Title: Ink Jet Ink Composition And Recording Method

Description:
The present application is based on, and claims priority from JP Application Serial Number 2021-181112, filed Nov. 5, 2021, the disclosure of which is hereby incorporated by reference herein in its entirety. 
     BACKGROUND 
     1. Technical Field 
     The present disclosure relates to an ink jet ink composition and a recording method. 
     2. Related Art 
     There has been known an ink jet recording method in which an image is recorded on a recording medium by ejecting fine ink droplets from nozzles of an ink jet head of an ink jet recording apparatus. In recent years, besides image recording performed on a recording medium, such as regular paper, having an excellent ink absorbency, the ink jet recording method has become to be used for image recording on a low-absorbing recording medium, such as art paper or coated paper, having a low ink absorbency or a non-absorbing recording medium, such as a plastic film, hardly absorbing an ink. In addition, even for image recording on the low-absorbing recording medium or the non-absorbing recording medium as described above, a water-based ink jet ink composition (hereinafter, referred to as “water-based ink” or “ink composition” in some cases) using water as a primary component has become to be used. 
     When the recording is performed on the low-absorbing recording medium or the non-absorbing recording medium as described above, and in particular, is performed on a plastic film, the water-based ink is not likely to wet-spread on the recording medium, and as a result, an image quality (wet spreadability) is disadvantageously liable to be degraded such that a color development property of a recorded matter cannot be sufficiently obtained. 
     JP-A-2018-44074 has disclosed a water-based ink jet ink composition containing a glycol monoether solvent (3-methoxy-1-butanol). 
     When the specific solvent as described above is contained in the ink, since the solvent as described above has a high drying property, clogging is liable to occur in an ink jet head, and as a result, a clogging recovery property is inferior. In addition, the solvent described above has characteristics to degrade a dispersion stability of an ink component present in a dispersion form, and as a result, a storage stability of the ink is also inferior. 
     As described above, an ink jet ink composition excellent in image quality (wet spreadability), abrasion resistance, clogging recovery property, and storage stability could not be obtained in the past.

     DESCRIPTION OF EXEMPLARY EMBODIMENTS 
     Hereinafter, embodiments of the present disclosure will be described. The following embodiments are described to explain examples of the present disclosure. The present disclosure is not at all limited to the following embodiments and includes various types of changed and/or modified embodiments to be performed without departing from the scope of the present disclosure. In addition, all the structures described below are not always required to be essential structures. 
     1. Ink Jet Ink Composition 
     An ink jet ink composition according to one embodiment of the present disclosure is a water-based ink jet ink composition which includes a colorant, an amine, and a water-soluble low molecular weight organic compound and which is used for recording on a non-absorbing recording medium or a low-absorbing recording medium. The water-soluble low molecular weight organic compound contains an alkylene glycol monoether (B) represented by general formula (1) having a standard boiling point of 210° C. or less and an alkanediol (A) having a standard boiling point of 210° C. or less at a mass ratio (B/A) of 0.2 to 0.9, a content of a water-soluble low molecular weight organic compound having a standard boiling point of 250° C. or less is 8 to 30 percent by mass with respect to a total mass of the ink composition, a water-soluble low molecular weight organic compound which is an alkane polyol having a standard boiling point of more than 250° C. is not contained at a content of more than 3 percent by mass with respect to the total mass of the ink composition, and a content of the amine with respect to the total mass of the ink composition is 5 percent by mass or less. 
     
       
         
         
             
             
         
       
     
     In the general formula (1), R 1  represents an alkylene group having 2 to 5 carbon atoms, R 2  represents an alkyl group having 1 or 2 carbon atoms, and n represents 1 or 2. 
     When the recording is performed on the low-absorbing recording medium or the non-absorbing recording medium, and in particular, is performed on a plastic film, a water-based ink is not likely to wet-spread on the recording medium, and as a result, an image quality (wet spreadability) is disadvantageously liable to be degraded such that a color development property of a recorded matter cannot be sufficiently obtained. 
     In recent days, it was found that when a specific alkylene glycol monoether is contained in a water-based ink, the wet spreadability thereof on a low-absorbing recording medium or a non-absorbing recording medium can be improved. 
     However, since the specific alkylene glycol monoether as described above has a high drying property, clogging is liable to occur in an ink jet head, and hence, a clogging recovery property is inferior. In addition, the specific alkylene glycol monoether has characteristics to degrade a dispersion stability of an ink component, such as a colorant, present in a dispersion form, and hence, a storage stability of the ink is also inferior. 
     On the other hand, in order to secure the clogging recovery property, when the ink composition is prepared so as to have an unnecessarily low drying property, the drying property thereof is degraded, and an abrasion resistance of the recorded matter is degraded. As a result, it was difficult to prepare a composition which secures the drying property and the abrasion resistance with good balance. 
     For example, when the clogging recovery property is tried to be secured using an organic solvent having a low drying property (that is, an organic solvent having a high moisture retaining property) in combination, the abrasion resistance tends to be degraded, and hence, those two types of properties are difficult to obtain with good balance. 
     In addition, when a total content of the organic solvents is unnecessarily increased, in general, the drying property is liable to be inferior, and the abrasion resistance is also liable to be degraded. Hence, the total content of the organic solvents in the ink is required to be set in a predetermined range or lower than that. By the ink composition in which the total content of the organic solvents is required to be set in a predetermined range or lower than that as described above, in the past, the clogging recovery property and the abrasion resistance were difficult to obtain at the same time. 
     In addition, since some high boiling point solvents, such as glycerin, are superior in moisture retaining property but inferior in drying property, the use thereof is preferably avoided. 
     In addition, as a compound which is excellent in clogging recovery property and moisture retaining property and which is also relatively excellent in abrasion resistance since the drying property is not likely to be degraded, a specific alkanediol, such as propylene glycol, may be mentioned. In addition, since the specific alkanediol is also not likely to degrade the dispersion stability of the ink component, such as the colorant, present in a dispersion form, the storage stability of the ink is also made excellent. 
     The specific alkanediol as described above was contained together with the specific alkylene glycol monoether described above at a specific ratio, and research to obtain the storage stability and the like was performed. However, the clogging recovery property and the abrasion resistance still could not be obtained at the same time. 
     Accordingly, through intensive research carried out by the present inventor, it was found that when an amine is also used in combination, excellent abrasion resistance and clogging recovery property can be obtained at the same time. The amine is superior in moisture retaining property, and even by the use of a small amount of the amine, the clogging recovery property can be made excellent. In addition, the degradation in drying property is relatively not likely to occur. Although the reason for this is not clearly understood, it is believed that since the amine is likely to be evaporated by secondary drying performed to complete the drying of the recorded matter, the abrasion resistance is also made excellent. 
     As described above, according to the ink jet ink composition of this embodiment, since the specific alkylene glycol monoether, the specific alkanediol, and the amine are used in combination, while an excellent image quality (wet spreadability) is obtained, excellent abrasion resistance, clogging recovery property, and storage stability can be obtained. 
     Hereinafter, individual components contained in the ink jet ink composition according to this embodiment will be described. 
     1.1. Colorant

Vat Blue 4 or 60 may be mentioned, and for example, one selected from the group consisting of C.I. Pigment Blue 15:3, 15:4, and 60 or a mixture containing at least two types thereof may be preferably mentioned.

Pigment Yellow 74, 109, 110, 128, 138, 150, and 180 or a mixture containing at least two types thereof may be preferably mentioned. 
     At least one pigment other than those mentioned above may also be used. For example, an orange pigment and/or a green pigment may be mentioned. 
     The pigments mentioned above by way of example are examples of preferable pigments, and the present disclosure is not limited thereto. One of those pigments may be used alone, or at least two types thereof may be used as a mixture, and those pigments each may be used with a dye in combination. 
     In addition, the pigment may be used after being dispersed using a dispersant selected from a water-soluble resin, a surfactant, and the like or may be used after being dispersed as a self-dispersible pigment by oxidizing or sulfonizing a pigment surface using ozone, hypochlorous acid, fuming sulfuric acid, or the like. In addition, as the surfactant which may be used as the dispersant, a surfactant which may be contained in the ink composition described below may also be used.

     The water-soluble resin which may be used as the dispersant can be obtained using a known polymer preparation method. 
     In addition, the pigment may be dispersed as a resin-coated pigment which is coated with a resin. The resin-coated pigment is dispersible in a water-based medium in the form of a pigment coated or enclosed with a high molecular weight compound, and a pigment dispersion liquid has a water phase in which the resin-coated pigment is dispersed. 
     The resin-coated pigment is formed by a known physical/mechanical method or chemical method. In particular, for example, a phase separation method (coacervation), a liquid drying method (interface precipitation method), a spray drying method, a pan coating method, a liquid curing coating method, an interface polymerization method, an in-situ method, or an ultrasonic method may be used without any particular restriction. 
     For example, when a monomer of the water-soluble resin is polymerized by emulsion polymerization or the like under the presence of the pigment, the resin-coated pigment can be obtained. 
     In addition, as a preferable manufacturing method of the resin-coated pigment, a phase inversion emulsification method may be mentioned.

As a mixing method of each component, a method in which materials are sequentially added to a container equipped with a stirring device, such as a mechanical stirrer or a magnetic stirrer, and are then stirred and mixed together may be preferably used. As a filtration method, for example, centrifugal filtration or filter filtration may be performed, if needed. 
     1.9. Physical Properties 
     In consideration of the balance between the image quality and the reliability as an ink jet recording ink, the ink jet ink composition according to this embodiment has a surface tension at 20° C. of preferably 18 to 40 mN/m, more preferably 20 to 35 mN/m, and further preferably 22 to 33 mN/m. Measurement of the surface tension may be performed such that by using an automatic surface tensiometer CBVP-Z (trade name, manufactured by Kyowa Interface Science Co., Ltd.), a surface tension at which a platinum plate is wetted with the ink in an environment at 20° C. is confirmed. 
     In addition, from the consideration similar to that described above, a viscosity of the ink jet ink composition according to this embodiment at 20° C. is preferably 3 to 10 mPa·s and more preferably 3 to 8 mPa·s. In addition, measurement of the viscosity may be performed such that by using an viscoelastic tester MCR-300 (trade name, manufactured by Pysica) or the like, a viscosity in an environment at 20° C. is measured. 
     1.10. Application 
     The ink jet ink composition according to this embodiment is used for recording on a non-absorbing recording medium or a low-absorbing recording medium. In addition, as a recording mode, a recording method which will be described later may be used. 
     The non-absorbing recording medium or the low-absorbing recording medium indicates a recording medium absorbing no liquid, such as an ink, or a recording medium absorbing almost no liquid, respectively. From a quantitative point of view, the non-absorbing recording medium or the low-absorbing recording medium indicates a recording medium having a water absorbing amount of 10 mL/m2 or less from a contact start to a point of 30 msec 1/2  by Bristow method. This Bristow method is a most popular measurement method of a liquid absorption amount in a short time and has also been employed by Japan Technical Association of the Pulp and Paper Industry (JAPAN TAPPI). 
     The details of the test method have been disclosed in Standard No. 51 “Paper and Paperboard-Liquid Absorption Test Method-Bristow Method”, JAPAN TAPPI PAPER AND PULP TEST METHODS, 2000. On the other hand, an absorbing recording medium indicates a recording medium corresponding to neither the non-absorbing recording medium nor the low-absorbing recording medium. 
     As the non-absorbing recording medium, there may be mentioned a medium in which a recording surface contains a plastic and more preferably, a medium in which a recording surface is formed of a plastic. In this case, on the recording surface, neither an absorbing layer to absorb a liquid nor a receiving layer is provided. For example, there may be mentioned a medium in which a plastic is coated on a substrate, such as paper, a medium in which a plastic film is adhered to a substrate, such as paper, or a medium formed from a plastic film having neither an absorbing layer nor a receiving layer. As the plastic described above, for example, there may be mentioned a poly(vinyl chloride), a polyethylene terephthalate), a polycarbonate, a polystyrene, a polyurethane, a polyethylene, or a polypropylene. 
     In addition, as the low-absorbing recording medium, a recording medium called a coated paper having a surface on which a coating layer is provided may be mentioned. For example, as a low-absorbing recording medium using paper as the substrate, printing paper, such as art paper, coated paper, or mat paper, may be mentioned, and as a low-absorbing recording medium using a plastic film as the substrate, a recording medium in which, for example, a hydrophilic polymer is applied on a surface formed, for example, from a poly(vinyl chloride), a polyethylene terephthalate), a polycarbonate, a polystyrene, a polyurethane, a polyethylene, or a polypropylene or a recording medium in which particles formed of silica, titanium, or the like are applied together with a binder on the surface as described above may be mentioned. 
     The ink jet ink composition according to this embodiment may be also preferably used for recording on a soft packaging film. The soft packaging film is one type of the non-absorbing recording medium described above. In more particular, the soft packaging film is a film material having a high flexibility to be used, for example, for food packaging and/or packaging of toiletries and cosmetic articles and is a film material which has a film thickness in a range of 5 to 70 μm and preferably 10 to 50 μm and which has a film surface on which a material having an antifogging property and/or antistatic property, an antioxidant, and/or the like is present. When an ink composition is adhered to this film, compared to a plastic film having an ordinary thickness, since the ink composition is more unlikely to be fixed, the abrasion resistance and the image quality (wet spreadability) may be inferior in some cases. However, even when the soft packaging film is used, by the ink jet ink composition according to this embodiment, excellent abrasion resistance and image quality (wet spreadability) tend to be obtained. 
     As a material forming a recording surface of the soft packaging film, for example, a material containing at least one resin selected from an olefin-based resin, such as a polyethylene or a polypropylene, an ester-based resin, such as a polyester, a vinyl chloride-based resin, such as a poly(vinyl chloride), and an amide-based resin, such as a polyamide, may be used. As a film substrate including the recording surface of the soft packaging film, a film or a sheet obtained by processing at least one of the resins mentioned above may be used. In the case of the film or the sheet formed from the resin, for example, either a non-stretched film or a stretched film stretched in one axial direction or two axial directions may be used, and a film or a sheet stretched in two axial directions is preferably used. In addition, if needed, films or sheets formed from at least one of those various types of resins mentioned above may also be used together after being adhered to each other in a laminated state. 
     In addition, the ink jet ink composition according to this embodiment may be also preferably used for recording on a sign graphic recording medium. As the sign graphic recording medium, although various types of materials, such as a banner, coated paper, mat paper, wallpaper, a cloth, and a plastic film, such as a PET or a PVC, may be mentioned, in particular, the ink jet ink composition described above is preferably applied to a transparent/translucent plastic film to be used for window display, car lapping, and the like. Many of those films each have a structure in which the substrate is formed, for example, form a flexible polyolefin, PET, or PVC, and an adhesive layer is provide on a surface opposite to the recording surface, and after the printing is performed, those films are each adhered to a window glass, a car body, or the like with this adhesive layer. When an ink is adhered to this film, since the ink is more unlikely to be fixed, the abrasion resistance and the image quality (wet spreadability) tend to be degraded in some cases. However, even when the sign graphic recording medium is used, by the ink jet ink composition according to this embodiment, excellent abrasion resistance and image quality (wet spreadability) tend to be obtained. 
     As a material forming the recording surface of the sign graphic film, a material containing at least one resin selected from an olefin-based resin, such as a polyethylene or a polypropylene, an ester-based resin, such as a polyester, a vinyl chloride-based resin, such as a poly(vinyl chloride), and an amide-based resin, such as a polyamide, may be used. 
     In addition, the recording medium may be colorless transparent, translucent, colored transparent, chromatic opaque, colorless opaque, or the like. 
     2. Recording Method 
     A recording method according to one embodiment of the present disclosure includes an adhesion step of adhering the ink jet ink composition described above to the non-absorbing recording medium or the low-absorbing recording medium by an ink jet method. 
     According to the recording method of this embodiment, the above ink jet ink composition which contains the specific alkylene glycol monoether, the specific alkanediol, and the amine in combination is used, and while an excellent image quality (wet spreadability) is obtained, excellent abrasion resistance, clogging recovery property, and storage stability are obtained. 
     2.1. Ink Adhesion Step 
     The recording method according to this embodiment includes an adhesion step (ink adhesion step) of adhering the ink jet ink composition described above to the non-absorbing recording medium or the low-absorbing recording medium by an ink jet method. 
     In addition, the ink jet method is a recording method in which from ejection nozzles of an ink jet head provided in a recording apparatus such as an ink jet printer, fine liquid droplets of an ink jet ink are ejected so as to be adhered to a recording medium or the like. 
     The ink adhesion step can be easily performed such that, for example, by using an ink jet recording apparatus  1  shown in  FIG.  1    which is one embodiment of an ink jet recording apparatus described below, an ink is ejected from an ink jet head  2 . In addition, a composition to be ejected from the ink jet head by an ink jet method and to be used for recording is called an ink jet ink composition. 
     An adhesion amount of the ink jet ink composition per unit area of a recording region of the recording medium is preferably 1 to 40 mg/inch 2 , more preferably 2 to 30 mg/inch 2 , even more preferably 4 to 20 mg/inch 2 , and further preferably 6 to 16 mg/inch 2 . In the recording, the maximum ink adhesion amount per unit area of the recording region of the recording medium is also preferably set in the range described above. 
     In addition, in the ink adhesion step of the recording method according to this embodiment, while the ink jet ink composition described above is ejected from the ink jet head, a main scanning in which a relative position between the recording medium and the ink jet head is transferred is preferably performed a plurality of times, and the number of main scannings performed on the same main scanning region is preferably 12 or less. An upper limit of the number of main scannings performed on the same main scanning region is more preferably 11 or less, even more preferably 10 or less, and further more preferably 9 or less. Although a lower limit of the number of main scannings is 1 or more and is not particularly limited, the lower limit described above is preferably 2 or more and more preferably 3 or more. 
     In the main scanning, a time of one main scanning is preferably 0.5 to 5 seconds, more preferably 1 to 4 seconds, and further preferably 2 to 3 seconds. The time of one main scanning (also called “main scanning time” in some cases) is a time required in one main scanning, to transfer a head location from a position facing one end of the recording medium to a position facing the other end thereof. 
     The ink adhesion step may be performed on a recording medium having a surface temperature of 45° C. or less when the ink jet ink composition described above is adhered thereto. That is, the ink adhesion step may be performed either with or without heating the recording medium. Even when the heating is performed, the recording medium is preferably heated so as to have a surface temperature of 45° C. or less. 
     An upper limit of the surface temperature of the recording medium is more preferably 42° C. or less, even more preferably 38° C. or less, and further preferably 32° C. or less, and particularly preferably 28° C. or less. A lower limit of the surface temperature thereof is preferably 20° C. or more, more preferably 23° C. or more, and further preferably 25° C. or more. 
     2.2. Treatment Liquid Adhesion Step 
     The recording method according to this embodiment may further include a step (treatment liquid adhesion step) of adhering a treatment liquid containing an aggregating agent to the non-absorbing recording medium or the low-absorbing recording medium. 
     As a method to adhere the treatment liquid to the recording medium, one of a non-contact method and a contact method, such as an ink jet method, a coating method, a method of applying the treatment liquid to the recording medium using various types of sprays, a method of applying the treatment liquid by immersing the recording medium therein, and a method of applying the treatment liquid to the recording medium by a brush or the like, may be used, or at least two of the methods described above may be used in combination. 
     The treatment liquid adhesion step may be performed such that for example, by the ink jet recording apparatus  1  as shown in  FIG.  1   , the treatment liquid may be ejected from the ink jet head  2 . Accordingly, the treatment liquid and the ink jet ink composition can be more preferably adhered to the recording medium by one ink jet recording apparatus. 
     The treatment liquid adhesion step may be performed either before or after the ink composition is adhered and may also be performed at the same time when the ink composition is adhered. 
     An adhesion amount of the treatment liquid per unit area of the recording region of the recording medium is preferably 0.1 to 5 mg/inch 2 , more preferably 0.3 to 4 mg/inch 2 , even more preferably 0.5 to 3 mg/inch 2 , and further preferably 0.7 to 1.5 mg/inch 2 . In the recording, the maximum adhesion amount of the treatment liquid per unit area of the recording region of the recording medium is also preferably set in the range described above. 
     Hereinafter, components contained in the treatment liquid will be described. 
     Treatment Liquid 
     The treatment liquid at least contains an aggregating agent, and as the aggregating agent, at least one selected from a polyvalent metal salt, an organic acid, and a cationic resin is contained at a content of 1 to 15 percent by mass with respect to a total mass of the treatment liquid. 
     When the treatment liquid adhesion step is performed using the treatment liquid as described above, the image quality (wet spreadability) tends to be made more excellent. In addition, even when the surface temperature of the recording medium in the ink adhesion step is relatively low, a preferable image quality (wet spreadability) is likely to be obtained. Hence, while a preferable image quality (wet spreadability) is secured, a thermal influence on the head is reduced, and the clogging recovery property can be made more preferable in some cases. 
     Aggregating Agent 
     The treatment liquid which may be used for the recording method according to this embodiment is a treatment liquid containing an aggregating agent. Since acting on the dispersibility of the component, such as the colorant (in particular, the pigment), contained in the ink jet ink composition, the aggregating agent has an action to aggregate a dispersion, such as the colorant. A degree of the aggregation of the dispersion by the aggregating agent is changed dependent on the types of the aggregating agents and objects to be aggregated and can be adjusted. By the aggregating action as described above, for example, a color development property of the image can be enhanced, and/or a fixing property of the image can be enhanced. 
     Although the aggregating agent is not particularly limited, for example, a metal salt, an acid, or a cationic compound may be mentioned, and as the cationic compound, for example, a cationic resin (cationic polymer) or a cationic surfactant may be used. Among those mentioned above, as the metal salt, a polyvalent metal salt is preferable, and as the cationic compound, a cationic resin is preferable.

     In addition, it should be noted that the treatment liquid described above can be prepared independently of the components contained in the ink jet ink composition described above and the contents thereof. 
     2.3. Primary Drying Step 
     In addition, the recording method according to this embodiment may further include a primary drying step. Since the step as described above is included, at an early stage in which the ink jet ink composition is adhered to the recording medium, the drying property of the ink can be improved, and an excellent image quality is likely to be obtained. 
     The primary drying step is a step to dry the ink at an early stage in which the ink jet ink composition is adhered to the recording medium. The primary drying step is a drying step to dry at least part of a solvent component of the ink so that the fluidity of the ink adhered to the recording medium is at least decreased. 
     As a method of the primary drying step, for example, there may be mentioned a method to perform ventilation at ordinary temperature (ordinary temperature wind) or ventilation with heating (hot wind) to a recording medium by a fan or the like; a radiation method using an IR heater or microwaves; a method to heat a recording medium by a platen heater or the like; and a method to be performed in combination of the methods described above. In addition, in the primary drying step according to this embodiment, the method described above is not particularly limited as long as being capable of improving the drying property of the ink, and it should be noted that heating is not always required. Hence, in the primary drying step of this embodiment, the method to perform ventilation at ordinary temperature may be used alone. In addition, the primary drying step is more preferably performed by a method to be performed with heating. 
     When the ventilation is performed as the primary drying step, a ventilation wind speed is preferably 0.5 to 10 m/s, more preferably 1 to 5 m/s, and further preferably 2 to 3 m/s. The wind speed is a wind speed in the vicinity of the surface of the recording medium. When the wind speed is in the range described above or higher than that, for example, the image quality is preferably made more excellent, and dew condensation on the head is preferably further suppressed. When the wind speed is in the range described above or lower than that, for example, the clogging recovery property is preferably made more excellent. A ventilation wind temperature is preferably 50° C. or less, preferably 10° C. or more, even more preferably 15° C. to 45° C., and further preferably 20° C. to 49° C. The ventilation wind temperature may also be ordinary temperature. 
     When the primary drying step is performed with heating, the primary drying step may be performed such that the ink is adhered to a heated recording medium or the heating is performed at an early stage after the ink is adhered to the recording medium. In the primary drying step, the heating is preferably started within 0.5 seconds at the latest after ink droplets are landed on the recording medium. 
     When the primary drying step is performed with heating, the heating may be performed before the ink adhesion step, at the same time as that of the ink adhesion, or at an early stage after the ink adhesion step and is preferably performed at the same time as that of the ink adhesion. By the heating order as described above, the ink adhesion step can be performed. 
     In addition, when the primary drying step is performed with heating, the heating in this step may be preferably performed in the temperature range described as the surface temperature of the recording medium in the above ink adhesion step. In addition, when the ink is adhered to the heated recording medium, the heating temperature in the primary drying step is the surface temperature of the recording medium when the ink is adhered thereto, and when the heating is performed at an early stage after the ink adhesion, the heating temperature in the primary drying step is the surface temperature of the recording medium when the heating is performed. In addition, the surface temperature described above is the maximum temperature during the heating in the primary drying step. 
     2.4. Post-Heating Step 
     The recording method according to this embodiment may further include a post-heating step of heating the recording medium to which the above ink jet ink composition is adhered so that a recording medium surface has a temperature of 60° C. to 120° C. and preferably 80° C. to 110° C. after passing through the platen. Accordingly, the drying property is further improved, and a recorded matter more excellent in abrasion resistance preferably tends to be obtained. 
     The post-heating step is a step to complete the recording and to sufficiently dry the recorded matter so as to be ready for use. The post-drying step is a drying step to sufficiently dry the solvent component of the ink and to form a film from a coating film of the ink by heating the resin or the like to be contained therein. 
     After a certain point of the recording medium to which the ink is adhered in the above ink adhesion step passes through the platen, the post-heating step is preferably started on the surface of the recording medium including the certain point described above. For example, in the ink jet recording apparatus  1  shown in  FIGS.  1  and  2   , after the ink is adhered to a certain point of a recording medium M by the ink jet head  2  facing a platen  11 , and the certain point of the recording medium M to which the ink is adhered passes through the platen  11 , the post-heating step is started by a heating heater  5  on the surface of the recording medium M including the certain point described above. 
     In addition, for example, when the ink jet recording apparatus is used, the heating of the recording medium in the post-heating step may be performed using an appropriate heating device. In addition, besides the heating device equipped in the ink jet recording apparatus, the heating may also be performed by an appropriate heating device. 
     In the post-heating step, a lower limit of the surface temperature of the recording medium is preferably 50° C. or more, more preferably 60° C. or more, even more preferably 70° C. or more, and further preferably 75° C. or more. An upper limit of the surface temperature of the recording medium is preferably 120° C. or less, more preferably 110° C. or less, even more preferably 100° C. or less, and further preferably 90° C. or less. 
     In addition, a preferable temperature in the primary drying step and a preferable temperature in the post-heating step are preferably different from each other. 
     2.5. Ink Jet Recording Apparatus 
     One example of an ink jet recording apparatus which can be used for the recording method according to this embodiment will be described with reference to the drawings. 
       FIG.  1    is a cross-sectional view schematically showing the ink jet recording apparatus  1 .  FIG.  2    is a perspective view showing one example of the structure of a carriage and its vicinity of the ink jet recording apparatus  1  shown in  FIG.  1   . As shown in  FIGS.  1  and  2   , the ink jet recording apparatus  1  includes the ink jet head  2 , an IR heater  3 , a platen heater  4 , the heating heater  5 , a cooling fan  6 , a pre-heater  7 , a ventilation fan  8 , a carriage  9 , the platen  11 , a carriage transfer mechanism  13 , a transport device  14 , and a control portion CONT. In the ink jet recording apparatus  1 , all operations thereof are controlled by the control portion CONT shown in  FIG.  2   . 
     The ink jet head  2  has a structure to perform recording on the recording medium M by ejecting a treatment liquid and an ink jet ink composition from nozzles of the ink jet head  2  so as to be adhered thereto. In this embodiment, the ink jet head  2  is a serial type ink jet head and is configured to adhere the ink to the recording medium M by a plurality of scannings performed in a main scanning direction relative to the recording medium M. The ink jet head  2  is mounted on the carriage  9  shown in  FIG.  2   . The ink jet head  2  is scanned a plurality of times in the main scanning direction relative to the recording medium M by the operation of the carriage transfer mechanism  13  to transfer the carriage  9  in a medium width direction of the recording medium M. The medium width direction is the main scanning direction of the ink jet head  2 . The scanning in the main scanning direction is also called a main scanning. 
     In addition, the main scanning direction is a direction in which the carriage  9  mounting the ink jet head  2  is transferred. In  FIG.  1   , the main scanning direction is a direction intersecting a sub-scanning direction which is a transport direction of the recording medium M shown by an arrow SS. In  FIG.  2   , the width direction of the recording medium M, that is, a direction represented by S 1 -S 2 , is a main scanning direction MS, and a direction represented by T 1 →T 2  is a sub-scanning direction SS. In addition, by one scanning, the scanning is performed in the main scanning direction, that is, in one direction represented by an arrow S 1  or an arrow S 2 . In addition, since the main scanning of the ink jet head  2  and the sub-scanning which is the transport of the recording medium M are repeatedly performed at least two times, the ink is recorded on the recording medium M. That is, the treatment liquid adhesion step and the ink adhesion step are performed by a plurality of main scannings in each of which the ink jet head  2  is transferred in the main scanning direction and by a plurality of sub-scannings in each of which the recording medium M is transported in the sub-scanning direction intersecting the main scanning direction. 
     The cartridge  12  to supply the ink jet ink composition and the treatment liquid to the ink jet head  2  includes a plurality of independent cartridges. The cartridge  12  is detachably fitted to the carriage  9  mounting the ink jet head  2 . In the respective cartridges, different types of ink jet ink compositions and the treatment liquid are filled, and the ink jet ink compositions and the treatment liquid are supplied to respective nozzles from the cartridge  12 . In addition, in this embodiment, although the case in which the cartridge  12  is fitted to the carriage  9  is shown by way of example, the cartridge  12  is not limited thereto and may be provided at a position other than that of the carriage  9  so that the ink jet ink compositions and the treatment liquid are each supplied to the nozzle by a supply tube not shown. 
     For the ejection by the ink jet head  2 , a known method may be used. In this embodiment, a method to eject a liquid droplet using vibration of a piezoelectric element, that is, an ejection method to form an ink droplet by a mechanical deformation of an electrostrictive element, is used. 
     The ink jet recording apparatus  1  includes the ventilation fan  8 , the IR heater  3 , and the platen heater  4  each of which is used to dry the ink jet ink composition ejected from the ink jet head  2  and adhered to the recording medium M. By appropriately using the ventilation fan  8 , the IR heater  3 , and the platen heater  4  in combination, the primary drying step can be performed. Furthermore, in the primary drying step, the recording medium M is not always required to be heated, and for example, the ventilation fan  8  may only be used to perform ventilation at ordinary temperature. 
     In addition, when the IR heater  3  is used, the recording medium M can be heated using a radiation method to radiate infrared rays from an ink jet head  2  side. Accordingly, although the ink jet head  2  is also liable to be simultaneously heated, compared to the case in which heating is performed from a rear surface of the recording medium M by the platen heater  4  or the like, the temperature can be increased without receiving the influence of the thickness of the recording medium M. In addition, there may be also provided various types of fans (such as the ventilation fan  8 ) to dry the ink on the recording medium M by supplying a hot wind or a wind having the same temperature as that in the environment to the recording medium M. 
     In order to perform drying at an early stage after the treatment liquid or the ink jet ink composition ejected from the ink jet head  2  is adhered to the recording medium M, the platen heater  4  is configured to be able to heat the recording medium M at a position facing the ink jet head  2  with the platen  11  interposed therebetween. The platen heater  4  is able to heat the recording medium M by a conduction method, and in the recording method of this embodiment, the ink jet ink composition can be adhered to the recording medium M thus heated as described above. Hence, the ink jet ink composition can be fixed on the recording medium M at an early stage, and the image quality can be improved. 
     The heating heater  5  dries and solidifies the treatment liquid or the ink jet ink composition adhered to the recording medium M, that is, the heating heater  5  is a secondary heating heater or a secondary drying heater. The heating heater  5  can be used in the post-drying step. Since the heating heater  5  heats the recording medium M on which an image is recorded, for example, moisture contained in the ink jet ink composition is more rapidly evaporated and scattered, and an ink film is formed by the resin to be contained in the ink jet ink composition. As described above, the ink film is tightly fixed or adhered onto the recording medium M so as to have an excellent film forming property, and hence, an image having an excellent high image quality can be obtained in a short time. 
     The ink jet recording apparatus  1  may also include the cooling fan  6 . After the ink jet ink composition recorded on the recording medium M is dried, when the ink jet ink composition on the recording medium M is cooled by the cooling fan  6 , an ink coating film can be formed so as to have an excellent adhesion onto the recording medium M. 
     In addition, the ink jet recording apparatus  1  may also include the pre-heater  7  to heat the recording medium M in advance before the ink jet ink composition is adhered to the recording medium M. Furthermore, the ink jet recording apparatus  1  may also include the ventilation fan  8  so as to more efficiently dry the ink jet ink composition adhered to the recording medium M. 
     At a lower side of the carriage  9 , there are provided the platen  11  to support the recording medium M, the carriage transfer mechanism  13  to transfer the carriage  9  relative to the recording medium M, and the transport device  14  which is a roller to transport the recording medium M in the sub-scanning direction. The operations of the carriage transfer mechanism  13  and the transport device  14  are controlled by the control portion CONT. 
     In  FIGS.  1  and  2   , although the serial type ink jet recording apparatus is shown, a line type ink jet recording apparatus may also be used. 
     The ink jet recording apparatus described above by way of example can be preferably used to perform the recording method according to this embodiment.

In addition, a pigment dispersion liquid prepared as described below in advance was used. In addition, the numerical values of the pigment dispersion liquid and the water-dispersible resin in the tables each represent an effective component amount (solid content basis). 
     Preparation of Pigment Dispersion Liquid 
     In a flask equipped with a dripping funnel, a nitrogen inlet tube, a reflux condenser, a thermometer, and a stirring device, 50 g of methyl ethyl ketone (MEK) was charged, and while nitrogen bubbling was performed, the temperature was increased to 75° C. In addition, a mixture containing monomers, that is, 80 g of butyl methacrylate, 50 g of methyl methacrylate, 15 g of styrene, and 20 g of methacrylic acid; 50 g of MEK, and 500 mg of a polymerization initiator (azoisobutyronitrile/AIBN) was dripped into the flask described above over 3 hours. 
     After the dripping was finished, heating reflux was further performed for 6 hours, and MEK in an amount corresponding to that lost by evaporation was added after spontaneous cooling, so that a resin solution (resin solid content: 50 percent by mass, acid value: 79 mg/KOH, Tg: 65° C.) was obtained. After a predetermined amount of a sodium hydroxide aqueous solution at a concentration of 20 percent by mass was added as a neutralizer to 20 g of the above resin solution to neutralize 100% of a salt forming group, 50 g of a pigment (C.I. Pigment Blue 15: 3) was gradually added with stirring to the neutralized solution and was then kneaded for 2 hours by a bead mill. 
     After 200 g of ion exchange water was added to the kneaded product thus obtained and then stirred, MEK was distilled off by heating in a reduced-pressure atmosphere. Furthermore, the concentration was adjusted by ion exchange water, so that a pigment dispersion liquid (pigment solid content: 20 percent by mass, resin solid content: 5 percent by weight) was obtained. 
     3.2. Preparation of Treatment Liquid 
     After components were charged into a container to have one of the compositions shown in the following Table 4 and were then mixed and stirred together for 2 hours using a magnetic stirrer, filtration was performed using a membrane filter having a pore diameter of 5 μm, so that treatment liquids of Examples were obtained. The numerical values in the following Table 4 each represent percent by mass, and pure water was added so that a total mass of the treatment liquid was 100 percent by mass. In addition, the numerical value of the cationic resin in the table represents an effective component amount (solid content basis).

     3.4. Evaluation Method 
     In each of Examples and Comparative Examples, evaluation tests of the abrasion resistance, the image quality (wet spreadability), the clogging recovery property, and the storage stability were performed. Hereinafter, the evaluation methods will be described. 
     3.4.1. Abrasion Resistance 
     Under the recording conditions described above and in accordance with the contents shown in Table 5, a solid pattern (color ink adhesion amount: 12 mg/inch 2 , treatment liquid adhesion amount: 1 mg/inch 2 ) was printed on the recording medium and was then left for 30 minutes at room temperature. Subsequently, an ink adhesion portion was cut into a rectangular shape of 30×150 mm and was then rubbed 100 times with a plain-woven cloth using a Gakushin-type fastness rubbing tester (load: 500 g), and a peeling degree of the ink was evaluated by visual inspection. The evaluation criteria were as shown below. 
     Evaluation Criteria 
     AA: No peeling is observed.
 
A: Less than 20% of evaluation area is peeled off.
 
B: Less than 50% of evaluation area is peeled off.
 
C: 50% or more of evaluation area is peeled off.
 
     3.4.2. Image Quality (Wet Spreadability) 
     Under the recording conditions described above and in accordance with the contents shown in Table 5, a solid pattern (patch pattern in duty increments of 10% when a color ink adhesion amount of 20 mg/inch 2  was assumed as a duty of 100%, and a treatment liquid adhesion amount was set to 10 percent by mass of that of the color ink adhesion amount) was printed, and a printed matter thus obtained was then observed by visual inspection. The evaluation criteria were as shown below. 
     Evaluation Criteria 
     AA: No stripe-shaped density irregularity (banding irregularity) extended in main scanning direction is observed.
 
A: Although banding irregularity is slightly observed, density difference is small and inconspicuous.
 
B: Banding irregularity is observed, and density difference is significant but acceptable.
 
C: Banding irregularity is observed, and density difference is significant and conspicuous.
 
     3.4.3. Clogging Recovery Property 
     Under the recording conditions described above and in accordance with the contents shown in Table 5, a recording apparatus was prepared. After the color ink was filled in “SC-R5050”, nozzle missing was intentionally generated by patting a nozzle surface with a Bemcot cloth wetted with water. Under the conditions described above, idle running was performed for 3 hours under the paper face temperature condition shown in Table 5. After the recording was performed, cleaning was performed 3 times, and the number of non-recovered nozzles was counted. By one cleaning, one gram of the ink was ejected from a nozzle group. The nozzle group was formed from 800 nozzles (the treatment liquid was excluded from the evaluation). The evaluation criteria were as shown below. 
     Evaluation Criteria 
     AA: No-ejection nozzles are not observed.
 
A: No-ejection nozzles are less than 1%.
 
B: No-ejection nozzles are 1% to less than 3%.
 
C: No-ejection nozzles are 3% or more.
 
     3.4.4. Storage Stability 
     After 30 g of the color ink of each of Examples and Comparative Examples was sealed in an aluminum pack so as not to incorporate air bubbles, this aluminum pack was left in a temperature-constant bath at 60° C. for 6 days. After the aluminum pack was recovered from the bath and then spontaneously cooled, a viscosity of the color ink was measured at a shear rate of 200 sec −1  using a rheometer (MCR702, manufactured by Anton Paar) and was then compared with a viscosity thereof at an initial stage (immediately after the ink preparation), so that a viscosity increase rate was calculated. The evaluation criteria were as shown below. 
     Evaluation Criteria 
     A: viscosity increase rate is less than 3%.
 
B: viscosity increase rate is 3% to less than 5%.
 
C: viscosity increase rate is 5% or more.
 
     3.5. Evaluation Results 
     The evaluation results are shown in Table 5. 
     From Table 5, it was found that the image quality (wet spreadability), the abrasion resistance, the clogging recovery property, and the storage stability are excellent in all Examples in each of which the water-based ink jet ink composition includes the colorant, the amine, and the water-soluble low molecular weight organic compound and is used for recording on a non-absorbing recording medium or a low-absorbing recording medium, the water-soluble low molecular weight organic compound contains an alkylene glycol monoether (B) represented by general formula (1) having a standard boiling point of 210° C. or less and an alkanediol (A) having a standard boiling point of 210° C. or less at a mass ratio (B/A) of 0.2 to 0.9, a content of a water-soluble low molecular weight organic compound having a standard boiling point of 250° C. or less is 8 to 30 percent by mass with respect to the total mass of the ink composition, a water-soluble low molecular weight organic compound which is an alkane polyol having a standard boiling point of more than 250° C. is not contained at a content of more than 3 percent by mass with respect to the total mass of the ink composition, and a content of the amine with respect to the total mass of the ink composition is 5 percent by mass or less. 
     As apparent from comparison of Examples 1 to 3 with Comparative Examples 1 to 2, when the content of the water-soluble low molecular weight organic compound having a standard boiling point of 250° C. or less is in a predetermined range, the abrasion resistance, the image quality (wet spreadability), and the clogging recovery property are excellent. 
     As apparent from comparison of Examples 1 and 4 with Comparative Example 3, when the mass ratio (B/A) is a predetermined value or less, the storage stability is excellent. 
     In addition, as apparent from comparison of Example 1 with Comparative Example 9, when the mass ratio (B/A) is a predetermined value or more, the image quality (wet spreadability) and the clogging recovery property are excellent. 
     As apparent from comparison of Examples 1 and 9 to 12 with Comparative Example 4, when the alkylene glycol monoether (B) represented by the general formula (1) having a standard boiling point of 210° C. or less is contained, the image quality (wet spreadability) is excellent. 
     As apparent from comparison of Examples 1 and 8 with Comparative Examples 5 and 10, when the alkanediol (A) having a standard boiling point of 210° C. or less is contained, the clogging recovery property and the storage stability are excellent. 
     As apparent from comparison of Example 1 with Comparative Example 6, when the water-soluble low molecular weight organic compound which is an alkane polyol having a standard boiling point of more than 250° C. is not contained in more than a specific amount, the abrasion resistance is excellent. 
     As apparent from comparison of Examples 1 and 5 to 6 with Comparative Example 7, when the content of the amine is a predetermined value or less, the abrasion resistance is excellent. 
     As apparent from comparison of Examples 1 and 13 to 17 with Comparative Example 8, when the amine is contained, the clogging recovery property is excellent. 
     As apparent from the results of Examples 1 to 4, when the content of the alkylene glycol monoether (B) represented by the general formula (1) having a standard boiling point of 210° C. or less is a predetermined value or more, the wet spreadability of the ink to the low-absorbing recording medium or the non-absorbing recording medium is improved, and the image quality (wet spreadability) tends to be made more excellent. In addition, when the content described above is a predetermined value or less, while a preferable drying property is secured, the dispersion stability is not likely to be degraded, and hence, the clogging recovery property, the abrasion resistance, and the dispersion stability tend to be made more excellent. 
     As apparent from the results of Examples 1 and 9 to 12, by various compounds of the alkylene glycol monoether (B) represented by the general formula (1) having a standard boiling point of 210° C. or less, the image quality (wet spreadability), the abrasion resistance, the clogging recovery property, and the storage stability are excellent. 
     As apparent from the results of Examples 1 and 13 to 14 and Examples 15 to 17, when the amine is an alkanolamine having a standard boiling point of 270° C. or more, the moisture retaining property is made more excellent, and in addition, a preferable drying property tends to be secured, so that the clogging recovery property and the abrasion resistance tend to be made more preferable with good balance. 
     As apparent from the results of Examples 1 to 4, when the content of the alkanediol (A) having a standard boiling point of 210° C. or less is a predetermined value or more, the moisture retaining property is made more excellent, and the clogging recovery property tends to be more likely to be improved. In addition, the dispersion stability tends to be not likely to be degraded, and the storage stability is more likely to be made more preferable. Furthermore, when the content of the alkanediol (A) is a predetermined value or less, since the drying property is likely to be secured, the abrasion resistance tends to be made more excellent. 
     As apparent from the results of Examples 1, 18, and 20 to 22, as the water-soluble low molecular weight organic compound, when at least one selected from the amide, the sulfur-containing solvent, and the cyclic ether is contained in a specific range, the abrasion resistance tends to be improved. 
     As apparent from the results of Examples 18 and 23 to 24, when the surfactant is contained in a predetermined range, the abrasion resistance, the image quality (wet spreadability), and the clogging recovery property tend to be made more excellent with good balance. 
     In addition, although not shown in the table, when recording was performed on regular paper (neither the non-absorbing recording medium nor the low-absorbing recording medium) using the ink H in a manner similar to that of Comparative Example 4, since the ink was absorbed and spread in the recording medium, the wet spreadability was excellent; however, the abrasion resistance of the recorded matter was inferior. From the result thus obtained, it was found that when the recording is performed on the non-absorbing recording medium or the low-absorbing recording medium, the wet spreadability is a problem. 
     From the embodiments described above, the following conclusions are obtained.
