Description

  The present invention relates to a liquid ejecting liquid in which a fragrance component is stably dissolved and dispersed, a liquid ejecting apparatus, and a liquid ejecting head in order to impart an aroma effect to a printed matter and maintain the aroma effect.

  Unlike recent printing methods that require the preparation of printing plates, liquid jet recording (inkjet recording) methods can print various patterns with a single machine, so they can be used in a wide range of fields, such as packing materials, posters, and car body wrapping. It is possible to use in.

  Conventionally, liquid jet recording methods can be broadly classified into two types, a continuous type and an on-demand type. In the continuous type, for example, liquid ejecting liquid (ink) is ejected in the form of particles, and an electric field is formed in the traveling path of the charged liquid ejecting liquid particles, thereby deflecting the liquid ejecting liquid particles. Can be recorded on the object. In the on-demand type, for example, liquid ejecting liquid is ejected from an ejection hole (nozzle) of a liquid ejecting recording head (inkjet head) according to an image, and printing is performed on a recording medium such as paper, film, or fabric. What to do.

  The advantages of these liquid jet recordings are that the recording method prints the recording medium by directly blowing ink, and in addition to the simple process, there is no noise because it is not an impact method, and colorization Excellent features such as easy printing, high-speed recording, low running cost because plain paper can be used, and high-resolution recording to discharge fine liquid droplets. (Patent Document 1).

  In addition, by adding a resin to the liquid jetting liquid, an attempt to cover the colorant with a resin film accompanying the volatilization of the liquid jetting liquid solvent (Patent Document 2), light irradiation after printing by adding a photocurable resin Attempts have been made to improve the durability such as weather resistance, scratch resistance, solvent resistance, etc., such as attempts to accelerate the curing of liquid jetting liquids (Patent Document 3).

  On the other hand, with the wide variety of uses of printed materials, there has recently been a need to give the printed materials special properties such as generating a fragrance from the printed materials. In order to meet these needs, devices such as adding a scent component to ink have been devised, but the fields of application are mainly screen printing and offset printing. In the field of ink-jets, there has been proposed one in which a fragrance component is added to the ink itself (Patent Documents 4 and 5), but it has not yet been replaced by screen printing or offset printing.

  For example, when perfume oil is added directly to the ink, the solvent evaporates when the ink applied on the recording medium is dried, and at the same time, the perfume oil evaporates to weaken the aroma generated from the printed matter. Since the perfume oil remaining after drying is also exposed, it tends to evaporate in the atmosphere, and there are many problems such as a very short period during which an aroma can be imparted to the printed matter.

  Therefore, in the field of screen printing and offset printing, the perfume oil is enclosed in hollow particles and added to the ink, whereby evaporation of the perfume oil during drying of the ink applied on the recording medium can be suppressed and the perfume oil is exposed. Since it is not applied in the applied state, the fragrance is gradually released from the hollow particles (sustained release action), and the period during which the fragrance action can be imparted to the printed matter can be greatly extended (Patent Document 6).

  However, in the techniques described in Patent Documents 4 and 5, there are almost no specific physical properties and compositions of the liquid jetting liquid to which the fragrance component is added. There are many unknowns about the effects on physical properties and stability, and further investigation is required for implementation.

  In particular, when the liquid jetting liquids described in Patent Documents 4 and 5 are used, the viscosity of the liquid jetting liquid increases in a low temperature environment and is not jetted from the jet holes, and the fragrance component is separated. It tends to cause problems such as When the fragrance component is separated, the fragrance component is likely to be present as oil droplets in the liquid jetting liquid, forming an emulsion state in a pseudo manner, and the fluidity of the liquid jetting liquid is greatly changed. End up. On the other hand, in a high-temperature environment, the viscosity of the liquid jet liquid is too low, and problems such as splashing during printing are expected.

  Moreover, since the technique described in Patent Document 6 is added to the ink in a state in which the perfume oil is sealed in the hollow particles, ensuring the dispersibility becomes a major issue. Conventionally known dispersants can be used to disperse the hollow particles. However, it is generally difficult to ensure the dispersibility of the hollow particles in the ink jet field using a low-viscosity liquid, and the technique of Patent Document 6 is directly applied to the ink jet field. I can't do it.

  On the other hand, if the particle size of the hollow particles is too small, the amount of perfume oil that can be included is inevitably reduced, and the fragrance produced from the printed matter after being applied on the recording medium becomes weak, or it may not be felt at all. End up. Furthermore, the wall material of hollow particles that has been widely used to encapsulate the fragrance component in the past is an organic material, and depending on the type of solvent and fragrance component used in the ink, the organic material that is the wall material of the hollow particle is eluted, Since the desired function may not be provided due to collapse, the degree of freedom in designing the ink is inevitably narrowed.

  Specifically, it is necessary to produce hollow particles with a wall material that does not dissolve in an ink solvent or a fragrance component as a liquid jetting liquid that can form an image, and can contain a perfume oil amount that can impart an aroma effect to a printed matter, and from a nozzle It is also necessary to stably disperse hollow particles having a particle size that can be ejected into the ink. It is necessary to select a hollow particle capable of satisfying these conditions and to design an ink composition that can ensure dispersion stability.

  In order to overcome the above problems, the present invention imparts a fragrance effect to a printed matter by adding particles, which have better dispersion stability than conventional hollow particles and can impregnate or contain a fragrance component, to a liquid jetting liquid. In addition, an object of the present invention is to provide a liquid jet liquid, a liquid jet recording head, and a liquid jet recording apparatus that can maintain the aroma action.

In order to solve the above problems, the liquid jetting liquid of the present invention comprises a shear thinning agent, a solvent and a fragrance component, and has a viscosity at a temperature of 25 ° C. and a shear rate of 10,000 s ⁻¹ of 3 to 30 mPa · The configuration of s is adopted.

By containing a shear thinning agent, shear thinning is exhibited. Here, “shear thinning” means that the viscosity is high in a stationary state, but the viscosity is lowered by applying external pressure such as vibration and shear. Therefore, the viscosity is low when discharging from the liquid jet head and shows good discharge performance, but when left standing, such as during storage, the application of pressure is canceled and the viscosity increases, so the content of the liquid jet liquid It is possible to suppress sedimentation and separation of substances. Further, in order to fly the liquid jetting liquid, it is sufficient that it is 3 to 30 mPa · s when the shear rate applied at the jetting hole is 10000 s ^−1. Absent. By adding the fragrance component to the liquid jet liquid having such characteristics, it is possible to suppress the separation of the fragrance component from the liquid jet liquid over time, and the mixing and dispersion of the liquid jet liquid and the fragrance component are prevented. Stabilization can be achieved.

In addition, a configuration in which the shear thinning agent according to the present invention is an inorganic particle, a configuration in which a fragrance component is contained inside the inorganic particle, and a configuration in which the inorganic particle is in a tube shape or a hollow particle shape. Is adopted.
Inorganic particles are difficult to dissolve in liquid jetting liquids and fragrance components mainly composed of alcohol, ether, and esters, and by adopting the above-mentioned inorganic particles, stable chemical and physical properties can be obtained over time. Can be maintained.

Further, a configuration is adopted in which the inorganic particles are a substance selected from silicon, magnesium, carbon, titanium, aluminum, zirconium and their compounds.
Silicon, magnesium, carbon, titanium, aluminum, zirconium and these compounds are relatively versatile and inexpensive, and in addition to impregnating or encapsulating perfume ingredients, It also has the feature that it can be easily processed into a tube shape. Furthermore, since the material is inorganic, it is difficult to dissolve in a fragrance component, which is an organic solvent mainly containing alcohol, ether, or ester, or a solvent used in a liquid jetting liquid, and the options for the fragrance component to be impregnated or included are expanded. Can do.

Further, a configuration is adopted in which the inorganic particles are any one of SiO ₂ · nH ₂ O, Si (OH) ₂ , magnesium oxide, and magnesium carbonate.
The liquid jet recording head using the liquid jet liquid according to the present invention includes an actuator plate having a channel formed by a piezoelectric element, a liquid chamber plate having a liquid chamber for supplying a liquid to the channel, and a recording target. And a nozzle plate on which nozzles for discharging a liquid jet liquid toward the medium are formed.
According to this configuration, the liquid ejecting liquid according to the present invention can be ejected onto the recording medium using the liquid ejecting recording head, and desired operations such as printing and recording can be performed.

A liquid jet recording apparatus having a liquid jet head according to the present invention includes a pair of transport means for transporting a recording medium, a liquid supply means for supplying a liquid jet liquid to the liquid jet head, and a liquid jet head. Scanning means for scanning in a direction substantially perpendicular to the conveyance direction of the recording medium.
According to this configuration, the liquid jet head according to the present invention can be mounted on the liquid jet recording apparatus. By adopting this configuration, it is possible to provide means for supplying the liquid ejecting liquid, and continuously eject the liquid ejecting liquid onto the recording medium to perform desired operations such as printing and recording.

By containing a shear thinning agent, shear thinning is exhibited. Here, “shear thinning” means that the viscosity is high in a stationary state, but the viscosity is lowered by applying external pressure such as vibration and shear. Therefore, the viscosity is low when discharging from the liquid jet head and shows good discharge performance, but when left standing, such as during storage, the application of pressure is canceled and the viscosity increases, so the content of the liquid jet liquid It is possible to suppress sedimentation and separation of substances. Further, in order to fly the liquid jetting liquid, it is sufficient that it is 3 to 30 mPa · s when the shear rate applied at the jetting hole is 10000 s ^−1. Absent. On the other hand, when the viscosity at 10000 s ⁻¹ is less than 3 mPa · s, splashing is likely to occur, and it becomes difficult to ensure image quality. On the other hand, if the viscosity at 10,000 s ⁻¹ exceeds 30 mPa · s, the flying speed is likely to be abnormal.

  Also, by impregnating or encapsulating the fragrance component in an inorganic material and adding it to the liquid jetting liquid, it is dissolved in the solvent used in the fragrance ingredient or liquid jetting liquid, which is an organic solvent mainly containing alcohol, ether, or ester. It is difficult to expand the options of the perfume ingredients to be impregnated or encapsulated. In particular, by selecting silicon, magnesium, carbon, titanium, aluminum, zirconium, and their compounds, which have relatively high versatility, the manufacturing cost can be kept low, and in addition, impregnation or inclusion of fragrance components The advantage of being easily processed into a porous, hollow or tube shape can also be obtained.

  Furthermore, it is widely known that many inorganic substances are electrically attracted in a solvent and apparently form a lattice structure, that is, impregnated with a fragrance without adding a separate shear thinning agent, Alternatively, by adding an encapsulated inorganic substance, shear thinning can be imparted to the liquid jetting liquid.

It is a figure which shows the containing component and viscosity of the Example of this invention. It is a figure which shows evaluation of the Example and comparative example of this invention.

The viscosity at a temperature of 25 ° C. and a shear rate of 10,000 s ⁻¹ was measured using a rheometer MCR-301 manufactured by Anton Paar.

Hereinafter, the present invention will be described in more detail with reference to specific examples. However, the present invention is not limited to the following examples.
Numbers are shown in FIG. 1 only in the portions containing each component in the examples. In FIG. 1, the location indicated by-(hyphen) indicates that the component is not contained. The unit of the numbers in the examples is “parts by weight”.

Since all of Examples 1 to 3 and Comparative Examples 1 to 4 are water-based inks, a larger amount of water was used as a solvent than the other solvents in each example. The other solvent contains hexyl acetate only in Examples 2 and 3, and only Comparative Example 1 does not contain 2-pyrrolidone and 3-methyl-2-oxazolidinone.
As the fixing resin, Joncrill 711 was used in each example. The colorant in each example was a black colorant of Eisenspiron Black. Of course, the embodiments are applicable to colorants of other color systems. Further, as the dispersant, polyoxyethylene sorbitan monococonut oil fatty acid ester was used in each example.

Hereinafter, particularly in each example, the inorganic particles (hollow particles), the microcapsules, and the fragrance component are characterized and blended as shown in FIG.
Inorganic particles (hollow particles) are blended in Examples 1 to 3 in three to one or two of magtubes, carbon nanotubes, and LINUX, but not in Comparative Examples 1 to 4, respectively. In addition, all three types of inorganic particles (hollow particles) can be used in the examples.

Next, only Example 1 was blended with Kelzan AR, which is a shear thinning agent that is not inorganic particles (hollow particles), and only Comparative Example 4 was blended with microcapsules made of gelatin.
Moreover, the fragrance | flavor component mix | blended 1 type or 2 types from 4 types, Jasmine absolute, lemongrass essential oil, aldehyde C-8, and coumarin in Example 1-3. Moreover, the fragrance | flavor component was not mix | blended in the comparative example 1, but was made to mix | blend 1 type each in 4 types mentioned above in the comparative examples 2-4.

The viscosities of Examples 1 to 3 were 3 to 30 mPa · s at a temperature of 25 ° C. and a shear rate of 10,000 s ⁻¹ , and the dispersion stability of the fragrance component satisfied the desired performance. On the other hand, the viscosities of Comparative Examples 1, 2, and 4 are outside the range of 3 to 30 mPa · s at a temperature of 25 ° C. and a shear rate of 10,000 s ⁻¹ . In Comparative Example 3, the viscosity is within a range of 3 to 30 mPa · s at a temperature of 25 ° C. and a shear rate of 10,000 s ⁻¹ , but no shear thinning agent is added, and the fragrance is inorganic particles (hollow particles). Therefore, dispersion stability could not be imparted, the liquid jetting liquid and the fragrance component were separated in the tank, and no scent was imparted to the liquid jetting liquid ejected from the ejection holes.

  As a result of blending as described above, evaluation as shown in FIG. 2 was performed. The printing environment to be evaluated is that the liquid jet liquid obtained in Examples 1 to 3 and Comparative Examples 1 to 4 is printed on one surface of a PVC film with a liquid jet recording apparatus (360 dpi, drive frequency 8 kHz, number of nozzles 508). did.

(Fragrance)
The liquid jetting liquids of Examples 1 to 3 and Comparative Examples 1 to 4 were solid-printed on the PVC film, and after being left for 30 minutes, the aromas of the printed materials were compared.
○: With fragrance ×: Without fragrance (persistence of fragrance)
The liquid jetting liquids of Examples 1 to 3 and Comparative Examples 1 to 4 were solid-printed on a PVC film, and allowed to stand for 10 days, and then the aromas of the printed materials were compared.
○: with fragrance ×: without fragrance (dispersion stability)
The liquid jetting liquids of Examples 1 to 3 and Comparative Examples 1 to 4 were sealed in a transparent glass bottle, and it was confirmed whether or not the contents were separated when left at 50 ° C. for 3 months.
○: No separation ×: Separation (perfume oil impregnated material / elution of inclusion)
After the liquid jetting liquids of Examples 1 to 3 and Comparative Examples 1 to 4 were sealed in a transparent glass bottle and allowed to stand at 50 ° C. for 3 months, the particle size distribution measurement results before and after aging were compared and the impregnating material / encapsulating material The change in particle size was confirmed.
○: Change rate is 20% or less ×: Change rate is greater than 20% In Examples 1 to 3, the fragrance is worthy of giving a fragrance, and the fragrance is sustained. It can be said that it is an excellent liquid jetting liquid capable of stably dissolving and dispersing components.

  On the other hand, Comparative Examples 1, 2, and 4 cannot be discharged. “Discharge not possible” indicates a state where ink droplets are not separated from the nozzle holes and do not fly. Therefore, the items of “fragrance” and “fragrance persistence” in Comparative Examples 1, 2, and 4 could not be evaluated. Some liquid ejecting liquids cannot be ejected in this way depending on the contained components, but if they cannot be ejected, the performance of the liquid ejecting liquid cannot be evaluated originally. However, since the evaluation item of “dispersion stability” can be evaluated in an environment in which ejection is not performed, Comparative Examples 1, 2, and 4 are described in FIG. 2 by evaluating “dispersion stability”. In Comparative Example 4, since the fragrance was added by being included in the inorganic particles (hollow particles), the evaluation of “solubility of perfume oil impregnated material / encapsulating material” was also performed.

  In addition, in the comparative example 3, it becomes an evaluation result with * as shown in FIG. 2, and is not the content along the content of this invention. “X” indicates a state in which an ink droplet is ejected from the nozzle hole, but a desired print result is not obtained. Further, as in Comparative Example 4, in the case of a microcapsule using an organic material for the wall material, in addition to the solubility in the perfume component to be included, the solubility in the solvent used in the liquid jetting liquid to be dispersed is not considered. In other words, the composition of the liquid ejecting liquid is not limited, and the desired performance cannot be imparted to the liquid ejecting liquid.

  These liquid ejecting liquids are used by being ejected from the liquid ejecting head. The configuration of the liquid ejecting head includes an actuator plate in which a channel is formed by a piezoelectric element, a liquid chamber plate in which a liquid chamber for supplying liquid to the channel is formed, and ejecting the liquid ejecting liquid toward a recording medium. In general, there is no particular limitation as long as the liquid jetting liquid according to the present invention can be used.

  Furthermore, the liquid ejecting head described above is used in a liquid ejecting apparatus. The configuration of the liquid ejecting apparatus includes a pair of transporting units that transport the recording medium, a liquid supply unit that supplies liquid ejecting liquid to the liquid ejecting head, and the liquid ejecting head substantially orthogonal to the transporting direction of the recording medium. In general, there is no particular limitation as long as the liquid ejecting liquid according to the present invention can be used.
