Description

[Technical Field]

[0001] The present invention relates to a textile printed image, an inkjet ink, an overcoat layer forming liquid, a pretreatment liquid, and an image forming apparatus. [Background technology]

[0002] As a conventional textile printing method, exhaustion printing, in which a fabric is immersed in a bath filled with a dye, has been known, but this method requires a long time for dyeing, resulting in low production efficiency.In recent years, so-called inkjet printing, in which an image is formed on a fabric by an inkjet method, has become widely used because it allows dyeing in a short time and has high production efficiency.

[0003] In inkjet printing, minute droplets of ink are ejected from an inkjet recording head and landed on a fabric to form an image. For example, Patent Document 1 discloses a method for producing a textile print by such inkjet printing. [Prior art documents] [Patent documents]

[Brief explanation of the drawings]

[0010] [Figure 1] FIG. 1 is a schematic diagram showing an image forming apparatus according to this embodiment. [Figure 2] FIG. 2 is a schematic diagram showing an outline of the bending test. DETAILED DESCRIPTION OF THE INVENTION

[0011] In order to suppress stickiness of a printed image having a pretreatment layer, a fixing layer, and an overcoat layer, it is conceivable to harden the resin contained in the fixing layer formed on the pretreatment layer, for example. However, hardening the resin contained in the fixing layer will deteriorate the texture of the fabric on which the printed image is formed. Thus, in a printed image, there is a trade-off between suppressing stickiness of the printed image and the texture of the fabric, and it is difficult to achieve both.

[0012] However, with the printed image according to the embodiment of the present invention, it is possible to achieve both suppression of stickiness and texture.

[0013] The suppression of stickiness can be evaluated by a small coefficient of friction of the printed image, and the feel can be evaluated by a small bending torque of the fabric on which the printed image is formed (printed image-formed product).

[0014] Specifically, the printed image formed according to the present embodiment has a deposition amount of the printed image (total deposition amount of the pretreatment layer, the fixing layer, and the overcoat layer) of 1 g / m 2 ~10g / m 2 When a fabric on which a printed image is formed (a printed image-formed product) and a fabric on which no printed image is formed are measured using a friction tester KES-SE, the difference in the mean coefficient of friction MIU should be 0.42 or less. It is also preferable that the difference in the mean deviation of the mean coefficient of friction MMD be 0.24 or less. In addition, the printed image formed product according to the present embodiment has a print image adhesion amount of 1 g / m 2 ~10g / m 2 When a fabric on which a printed image is formed (a printed image-formed product) and a fabric on which a printed image is not formed are measured using a bending tester KES-FB2-A, the difference in bending torque is 0.006 gf cm or less. The amount of adhesion of the printed image is 1 g / m 2 ~10g / m 2 3g / m 2 ~10g / m 2 More preferably, it is 3 g / m 2 ~8g / m 2 It is more preferable that:

[0015] The fabric on which the printed image is formed is not particularly limited as long as it can form a printed image. Examples of the types of fiber material constituting this fabric include natural fibers such as cotton (cellulose fiber), hemp, wool, and silk; and chemical fibers such as rayon, vinylon, nylon, acrylic, polyurethane, polyester, and acetate. The fabric may be made from these fibers in any form, such as woven fabric, nonwoven fabric, or knitted fabric. The fabric may also be a blended woven fabric or blended nonwoven fabric of two or more types of fibers. The fabric is preferably, for example, cotton satin.

[0016] As described above, the printed image of the printed image-formed product according to the present embodiment has a pretreatment layer, a fixing layer, and an overcoat layer, which are formed by a pretreatment liquid, an inkjet ink, and an overcoat layer-forming liquid, respectively. Each of these will be described below.

[0017] 1-1. Pretreatment solution The pretreatment liquid is first applied to the fabric. The application of the pretreatment liquid to the fabric forms a pretreatment layer. The pretreatment liquid contains a cationic resin, which promotes aggregation of the fixing resin and the pigment in the inkjet ink, thereby promoting fixing of the fixing layer.

[0018] The weight-average molecular weight (Mw) of the cationic resin is preferably 1,000 or more from the viewpoint of suppressing stickiness of the printed image. On the other hand, the upper limit of the weight-average molecular weight of the cationic resin is preferably 10,000 or less from the viewpoint of dispersibility in the pretreatment liquid. In other words, the weight-average molecular weight of the cationic resin is preferably 1,000 to 10,000. The weight-average molecular weight (Mw) of the cationic resin can be measured by gel permeation chromatography in polystyrene equivalent terms.

[0019] Examples of cationic resins include polyamines, diallylamine hydrochloride polymers, diallylamine polymers, methyldiallylamine hydrochloride polymers, methyldiallylamine amidosulfate polymers, methyldiallylamine acetate polymers, diallyldimethylammonium chloride polymers, diallylmethylethylammonium ethylsulfate polymers, amine-epichlorohydrin condensation polymers, poly-2-hydroxypropyldimethylammonium chloride, dimethylamine-ethylenediamine-epichlorohydrin condensates, dimethylamine-ammonia-epichlorohydrin condensates, and the like.

[0020] Examples of commercially available cationic resins include PAS-HL manufactured by Nittobo Medical Co., Ltd., Catiomaster (registered trademark) PD-7, PD-30, and PE-30 manufactured by Yokkaichi Synthetic Co., Ltd., and Unisense KHE manufactured by Senka Corporation.

[0021] The content of the cationic resin in the pretreatment liquid is preferably 0.1% by mass to 10% by mass.

[0022] The method for applying the pretreatment liquid is not particularly limited and may be, for example, a pad method, a coating method, a spray method, an inkjet method, etc. The pretreatment liquid applied to the fabric may be heated and dried using hot air, a hot plate, or a heat roller.

[0023] 1-2. Inkjet ink The inkjet ink is applied onto the pretreatment layer. The application of the inkjet ink onto the pretreatment layer forms a fixing layer. The inkjet ink contains a fixing resin, and aggregation of the fixing resin is promoted by the cationic resin contained in the pretreatment layer. This promotes fixing of the fixing layer.

[0024] In this embodiment, the inkjet ink contains a pigment, a fixing resin, a surfactant, and an aqueous medium. Each component will be described below, along with the properties and preparation of the inkjet ink.

[0025] (pigment) The pigment is not particularly limited, but may be, for example, an organic pigment or an inorganic pigment having the following numbers listed in the Color Index.

[0026] Examples of orange or yellow pigments include CI Pigment Orange 31, CI Pigment Orange 43, CI Pigment Yellow 12, CI Pigment Yellow 13, CI Pigment Yellow 14, CI Pigment Yellow 15, CI Pigment Yellow 17, CI Pigment Yellow 74, CI Pigment Yellow 83, CI Pigment Yellow 93, CI Pigment Yellow 94, CI Pigment Yellow 128, CI Pigment Yellow 138, CI Pigment Yellow 151, CI Pigment Yellow 154, CI Pigment Yellow 155, CI Pigment Yellow 180, CI Pigment Yellow 185, and CI Pigment Yellow 213.

[0027] Examples of red or magenta pigments include Pigment Red 3, 5, 19, 22, 31, 38, 43, 48:1, 48:2, 48:3, 48:4, 48:5, 49:1, 53:1, 57:1, 57:2, 58:4, 63:1, 81, 81:1, 81:2, 81:3, 81:4, 88, 104, 108, 112, 122, 123, 144, 146, 149, 166, 168, 169, 170, 177, 178, 179, 184, 185, 208, 216, 226, 257, Pigment Violet 3, 19, 23, 29, 30, 37, 50, 88, and Pigment Orange 13, 16, 20, and 36.

[0028] Examples of blue or cyan pigments include Pigment Blue 1, 15, 15:1, 15:2, 15:3, 15:4, 15:6, 16, 17-1, 22, 27, 28, 29, 36, 60.

[0029] Examples of green pigments include Pigment Green 7, 26, 36, and 50. Examples of yellow pigments include Pigment Yellow 1, 3, 12, 13, 14, 17, 34, 35, 37, 55, 74, 81, 83, 93, 94, 95, 97, 108, 109, 110, 137, 138, 139, 153, 154, 155, 157, 166, 167, 168, 180, 185, and 193.

[0030] Examples of black pigments include Pigment Black 7, 28, and 26.

[0031] Examples of white pigments include titanium dioxide and the like.

[0032] From the viewpoint of improving dispersibility in the ink, the pigment is preferably further dispersed with a pigment dispersant, which will be described later.

[0033] The pigment may also be a self-dispersing pigment. A self-dispersing pigment is a pigment particle whose surface is modified with a group having a hydrophilic group, and has pigment particles and hydrophilic groups bonded to the surface of the pigment particles.

[0034] Examples of hydrophilic groups include carboxyl groups, sulfonic acid groups, and phosphorus-containing groups, and examples of phosphorus-containing groups include phosphoric acid groups, phosphonic acid groups, phosphinic acid groups, phosphite groups, and phosphate groups.

[0035] Examples of commercially available self-dispersing pigments include Cabot Corporation's Cab-0-Jet (registered trademark) 200K, 250C, 260M, and 270V (sulfonic acid group-containing self-dispersing pigments), Cab-0-Jet (registered trademark) 300K (carboxylic acid group-containing self-dispersing pigments), and Cab-0-Jet (registered trademark) 400K, 450C, 465M, 470V, and 480V (phosphate group-containing self-dispersing pigments).

[0036] The pigment content is not particularly limited, but from the viewpoint of easily adjusting the viscosity of the inkjet ink appropriately and enabling the formation of high-density images, it is preferably 0.3 to 10% by mass, and more preferably 0.5 to 3% by mass, of the inkjet ink. When the pigment content is equal to or greater than the lower limit, the color of the image tends to be more vivid. When the pigment content is equal to or less than the upper limit, the viscosity of the inkjet ink does not become too high, and ejection stability is less likely to be impaired.

[0037] (fixing resin) The fixing resin is included for the purpose of fixing the fixing layer to the fabric, and the fixing of the fixing layer also fixes the pigment. The fixing resin may be, for example, a water-dispersible resin. From the viewpoint of preventing the fabric from hardening even after image formation and maintaining a good texture, the fixing resin preferably has a low glass transition temperature Tg. Specifically, the Tg of the fixing resin is preferably −35° C. or lower, and more preferably −35 to −70° C. The Tg of the fixing resin can be measured by differential scanning calorimetry in accordance with JIS K 7121 at a temperature rise rate of 10° C. / min.

[0038] The Tg of the fixing resin can be adjusted by the type of fixing resin and the monomer composition. For example, in the case of a (meth)acrylic resin, increasing the content of the structural unit (a) derived from alkyl acrylate tends to lower the Tg.

[0039] The type of fixing resin is not particularly limited as long as its Tg satisfies the above range. Examples of fixing resins include (meth)acrylic resins, polyurethane resins, polyester resins, etc. Among them, (meth)acrylic resins and polyurethane resins are preferred from the viewpoint of having good flexibility and being able to more easily maintain the texture of the fabric. In this specification, (meth)acrylic refers to acrylic, methacrylic, or both.

[0040] The fixing resin may also have an ionic group. The ionic group of the fixing resin may be an ionic group that forms a pair with the ionic group of the pretreatment liquid attached to the fabric. For example, since the pretreatment liquid usually has a cationic group, the fixing resin contained in the inkjet ink may have an anionic group. Examples of the anionic group include a carboxyl group, a sulfonic acid group, and a phosphonic acid group.

[0041] A (meth)acrylic resin is a polymer containing structural units derived from a (meth)acrylic monomer.

[0042] The (meth)acrylic monomer is a monomer having a (meth)acryloyl group, and examples thereof include (meth)acrylic acid, (meth)acrylic acid alkyl esters, (meth)acrylamides, etc. Note that (meth)acrylic is a concept that includes both methacryl and acrylic. Among them, (meth)acrylic acid alkyl esters are preferred.

[0043] That is, the (meth)acrylic resin contains a structural unit (a) derived from a (meth)acrylic acid alkyl ester, and from the viewpoint of improving water dispersibility and coagulation properties, it is preferable that the (meth)acrylic resin further contains a structural unit (b) derived from an unsaturated compound having an anionic group.

[0044] The structural unit (a) is derived from a (meth)acrylic acid alkyl ester. From the viewpoint of lowering the Tg of the resin, the (meth)acrylic acid alkyl ester preferably includes an acrylic acid alkyl ester. The number of carbon atoms in the alkyl group of the acrylic acid alkyl ester is, for example, 1 to 20, preferably 4 to 12, and more preferably 4 to 8. Examples of the acrylic acid alkyl ester include butyl acrylate, pentyl acrylate, hexyl acrylate, heptyl acrylate, and 2-ethylhexyl acrylate, and butyl acrylate is preferred.

[0045] The (meth)acrylic acid alkyl ester may be used alone or in combination of two or more kinds, for example, an acrylic acid alkyl ester and a methacrylic acid alkyl ester may be used in combination.

[0046] The content of the structural unit (a) is not particularly limited, but is preferably 70 to 96% by mass relative to all structural units constituting the (meth)acrylic resin. When the content is 70% by mass or more, the Tg of the resin is likely to be lowered. When the content is 96% by mass or less, properties such as abrasion resistance are less likely to be impaired. From the same viewpoint, the content is more preferably 80 to 90% by mass relative to all structural units constituting the (meth)acrylic resin.

[0047] The structural unit (b) is derived from an unsaturated compound having an anionic group. Examples of unsaturated compounds having a carboxy group include ethylenically unsaturated carboxylic acids such as acrylic acid, methacrylic acid, crotonic acid, itaconic acid, maleic acid, fumaric acid, and 2-acryloyloxyethyl succinic acid. Examples of unsaturated compounds having a sulfonic acid group include vinyl sulfonic acid, styrene sulfonic acid, and allyl sulfonic acid. Examples of unsaturated compounds having a phosphoric acid group include vinyl phosphonic acid and 2-((meth)acryloyloxy)ethyl phosphate. Among these, ethylenically unsaturated carboxylic acids are preferred.

[0048] The content of the structural unit (b) is not particularly limited, but is preferably 3 to 15% by mass relative to all structural units constituting the (meth)acrylic resin. When the content is 3% by mass or more, the dispersibility and coagulation of the fixing resin in the ink are more likely to be improved. When the content is 15% by mass or less, the viscosity of the ink is less likely to increase, and the ejection stability is less likely to be impaired. From the same viewpoint, the content of the structural unit (b) is more preferably 3 to 10% by mass relative to all structural units constituting the (meth)acrylic resin.

[0049] The (meth)acrylic resin may further contain a structural unit (c) derived from a monomer other than those mentioned above. Examples of such other monomers include monofunctional monomers such as ethylenically unsaturated carboxylic acids (e.g., maleic acid, itaconic acid), styrenes (e.g., styrene, α-methylstyrene, vinyltoluene), saturated vinyl fatty acids (e.g., vinyl acetate, vinyl propionate), vinyl compounds (e.g., 1,4-divinyloxybutane, divinylbenzene, etc.), allyl compounds (e.g., diallyl phthalate, triallyl cyanurate, etc.), and acrylamide; and difunctional or higher functional monomers such as polyfunctional (meth)acrylates (e.g., diethylene glycol di(meth)acrylate, 1,6-hexanediol di(meth)acrylate, propylene glycol di(meth)acrylate, N,N'-methylenebis(acrylamide), etc.), and polyfunctional acrylamide.

[0050] Examples of commercially available (meth)acrylic resins include EMN-325 (Acrylate, manufactured by Nippon Shokubai Co., Ltd., acrylic elastomer, Tg: -50°C) and EMN-326 (Acrylate, manufactured by Nippon Shokubai Co., Ltd., acrylic elastomer, Tg: -50°C).

[0051] The urethane resin is a thermoplastic urethane resin. The thermoplastic urethane resin may be, for example, a reaction product of a low-molecular-weight diol as a chain extender, a polyisocyanate, and a polyol. The urethane resin is preferably a self-emulsifying type. The self-emulsifying urethane resin may be, for example, a reaction product of a low-molecular-weight diol as a chain extender, a polyisocyanate having an anionic group, and a polyol.

[0052] The low molecular weight diol is a difunctional aliphatic oligomer of glycol. Typical difunctional aliphatic oligomers of glycol include, for example, ethylene glycol, propylene glycol, 1,4 butanediol, and 1,6 hexanediol.

[0053] The polyisocyanate is preferably a diisocyanate, and examples thereof include aromatic diisocyanates such as diphenylmethane diisocyanate, for example, 4,4'-diphenylmethane diisocyanate, 2,4'-diphenylmethane diisocyanate, and aliphatic diisocyanates such as 4,4'-dicyclohexylmethane diisocyanate, 2,4'-dicyclohexylmethane diisocyanate.

[0054] The polyol may be a polyester polyol or a polyether polyol. Examples of polyester polyols include the reaction product of a polycarboxylic acid and a polyol. Examples of polycarboxylic acids include malonic acid, citric acid, succinic acid, glutaric acid, adipic acid, pimelic acid, azelaic acid, sebacic acid, maleic acid, fumaric acid, terephthalic acid, and phthalic acid. Examples of polyols to be reacted with the polycarboxylic acid include trimethylolpropane, trimethylolethane, 2-methyl glucoside, sorbitol, and low-molecular-weight polyols such as polyoxyethylene glycol, polyoxypropylene glycol, and block heteropolyoxyethylene-polyoxypropylene glycol.

[0055] Thermoplastic polyurethanes contain hard and soft segments in their molecules. The hard segments are primarily formed by the reaction of polyisocyanate with low molecular weight diols; the soft segments are primarily formed by the reaction of polyols.

[0056] The mass ratio of the hard segment to the soft segment in the polymer chain of the thermoplastic polyurethane is, for example, 75 / 25 to 15 / 85 (mass ratio), preferably 60 / 40 to 25 / 75 (mass ratio). From the viewpoint of lowering Tg, the mass ratio of the soft segment may be increased, for example, the mass ratio of the soft segment may be higher than that of the hard segment.

[0057] An example of a commercially available thermoplastic polyurethane product is Elastollan 1185A (manufactured by BASF, thermoplastic polyurethane elastomer, Tg: -41°C).

[0058] The acid value of the fixing resin is not particularly limited, but from the viewpoint of further improving the abrasion resistance, it is preferably 15 to 100 mgKOH / g, and more preferably 20 to 80 mgKOH / g. The acid value of the fixing resin can be measured in accordance with JIS K 0070.

[0059] The acid value of the fixing resin can be adjusted by the content of the structural unit (b). For example, the acid value increases when the content of the structural unit (b) derived from an unsaturated compound having an acidic group is increased.

[0060] The average particle size of the fixing resin in the inkjet ink is not particularly limited, but is preferably 30 to 200 nm, more preferably 50 to 120 nm, from the viewpoint of, for example, inkjet ejection properties. The average particle size is the average value of primary particle sizes. The average particle size can be measured as the dispersed particle size (Z average) using, for example, a Zataizer Nano S90 manufactured by Melvern.

[0061] The weight-average molecular weight (Mw) of the fixing resin is not particularly limited. However, from the viewpoint of improving, for example, the abrasion resistance, the weight-average molecular weight of the fixing resin is preferably high, for example, 10,000 to 1,000,000. On the other hand, from the viewpoint of more easily improving the texture, the weight-average molecular weight of the fixing resin is preferably low, preferably 10,000 or less. The weight-average molecular weight of the fixing resin can be measured in polystyrene equivalent terms by gel permeation chromatography. In particular, when the weight-average molecular weight of the fixing resin is low, such as 10,000 or less, the resin is likely to adhere to the nozzle surface of the inkjet recording head. Even in such cases, the addition of a surfactant can reduce resin adhesion.

[0062] The content of the fixing resin is not particularly limited, but is preferably 1 to 20% by mass relative to the inkjet ink. When the content of the fixing resin is 1% by mass or more, the fixation of the inkjet ink to fabric is more easily improved. When the content of the fixing resin is 20% by mass or less, the texture is less likely to be impaired. From the same viewpoint, the content of the fixing resin is more preferably 5 to 15% by mass relative to the ink.

[0063] (surfactant) The surfactant may be added mainly for the purpose of suppressing adhesion of the fixing resin to the nozzle surface of the recording head from which the inkjet ink is ejected. There are no particular limitations on the surfactant as long as it has affinity with the fixing resin. Such a surfactant is preferably a nonionic surfactant.

[0064] Nonionic surfactants are surfactants that do not contain ionic groups. Examples of nonionic surfactants include: Acetylene glycol surfactants such as acetylene glycol and ethylene oxide and / or propylene oxide adducts of acetylene glycol (for example, 2,4,7,9-tetramethyl-5-decyne-4,7-diol, 3,6-dimethyl-4-octyne-3,6-diol, etc., and their ethylene oxide and / or propylene oxide adducts); Acetylenic alcohol surfactants such as acetylene alcohol, ethylene oxide and / or propylene oxide adducts of acetylene alcohol (for example, 3,5-dimethyl-1-hexane-3-ol, etc., and its ethylene oxide and / or propylene oxide adducts): Ether surfactants such as polyoxyethylene nonylphenyl ether, polyoxyethylene octylphenyl ether, polyoxyethylene dodecylphenyl ether, polyoxyethylene alkyl allyl ether, polyoxyethylene oleyl ether, polyoxyethylene lauryl ether, polyoxyethylene alkyl ether, and polyoxyalkylene alkyl ether; Ester surfactants such as polyoxyethylene oleic acid, polyoxyethylene oleate, polyoxyethylene distearate, sorbitan laurate, sorbitan monostearate, sorbitan monooleate, sorbitan sesquioleate, polyoxyethylene monooleate, and polyoxyethylene stearate; polyether-modified siloxane surfactants such as dimethylpolysiloxane; Examples include fluorine-containing surfactants such as fluorine alkyl esters and perfluoroalkyl carboxylates.

[0065] These surfactants may be commercially available. For example, commercially available examples of polyether-modified siloxane compounds include TEGO Wet240, TEGO WetKL245, TEGO Wet250, TEGO Wet260, TEGO Wet265, and TEGO Wet280 manufactured by Evonik Corporation, and LPX23288, LPX23289, LPX23347, BYK-348, and BYK-349 manufactured by BYK. Commercially available examples of acetylene glycol surfactants and acetylene alcohol surfactants include Olfine E1010, Olfine EXP.4036, Olfine EXP.4123, Surfynol 465, and Surfynol 485 manufactured by Nissin Chemical Industry Co., Ltd. Examples of commercially available ether surfactants include Emulgen 106 (polyoxyethylene lauryl ether) and Emulgen 709 (polyoxyethylene higher alkyl ether) manufactured by Kao Corporation, and DYNWET800 and DYNWET800N (both alcohol alkoxylates) manufactured by BYK.

[0066] Among these, acetylene glycol surfactants and acetylene alcohol surfactants are preferred, and ethylene oxide adducts of acetylene glycol are more preferred, from the viewpoint of having better affinity with water-dispersible resins and being more likely to prevent the resin from adhering to the head.

[0067] The content of the surfactant is preferably 0.1 to 10% by mass relative to the inkjet ink. When the content of the surfactant is 0.1% by mass or more, adhesion of the resin to the head is more easily suppressed. When the content of the surfactant is 10% by mass or less, the abrasion resistance of the resulting image-formed product is less likely to be impaired. From this perspective, the content of the surfactant is more preferably 0.1 to 5% by mass relative to the ink.

[0068] (aqueous medium) The aqueous medium is not particularly limited, but preferably contains water and further contains a water-soluble organic solvent.

[0069] The water content is, for example, 20 to 70% by mass, and preferably 30 to 60% by mass, based on the inkjet ink.

[0070] The water-soluble organic solvent is not particularly limited as long as it is compatible with water, but from the viewpoint of facilitating penetration of the inkjet ink into the interior of the fabric and preventing loss of ejection stability in the inkjet method, it is preferable that the inkjet ink does not easily thicken upon drying. Therefore, it is preferable that the inkjet ink contains a high-boiling point solvent with a boiling point of 200°C or higher.

[0071] The high boiling point solvent having a boiling point of 200° C. or higher may be any water-soluble organic solvent having a boiling point of 200° C. or higher, and is preferably a polyol or a polyalkylene oxide.

[0072] Examples of polyols with a boiling point of 200°C or higher include dihydric alcohols such as 1,3-butanediol (boiling point 208°C), 1,6-hexanediol (boiling point 223°C), and polypropylene glycol; and trihydric or higher alcohols such as glycerin (boiling point 290°C) and trimethylolpropane (boiling point 295°C).

[0073] Examples of polyalkylene oxides having a boiling point of 200°C or higher include ethers of dihydric alcohols such as diethylene glycol monoethyl ether (boiling point 202°C), triethylene glycol monomethyl ether (boiling point 245°C), tetraethylene glycol monomethyl ether (boiling point 305°C), tripropylene glycol monoethyl ether (boiling point 256°C), and polypropylene glycol, as well as ethers of trihydric or higher alcohols such as glycerin (boiling point 290°C) and hexanetriol.

[0074] The aqueous medium may further contain a solvent other than the high-boiling point solvent. Examples of the other solvent include polyhydric alcohols having a boiling point of less than 200°C (e.g., ethylene glycol, propylene glycol, hexanetriol, etc.); polyhydric alcohol ethers having a boiling point of less than 200°C (e.g., ethylene glycol monomethyl ether, ethylene glycol monobutyl ether, diethylene glycol monomethyl ether, diethylene glycol dimethyl ether, propylene glycol monomethyl ether, propylene glycol monoethyl ether); monohydric alcohols (e.g., methanol, ethanol, propanol, pentanol, hexanol, cyclohexanol, butyl alcohol, etc.); benzyl alcohol); amines (e.g., ethanolamine, N-ethyldiethanolamine, morpholine, N-ethylmorpholine, ethylenediamine, diethylenediamine, triethylenetetramine); amides (e.g., formamide, N,N-dimethylformamide, N,N-dimethylacetamide); heterocycles (e.g., 2-pyrrolidone, N-methyl-2-pyrrolidone, N-cyclohexyl-2-pyrrolidone, 2-oxazolidone, 1,3-dimethyl-2-imidazolidine), sulfoxides (e.g., dimethyl sulfoxide); and sulfones (e.g., sulfolane).

[0075] The content of the water-soluble organic solvent is, for example, 20 to 70% by mass, and preferably 30 to 60% by mass, based on the inkjet ink.

[0076] (Other ingredients) The inkjet ink may further contain other components as necessary, such as pigment dispersants, preservatives, antifungal agents, and pH adjusters.

[0077] The pigment dispersant is present in the ink so as to surround the surface of the pigment particle or is adsorbed to the surface of the pigment particle to form a pigment dispersion, thereby dispersing the pigment well. The pigment dispersant is preferably a polymer dispersant, more preferably an anionic polymer dispersant.

[0078] The anionic polymer dispersant is a polymer dispersant having a hydrophilic group such as a carboxylic acid group, a phosphorus-containing group, or a sulfonic acid group, and is preferably a polymer dispersant having a carboxylic acid group.

[0079] The polymer dispersant having a carboxylic acid group may be a polycarboxylic acid or a salt thereof. Examples of polycarboxylic acids include (co)polymers of monomers selected from acrylic acid or its derivatives, maleic acid or its derivatives, itaconic acid or its derivatives, and fumaric acid or its derivatives, and salts thereof. Examples of other monomers that may form the copolymer include styrene and vinylnaphthalene.

[0080] From the viewpoint of sufficiently dispersing pigment particles, the anionic group equivalent of the anionic polymer dispersant is preferably, for example, 1.1 to 3.8 meq / g. When the anionic group equivalent is within the above range, high pigment dispersibility is easily obtained without increasing the molecular weight of the anionic polymer dispersant. The anionic group equivalent of the anionic polymer dispersant can be determined from the acid value. The acid value can be measured in accordance with JIS K0070.

[0081] The weight average molecular weight (Mw) of the polymer dispersant is not particularly limited, but is preferably 5,000 to 30,000. When the Mw of the polymer dispersant is 5,000 or more, the pigment particles can be easily dispersed sufficiently, and when it is 30,000 or less, the ink does not thicken too much, so that the penetration into the fabric is less likely to be impaired. The Mw of the polymer dispersant can be measured by the same method as above.

[0082] The content of the polymer dispersant is not particularly limited as long as it is in a range that sufficiently disperses the pigment particles and has a viscosity that does not impair the permeability into the fabric, but it is preferably 20 to 100% by mass, and more preferably 25 to 60% by mass, relative to the pigment.

[0083] Examples of the preservative or antifungal agent include aromatic halogen compounds (eg, Preventol CMK), methylene dithiocyanate, halogen-containing nitrogen-sulfur compounds, 1,2-benzisothiazolin-3-one (eg, PROXEL GXL), and the like.

[0084] Examples of pH adjusters include citric acid, sodium citrate, hydrochloric acid, and sodium hydroxide.

[0085] (Physical Properties) The viscosity of the inkjet ink at 25°C is not particularly limited as long as it provides good ejection properties using an inkjet method, but is preferably 3 to 20 mPa·s, and more preferably 4 to 12 mPa·s. The viscosity of the ink can be measured at 25°C using an E-type viscometer.

[0086] (Preparation of Inkjet Inks) The inkjet ink can be produced by any method. For example, the inkjet ink can be produced by 1) mixing a pigment, a pigment dispersant, and a solvent (such as water) to obtain a pigment dispersion, and 2) further mixing the obtained pigment dispersion with a dispersion containing the water-dispersible resin (resin particle dispersion) and an aqueous medium.

[0087] 1-3. Overcoat layer forming liquid The overcoat layer-forming solution is applied onto the pretreatment layer and the fixing layer to form an overcoat layer, which can suppress stickiness caused by the pretreatment layer and the fixing layer.

[0088] The overcoat layer forming liquid contains anionic resin particles. From the viewpoint of suppressing stickiness of the printed image and deterioration of the texture of the fabric (image-formed product) on which the printed image is formed, the anionic resin particles preferably have a glass transition temperature Tg of 50°C or higher, more preferably 100°C or higher. The glass transition temperature Tg of the anionic resin particles can be measured by differential scanning calorimetry in accordance with JIS K 7121 at a temperature rise rate of 10°C / min.

[0089] Examples of anionic resin particles include polymer particles having functional groups capable of carrying a negative charge, such as carboxyl groups, hydroxyl groups, and sulfate groups.

[0090] Examples of commercially available anionic resin particles include AQUACER 507 manufactured by BYK and Hitec E-4A manufactured by Toho Chemical Industry Co., Ltd.

[0091] The content of the anionic resin particles in the overcoat layer forming liquid is preferably 2% by mass to 6% by mass, and more preferably about 4% by mass.

[0092] The method for applying the overcoat layer forming liquid is not particularly limited and may be, for example, a pad method, a coating method, a spray method, an inkjet method, etc. The overcoat layer forming liquid applied to the fabric may be heated and dried using hot air, a hot plate, or a heat roller.

[0093] 2. Image forming apparatus and image forming method 2-1. Image forming device An image forming apparatus used to form a textile image according to the present invention will be outlined below.

[0094] FIG. 1 is a schematic diagram showing an outline of an embodiment of an image forming apparatus 100 used to form a textile image. As shown in FIG. 1, the image forming apparatus 100 includes a pretreatment liquid storage section 110a, an ink storage section 110b, an overcoat layer forming liquid storage section 110c, a recording head 120, a head carriage 130, a drying section 140, and a transport section 150.

[0095] The pretreatment liquid storage section 110a, the ink storage section 110b, and the overcoat layer forming liquid storage section 110c store a pretreatment liquid a, an inkjet ink b, and an overcoat layer forming liquid c, respectively, and are arranged in this order from the upstream to the downstream direction in the transport direction Y of the fabric 160. The fabric 160 is transported by a transport section 150.

[0096] The pretreatment liquid storage section 110a, the ink storage section 110b, and the overcoat layer forming liquid storage section 110c supply the pretreatment liquid a, the inkjet ink b, and the overcoat layer forming liquid c to the recording heads 120 connected to them, and the recording heads 120 eject the pretreatment liquid a, the inkjet ink b, and the overcoat layer forming liquid c onto the fabric 160, respectively, to form a printed image.

[0097] A plurality of ink containing sections 110b and recording heads 120 may be arranged, for example, for each ink color.

[0098] The head carriage 130 carries the recording head 120 and scans the recording head 120 in a main scanning direction that is substantially perpendicular to the transport direction Y of the fabric 160. The recording head 120 may move integrally with the ink containing section 110b or may move separately.

[0099] The drying unit 140 is disposed downstream of each storage unit and each recording head 120 in the transport direction Y. The drying unit 140 may be a heating unit such as a hot air dryer that blows hot air, a heater that irradiates infrared rays or ionizing radiation, or a heating roller. The drying unit 140 dries the printed image formed on the fabric 160.

[0100] 2-2. Image forming method Next, a method for producing a printed image formed product will be specifically described with reference to Fig. 1. The method for producing a printed image formed product according to this embodiment includes 1) a step of ejecting a pretreatment liquid, an inkjet ink, and an overcoat layer forming liquid from the recording heads 120 onto a fabric in this order and adhering them to the fabric to form a printed image, and 2) a step of drying and fixing the printed image.

[0101] Step 1) First, a pretreatment liquid, an inkjet ink, and an overcoat layer forming liquid are ejected in this order from each recording head 120 to form a pretreatment layer on the fabric 160 moving in the transport direction Y, a fixing layer is formed thereon, and an overcoat layer is formed thereon to form a textile print image.

[0102] Step 2) Next, the printed image formed on the fabric 160 is dried in the drying section 140 to remove the solvent component in the ink, thereby fixing the pigment to the fabric 160. In this way, a printed image is obtained.

[0103] The drying method is not particularly limited, and may be a method using a heater, a hot air dryer, a heated roller, etc. In this embodiment, it is preferable that the drying unit 140 uses a hot air dryer and a heater to heat and dry both sides of the fabric.

[0104] The drying temperature may be set so as to evaporate the solvent component in the ink. Specifically, the drying temperature is preferably equal to or higher than the temperature at which the solvent component evaporates, and equal to or lower than a temperature 170°C higher than the glass transition temperature Tg of the fixing resin (Tg + 170°C or lower). The drying temperature may also be room temperature.

[0105] 2-3. Image evaluation The printed image according to this embodiment prevents deterioration of the texture of the fabric and also prevents stickiness of the printed image. Specifically, the texture is evaluated by the small difference in bending torque force in a bending test between a fabric on which a printed image has been formed under specified conditions and a fabric before the printed image has been formed. From the viewpoint of improving the texture of the fabric on which the printed image has been formed, the difference in bending torque is preferably 0.006 gf·cm or less, more preferably 0.004 gf·cm or less, and even more preferably 0.002 gf·cm or less.

[0106] The bending test can be carried out in the following manner: Figure 2 is a schematic diagram showing an outline of the bending test. 1) First, the pretreatment liquid, inkjet ink, and overcoat layer forming liquid are applied onto the fabric. At this time, the adhesion amount of the fixing layer formed by the inkjet ink is 3 g / m. 2 ~10g / m 2An image is formed so that the image is printed, and then dried to obtain a printed image. The fabric on which the image is formed (printed image) is cut into a size of 5 x 20 cm to be used as sample piece 1. Next, as shown in Figure 2, one end A in the length direction of sample piece 1 and a position B 3 cm away from the end are clamped by clips of a bending tester. Then, the end A is rotated with position B as the base point, and the curvature of sample piece 1 near position B is adjusted to 2.5 cm. -1 The force required to bend the fabric (printed image-formed product) until the printed image is bent is measured. 2) A similar test is also carried out on a fabric (5 x 20 cm sample piece) on which no image is formed (bending torque of the white part). 3) The bending torque value obtained in 2) above is subtracted from the bending torque value obtained in 1) above to calculate the bending torque difference.

[0107] As a bending tester, for example, a KES-FB2-A pure bending tester (Kato Tech) can be used. The "amount of printed image adhered" can be determined by subtracting the weight of the fabric on which the printed image is not formed from the weight of the product on which the printed image is formed (the fabric on which the printed image is formed).

[0108] The difference in bending torque can be adjusted by adjusting the amount and type of fixing resin, assuming a constant amount of pigment attached. For example, the lower the Tg of the fixing resin, the smaller the difference in bending torque. Also, the smaller the amount of fixing resin, the smaller the difference in bending torque.

[0109] Furthermore, the printed image according to this embodiment is suppressed from becoming sticky. Specifically, stickiness is evaluated by a small difference in the mean coefficient of friction MIU between a fabric on which a printed image is formed under predetermined conditions and a fabric on which no printed image is formed, and a small difference in the mean deviation of the mean coefficient of friction MMD. From the viewpoint of suppressing stickiness, the difference in the mean coefficient of friction MIU is preferably 0.42 or less, more preferably 0.35 or less, and even more preferably 0.3 or less. From the same viewpoint, the difference in the mean deviation of the mean coefficient of friction MMD is preferably 0.24 or less, more preferably 0.2 or less, and even more preferably 0.15 or less.

[0110] The difference in the mean coefficient of friction MIU and the difference in the mean deviation of the mean coefficient of friction MMD can be measured as follows.

[0111] Measurements can be made using a friction tester KES-SE (manufactured by Kato Tech Co., Ltd.). A fabric without a printed image and a fabric with a printed image are used as samples, and the average coefficient of friction MIU and the mean deviation of the average coefficient of friction MMD are measured for each. Specifically, the sample is placed on the sample stage of the friction tester, and a contactor with a contact surface of 1 cm is used as the contactor that comes into contact with the sample. 2 A piano wire sensor is used. A load of 50g is applied to the contact, and the contact moves back and forth at a distance of 30mm. The measurement environment can be an air temperature of 23°C and a humidity of 65%. By calculating the difference between the respective measurement results, the difference in the mean coefficient of friction MIU and the difference in the mean deviation of the mean coefficient of friction MMD can be calculated. [Example]

[0112] The present invention will be specifically explained below with reference to examples, but the present invention is not limited to these examples.

[0113] Example 1 The pretreatment liquid, inkjet ink, and overcoat layer-forming liquid used to obtain the printed image of Example 1 were prepared as follows.

[0114] 1-1. Pretreatment solution The pre-treatment liquid was obtained by mixing the following components in the following proportions, with the mass of the pre-treatment liquid being 100 parts by mass. As a cationic resin, PAS-H-1L (manufactured by Nitto-Beau Medical Co., Ltd.): 4.7 parts by mass Ethylene glycol: 10 parts by mass Propylene glycol: 10 parts by mass Glycerin: 10 parts by mass: Surfactant E-1010: 0.1 parts by mass Proxel GXL (manufactured by Lonza Japan, 1,2-benzisothiazolin-3-one, antifungal agent): 0.10 parts by mass Ion-exchanged water: Remaining

[0115] 1-2. Inkjet ink The inkjet ink contains a pigment (pigment dispersion), a fixing resin, a surfactant, a water-soluble organic solvent, and an antifungal agent. Each of these components was prepared as follows.

[0116] A neutralized pigment dispersant was prepared by mixing 7 parts of styrene-butyl acrylate-methacrylic acid copolymer (anionic dispersant, weight-average molecular weight 16,000, anionic group equivalent weight 3.5 meq / g) with 78 parts of water and warming and stirring. To this mixture was added 15 parts of CI Pigment Blue 15:3, premixed, and dispersed using a sand grinder filled with 50% 0.5 mm zirconia beads to obtain a cyan pigment dispersion with a pigment concentration of 15% by volume. As the fixing resin, EMN-325 (manufactured by Nippon Shokubai Co., Ltd., Tg -50°C) was used. As the surfactant, E-1010 (manufactured by Nissin Chemical Industry Co., Ltd.) was used. As the water-soluble organic solvents, ethylene glycol (boiling point 197°C), glycerin (boiling point 290°C), and propylene glycol (boiling point 188°C) were used. Proxel GXL (Lonza Japan, 1,2-benzisothiazolin-3-one) was used as the fungicide.

[0117] The inkjet ink was obtained by mixing the above components in the following proportions, with the mass of the inkjet ink being 100 parts by mass. Pigment dispersion: 10 parts by weight (pigment concentration 15% by weight, solid content concentration 1.5 parts by weight) Fixing resin: 10 parts by weight Ethylene glycol: 10 parts by mass Propylene glycol: 10 parts by mass Glycerin: 10 parts by mass: Surfactant: 0.5 parts by mass Proxel GXL (manufactured by Lonza Japan, 1,2-benzisothiazolin-3-one, antifungal agent): 0.10 parts by mass Ion-exchanged water: Remaining

[0118] 1-3. Overcoat layer forming liquid The overcoat layer forming liquid was obtained by mixing the following components in the following proportions, with the mass of the overcoat layer forming liquid being 100 parts by mass. Anionic resin fine particles: AQUACER 507 (manufactured by BYK): 10 parts by mass Ethylene glycol: 10 parts by mass Propylene glycol: 10 parts by mass Glycerin: 10 parts by mass: Surfactant E-1010: 0.1 parts by mass Proxel GXL (manufactured by Lonza Japan, 1,2-benzisothiazolin-3-one, antifungal agent): 0.10 parts by mass Ion-exchanged water: Remaining

[0119] 2.Textile printing image formation Cotton satin (100% cotton: product name 60 Cotton Satin, manufactured by Okadaya Co., Ltd.) was prepared as the fabric. The above-mentioned pretreatment liquid, inkjet ink, and overcoat layer forming liquid were applied to this cotton satin by inkjet printing, and then dried to obtain a printed image. A Konica Minolta head #204 was used as the recording head. The pretreatment liquid, inkjet ink, and overcoat layer forming liquid were ejected from the recording head at a main scanning speed of 540 dpi and a sub-scanning speed of 720 dpi. dpi represents the number of ink droplets (dots) per 2.54 cm. The ejection frequency was 22.4 kHz. The fabric was then dried at 120°C for 5 minutes in a belt-conveying dryer to obtain a printed image. The deposition mass of the pretreatment layer, fixing layer, and overcoat layer was 1 g / m. 2 , 6g / m 2 , 3g / m 2 This amount of adhesion was calculated from the amount of ink ejected.

[0120] 3. Evaluation The stickiness and texture of the printed image were evaluated as follows.

[0121] (sticky) The stickiness of the obtained printed image was evaluated by measuring the difference in the average coefficient of friction MIU as follows. 1) The MIU was measured using a friction tester KES-SE (manufactured by Kato Tech Co., Ltd.). A fabric without a printed image and a fabric with a printed image were used as samples, and the average coefficient of friction MIU was measured for each. Specifically, each sample was placed on the sample stage of the friction tester, and a contactor with a contact surface of 1 cm was used as the contactor that came into contact with the sample. 2 A piano wire sensor was used. A load of 50 g was applied to the contact, and the contact was moved back and forth over a distance of 30 mm. The measurement environment was an air temperature of 23°C and a humidity of 65%. The difference in average friction coefficients MIU was calculated by subtracting the average friction coefficient MIU of the fabric without the printed image from the average friction coefficient MIU of the product with the printed image. 2) The difference in the average friction coefficient MIU was evaluated according to the following criteria. ◎: MIU difference less than 0.35 ○: MIU difference 0.35 or more and 0.42 or less △: MIU difference: over 0.42 and less than 0.5 ×: MIU difference > 0.5

[0122] (Texture) The texture of the resulting printed image-formed product was evaluated by the following bending test. 1) The fabric on which the printed image was formed was cut into a size of 5 x 20 cm to form sample piece 1. Next, as shown in Figure 2, one end A in the longitudinal direction of sample piece 1 and a position B 3 cm away from the end were clamped by the clips of a bending tester KES-FB2-A pure bending tester (Kato Tech). Then, the end A was rotated with position B as the base point, and the curvature of sample piece 1 near position B was adjusted to 2.5 cm. -1 The force required to bend the image forming section until the sheet reached the bending point (bending torque of the image forming section) was measured. 2) A similar test was also carried out on a fabric (5×20 cm sample piece) on which no image was formed (bending torque of the white part). 3) The difference in bending torque obtained in 1) and 2) above was calculated. The texture was then evaluated according to the following criteria. ○: The difference in bending torque is 0.006 gf cm or less ×: The difference in bending torque is more than 0.006 gf cm

[0123] The evaluation results are shown in Table 1.

[0124] (Examples 2 to 5, Comparative Examples 1 and 2) Printed image-formed products of Examples 2 to 5 and Comparative Example 1 were produced and evaluated in the same manner as in Example 1, except that the cationic resin contained in the pretreatment liquid was changed as shown in Table 1. In Comparative Example 2, a printed image-formed product was produced and evaluated in the same manner as in Example 1, except that no pretreatment liquid was used.

[0125] [Table 1]

[0126] Examples 1 to 5 all exhibited good stickiness suppression and texture, whereas Comparative Example 1 exhibited poor results. This is thought to be because the weight-average molecular weight (Mw) of the cationic resin was 1,000 or more in Examples 1 to 5, whereas it was less than 1,000 in Comparative Example 1. It is thought that using a cationic resin with a weight-average molecular weight of less than 1,000 in this way can cause stickiness in printed images.

[0127] On the other hand, when no pretreatment liquid and no cationic resin are used, as in Comparative Example 2, the stickiness of the printed image is improved, but the texture remains poor. Thus, when attempting to achieve both, it has been found that using a pretreatment liquid containing a cationic resin with a weight-average molecular weight of 1,000 or more is effective. [Industrial Applicability]

[0128] According to the present invention, it is possible to obtain a printed image formed on a textile with a good texture while suppressing stickiness. Therefore, the present invention is expected to broaden the scope of the textile image forming technology and contribute to the advancement and spread of technology in this field.
