in which the organopolysiloxane is dispersed by an emulsifier or the like. The organopolysiloxane in these particles can be solid or liquid. For example, when an oily organopolysiloxane is dispersed in water in particulate form by an emulsifier, the dispersed particles are equivalent to particles containing organopolysiloxane.
[0099] Organopolysiloxanes are based on siloxane bonds "-Si(R) 1 R 2 The backbone is "-O-", and methyl, phenyl, vinyl, amino, etc. are attached thereto as organic groups R. 1 R 2 The term "silicone" refers to a general category of silicone compounds. Organopolysiloxanes, based on their chemical composition and molecular weight, exist in oil, rubber, and resin forms, and are sometimes referred to as silicone oil, silicone rubber, or silicone resin, respectively. It should be noted that the organopolysiloxanes used in the treatment liquid composition involved in this embodiment are preferably high molecular weight compounds.
[0100] The organopolysiloxane used in the treatment liquid composition according to this embodiment is more preferably an oily compound. If the organopolysiloxane is an oily compound, it can be easily and stably dispersed into particles in an aqueous matrix by the emulsification treatment described later.
[0101] The molecular structure of organopolysiloxanes is not particularly limited, and examples include linear, branched, cyclic, mesh-like, and cage-like structures. When the molecular structure of an organopolysiloxane is non-cyclic, one or more groups selected from hydrocarbon groups, alkoxy groups, hydroxyl groups, hydrogen atoms, and halogens are usually bonded to the Si atom at the end of the molecule.
[0102] In addition, organopolysiloxanes can also be used as commercially available silicone oils. Examples include dimethyl silicone oil, methylphenyl silicone oil, methylhydrosilicone oil, polyether-modified silicone oil, aralkyl-modified silicone oil, fluoroalkyl-modified silicone oil, long-chain alkyl-modified silicone oil, higher aliphatic ester-modified silicone oil, higher fatty acid amide-modified silicone oil, polyether-long-chain alkyl-aralkyl-modified silicone oil, long-chain alkyl-aralkyl-modified silicone oil, phenyl-modified silicone oil, and polyether-methoxy-modified silicone oil.
[0103] In the examples of organopolysiloxanes described above, nonionic silicones are preferred. Because nonionic silicones are chemically stable, the resulting images exhibit less yellowing compared to ionic silicones. Furthermore, when using ionic silicones, the smoke generated during recording adheres to adjacent nozzles, easily causing nozzle clogging. By using nonionic silicones, nozzle clogging caused by smoke can be reduced, improving the stability of continuous printing.
[0104] Furthermore, dimethyl silicone is a more preferred organopolysiloxane. By using non-ionic dimethyl silicone, the spraying during printing and dyeing is more stable, which can improve the stability of continuous printing.
[0105] Commercially available dimethyl silicone oils include oil-based dispersants such as the KF-96 series (trade name manufactured by Shin-Etsu Chemical Industry Co., Ltd., dimethyl silicone).
[0106] The viscosity of silicone, for example, at 25°C is preferably 1000 mPa. Below s, and preferably 50 mPa. s or more, preferably 500 mPa s or above and 900mPa Below s, more preferably 600 mPa s or more and 700 mPa Below s. Furthermore, there is no particular limitation on the viscosity of the base oil when silicone is emulsified and dispersed, but an upper limit of 1,000,000 mm is preferably specified. 2 / s or less, more preferably 100000 mm 2 For speeds below / s, the lower limit is preferably 10mm. 2 / s or higher, more preferably 100mm 2 / s or higher. It should be noted that base oil viscosity indicates the viscosity of the base oil, and is a value obtained by measuring the internal resistance of the base oil. Therefore, the higher the base oil viscosity value, the higher the viscosity, and the lower the value, the lower the viscosity.
[0107] Organopolysiloxanes can also be emulsified using various surfactants as emulsifiers to form particulate particles (emulsified particles) for blending. That is, particles containing organopolysiloxanes can also be emulsified particles containing silicone oil. As emulsifiers in this case, for example, nonionic surfactants, anionic surfactants, cationic surfactants, amphoteric surfactants, phospholipids, etc., can be used.
[0108] The amount of emulsifier added when emulsifying organopolysiloxane is preferably less than 20% by mass of the total amount of the emulsified composition, more preferably 15% by mass or less, and particularly preferably 10% by mass or less.
[0109] In addition, the average particle size of the emulsified particulate organopolysiloxane is 2 μm or less, preferably 1 μm or less, and more preferably in the range of 0.2 to 0.8 μm.
[0110] The content of organopolysiloxane particles in the processing liquid composition according to this embodiment is preferably 15.0% by mass or less, more preferably 13.0% by mass or less, and even more preferably 10.0% by mass or less, relative to the total amount of the processing liquid composition. If the content of organopolysiloxane particles is within the above range, the spraying of the processing liquid composition during printing and dyeing can be more stable, improving the stability of continuous printing. Furthermore, the content of organopolysiloxane particles is preferably 5.0% by mass or more, more preferably 6.0% by mass or more, and even more preferably 7.0% by mass or more. If the content of organopolysiloxane particles is within the above range or more, the hand feel of the printed and dyed material becomes better.
[0111] Furthermore, it is preferable that the content of organopolysiloxane particles relative to the total mass of the treatment liquid composition is greater than the content of resin particles relative to the total mass of the printing and dyeing inkjet ink composition. By making the content of organopolysiloxane particles greater than the content of resin particles, the rubbing fastness of the printed and dyed material can be further improved.
[0112] The content of organopolysiloxane particles relative to the total solids content in the treatment liquid composition is preferably 90.0% by mass or more. That is, of the solids remaining after the treatment liquid composition is dried, preferably 90.0% by mass or more is organopolysiloxane. The content of organopolysiloxane particles relative to the total solids content in the treatment liquid composition is more preferably 95.0% by mass or more, further preferably 98% by mass or more, and particularly preferably 99.0% by mass or more.
[0113] If the content of particles containing organopolysiloxanes is 90.0% by mass or more relative to the total solids content in the treatment liquid composition, a more fully formed low-refractive-index coating film is more easily formed, resulting in better color development of the printed and dyed materials. Furthermore, when the treatment liquid composition is ejected using an inkjet printer, the ejection is stable, improving the stability of continuous printing.
[0114] 1.2.2. Water
[0115] The treatment liquid composition involved in this embodiment contains water.
[0116] Examples of water include pure water such as ion-exchanged water, ultrafiltration water, reverse osmosis water, and distilled water, as well as ultrapure water, which has undergone extensive removal of ionic impurities. Furthermore, if water sterilized by ultraviolet irradiation or the addition of hydrogen peroxide is used, the growth of bacteria and fungi can be prevented during long-term storage of the composition.
[0117] The water content relative to the total amount of the treatment liquid composition is preferably 30% by mass or more, more preferably 40% by mass or more, and even more preferably 50% by mass or more. It should be noted that the water in the treatment liquid composition refers to, for example, water contained in the organopolysiloxane dispersion used as a raw material and added water. If the water content is within the above range, the treatment liquid composition can have a low viscosity. Furthermore, the total amount of the treatment liquid composition relative to the water content is preferably 90% by mass or less, more preferably 85% by mass or less, and even more preferably 80% by mass or less.
[0118] 1.2.3. Other ingredients
[0119] The processing liquid composition described in this embodiment may also contain coloring materials. Furthermore, the processing liquid composition may also contain components found in inkjet printing ink compositions, provided that its function and dispersion structure are not impaired.
[0120] <Coloring Materials>
[0121] The content of coloring material in the processing liquid composition is preferably 0.1% by mass or less, more preferably 0.01% by mass or less, and even more preferably does not contain any coloring material. When the processing liquid composition contains only a small amount of coloring material, or no coloring material at all, the low refractive index property of the coating film formed by the organopolysiloxane can be more effectively brought out. That is, when the processing liquid composition contains only a small amount of coloring material, or no coloring material at all, light incident on the coating film is less likely to be blocked by the coloring material, which can further improve the color development of white produced by the inkjet ink composition.
[0122] 1.2.4.Physical properties
[0123] The viscosity of the treatment fluid composition is preferably 1.5 mPa at 20°C. s or more and 15mPa Below s, more preferably 1.5 mPa s or more and 7mPa Below s, more preferably 1.5 mPa s or more and 5.5 mPa Below s. If the viscosity of the processing liquid composition is within the above range, an image can be effectively formed when it is attached to the fabric by inkjet printing.
[0124] The surface tension of the treatment liquid composition at 25°C is 40 mN / m or less, preferably 38 mN / m or less, and more preferably 35 mN / m or less. If the surface tension of the treatment liquid composition at 25°C is within the above range, the wetting and spreading properties on the fabric become preferable. Furthermore, the surface tension of the treatment liquid composition at 25°C is preferably 20 mN / m or more, more preferably 25 mN / m or more, and even more preferably 30 mN / m or more.
[0125] 1.2.5. Manufacturing method and usage method
[0126] The treatment liquid composition can be obtained by mixing particles containing organopolysiloxane, water, and other components as needed in any order, and removing impurities by filtration as required. As a method for mixing the components, it is preferable to add the materials sequentially and mix them by stirring in a container equipped with a stirring device such as a mechanical stirrer or magnetic stirrer. As a filtration method, centrifugal filtration, filter filtration, etc., can be performed as needed.
[0127] The treatment liquid composition is applied to a fabric. Methods for adhering the treatment liquid composition to the fabric include inkjet printing using an inkjet recording device, application using rollers, rods, or brushes, and application using various sprayers.
[0128] The application of the treatment liquid composition is preferably performed by inkjet printing. By using inkjet printing to spray the treatment liquid composition, it is possible to apply it to a specified area with a specified amount of coating, thus enabling the treatment liquid composition to adhere effectively.
[0129] 1.3 Non-white inkjet ink compositions
[0130] The composition group according to this embodiment can further include a non-white inkjet ink composition. By further including a non-white inkjet ink composition in the composition group, it is also possible to print color images based on a white ink composition. In addition, by bonding the resin contained in the white ink composition with the resin contained in the non-white ink composition, the printed material develops color better, and the rubbing fastness of the printed image is also improved.
[0131] Non-white inkjet ink compositions contain non-white pigments, resin particles, and water.
[0132] Non-white inkjet ink compositions contain non-white pigments, which are so-called colored inks, such as blue-green, yellow, magenta, black, or special color pigments like pearl.

[0143] Pigments are preferably able to be stably dispersed in a dispersion medium; therefore, pigment dispersants can also be used to disperse them.

[0147] The manufacturing method of non-white inkjet ink compositions is as described in section "1.1.6. Manufacturing Method", therefore detailed descriptions are omitted.
[0148] 2. Inkjet printing recording method
[0149] The composition group comprising the above-described inkjet ink composition and processing liquid composition is used in inkjet printing. The inkjet printing recording method is described below.
[0150] An embodiment of the present invention relates to an inkjet printing and recording method (hereinafter also referred to as a "recording method"), which includes: an ink adhesion step of adhering the above-mentioned printing and dyeing inkjet ink composition to a fabric by inkjet printing; and a treatment liquid adhesion step of adhering the above-mentioned treatment liquid composition to the fabric after the ink adhesion step.
[0151] The following will describe the process in the order of the inkjet recording device and the inkjet printing and recording method used in the inkjet process.
[0152] 2.1. Inkjet recording device
[0153] Regarding an example of an inkjet recording apparatus (hereinafter also referred to as a "recording apparatus") capable of implementing the inkjet printing and recording method involved in this embodiment, see reference to... Figure 1 Please provide an explanation.
[0154] The recording apparatus according to this embodiment includes an attachment mechanism for performing the ink attachment process described later and an attachment mechanism for performing the processing liquid attachment process described later. The following description is an example of performing the processing liquid attachment process using an inkjet recording apparatus, but the processing liquid attachment process is not limited to the inkjet method using an inkjet recording apparatus.
[0155] It should be noted that the inkjet recording device used in the following description is a serial printer. This serial printer has an inkjet head mounted on a carriage that moves in a predetermined direction. The inkjet head moves with the carriage, thereby ejecting droplets onto the fabric. The inkjet recording device applicable to the recording method described in this embodiment is not limited to a serial printer; a line printer can also be used. A line printer is a printer in which the inkjet head is formed to be wider than the width of the fabric, and the inkjet head does not move while ejecting droplets onto the fabric.
[0156] An inkjet recording device is a device that prints on fabric by having an inkjet head, which is a liquid ejection unit that ejects tiny droplets of ink composition and reaction liquid, cause the droplets to fall onto the fabric. Figure 1 This is a schematic perspective view showing the inkjet recording apparatus used in this embodiment.
[0157] like Figure 1As shown, in this embodiment, the printer 1 includes an inkjet head 3, a carriage 4, a main scanning mechanism 5, a paper pressure roller 6, and a control unit (not shown) that controls the overall operation of the printer 1. The carriage 4 carries the inkjet head 3 and is detachable from liquid cartridges 7a, 7b, 7c, 7d, 7e, and 7f, which store the ink composition and processing liquid composition supplied to the inkjet head 3.
[0158] The main scanning mechanism 5 includes a timing belt 8 connected to the bracket 4, a motor 9 driving the timing belt 8, and a guide shaft 10. The guide shaft 10 serves as a support component for the bracket 4 and is mounted on the scanning direction of the bracket 4, i.e., the main scanning direction MS. The bracket 4 is driven by the motor 9 via the timing belt 8 and can reciprocate along the guide shaft 10. Thus, the main scanning mechanism 5 has the function of enabling the bracket 4 to reciprocate in the main scanning direction MS.
[0159] The pressure roller 6 has the function of conveying the fabric 2 to be printed in the secondary scanning direction SS, which is orthogonal to the main scanning direction MS, i.e., the length direction of the fabric 2. Thus, the fabric 2 is conveyed in the secondary scanning direction SS. The carrier 4, which carries the inkjet head 3, is configured to reciprocate in the main scanning direction MS, which is approximately the same as the width direction of the fabric 2. The inkjet head 3 can scan relative to the fabric 2 in both the main scanning direction MS and the secondary scanning direction SS.
[0160] Liquid containers 7a, 7b, 7c, 7d, 7e, and 7f are six independent liquid containers. These containers can hold the ink composition and processing liquid composition used in the recording method of this embodiment. Each of these liquid containers contains an ink composition and a processing liquid composition in colors such as black, blue-green, magenta, yellow, white, and orange, and they can be used in any combination. Figure 1 The number of liquid cartridges is 6, but not limited to this. Supply ports (not shown) are provided at the bottom of liquid cartridges 7a, 7b, 7c, 7d, 7e, and 7f. These supply ports are used to supply the ink composition or processing liquid composition contained in each liquid cartridge to the inkjet head 3.
[0161] The inkjet head 3, under the control of a control unit (not shown), sprays ink compositions and processing liquid compositions supplied from liquid cartridges 7a, 7b, 7c, 7d, 7e, and 7f from multiple nozzles onto the fabric 2, causing it to adhere. The inkjet head 3 has multiple nozzles on its surface opposite the fabric 2 to which the ink compositions and processing liquid compositions are adhered. These multiple nozzles are arranged in a row to form a nozzle array, and each nozzle array is respectively configured corresponding to a different colored ink composition and processing liquid composition. Each colored ink composition and processing liquid composition is supplied from its respective liquid cartridge to the inkjet head 3 and ejected as droplets from the nozzles via an actuator (not shown) within the inkjet head 3. The ejected droplets of ink compositions and processing liquid compositions land on the fabric 2, causing adhesion processing and forming ink-based images, text, patterns, colors, etc., on the printed area of the fabric 2. It should be noted that multiple inkjet heads 3 may also be mounted on a carrier 4.
[0162] Here, a piezoelectric element is used as the drive unit, i.e., the actuator, in the inkjet head 3, but it is not limited to this method. For example, an electromechanical conversion element that displaces the vibrating plate as an actuator by electrostatic adsorption, or an electrothermal conversion element that ejects the ink composition as droplets by bubbles generated by heating, can also be used.
[0163] The inkjet head 3 has a nozzle group for ejecting a processing liquid composition and a nozzle group for ejecting an ink composition. The ejected nozzle group refers to the nozzle group used for recording in the recording method. During the main scan, if an image to be recorded exists in the area of the fabric opposite to this nozzle group, it is a group of nozzles that can eject ink or the like from the nozzles, and it is a continuous nozzle group in the sub-scanning direction SS. Therefore, although the nozzle group itself exists, nozzle groups not used for recording in the recording method are not included in the ejected nozzle group.
[0164] Figure 2 , Figure 3 as well as Figure 4 This is an example showing the configuration of the printhead 3. Figure 2 In this configuration, inkjet heads 3a and 3b are arranged from the upstream side to the downstream side in the transport direction (sub-scanning direction SS). Additionally, in... Figure 3 In this configuration, inkjet heads 3a and 3b are located at the same position in the sub-scanning direction SS and are arranged laterally. Additionally, in... Figure 4 In the middle, there are overlapping parts, and inkjet heads 3a and 3b are arranged from the upstream side to the downstream side in the transport direction (sub-scanning direction SS).
[0165] In the recording method according to this embodiment, the inkjet head 3 preferably has a structure in which the nozzle group for recording the processing liquid composition is located downstream of or overlapping the fabric in the direction of fabric transport. Furthermore, from the same viewpoint, it is preferable that the nozzle for ejecting the processing liquid composition is located at the same position relative to the fabric transport direction as the nozzle for ejecting the ink composition, or downstream of the nozzle for ejecting the ink composition relative to the fabric transport direction.
[0166] With this structure, the same scanned area of the fabric can be coated with ink followed by a treatment liquid (alternating coating) using the same main scan; or with different main scans, the treatment liquid can be coated with ink followed by a treatment liquid (treatment liquid coating). Preferably, the inkjet ink composition and the treatment liquid are coated with ink followed by a treatment liquid using different main scans (treatment liquid coating).
[0167] For example, in Figure 2 In this example, by making inkjet head 3a a printhead for ejecting the ink composition and inkjet head 3b a printhead for ejecting the processing liquid composition, the nozzle group for the processing liquid composition used in recording can be positioned downstream of the nozzle group for the ink composition used in recording relative to the fabric transport direction (sub-scanning direction SS). In this case, the processing liquid composition adheres to the fabric after the ink composition. That is, post-ejection of the processing liquid composition is possible, and a layer containing the ink composition can be formed, followed by the lamination of the layer containing the processing liquid composition.
[0168] For example, in Figure 3 In the example, inkjet head 3a is used as the printhead for ejecting the ink composition, and inkjet head 3b is used as the printhead for ejecting the processing liquid composition. Furthermore, when the nozzle group for recording the processing liquid composition and the nozzle group for recording the ink composition have overlapping portions, alternating ejection is possible. That is, a layering (layered cake-like layering) of alternating overlap of the processing liquid composition and the ink composition is possible.
[0169] It should be noted that the "overlapping portion" refers to the portion of the nozzle assembly for the ink composition used in recording and the nozzle assembly for the processing liquid composition used in recording that is located at the same position in the sub-scanning direction SS. Thus, the ink composition and the processing liquid composition overlap and adhere to the fabric under the same main scan.
[0170] For example, in Figure 4In the example, inkjet head 3a is used as the printhead for ejecting the ink composition, and inkjet head 3b is used as the printhead for ejecting the processing liquid composition. Furthermore, when the nozzle group for recording the processing liquid composition and the nozzle group for recording the ink composition have overlapping portions, alternating ejection is possible. Additionally, when inkjet head 3a is used as the printhead for ejecting the ink composition, and inkjet head 3b is used as the printhead for ejecting the processing liquid composition, and there is no overlapping portion between the nozzle group for recording the processing liquid composition and the nozzle group for recording the ink composition, but the nozzle group for recording the processing liquid composition is located downstream of the fabric transport direction (sub-scanning direction SS) closer to the nozzle group for recording the ink composition, ejection after the processing liquid composition is possible.
[0171] 2.2 Ink Adhesion Process
[0172] The ink adhesion process is a process of applying a printing inkjet ink composition to fabric using an inkjet method.
[0173] The ink application process can be performed in any manner if an inkjet method is used, in which the ink composition is applied while the inkjet head scans the fabric. The inkjet method can also be a main scanning method that records data by moving the inkjet head in a direction perpendicular to the fabric's transport direction.
[0174] The preferred adhesion amount of the ink composition in the ink adhesion process is 5.0 mg / inch. 2 ) or higher. More preferably, 7.0 (mg / inch). 2 ) or higher, more preferably 9.0 (mg / inch) 2 ) or above, especially preferably 10.0 (mg / inch) 2 ) or above, and more particularly preferably 13.0 (mg / inch) 2 ) or above, especially preferably 15.0 (mg / inch) 2 The above applies. If the amount of ink composition adhered to is within the above range, a colored image exhibiting better color rendering can be obtained.
[0175] In addition, the adhesion amount of the ink composition is preferably 50.0 (mg / inch). 2 40.0 (mg / inch) or less, more preferably 40.0 (mg / inch) 2 Below 25.0 mg / inch, more preferably 25.0 mg / inch. 2 )the following.
[0176] 2.3. Processing liquid adhesion procedure
[0177] The inkjet printing and recording method according to this embodiment includes a treatment liquid adhesion step after the ink adhesion step, in which the above-mentioned treatment liquid composition is adhered to the fabric on which the ink composition is adhered.
[0178] The following describes the process of applying the treatment liquid.
[0179] Methods for applying the treatment liquid composition used in the treatment liquid application process include inkjet printing using an inkjet recording device, coating using rollers, rods, and brushes, and coating using various sprayers. Among these, inkjet printing is preferred in the treatment liquid application process. Inkjet printing can be performed in any way, as long as the inkjet head scans the fabric while applying the treatment liquid composition.
[0180] Inkjet printing can also be a method of recording by moving the inkjet head in a direction perpendicular to the fabric transport direction. Details will be described later. The ink composition and processing liquid composition can be compositions in which the ink composition is applied to the same scanned area of the fabric via the same main scan, followed by the application of the processing liquid composition (alternating application). Alternatively, the ink composition and processing liquid composition can be compositions in which the ink composition is applied via different main scans, followed by the application of the processing liquid (processing liquid post-application). Preferably, the ink composition and processing liquid composition are those in which the ink composition is applied via different main scans, followed by the application of the processing liquid composition (processing liquid post-application).
[0181] The processing liquid adhesion step can be performed after the ink adhesion step. For example, the processing liquid composition can be adhered to the ink composition by a main scan that is the same as the main scan for adhering the ink composition, or the processing liquid composition can be adhered to the ink composition by a subsequent main scan that is different from the main scan for adhering the ink composition. It should be noted that, in the case where the inkjet printing and dyeing recording method according to this embodiment includes the non-white ink composition adhesion step described later, the processing liquid adhesion step is performed after the non-white ink composition adhesion step.
[0182] From the viewpoint of promoting the drying of the ink composition and minimizing the mixing of the processing liquid composition and the ink composition, it is preferable to have the processing liquid composition adhere to the ink composition in a subsequent main scan, which is different from the main scan with the ink composition attached. Furthermore, since the processing liquid composition and the ink composition are difficult to mix, the color development of the image is less likely to be compromised.
[0183] The preferred adhesion amount of the treatment liquid composition is 5 (g / m³). 2 ) or more and 100 (g / m 2 ) or less, more preferably 10 (g / m 2 ) or above and 70 (g / m 2) or less, more preferably 10 (g / m 2 ) or above and 55 (g / m 2 The following applies. If the amount of the treatment liquid composition adhering to it is within the above range, a better color development image can be obtained.
[0184] 2.4. Drying process
[0185] The inkjet printing and recording method described in this embodiment may also include a drying process.
[0186] As a drying process, it can be performed by using a drying mechanism to dry the recording medium. Examples of drying mechanisms include those that supply air at room temperature or hot air to the recording medium (air-supply type), those that irradiate the recording medium with radiation (infrared rays, etc.) to generate heat (radiation type), those that transfer heat to the recording medium through contact with the recording medium (conduction type), and combinations of two or more of these mechanisms. In cases where a drying process is included, it is preferable to perform the drying by heating the recording medium. The case where a drying mechanism that heats the recording medium is used is specifically referred to as a heating process.
[0187] The drying process is preferably performed after the treatment liquid adhesion process. If the drying process is performed after the treatment liquid adhesion process, the printed and dyed materials exhibit good rubbing fastness.
[0188] The temperature of the fabric at the point of adhesion of the inkjet ink composition and the processing liquid composition is preferably 20°C or higher and 45°C or lower, more preferably 27°C or higher and 40°C or lower, and even more preferably 28°C or higher and 30°C or lower. This temperature is the surface temperature of the portion of the recording surface of the recording medium that receives the liquid during the adhesion process, and is the highest temperature of the adhesion process in the recording area. If the surface temperature of the fabric is within the above range, the printed image can be clearer, exhibiting good rubbing adhesion.
[0189] There are no particular limitations on the method for heating fabric; examples include hot pressing, atmospheric pressure steam heating, high pressure steam heating, and thermosetting. There are also no particular limitations on the heat source; for example, infrared lamps can be used. The preferred heating temperature is the temperature at which the resin particles in the ink composition are melted and the medium, such as moisture, evaporates.
[0190] The heating temperature is preferably 160°C or higher, more preferably 170°C or higher, and even more preferably 180°C or higher. If the heating temperature is within the above range, the resin particles in the ink composition are further fixed, and the rubbing fastness of the printed material becomes better. Furthermore, the heating temperature is preferably 250°C or lower, more preferably 200°C or lower.
[0191] There is no specific limit to the heating time, for example, more than 30 seconds and less than 20 minutes.
[0192] It should be noted that, if the non-white ink composition adhesion step (described later) is further included after the liquid treatment step, the drying step is preferably performed after the non-white ink composition adhesion step. By performing the drying step after the non-white ink composition adhesion step, the rubbing adhesion of the image formed on the fabric becomes better.
[0193] 2.5. Other processes
[0194] The inkjet printing recording method may also include the following steps as needed.
[0195] 2.5.1. Pretreatment solution adhesion process
[0196] Inkjet printing recording methods may also include a pretreatment solution application process. The pretreatment solution application process is the process of applying the pretreatment solution to the fabric. The pretreatment solution application process will be explained below.
[0197] The pretreatment solution used in the pretreatment process may also contain a coagulant that causes the components of the inkjet ink composition to agglomerate. The coagulant has the function of agglomerating pigments and resin particles by reacting with components such as pigments and resin particles contained in the ink composition. Through such agglomeration, for example, the color development of the pigment can be improved, the fixing properties of the resin particles can be improved, and / or the viscosity of the ink composition can be increased.
[0198] There are no particular limitations on the coagulant; examples include metal salts, inorganic acids, organic acids, and cationic compounds. As a cationic compound, cationic resins (cationic polymers) and cationic surfactants can be used. Among these, polyvalent metal salts are preferred as metal salts, and cationic resins are preferred as cationic compounds. Therefore, from the viewpoint of obtaining particularly superior image quality, abrasion resistance, and gloss, cationic resins, organic acids, and polyvalent metal salts are preferred as coagulants.
[0199] The content of coagulant in the pretreatment solution is not limited. For example, it is preferably 0.1% by mass or more and 20% by mass or less relative to the total mass of the pretreatment solution, more preferably 1% by mass or more and 20% by mass or less, and even more preferably 2% by mass or more and 15% by mass or less.
[0200] Pretreatment solutions may contain components found in inkjet ink compositions, provided they do not impair their function.
[0201] As a method for adhering the pretreatment liquid to the fabric, any one or a combination of non-contact and contact methods can be used, such as inkjet printing using an inkjet recording device, coating using rollers, rods and brushes, coating using various sprayers, etc.
[0202] The pretreatment solution application process can also be performed using inkjet printing. In this case, the viscosity at 20°C is preferably 1.5 mPa. s or more and 15mPa Below s, more preferably 1.5 mPa s or more and 7mPa Below s, more preferably 1.5 mPa s or more and 5.5 mPa Below s. When the pretreatment solution is applied to the recording medium by inkjet printing, it can be applied to a specified area with a specified amount, and the pretreatment solution can be effectively adhered.
[0203] The application of the pretreatment liquid in the pretreatment liquid application step is preferably performed before or simultaneously with the application of the inkjet ink composition to the recording medium in the ink application step. That is, for a recording medium to which the pretreatment liquid has been applied in the pretreatment liquid application step, it is preferable to perform the application of the ink composition in the ink application step, or to perform the application of the pretreatment liquid in the pretreatment liquid application step and the application of the ink composition in the ink composition application step simultaneously.
[0204] 2.5.2. Non-white ink composition adhesion process
[0205] The inkjet printing and recording method described in this embodiment may also include a non-white ink composition adhesion step. The non-white ink composition adhesion step is a process of adhering a non-white ink composition to fabric using an inkjet method. Through this step, color images based on a white ink composition can be printed. It should be noted that the non-white ink composition adhesion step is defined as "2.2. Ink Adhesion Step".
