Prevents localization on the surface of the recording medium and can easily improve the adhesion between the colorant aggregates and the paper surface on the recording medium, and the scratch resistance of the printed area after printing. It becomes. It is presumed that the above-mentioned effects were exhibited by the configuration of the present invention because the reaction liquid and the ink were in the state described below on the recording medium.
- FIG. 4 is a conceptual diagram showing a state until a (printed matter) is formed.
- the ink droplet 1 After the ink droplet 1 lands on the recording medium, it penetrates in the depth direction of the recording medium in the order of 1 A ⁇ 1 B ⁇ 1 C ⁇ 1 D, and forms an aggregate by the reaction between the pigment 3 and the polyvalent metal.
- the ink droplet 1 reacts while gradually penetrating in the depth direction of the recording medium to form an aggregate. Therefore, aggregates are not localized, and aggregates are distributed at a certain depth from the surface.
- the reaction between the pigment dispersion and the polyvalent metal occurs, A certain amount of the pigment dispersion reacts with the polyvalent metal near the surface, and the rest of the pigment dispersion continues to penetrate further in the depth direction of the recording medium to a position deeper than the polyvalent metal reacted in the state of 1B. Reacts with assigned polyvalent metals (1C). Further, the same occurs in the state of 1 C, and the state shifts to the state of 1 D.
- 2A to 2C show the process of forming aggregates distributed at a certain depth from the recording medium surface 4 in more detail.
- an aggregation reaction between the pigment 3 and the polyvalent metal 5 starts on the recording medium surface 4 as the ink permeates (state 2A).
- the pigment 3 reaches around the polyvalent metal 5 on the surface layer of the recording medium in the figure, the pigment 3 and the polyvalent metal 5 aggregate.
- the polyvalent metal 5 existing near the surface reacts with a certain amount of the pigment dispersion.
- the reactivity of the polyvalent metal 5 that has reacted with the pigment dispersion decreases, so that all the pigments 3 near the surface layer of the recording medium do not react in a chain. That is, in the vicinity of the polyvalent metal 5 on the surface layer of the recording medium shown in the figure, a certain amount of the aggregate that has reacted with the pigment dispersion and the unreacted pigment dispersion are present, resulting in a 2B state. After that, the unreacted pigment dispersion penetrates more in the depth direction of the recording medium, reaches the vicinity of the polyvalent metal inside the recording medium in the figure, forms an aggregate, and shifts to a 2C state. Repeating such partial aggregation and permeation, as shown in Figure 1D Pigment aggregates (printed matter) distributed at a certain depth from the surface 4 of the recording medium.
- a major difference between the conventional system for forming an image using an aqueous ink and a reaction liquid and the present invention is that a substance having a binder function in the ink (excluding a dispersant for ensuring the dispersion stability of the pigment) is used. Even if it is not contained, the scratch resistance of the recorded matter can be improved by controlling the reactivity between the coloring material in the ink and the reaction component in the reaction liquid.
- the reactivity between the coloring material in the ink and the reaction component in the reaction solution is improved in order to improve the bleeding and fixability of the obtained image. Increases and rapidly forms aggregates.
- an ink containing a styrene-acrylic acid copolymer having an acid value of about 210 which is disclosed in Examples of Japanese Patent Application Laid-open No.
- the most important point of the present invention is to find a method that controls the reactivity between the aqueous ink and the reaction liquid, which has not been considered as a means for improving the scratch resistance when a two-liquid system is used. It is in.
- the ink and the reaction liquid of the present invention which are precisely controlled so as to obtain a slightly lower reactivity than the conventional ink and the reaction liquid, were used.
- the liquid penetration rate and the rate at which agglomerates are formed more reactive components are present in the surface layer of the recording medium before the ink is applied to the recording medium. Is more preferable. That is, the most important point of the present invention, that the aggregates are distributed at a certain depth from the surface layer of the recording medium, the amount of the reaction solution applied and the penetration rate, and further, the reaction solution is applied to the recording medium. It has been found that it can be more easily achieved by defining the time from when the ink is applied until the ink is applied.
- reaction solution of the present invention It is essential that the reactivity between the reaction solution of the present invention and the aqueous ink is controlled to satisfy the following conditions.
- a 500-fold diluted aqueous solution of the reaction solution (50 g) and a 5-fold diluted aqueous solution of the aqueous ink (0.10 g) were added. 3 g, and after 15 minutes, the mixture is filtered through a 0.2 filter.
- the absorbance at the maximum absorption wavelength in the visible region (when carbon black is used as the pigment, the wavelength is 55 nm) is shown in (A).
- the absorbance at the maximum absorption wavelength in the visible region of a mixed solution of 0.3 g of the aqueous ink and a 50-fold diluted water of 50 g of pure water is defined as (B)
- Polymeric dispersants can be generally used, and from the viewpoint of facilitating functional design of the dispersant, monomer components having radically polymerizable unsaturated bonds such as acryl resin and styrene-no-acrylic resin are used. Polymers or copolymers are preferred.
- monomer components having radically polymerizable unsaturated bonds such as acryl resin and styrene-no-acrylic resin are used. Polymers or copolymers are preferred.
- an anion component for obtaining an anionic property that reacts with a polyvalent metal there is a reactivity between the reaction liquid and the ink. It is more preferable to include a component to be controlled within the range.
- Components that control the reactivity between the reaction liquid and the ink within a certain range include nonionic substituents having high hydrophilicity such as a hydroxyl group and an ether group such as polyethylene ether.
- a (meth) acrylic acid ester having a substituent of polyethylene glycol as shown in the formula (1) is used to obtain a monomer component. Adjustment of the copolymerizability ratio of By changing the length of one ter chain (repeating unit), the reactivity with a polyvalent metal can be arbitrarily controlled, which is preferable.
- the reason why it is possible to control the reactivity between the aqueous ink and the reaction solution by including a monomer having a highly hydrophilic nonionic substituent in the polymer dispersant is presumed as follows. You. The monomer having anionic properties in a solution has a different degree of reactivity, but a reactive action occurs upon contact with a cationic substance such as a polyvalent metal ion. It is very difficult to define the reactivity between the aqueous ink and the reaction liquid as described above.
- a monomer that does not have ionicity in a solution may cause a reaction even when brought into contact with a cationic substance such as a polyvalent metal ion. Absent. Therefore, it is possible to easily control the reactivity between the aqueous ink and the reaction solution delicately as in the present invention.
- a monomer having a nonionic substituent that does not react even when it comes into contact with the reaction liquid does not form a film at the moment when the ink is applied to the recording medium, and the liquid component in the recording medium does not form.

- Monomers and salts thereof, and monomers having a phosphonic acid group such as ethyl methacrylate-2-ethyl phosphonate, ethyl acrylate-2-ethyl phosphonate and the like can be mentioned. Among these, it is particularly preferable to use acrylic acid and methacrylic acid. These monomers can be used alone or in combination of two or more.
- the anionic polymer dispersant preferably has an acid value in the range of 100 to 400.
- the acid value is less than 100, the polymer does not dissolve in an aqueous medium, In some cases, the dispersion stability of the pigment dispersion dispersed in the above is poor, and an aggregate may be formed.

Therefore, when applying the reaction liquid and the aqueous ink to the recording medium, it is preferable that the reaction liquid is applied at least to the area of the recording medium to which the aqueous ink is applied, and the aqueous ink is applied. More preferably, the reaction liquid is applied to an area wider than the area of the recording medium.

- the present inventors In the process of conducting various studies on a system for forming an image using two liquids, the present inventors have found that in order to obtain a high-quality image and at the same time to provide a recorded matter having good scratch resistance, The following conditions were found to be important. In other words, the location of the agglomerates formed by the pigment and the polyvalent metal contacting on the recording medium in the recording medium is set to a certain region, specifically, a little in the depth direction from the surface layer of the recording medium. It is extremely important to form more aggregates within the sinking position, that is, within about 30 m from the surface to the depth.
- a reaction liquid and an ink on a recording medium there are various methods for contacting a reaction liquid and an ink on a recording medium.
- the present inventors require that the aqueous ink and the reaction liquid be mutually separated on the recording medium. It was concluded that the contact method in the liquid state was the best. Specifically, the method of applying the aqueous ink after the fixing of the reaction liquid is superior to the method of applying the aqueous ink and the reaction liquid almost simultaneously on the recording medium by the inkjet recording method is superior. The reason why the method of applying the aqueous ink after the fixing of the reaction liquid on the recording medium is excellent in the scratch resistance is presumed as follows.
- the reaction liquid and the aqueous ink come into contact with each other in a liquid state on the recording medium, the stronger the reactivity between the ink and the reaction liquid, the more the coloring material aggregates on the surface layer of the recording medium. As a result, an image having excellent coloration properties can be obtained, but the image fastness may not be sufficient.
- the ink is applied after the reaction liquid has been fixed to the recording medium, the reaction components contained in the reaction liquid are deeper than the surface layer of the recording medium because most of the reaction components are present inside the recording medium. Agglomerates of many coloring materials are formed at positions slightly sinking in the direction. As a result, it is considered that the two liquids are more excellent in abrasion resistance than in a liquid state on the recording medium.
- the time when fixing is completed means that the value of Ka (t-tw) 1/2 in the following formula (a) is larger than the amount of the reaction solution actually applied to the paper surface. It means the time when it became sharp. This means a point in time when the droplet of the reaction liquid has been absorbed into the recording medium, and a time after t seconds calculated from the Ka value by the Bristow method and the applied amount of the liquid composition.
- V V r + K a ( ⁇ tw) 1/2 formula (a)
- the reaction liquid immediately after the reaction liquid adheres to the surface of the recording medium, the reaction liquid is mostly absorbed in the uneven portions of the recording medium surface (the surface roughness of the recording medium). Almost no permeation into the recording medium.
- the time during that time is the contact time (tW), and the amount of the reaction solution absorbed by the uneven portions of the recording medium during the contact time is Vr.
- the contact time exceeds the contact time after the reaction liquid has adhered to the recording medium, the time over the contact time, that is, (t-tw) is proportional to 1 Z 2 raised to the recording medium.
- Ka is a proportional coefficient of this increase, and shows a value corresponding to the permeation rate.
- the Ka value can be measured using a liquid dynamic permeability tester (for example, trade name: dynamic permeability tester S; manufactured by Toyo Seiki Seisakusho) by the Bristow method.
- the Ka value according to the Bristow method in the present invention is as follows: “for plain paper [for example, a copier or page printer (laser beam printer) using an electrophotographic method manufactured by Canon Inc.) or a printer using an ink jet recording method.
- PB paper used as a paper, PPC paper which is a paper for copying machines using electrophotography, etc.] is measured as a recording medium.
- the measurement environment is assumed to be a normal office environment, for example, a temperature of 20 to 25 ° C and a humidity of 40 to 60%.
- the reaction liquid comes into contact with the recording medium, it penetrates along the fibers of the recording medium under the influence of the solvent or surfactant, etc. It is speculated that some of the metal begins to precipitate. Therefore, in order for many polyvalent metals to be located slightly below the surface of the recording medium in the depth direction, it is important to apply a reaction liquid with a certain penetration rate to the recording medium as little as possible. It is. From the above, the permeability of the reaction solution to plain paper in the present invention is such that the Ka value determined by the Bristow method is 1.3 mL ⁇ ' 2 ' msec ⁇ 1/2 or more, and the coating amount is 0.
- K a value greater than 3. 0 m L ⁇ m_ 2 ⁇ msec- 1/2, further application amount 2. 0 g Zm 2 or 3.0 g Zm 2 or less is more preferable.
- the point of the present invention is to distribute the aggregate formed by the contact between the reaction liquid and the aqueous ink at a certain depth from the surface layer of the recording medium without localizing on the surface of the recording medium. In order to obtain such a state, it is most important that the reactivity between the reaction solution and the aqueous ink is set to the value specified in the present invention.
- the present invention can be realized more effectively by controlling the time from when the recording medium is applied to when the ink is applied. In a conventional system for forming an image using a reaction liquid and water-based ink, not only is the reaction between the reaction liquid and the water-based ink of the present invention stronger, but also the above-described reactivity control is performed. There is no system.
- Examples of the method for applying the reaction liquid to the recording medium according to the present invention include a method using an ink jet recording method as in the case of the ink, and a method of applying the reaction liquid of the present invention to the recording medium by a mouth or the like. .
- application by a roller or the like which does not need to consider the dischargeability and the like is preferable.
- a specific application method will be described later.
- the amount of the reaction liquid applied to the recording medium by a roller or the like depends on the physical properties of the reaction liquid, the rotation speed of the roller used in the coating device, and the recording of the roller. It can be appropriately adjusted by the contact pressure to the medium and the like.
- the set of the reaction liquid and the aqueous ink according to the present invention is particularly preferably used for inkjet recording.
- Ink jet recording methods include a recording method in which mechanical energy is applied to the ink to eject droplets, and a recording method in which thermal energy is applied to the ink to eject droplets by bubbling of the ink.
- the ink and reaction liquid of the present invention can also be used. In this case, it is preferable that the reaction liquid and the ink having the above-described configuration according to the present invention have characteristics that can be ejected from the ink jet head.
- the properties of these liquids are, for example, their viscosity is l ⁇ 15mPas, the surface tension is more than 25mN / m (dyn e / cm), especially the viscosity It is preferable to set the surface tension to 1 to 5 mPa ⁇ s and the surface tension to 25 to 5 OmN / m (dyne / cm).
- the reaction liquid is applied at least to the printing area of the recording medium to which the ink is applied, so that the surface tension is 25 to 35 mN / m (dyne / cm) or less. Is preferred.
- the surface tension of the reaction liquid is 2 OmNZm (dyn eXcm) or more, the viscosity is 100 CPS or less, and particularly, the surface tension is 25 mN. It is desirable that the viscosity be 5 mPS / m (dyne / cm) or more and 35 mN / m (dyne / cm) or less and the viscosity is 5 CPS or more and 60 CPS or less in terms of controlling the applied amount and uniform application onto the recording medium.
