- FIG. 3 (a), (b), (c), (d), (e) and (f) show the basic concept of the present invention.
- FIG. 3 (a) shows a process in which the reaction liquid 20 is brought into contact with the pigment ink 30 on the upper surface of the recording medium 10, and the pigment is applied to the recording medium 10 to which the reaction liquid 20 has been applied in advance. The moment when the ink 30 is applied and comes into contact with the reaction liquid 20 is shown.
- the reaction liquid and the pigment ink are contacted in a liquid state.
- the permeability of the pigment ink is higher than the permeability of the reaction liquid.
- the surface tension of the pigment ink is lower than the surface tension of the reaction solution.
- the relationship between the surface forces can be adjusted, for example, by changing the content ratio of the surfactant in the reaction liquid and the pigment ink.
- the method of applying the reaction solution 20 is not particularly defined in the present invention, but the application by the well-known ink jet method can be suitably used. Further, in order to bring the reaction liquid 20 and the pigment ink 30 into contact with each other on the upper surface of the recording medium 10, the pigment ink 3 is applied before the reaction liquid 20 applied to the recording medium 10 permeates the recording medium 10. 0 must be assigned. In other words, the pigment ink is brought into contact with the reaction liquid in a liquid state on the upper surface of the recording medium. This is one of the features of the present invention. In order to realize this, it is preferable to use a reaction solution 20 having low permeability. If the reaction liquid 20 has low permeability to the recording medium 10, it is possible to set a certain amount of time until the pigment ink 30 is applied, so that it is easy to set suitable printing conditions.
- Making the reaction solution 20 low in permeability to the recording medium 10 can be achieved by suppressing the addition amount of a surfactant or the like serving as a penetration enhancer.
- a surfactant or the like serving as a penetration enhancer.
- the Bliss I method As one method for evaluating the permeability of the reaction solution 20 to the recording medium 10, there is the Bliss I method.
- the Bristol method is described in JAP AN TA PPI Paper and Pulp Test Method No. 51, “Test Method for Liquid Absorbency of Paper and Paperboard”, wetting time Tw, absorption coefficient K a (mL / m2-msi / 2 ) And the roughness index V r (mLZm2) are defined and described in many sales books, so detailed description is omitted here, but Fig. 4 shows only an example of an absorption curve.
- the reaction liquid 20 starts to permeate the recording medium 10 from the time when the wetting time Tw has elapsed. Therefore, by applying the pigment ink 30 and bringing it into contact with the reaction liquid 20 by the time when the permeation is not completely completed, the reaction existing on the upper surface of the recording medium can be achieved. The pigment ink can be brought into contact with the liquid interface.
- reaction liquid 10 and the pigment ink 30 are brought into contact with each other on or above the recording medium 10.
- the liquid absorbency of various types of plain paper can be controlled mainly by the surface tension of the liquid, and the landing time difference Td is several milliseconds or more in a general inkjet recording method. Therefore, the surface tension of the reaction solution is desirably 35 mN / m to 6 OmNZm.
- FIGS. 3 (b), (c) and (d) show a step of forming a film-like aggregate 31c on the interface where the reaction liquid and the pigment ink come into contact.
- This step is to form a film-like aggregate 31c formed by aggregating the pigment aggregates 31b immediately after the previous step, which is one of the features of the present invention.
- the manner in which the aggregates 31b aggregate to form the film-like aggregates 31c will be described later in detail with reference to FIGS. 5 (a), (b), (c) and (d).
- the pigment ink 3 To form the aggregates 31b constituting the film-like aggregates 31c, the pigment ink 3
- the most suitable method is to include polyvalent metal ions in the reaction solution to cause coagulation. It is also possible to use a method in which an organic substance is contained and aggregated.
- the polyvalent metal ions 21 contained in the reaction liquid collide with carboxylate ions, sulfonate ions, phosphate ions, etc. in the pigment ink 30 to cause a reaction, thereby reducing the dispersibility of the pigment. And consequently causes agglomeration of the pigment.
- the aggregation of the pigment is more likely to occur as the probability of the collision increases. Therefore, it is preferable that the polyvalent metal ion 21 contained in the reaction liquid 20 be contained more than the total charge concentration of the opposite polarity ion that reacts with the polyvalent metal ion 21 in the pigment ink 30.
- the total charge concentration refers to the number of polyvalent metal ions per unit mass in the reaction solution, and the opposite polarity ions such as carboxylate, sulfonate, and phosphate ions per unit mass in the pigment ink. Is defined by the number.
- FIGS. 5 (a) to 5 (d) are enlarged views of the parts indicated by broken lines in FIGS. 3 (b) to 3 (d).
- the aggregates 31b formed immediately after the pigment ink 30 comes into contact with the reaction solution 20 move along the surface of the reaction solution 20 with the surfactant 32. I will do it.
- the reason why the aggregates 3 1b and the surfactant 32 move on the surface of the reaction solution 20 is that the content of the surfactant 32 in the pigment ink 30 is increased.
- FIGS. 3 (e) and (f) show a process for promoting the permeability of the reaction solution 20 into the recording medium 10 and a process for fixing the film-like aggregates 31c to the surface of the recording medium 10. The steps that proceed almost simultaneously are shown in chronological order.
- the penetration enhancer and the solvent typified by the surfactant 32 contained in the pigment ink 30 diffuse into the reaction solution 20, and with this diffusion, the permeability of the reaction solution increases. As a result, the solvent component in the reaction liquid 20 and the solvent component in the pigment ink 30 rapidly permeate the recording medium 10.
- Such a diffusion of the penetration enhancer and a change in the permeability of the reaction solution are another feature of the present invention.
- the state in which this process has progressed is shown in FIG. 3 (e), and finally, as shown in FIG. 3 (f), the film-like aggregate 31 c is formed on the recording medium 10 (for example, And fix it so as to cover the surface of the plain paper composed of the above fibers to form the cohesive film 3Id.
- the surface of plain paper has undulations due to fiber irregularities, as shown in Fig. 6 (a)
- the film-like aggregates 31c are formed, the The solvent component and the solvent component in the pigment ink 30 quickly penetrate into the recording medium 10 and follow the undulations of the fiber irregularities as shown in Fig. 6 (b).
- Fig. 8 (a) is an electron micrograph of the plain paper surface without printing. According to the actual recording method of the present invention, as shown in Fig. 8 (c), the aggregated film 31d is usually used. Cover the paper surface. According to FIG. 8 (c), it can be seen that the aggregated film 31 d covers a plurality of fibers and covers the plurality of fibers, and that the aggregated film 31 d has cracks.
- the mixed liquid component of the reaction liquid 20 and the pigment ink 30 quickly penetrates into the recording medium 10, and the film-like aggregates 31c are quickly fixed on the surface of the recording medium.
- Fast fixing can be achieved.
- high color developability can be achieved by the film-like aggregate aggregate film 31d fixed so as to cover the surface of the recording medium.
- one of the features is that the reaction liquid 20 and the pigment ink 30 are brought into contact with each other on the upper surface of the recording medium 10.
- the case where the reaction solution and the ink are brought into contact with each other at a position other than the top surface of 0 will be described.
- the reaction liquid 20 is impregnated into the recording medium 10 and brought into contact with the pigment ink 30, most of the reaction occurs in the recording medium 10, so that the distribution of the pigment particles is more inside the surface of the recording medium 10.
- the formation of aggregates 31b at the interface of the reaction solution does not occur. Aggregates 31c of the above cannot be formed, and for this reason, high color development cannot be obtained.
- one of the characteristic features is that a film-like aggregate 31c is formed by aggregating the aggregates 31b. That is, a case where the film-like aggregate 31c is not formed will be described. Even if the pigment particles lose electrical repulsion and aggregate, they do not form a film and may maintain the state of aggregates 31b. According to the study of the present inventors, the size of the aggregates 31b is often 1 or less, and in such a state, as the reaction liquid 20 and the liquid component of the pigment ink 30 penetrate, As shown in FIG. 7, it has been found that most of the aggregates 31b flow between the fibers of the recording medium 10 together with the liquid component. For this reason, even if the fixing property is excellent, there is a possibility that a recorded matter having low coloring property may be obtained.
- Fig. 8 (b) is an electron micrograph when the aggregates 3 1b flowed between the fibers of plain paper, but it was observed that there was not much difference from Fig. 8 (a). As shown in c), the aggregated film 31d was not formed, and the recorded material had low coloring.
- another feature of the present invention is a change in the permeability of the reaction solution due to the diffusion of the penetration enhancer in the pigment ink into the reaction solution 10. If not diffused into the liquid 10, the permeability of the reaction liquid does not change, and the liquid component of the pigment ink 30 is retained on the film-like aggregate 31c. For this reason, the printing unit has to dry the solvent for a long time, which causes a problem that the fixing property is lowered. The same applies to the case where the pigment ink does not have a penetration enhancer.Since the permeability of the reaction solution 20 does not change, the printing portion retains the liquid for a long time, causing a problem that the fixability decreases. I do.
- the most suitable reactant that reacts with the pigment ink contained in the reaction liquid in the present invention is a polyvalent metal salt.
