Definitions
- the present invention belongs to the technical field of an ink jet recording ink suitable for ink jet recording, a solvent used for the ink, a cartridge provided with the ink and a recording apparatus. Background art
- an ink containing a coloring material such as a dye or a pigment, a humectant, a penetrant, and water
- a coloring material such as a dye or a pigment, a humectant, a penetrant
- water resistance of the image becomes a problem.
- Plain paper especially a wide range of commercially available paper, especially paper used in electrophotographic copiers, intended to have the optimal structure, composition, characteristics, etc. for inkjet recording
- the ink containing the hydrolyzable silane compound as described above is used as it is.
- the rate at which the solvent such as water in the ink droplets evaporates and penetrates into the recording medium is relatively slow, and the condensation polymerization reaction of the silane compound is performed. Is not performed promptly, which results in insufficient surrounding of the coloring material by the silane compound.
- this image becomes wet immediately after forming the image on the recording medium, the coloring material not surrounded by the silane compound will seep into the water, and the effect of improving the water resistance will be sufficiently obtained. There is a problem that can not be.
- the present invention has been made in view of such a point, and an object of the present invention is to provide an ink containing a water-soluble substance that undergoes a polycondensation reaction in the absence of water, such as the above-mentioned hydrolyzable silane compound.
- the purpose of the present invention is to improve the water resistance of an image when an image is formed by the method, particularly to improve the water resistance immediately after the image is formed. Disclosure of the invention
- the surface tension of ink or a solvent is set to a relatively low value, or the ink has a boiling point of 100 Fluoroalkyl monoalcohols lower than ° C were included.
- an ink jet recording medium containing a solvent containing a humectant, a penetrant, and water, a coloring material, and the water-soluble substance that undergoes a polycondensation reaction in the absence of water.
- the ink surface tension at 25 ° C before the condensation reaction of the water-soluble substance was set to 20 to 5 OmN / m (20 to 50 dyn / cm) for the ink. It is assumed that
- the surface tension of the ink is set to a relatively low value of 5 OmN / m or less, after the ink droplet adheres to the recording medium (for example, paper), the solvent such as water in the ink droplet is removed. It easily permeates into the recording medium. As a result, the condensation polymerization reaction of the water-soluble substance is rapidly performed, and the water-soluble substance quickly and surely surrounds the coloring material (dye, pigment, etc.). Therefore, even if the image is wetted with water immediately after forming the image on the recording medium by this ink, the coloring material of the ink permeates into the water because it is surrounded by the water-soluble substance that has undergone the condensation polymerization reaction. There is very little. Therefore, the water resistance of the image can be reliably improved. In addition, this The surface tension of the ink can be easily adjusted by adjusting the content of the penetrant.
- the surface tension of the ink is preferably as low as possible from the viewpoint of promptly penetrating the solvent into the recording medium, but if the surface tension is smaller than 2 OmN / m, the ink is formed into a droplet. Therefore, it is not preferable for ink jet recording, and therefore, it is set to 2 OmN / m or more.
- the ink surface tension at 25 ° C. before the water-soluble substance undergoes the condensation polymerization reaction is 30 to 40 mN / m (30 to 40 dyn). / cm).
- the piezoelectric element of the piezoelectric actuator for ejecting ink droplets provided in the ink jet head of the recording apparatus.
- the ink jet head is constituted by a pressure chamber containing ink, a nozzle communicating with the pressure chamber, and a piezoelectric actuator that deforms radially so that the pressure of the ink chamber increases or decreases
- the piezoelectric actuator is deformed radially so that the pressure in the pressure chamber increases, and the ink is discharged from the nozzles.
- the piezoelectric actuator is rapidly deformed (in a retraction direction opposite to the ink extrusion direction) so that the pressure in the pressure chamber is reduced, thereby being extruded from the nozzle.
- the ejected ink is torn off from the ink in the pressure chamber to eject the ink droplets.
- the piezoelectric element of the piezoelectric actuator is a thick-film piezoelectric element having a thickness of, for example, 10 ⁇ m or more, the force generated when the piezoelectric element is pulled back is deformed.
- the ink Since the ink is relatively large, the ink can be torn off even if the surface tension of the ink is relatively low, whereby an ink droplet is formed and ejected from the nozzle.
- the thickness of the piezoelectric element is small, the force generated during the retraction deformation of the piezoelectric actuator is small, so that if the surface tension of the ink is low, the ink cannot be torn off. As a result, ink drops cannot be formed.
- the pressure element Even if the film is a thin film, the ink can be torn off, so that the ink droplet can be surely formed and ejected from the nozzle.
- the driving frequency of the piezoelectric actuator can be increased when the piezoelectric element is a thin film.
- the piezoelectric actuator is pulled back and deformed, ink is sucked in from the ink force communicating with the pressure chamber and the ink is filled into the pressure chamber, but when the piezoelectric element is a thin film.
- the time between the ejection of the ink droplet and the ejection of the next ink droplet becomes longer, and as a result, the driving frequency of the piezoelectric actuator decreases.
- the surface tension of the ink is set to 4 OmN Zm or less as in the present invention, even if the piezoelectric element is a thin film, the ink is smoothly sucked into the pressure chamber. It is possible to drive the piezoelectric actuator at a high frequency of kHz or higher to eject ink droplets.
- the solvent quickly penetrates into the recording medium, and the color material is quickly and reliably formed by the condensation polymerization reaction of the water-soluble substance. Surrounded by high water resistance.
- the ink viscosity at 25 ° C. before the water-soluble substance undergoes the condensation polymerization reaction is set to 2 to 10 cP.
- the viscosity of the ink is relatively low, that is, 10 cP or less, the solvent can be more quickly permeated into the recording medium. As a result, the water resistance immediately after image formation is further improved.
- the above viscosity is preferably as low as possible from the viewpoint of promptly penetrating the solvent into the recording medium, but since the viscosity of water is about 1 cP, in addition to this water, a coloring material, a humectant, The lower limit of the viscosity of the ink containing the agent and the water-soluble substance is 2 cP.

Further, since the surface tension of the ink is reduced by the inclusion of the fluoroalkyl monoalcohol, water, fluoroalkyl monoalcohol and the like are more easily permeated into the recording medium. Fluoroalkyl monoalcohols, on the other hand, have a lower boiling point than water, so they evaporate more quickly than water and also evaporate after penetrating into the recording medium, inhibiting the condensation polymerization of water-soluble substances.

Have been.
- Each of the piezoelectric actuators 21 is formed by applying a drive voltage to each piezoelectric element 23 via the diaphragm 22 or each intermediate layer 25 and each individual electrode 24.
- Pressure By deforming the portion corresponding to the force chamber 4, the ink in the pressure chamber 4 is discharged from the discharge port 3 b or the nozzle 14. That is, when a pulse-like voltage is applied between the diaphragm 22 and the individual electrode 24, the rise of the pulse voltage causes the piezoelectric element 23 to contract in the width direction perpendicular to the thickness direction due to the piezoelectric effect.
- the diaphragm 22, the individual electrodes 24, and the intermediate layer 25 do not shrink, so the portion corresponding to the pressure chamber 4 of the diaphragm 22 is deformed radially to the pressure chamber 4 side by the so-called bimetal effect. I do. Due to this radial deformation, a pressure is generated in the pressure chamber 4, and the ink in the pressure chamber 4 is pushed out from the nozzle 14 via the discharge port 3b and the discharge ink flow path 12 by this pressure. Then, the piezoelectric element 23 expands due to the fall of the pulse voltage, and the portion corresponding to the pressure chamber 4 of the vibration plate 22 returns to the original state. At this time, the portion is pushed out from the nozzle 14.
- the ink in the ink flow path 12 is torn off from the ink in the ink flow path 12, and is ejected onto the recording paper 41 as an ink droplet having an ejection amount of, for example, 3 p 1, and adheres to the recording paper 41 in the form of dots.

Note that the pulse voltage applied to each piezoelectric element 23 rises from the first voltage to the second voltage lower than the first voltage, even if the pulse voltage is not of the push-pull type as described above. It may be of a push-pull type that rises to the first voltage after dropping.
- the drive voltage is applied to each of the piezoelectric elements 23 during a predetermined time (when the inkjet head 1 and the carriage 31 are moved from one end to the other end of the recording paper 41 in the main scanning direction at a substantially constant speed.
- the operation is performed every 50 / S: drive frequency 20 kHz (however, no voltage is applied when the ink jet head 1 reaches a position where the ink droplet does not land on the recording paper 41). This causes the ink droplet to land on a predetermined position of the recording paper 41.
- the recording paper 41 is conveyed by a predetermined distance in the sub-scanning direction by the conveyance mode and the respective conveyance rollers 42, and the ink jet head 1 and the carriage 31 are again moved in the main scanning direction.
- the ink droplet is ejected while moving to the next position, and recording for one new scan is performed.
- the desired image is An image is formed.

- the humectant suppresses drying at the nozzles 14 of the inkjet head 1 and the like, and the penetrant enhances the permeability of the ink (solvent) into the recording paper 41.
- the above-mentioned silane compound is formed by ink droplets ejected from the nozzle 14 of the above-mentioned ink jet head 1 adhering to the recording paper 41, and evaporating water (solvent) in the ink droplets or recording paper 41. When it permeates into the inside of the recording paper, it undergoes a condensation polymerization reaction on the recording paper 41 and surrounds the coloring material at this time. It works to prevent water seepage and improve the water resistance of the image.
- This is obtained by reacting a monoepoxy compound with a hydrolysis reaction product of an alkoxysilane containing an organic group having an amino group and an alkoxysilane not containing an amino group, or a hydrolyzable silane containing an amino group.
- An organic silicon compound obtained by hydrolyzing a hydrolyzable silane and a hydrolyzable silane containing no nitrogen atom is preferable.
- the coloring material is desirably a dye or a pigment.
- the dye may be any dye, but is preferably a water-soluble acid dye or a direct dye.
- black pigments include those obtained by treating the surface of black pigment with diazo dimethyl salt and those obtained by subjecting a polymer to graft polymerization and surface treatment. And those treated with a surfactant such as a formalin condensate of naphthylene sulfonate, lignisulfonic acid, dioctyl sulfosuccinate, polyoxyethylene alkylamine, or a fatty acid ester.

- magenta pigment include Pigment Red 122 and Pigment Violet 19.
- yellow pigments include pigment yellow 74, pigment yellow 109, pigment yellow 110, and pigment yellow 128.
- the humectant is preferably a polyhydric alcohol such as glycerin or a water-soluble nitrogen heterocyclic compound such as 2-pyrrolidone or N-methyl-2-pyrrolidone.
- the penetrant is a monoalkyl ether of a polyhydric alcohol, such as diethylene glycol monobutyl ether.
- the ink has a surface tension at 25 ° C. of 20 to 5 before the silane compound undergoes a polycondensation reaction (a state before the silane compound adheres to the recording paper 41).
- O mNZm is set.
- the surface tension of the ink may be set by adjusting the content of the penetrant with respect to the entire ink, and the content of the penetrant is 1 to 50% by mass percentage with respect to the entire ink. Preferably, there is. This means that if the penetrant content is less than 1%, the surface tension of the ink will not fall below 5 OmN / m, while if it exceeds 50%, the solubility of the colorant and silane compound in the solvent will increase. Is worse.
- the surface tension of the solvent before dissolving the coloring material and the silane compound may be set to 20 to 50 mN / m. In this way, if the ink is produced by dissolving the coloring material and the silane compound in this solvent, the surface tension of the ink will be approximately 20 to 50 mN / m.
- fluorine is used as an auxiliary agent for the penetrant.
- a system surfactant may be added.
- the fluorosurfactants include, for example, ammonium salt of perfluoroalkylsulfonic acid, potassium salt of perfluoroalkylsulfonic acid, and potassium salt of perfluoroalkylcarboxylic acid. I prefer to do that.
- the ink for inkjet recording comprises a humectant and a penetrant. And a water-soluble solvent, a colorant, and a hydrolyzable silane compound as a water-soluble substance that undergoes a polycondensation reaction in the absence of water. Since it is set to a relatively low value of 0 to 5 OmN / m, when an image is formed on the recording paper 41 by the recording device A using this ink, after the ink droplets adhere to the recording paper 41, However, the solvent of the ink droplet quickly permeates into the recording paper 41. As a result, the silane compound quickly undergoes a polycondensation reaction, and the polycondensed silane compound rapidly and surely surrounds the coloring material. As a result, a high level of image water resistance can be obtained even immediately after image formation.
- the surface tension of the ink is preferably as low as possible from the viewpoint of promptly penetrating the solvent into the recording paper 41.However, when the surface tension of the ink is smaller than 20 mNZm, the ink is discharged from the nozzle 1 When the ink is ejected from 4, it is difficult to form this ink into droplets, which is not preferable for ink jet recording.
- the ink has an ink viscosity at 25 ° C. of 2 to 10 cP before the silane compound undergoes the condensation polymerization reaction.
- the viscosity of the ink is relatively low, that is, 10 cP or less, the solvent can be more quickly penetrated into the recording paper 41, and the solvent can be promptly introduced into the recording paper 41. From the viewpoint of permeation, the lower the better, the better.
- the viscosity of water is about 1 cP
- the viscosity of ink containing a colorant, a humectant, a penetrant and a silane compound in addition to this water is 2 This is because c P is the lower limit.
- the piezoelectric element 23 in the piezoelectric actuator 21 has a thickness of 8 ⁇ m or less (for example, about 3 / m) as in the recording apparatus A described above, the silane compound reacts by condensation polymerization. It is preferable to set the ink surface tension at 25 ° C. in the previous state to 30 to 4 OmN / m. In other words, when a thick-film piezoelectric element having a thickness of, for example, 10 111 or more is used instead of the piezoelectric element 23, the piezoelectric actuator 21 generated by the thick-film piezoelectric element is pulled back.
- the force force when the piezoelectric actuator 21 returns to its original state
- the surface tension of the ink is relatively low, about 2 OmN / m.
- the ink pushed out from the nozzle 14 can be torn off to form an ink droplet.
- the piezoelectric element 23 is a thin film having a thickness of 8 m or less
- the pullback force of the piezoelectric actuator 21 generated by the piezoelectric element 23 of the thin film is small, so that the surface of the ink If the tension is lower than 3 OmN / m, the ink ejected from the nozzle 14 cannot be torn off and may form ink droplets (especially small ink droplets with an ejection volume of 3p1 or less). I can no longer do it.
- the surface tension of the ink is 30 mN / m or more, even if the piezoelectric element is a thin film, it is possible to reliably form and discharge the ing droplet.
