Description

[Technical field]

[0001] The present invention relates to a transfer recording method. [Background technology]

[0002] A transfer printing method is known in which a transfer sheet, which is a transfer medium on which an image has been formed, is superimposed on a fabric such as a cloth, and the image is transferred to the fabric by applying heat and pressure. In such a method, an inkjet method is often used when forming an image on the transfer sheet, since it is advantageous in forming a fine image with high on-demand performance.

[0003] In the above-mentioned transfer printing method, a typical method involves forming an image on a transfer sheet having a release layer and a hot melt layer formed on the entire surface of a substrate, and then heating and pressing the transfer sheet onto a fabric to transfer the image.

[0004] Patent Document 1 discloses a method for producing a transfer medium, which includes a colored layer forming step of ejecting ink from an inkjet head toward a substrate to form a colored layer on the substrate, and an adhesive layer forming step of ejecting an adhesive liquid from an inkjet head toward the colored layer to form an adhesive layer on the colored layer, and in the colored layer forming step, a white ink is applied so as to cover the surface of an image of CMYK ink. This document describes that when the ink is a water-based ink for forming an image, a colored layer pattern can be obtained with high resolution and good transferability by evaporating 65 to 95% by mass of the liquid components contained in the ink.

[0005] [Patent Document 1] JP 2012-126025 A Summary of the Invention [Problem to be solved by the invention]

[0006] In the technology of Patent Document 1, plastic or metal is used as the transfer material. However, when using fabric, the transfer conditions that allow suitable transfer have not been sufficiently examined. In addition, since the amount of ink attached to a transfer pattern that requires high resolution is usually different for each area, it is difficult to suitably adjust the evaporation rate of the liquid component in all areas. Therefore, a method that can record with high image quality regardless of the evaporation rate of the liquid component has been required. [Means for solving the problem]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] The following describes an embodiment of the present invention. The embodiment described below is an example of the present invention. The present invention is not limited to the following embodiment, and includes various modified forms that are implemented within the scope of the present invention. Note that not all of the configurations described below are necessarily essential configurations of the present invention.

[0010] 1. Transcription recording method The transfer recording method according to this embodiment includes a first layer forming step of discharging an image forming ink from an inkjet head onto a transfer medium having a release layer to form a first layer, a second layer forming step of discharging an adhesive ink from an inkjet head to form a second layer so as to overlap the first layer, and a thermal transfer step of thermally transferring the first layer and the second layer onto the fabric by heating the surface of the transfer medium on which the first and second layers have been formed while facing the fabric. Fig. 1 is a schematic diagram showing the outline of the steps of the transfer recording method according to this embodiment.

[0011] 1.1.First layer formation process In the first layer forming step, an image forming ink is discharged from an inkjet head onto a transfer medium having a release layer to form a first layer.

[0012] 1.1.1.Transfer medium The transfer medium 1 is not limited as long as it has a release layer 12. In the illustrated example, it has a base material 11 and a release layer 12. The shape of the transfer medium 1 is not particularly limited, but a sheet-like one is preferably used. This allows the first layer 2 and the second layer 3 to be more suitably formed by the inkjet method. When the base material 11 is in the form of a sheet, the thickness of the base material 11 is, for example, 25 μm or more and 300 μm or less, and preferably 50 μm or more and 200 μm or less.

[0014] The release layer 12 is a layer having releasability. By having the release layer 12 in the transfer medium 1, it is possible to suppress the constituent materials of the first layer 2 and the second layer 3 from remaining on the transfer medium 1 after the thermal transfer process. Examples of the constituent material of the release layer 12 include a polyethylene wax-based release agent, a silicone-based release agent, and a fluorine-based release agent. The thickness of the release layer 12 is not particularly limited, but is preferably 5 μm or more and 80 μm or less, and more preferably 10 μm or more and 50 μm or less.

[0024] The image forming ink 2' may contain a self-dispersing pigment as a pigment. The self-dispersing pigment is a self-dispersing pigment having a hydrophilic group on its pigment surface, and examples of the hydrophilic group include -OM, -COOM, -CO-, -SO3M, -SO2M, -SON2NH2, -RSO2M, -PO3HM, -PO3M2, -SON2NHCOR, -NH3, and -NR3. In the formula, M represents a hydrogen atom, an alkali metal, ammonium, or an organic ammonium, and R represents an alkyl group having 1 to 12 carbon atoms or a naphthyl group which may have a substituent. In addition, for example, a phenyl group may be present between the pigment surface and the hydrophilic group.

[0025] The self-dispersing pigment can be produced, for example, by subjecting the pigment to a physical or chemical treatment to bond a hydrophilic group to the surface of the pigment. An example of such a physical treatment is vacuum plasma treatment. An example of a chemical treatment is wet oxidation in which the pigment is oxidized with an oxidizing agent in water.

[0026] In addition, as the self-dispersing pigment, for example, a self-dispersing pigment that has been surface-treated by oxidation treatment with hypohalous acid and / or hypohalite, oxidation treatment with ozone, or oxidation treatment with persulfuric acid and / or persulfate is preferable in terms of high color development. In addition, as the self-dispersing pigment, a commercially available product can also be used, and preferred examples include Microjet CW1 (manufactured by Orient Chemical Industry Co., Ltd.), CAB-O-JET250C, CAB-O-JET260M, CAB-O-JET270Y, CAB-O-JET444MP (all manufactured by Cabot Corporation), etc.

[0027] The pigment content in the image forming ink 2' is not particularly limited, but is preferably 1.0% by mass or more and 25.0% by mass or less, more preferably 2.0% by mass or more and 20.0% by mass or less, and even more preferably 5.0% by mass or more and 15.0% by mass or less.

[0028] This makes it easier to ensure sufficient color density in the recording area 4 formed using the image-forming ink 2', and improves the color development on the woven fabric, while also improving the storage stability of the image-forming ink 2', the ejection stability by the inkjet method, and the clogging recovery properties of the inkjet head.

[0029] (2)Water The image-forming ink 2' contains water. Examples of water include pure water such as ion-exchanged water, ultrafiltered water, reverse osmosis water, and distilled water, as well as ultrapure water from which ionic impurities have been removed as much as possible. In addition, by using water sterilized by ultraviolet irradiation or the addition of hydrogen peroxide, the occurrence of bacteria and fungi can be reduced when the composition is stored for a long period of time.

[0030] Water functions as a dispersion medium for dispersing the pigment in the image forming ink 2'. The water content in the forming ink 2' is preferably 50.0% by mass or more and 75.0% by mass or less, more preferably 52.0% by mass or more and 70.0% by mass or less, and even more preferably 54.0% by mass or more and 65.0% by mass or less.

[0031] (3) Other ingredients (3-1) Organic solvent The image forming ink 2' may contain an organic solvent. This allows the viscosity and surface tension of the image forming ink 2' to be suitably adjusted. In addition, for example, the image forming ink 2' has excellent moisture retention, which more effectively prevents the solid content of the image forming ink 2' from unintentionally precipitating due to drying in an inkjet head or the like, and also provides better clogging recovery and better ejection stability of the image forming ink 2'.

[0032] As the organic solvent, a water-soluble organic solvent is preferably used, and as such a water-soluble organic solvent, an organic solvent having a solubility in water at 25° C. of 10 g / 100 g water or more can be suitably used.

[0033] The organic solvent contained in the image-forming ink 2', particularly the water-soluble organic solvent, may be, for example, a polyol compound, a glycol ether, a cyclic amide compound, etc., and one or more selected from these may be used in combination.

[0034] Specific examples of polyol compounds include 1,2-pentanediol, glycerin, ethylene glycol, diethylene glycol, triethylene glycol, polyethylene glycol, propylene glycol, dipropylene glycol, tripropylene glycol, polypropylene glycol, polyoxyethylene polyoxypropylene glycol, 1,2-hexanediol, 1,2-heptanediol, 1,3-propanediol, 1,2-butanediol, 1,3-butanediol, and 1,4-butanediol. Examples of glycols include diol, 2,3-butanediol, 2-methyl-3-phenoxy-1,2-propanediol, 3-(3-methylphenoxy)-1,2-propanediol, 3-hexyloxy-1,2-propanediol, 2-hydroxymethyl-2-phenoxymethyl-1,3-propanediol, 3-methyl-1,3-butanediol, 1,5-pentanediol, 1,6-hexanediol, 2-methyl-2,4-pentanediol, and 3-methyl-1,5-pentanediol.

[0035] Examples of the glycol ether include monoalkyl ethers of glycols selected from ethylene glycol, diethylene glycol, triethylene glycol, polyethylene glycol, propylene glycol, dipropylene glycol, tripropylene glycol, polypropylene glycol, and polyoxyethylene polyoxypropylene glycol. Examples of the monoalkyl ether include triethylene glycol monomethyl ether, triethylene glycol monobutyl ether, triethylene glycol monoethyl ether, and dipropylene glycol monopropyl ether.

[0036] Examples of cyclic amide compounds include 2-pyrrolidone, N-methyl-2-pyrrolidone, N-hydroxyethyl-2-pyrrolidone, 1,3-dimethylimidazolidinone, 2-piperidone (δ-valerolactam), and N-cyclohexyl-2-pyrrolidone.

[0037] The content of the organic solvent in the image forming ink 2' is preferably from 5.0 to 35.0% by mass, more preferably from 10.0 to 30.0% by mass, and even more preferably from 15.0 to 25.0% by mass.

[0038] This makes it possible to more suitably adjust the viscosity and surface tension of the image forming ink 2'. Also, the moisture retention of the image forming ink 2' is improved, which more effectively prevents the solid content of the image forming ink 2' from unintentionally precipitating due to drying in an inkjet head or the like, improves clogging recovery, and improves the ejection stability of the image forming ink 2'.

[0039] (3-2) Thermoplastic resin The image forming ink 2' may contain a thermoplastic resin. This can, for example, improve the adhesion of the recording portion 4 containing a pigment to the fabric 5. Also, the transferability due to the thermoplastic resin contained in the image forming ink can be exhibited. That is, in addition to the transferability of the adhesive ink described below, the transferability of the image can be improved. Also, the texture of the recorded matter 100 produced can be improved.

[0040] The content of thermoplastic resin in the image forming ink 2' may be 15.0 mass% or less, and the image forming ink 2' may not contain resin, but the content of thermoplastic resin in the image forming ink 2' is preferably 2.0 mass% or more and 13.0 mass% or less, more preferably 4.0 mass% or more and 12.0 mass% or less, and even more preferably 7.0 mass% or more and 11.0 mass% or less.

[0041] The form of the thermoplastic resin in the image forming ink 2' is not particularly limited. For example, the thermoplastic resin may be contained in the image forming ink 2' in a dispersed state or in a dissolved state, but is preferably contained in a dispersed state.

[0042] When the thermoplastic resin is contained in a dispersed state in the image forming ink 2', the average particle size is preferably 30 nm or more and 3 μm or less, more preferably 50 nm or more and 1 μm or less, and even more preferably 60 nm or more and 300 nm or less.

[0043] In this specification, the average particle size refers to the average particle size based on volume, and can be determined, for example, by adding a sample to methanol, dispersing the sample for 3 minutes using an ultrasonic disperser, and measuring the dispersion using a Coulter Counter particle size distribution measuring instrument (TA-II model manufactured by COULTER ELECTRONICS INS) with an aperture of 50 μm.

[0044] Examples of the thermoplastic resin contained in the image-forming ink 2' include polyurethane, polyester, styrene-acrylic resin, acrylic resin, polyvinyl chloride, etc., and one or more selected from these may be used in combination. Among these, polyurethane is preferred.

[0045] The glass transition temperature of the thermoplastic resin contained in the image forming ink 2′ is preferably −40° C. or higher and 0° C. or lower, more preferably −35° C. or higher and −5° C. or lower, and even more preferably −30° C. or higher and −10° C. or lower. This allows the texture, washing fastness, etc. of the produced recorded matter 100 to be made more excellent.

[0046] When the image-forming ink 2′ contains a thermoplastic resin, when the content of the thermoplastic resin in the image-forming ink 2′ is XR [mass %] and the content of the colorant in the image-forming ink 2′ is XP [mass %], it is preferable that the relationship satisfies 0.2≦XR / XP≦1.8, it is more preferable that the relationship satisfies 0.6≦XR / XP≦1.5, and it is even more preferable that the relationship satisfies 0.8≦XR / XP≦1.2.

[0047] This makes it easier to ensure sufficient color density in the recording section 4 formed using the image forming ink 2', and makes it possible to improve the color development on the fabric. The storage stability of the image forming ink 2', the ejection stability by the inkjet method, and the clogging recovery property of the inkjet head can be improved. In addition, the texture of the recorded matter 100 and the adhesion of the recorded part 4 to the fabric 5 can be improved.

[0048] (3-3) Surfactants The image forming ink 2′ may contain a surfactant. As the surfactant, for example, various surfactants such as anionic surfactants, cationic surfactants, and nonionic surfactants can be used.

[0049] When the image-forming ink 2' contains a surfactant, the content of the surfactant in the image-forming ink 2' is preferably 0.02% by mass or more and 1.50% by mass or less, more preferably 0.05% by mass or more and 1.00% by mass or less, and even more preferably 0.10% by mass or more and 0.70% by mass or less.

[0050] (3-4) Other ingredients The image forming ink 2' may contain components other than those described above. Hereinafter, in this section, such components are also referred to as "other components".

[0051] Other components include, for example, chelating agents, preservatives, mildew inhibitors, rust inhibitors, flame retardants, various dispersants, pH adjusters such as triethanolamine, dyes, antioxidants, ultraviolet absorbers, oxygen absorbers, dissolution aids, and penetrating agents.

[0052] Examples of the chelating agent include ethylenediaminetetraacetate. Examples of the preservatives and antifungal agents include sodium benzoate, sodium pentachlorophenol, sodium 2-pyridinethiol-1-oxide, sodium sorbate, sodium dehydroacetate, 1,2-dibenzisothiazolin-3-one, and 4-chloro-3-methylphenol. Examples of the rust inhibitors include benzotriazole. Examples of the preservatives and antifungal agents that can be used include compounds having an isothiazolin ring structure in the molecule.

[0053] The content of other components in the image-forming ink 2' is preferably 6.0% by mass or less, and more preferably 5.0% by mass or less.

[0054] (4) Physical properties, etc. The viscosity of the image forming ink 2' at 25°C is preferably 2 mPa·s to 10 mPa·s, more preferably 3 mPa·s to 8 mPa·s. This makes it more difficult for the nozzles of the inkjet head to become clogged, and improves the ejection stability of the image forming ink 2'. It also makes it possible to improve the recovery of nozzles from clogging.

[0055] The viscosity can be determined by measurement using a vibration viscometer, a rotational viscometer, a capillary viscometer, or a falling ball viscometer. For example, the viscosity can be determined by measurement using a vibration viscometer in accordance with JIS Z8809.

[0056] The surface tension of the image-forming ink 2' at 25°C is not particularly limited, but is preferably from 20 mN / m to 60 mN / m, more preferably from 25 mN / m to 50 mN / m, and even more preferably from 27 mN / m to 40 mN / m.

[0057] This makes it more difficult for the nozzles of the inkjet head to become clogged, resulting in a higher image quality. This further improves the ejection stability of the forming ink 2', and also improves the ability to recover from clogging of the nozzles.

[0058] The surface tension may be measured by the Wilhelmy method or the Ring method using a surface tensiometer (e.g., DY-300, DY-500, DY-700, etc., manufactured by Kyowa Interface Science Co., Ltd.).

[0059] 1.1.3. Discharge by the Inkjet Method The first layer 2 is formed by ejecting an image-forming ink 2' by an inkjet method onto a transfer medium 1 having a release layer 12. More specifically, the image-forming ink 2' is ejected so as to adhere to the release layer 12 of the transfer medium 1.

[0060] Examples of the inkjet method include on-demand methods such as a charge deflection method, a continuous method, a piezoelectric method, and a bubble jet (registered trademark) method, and in particular, a piezoelectric method in which ink is discharged from an inkjet head using a piezoelectric vibrator is preferred. This can further reduce the denaturation of the components of the image forming ink 2' in the inkjet head 50, and can improve the discharge stability by the inkjet method.

[0061] Moreover, the inkjet head 50 may be a line head that performs printing by a line method, or a serial head that performs printing by a serial method.

[0062] In the line method using a line head, for example, an inkjet head having a width equal to or greater than the recording width of the transfer medium 1 is fixed to a recording device. Then, the transfer medium 1 is moved along the sub-scanning direction (the transport direction of the transfer medium 1), and ink droplets are ejected from the nozzles of the inkjet head 50 in conjunction with this movement, thereby forming a first layer 2 on the transfer medium 1.

[0063] In the serial method using a serial head, for example, an inkjet head 50 is mounted on a carriage that is movable in the width direction of the transfer medium 1. Then, the carriage is moved along the main scanning direction (width direction of the transfer medium 1), and ink droplets are ejected from nozzles of the serial head, which is the inkjet head 50, in conjunction with this movement, thereby forming a first layer 2 on the transfer medium 1.

[0064] In this step, the first layer 2 is formed as a reverse image of the recording portion 4 to be formed on the fabric 5. In addition, in this step, multiple types of image-forming inks 2' may be used. For example, multiple types of image-forming inks 2' having different color tones, more specifically, black ink, cyan ink, magenta ink, and yellow ink may be used.

[0065] For example, in the first layer forming step, a first image forming ink containing a chromatic colorant and a second image forming ink containing a white pigment may be discharged in an overlapping manner to form the first layer. In this way, even when the first image forming ink (color ink) and the second image forming ink (white ink) are discharged in an overlapping manner, the total amount of ink attached increases, but even in such a case, bleeding of the image is suppressed, and a high-quality image can be formed.

[0066] 1.2.Second layer formation process In the second layer forming step, adhesive ink is ejected from an inkjet head to form the second layer so as to overlap the first layer.

[0067] 1.2.1.Adhesive ink The adhesive ink 3' is used to form the second layer 3, and contains a thermoplastic resin and water. (1)Thermoplastic resin By including a thermoplastic resin in the adhesive ink 3', the adhesiveness of the recording portion 4 to the fabric 5 can be improved, and the washing fastness of the recorded matter 100 produced can be improved.

[0068] The thermoplastic resin contained in the adhesive ink 3' is the same as that described in the section "1.1.2. Image forming ink (3-2) Thermoplastic resin", and therefore a description thereof will be omitted.

[0069] The thermoplastic resin contained in the adhesive ink 3' is preferably at least one selected from polyester resin, urethane resin, acrylic resin, and vinyl chloride resin, which allows for better image transfer.

[0070] The melting point of the thermoplastic resin contained in the adhesive ink 3′ is preferably from 80° C. to 140° C., more preferably from 85° C. to 130° C., and even more preferably from 90° C. to 120° C. This allows the texture and washing fastness of the recorded matter 100 to be compatible at a higher level.

[0071] The softening point of the thermoplastic resin is preferably equal to or lower than the heating temperature of the fabric in the thermal transfer process. The softening point of the thermoplastic resin is preferably 80° C. or higher and 170° C. or lower, more preferably 90° C. or higher and 160° C. or lower, and even more preferably 100° C. or higher and 150° C. or lower. When the softening point of the thermoplastic resin is within this range, the tackiness of the transferred product can be further suppressed, and damage to the fabric caused by heat during thermal transfer can be further reduced.

[0072] The softening point of a thermoplastic resin can be measured, for example, using a Mettler Toledo Dropping Point System DP70. The measurement is performed by heating the material until it changes from a solid to a liquid state, and the temperature at which the material flows a certain distance under the specified measurement conditions is measured. In the softening point measurement, a special sample cup with a 6.35 mm opening at the bottom is used, and the resin is weighed with a stainless steel ball of standardized dimensions to drop the softened resin from the cup during heating. The furnace temperature at which the resin softens and drops 19 mm from the cup orifice is recorded as the softening point temperature of the resin.

[0073] The solid content of the thermoplastic resin in the adhesive ink 3' is 5% by mass or more and 25% by mass or less with respect to the total amount of the adhesive ink 3'. The solid content of the thermoplastic resin in the adhesive ink 3' is preferably 5.0% by mass or more and 20.0% by mass or less, more preferably 6.0% by mass or more and 17.0% by mass or less, and even more preferably 7.0% by mass or more and 15.0% by mass or less. This allows the texture and washing fastness of the recorded matter 100 to be compatible at a higher level.

[0074] (2)Water The adhesive ink 3' contains water. The water is a component in the adhesive ink 3' that functions, for example, as a dispersion medium for dispersing the resin or a solvent for dissolving the resin. The water is the same as that described in the section "1.1.2. Image-forming ink (2) Water," and therefore a description thereof will be omitted.

[0075] The water content in the adhesive ink 3' is preferably 50.0% by mass or more and 85.0% by mass or less, more preferably 55.0% by mass or more and 80.0% by mass or less, and even more preferably 60.0% by mass or more and 75.0% by mass or less.

[0076] (3) Organic solvents, surfactants and other components The adhesive ink 3' contains at least one of an organic solvent, a surfactant, and other components. These components are the same as those described in the section "1.1.2. (3-1) Organic Solvent, (3-3) Surfactant, and (3-4) Other Components of the Image-Forming Ink," and therefore the description thereof will be omitted.

[0077] 1.2.2.Physical properties etc. The viscosity of the adhesive ink 3' at 25°C is preferably from 2 mPa·s to 10 mPa·s, and more preferably from 3 mPa·s to 8 mPa·s, which makes it more difficult for the nozzles of the inkjet head to become clogged, and improves the ejection stability of the adhesive ink 3'.

[0078] The surface tension of the adhesive ink 3' at 25°C is not particularly limited, but is preferably from 20 mN / m to 60 mN / m, more preferably from 25 mN / m to 50 mN / m, and even more preferably from 27 mN / m to 40 mN / m, which makes it more difficult for the nozzles of the inkjet head to become clogged, and improves the ejection stability of the adhesive ink 3'.

[0079] 1.2.3. Discharge by the Inkjet Method The second layer 3 is formed by discharging an adhesive ink 3′ by an inkjet method onto the transfer medium 1 on which the first layer 2 has been formed. That is, the second layer 3 is formed on the first layer 2.

[0080] The inkjet method is the same as that described in the section "1.1.3. Discharge by inkjet method", so a description thereof will be omitted. As the inkjet method, a piezoelectric type that discharges from an inkjet head using a piezoelectric vibrator is more preferable. This can further reduce the denaturation of the components of the adhesive ink 3' in the inkjet head 50', and can improve the discharge stability by the inkjet method.

[0081] Although it varies depending on the composition of the pigment ink 2', the time from when the pigment ink 2' is applied to the transfer medium 1 to when the adhesive ink 3' is applied is preferably at least 1 second and at most 60 seconds, and more preferably at least 2 seconds and at most 30 seconds.

[0082] In this step, multiple types of adhesive inks 3' may be used.

[0083] 1.3.Thermal transfer process In the thermal transfer process, the surface of the transfer medium on which the first and second layers are formed is heated while facing the fabric, thereby thermally transferring the first and second layers to the fabric.

[0084] 1.3.1.Fabric The fabric is not particularly limited. The material constituting the fabric is also not particularly limited, and examples thereof include natural fibers such as cotton, hemp, wool, and silk, synthetic fibers such as polypropylene, polyester, acetate, triacetate, polyamide, and polyurethane, and biodegradable fibers such as polylactic acid, and may be blended fibers thereof. The fabric may be any of the above-mentioned fibers in the form of woven fabric, knitted fabric, nonwoven fabric, etc., or may be blended.

[0085] In this embodiment, examples of the form of the fabric include cloth, clothing, and other accessories. Fabrics include woven fabrics, knitted fabrics, nonwoven fabrics, and the like. Clothing and other accessories include sewn T-shirts, handkerchiefs, scarves, towels, carrier bags, cloth bags, curtains, sheets, bed covers, wallpaper, and other furniture, as well as fabrics before and after cutting as parts before sewing. Examples of the form of these include long rolls, cut to a predetermined size, and product shapes.

[0086] 1.3.2. Heating conditions The heating temperature in this step is not particularly limited, but is preferably from 120°C to 270°C, more preferably from 140°C to 250°C, and even more preferably from 150°C to 210°C.

[0087] This makes it possible to suppress the constituent materials of the first layer 2 and the second layer 3 from remaining on the transfer medium 1, while at the same time making it possible to improve the productivity of the recorded matter 100 with reduced energy consumption.

[0088] When the glass transition temperature of the thermoplastic resin contained in the adhesive ink 3' is Tg [°C] and the heating temperature in the thermal transfer process is Tp [°C], it is preferable to satisfy the relationship of 70≦Tp-Tg≦290, more preferably the relationship of 95≦Tp-Tg≦260, and even more preferably the relationship of 110≦Tp-Tg≦210. This reduces the amount of constituent materials of the first layer 2 and the second layer 3 remaining on the transfer medium 1, and the productivity of the recorded matter 100 can be improved with energy savings.

[0089] The heating time in this step is not particularly limited, but is preferably from 5 to 90 seconds, more preferably from 15 to 70 seconds, and even more preferably from 20 to 60 seconds.

[0090] This process may be carried out by any method, provided that the surface of the transfer medium 1 on which the first layer 2 and the second layer 3 are formed is heated while facing the fabric 5, but is more preferably carried out by heat pressing.

[0091] When this step is carried out by heat pressing, the pressure applied to the laminate of the transfer medium 1 and the fabric 5 is 0.1 N / cm 2 More than 30N / cm 2 Less than 0.6N / cm is preferable. 2 More than 15N / cm 2 Less than 1.5N / cm is more preferable. 2 More than 5N / cm 2 The following is even more preferred:

[0092] 1.4. Recordings Through the above-mentioned steps, a recorded matter 100 is obtained (1d). The recorded matter 100 obtained as described above has a recorded portion 4 formed by a first layer 2 and a second layer 3.

[0093] At least a part of the recording part 4 may penetrate into the absorbent fabric 5. Usually, at least a part of the recording part 4 is formed by integrating the constituent material of the first layer 2 with the constituent material of the second layer 3, but in the illustrated configuration, the recording part 4 is entirely formed by integrating the constituent material of the first layer 2 with the constituent material of the second layer 3.

[0094] 1.5. Coating amount and other In the transfer recording method of this embodiment, the coating amount of the adhesive ink in the second layer forming process is 38 g / m 2 In the transfer recording method of the present embodiment, the total amount of application of the image forming ink in the first layer forming process and the adhesive ink in the second layer forming process is 212 g / m2 In this way, bleeding of the image is suppressed without adjusting the evaporation rate of the ink liquid components, and a high-quality image can be formed on the fabric. When a plurality of image forming inks are applied in the first layer forming step, the total amount of the applied inks and the amount of the adhesive ink applied in the second layer forming step must be less than 212 g / m. 2 The following is the result.

[0095] The amount of adhesive ink applied in the second layer formation process is 47 g / m 2 More preferably, 57 g / m 2 The upper limit of the amount of adhesive ink applied in the second layer forming step is not particularly limited, but is preferably 150 g / m 2 Less than 140 g / m 2 Less than 100 g / m is more preferable. 2 The following is more preferable. By doing so, the ink liquid Even without adjusting the evaporation rate of the components, bleeding of the image is further suppressed, and a higher quality image can be formed on the fabric.

[0096] On the other hand, the total amount of the image forming ink applied in the first layer forming process and the adhesive ink applied in the second layer forming process was 210 g / m 2 More preferably, it is 200 g / m or less. 2 More preferably, it is 180 g / m or less. 2 By doing so, bleeding of the image can be further suppressed without adjusting the evaporation rate of the ink liquid components, and a higher quality image can be formed on the fabric.

[0097] In the transfer recording method of the present embodiment, when the image forming ink further contains a thermoplastic resin, the total amount of the image forming ink applied in the first layer forming step and the adhesive ink applied in the second layer forming step is 76 g / m 2It is more preferable that the total amount of the applied image forming ink in the first layer forming step and the applied amount of the adhesive ink in the second layer forming step is 90 g / m or more. In this case, the transferability of the image can be further improved by the resin contained in the image forming ink. 2 More preferably, it is 110 g / m or more. 2 More preferably, it is 130 g / m or more. 2 More preferably, it is equal to or greater than this.

[0098] The amount of ink applied to an A4-sized transfer medium is converted to a duty of 19.24 g / m 2 corresponds to 100% duty.

[0099] In this way, according to the transfer recording method of the present embodiment, bleeding of the image is suppressed without adjusting the evaporation rate of the ink liquid component, and a high-quality image can be formed on the fabric, so that the recording resolution can be increased. For example, even if the recording resolution is 600 dpi x 600 dpi or more, preferably 720 dpi x 720 dpi or more, a high-quality image can be formed on the fabric. In other words, when the recording resolution is high, the effect of the transfer recording method of the present embodiment becomes more remarkable.
