Description
Technical field
The ink-jet of image that the present invention relates to provide excellent moisture resistance with yellow ink, ink-jet with thin ink, ink set, ink jet recording method, print cartridge, record cell and ink-jet recording device.
Background technology
Ink jet recording method is to form the record images method by apply little ink droplet on recording mediums such as common paper and glossy media, along with cheapization of its price, the raising of writing speed, promptly popularizes development.In addition, except the continuous high image qualityization of its document image, along with popularizing rapidly of digital camera, as the positive widespread use of output intent of the photograph image that is equal to mutually with the silver salt photo.
In recent years, in ink jet recording method, requiring the keeping quality of image.Particularly from the conservatory viewpoint of image, be important factor as the wet fastness of the picture steadiness in the high environment of humidity, studied the ink of the image that excellent moisture resistance is provided.For example proposed the color of same system and the ink that the deep or light different central thin ink of ink contains the wetting ability low volatile organic solvent, wherein said wetting ability low volatile organic solvent hybrid vapor is that the wetting ability low volatile organic solvent that following wetting ability low volatile organic solvent of 1Pa and vapour pressure are 1～10Pa makes (for example opening the 2000-319560 communique referring to the Japanese Patent spy).
On the other hand, proposed a kind of technology of new synthetic colorant, this colorant wet fastness, photostabilization, water tolerance excellence are suitable for ink-vapor recording, and color harmony visibility good (for example opening the 2003-321627 communique referring to the Japanese Patent spy).
Summary of the invention
The inventor is through further investigation, even found that the ink that the image of excellent moisture resistance is provided when using a kind of ink to form image, be used in combination at formation secondary look and tertiary colo(u)r(s) etc. under the situation of other ink formation image, owing to constitute the influence of composition of the composition of other ink, have the situation of the wet fastness variation of gained image.
Particularly in recent years, when making the record thing of photo image quality, main in order to improve the gray scale expression power of image, just being extensive use of colorant concentration is the so-called thin ink of 0.1 quality %～2.0 quality %.The inventor has confirmed thin ink is being used in combination with other ink under the situation that forms image, and the composition of thin ink exerts an influence to the wet fastness of image.
Therefore thin ink is because colorant concentration is low, ink viscosity is also low, and in order to make the ink with the equal viscosity of other ink of being used in combination with thin ink, most of thin inks contain water-miscible organic solvent in a large number in it is formed.In addition, thin ink is low owing to colorant concentration, therefore, and the tendency that exists thin ink that the applied amount of recording medium is Duoed than the applied amount of thick ink water.Thus, can think that the wet fastness variation of water-miscible organic solvent and gained image has certain relation.
In the record thing of making in that recording medium is applied ink, the water-miscible organic solvent in the ink is in the state of infiltration.That is, in the water-miscible organic solvent in the described record thing, the ratio of forming from the water-miscible organic solvent of thin ink becomes big.Therefore, under the situation of only using colorant concentration above the thick ink water formation image of 2.0 quality % is no problem, yet under the situation that the thin ink that with colorant concentration is 0.1 quality %～2.0 quality % uses, but found the new problem of the wet fastness meeting variation of image.As mentioned above, the wet fastness of image is because of the solvent effect variation in the record thing.Therefore, can think that the wet fastness of image is improved by reducing the content of the water-miscible organic solvent in the ink.
But the inventor found that through further investigation the content of the water-miscible organic solvent in the ink is not merely related with the wet fastness of image.So further the wet fastness that found that image of research is except relevant with the volatility (rate of evaporation) of the water-miscible organic solvent that comprised in the ink, and is also closely related with the water absorbability (rate of moisture absorption) of water-miscible organic solvent.In other words, in order to improve the wet fastness of image, it is inadequate only designing ink according to the viewpoint of the volatility (rate of evaporation) of the water-miscible organic solvent in the ink, must consider that also the water absorbability (rate of moisture absorption) of water-miscible organic solvent designs ink.
Simultaneously, use the high water-miscible organic solvent of volatility to design under the situation of ink, also must satisfy the reliability of starting ink for inkjet such as ejection stability.
On the other hand, in recent years, conservatory requirement uprises to image, and the wet fastness of image is also required stricter level.Therefore, require to use to have good color tone (form and aspect), visibility and photostabilization and the also excellent colorant of water tolerance, and require to bring into play this performance to greatest extent, reach higher level.
Thereby, the object of the present invention is to provide a kind of ink-jet yellow ink, its provide have good color tone, the image of excellent moisture resistance.

Embodiment
Below, enumerate preferred embodiment illustrating in greater detail the present invention.
In addition, among the present invention, compound is under the situation of salt, and salt is dissociated into ion and exists in ink, but for the purpose of convenient, is expressed as " containing salt ".
＜ink 〉
Below, grade for the one-tenth that constitutes ink of the present invention, be described in detail.
(water-miscible organic solvent and water)
Employed water-miscible organic solvent must be in the thin ink that yellow ink of the present invention uses: with respect to the total content (quality %) of ink-jet with water-miscible organic solvent in the thin ink, the total content (quality %) of water-miscible organic solvent that rate of evaporation X (quality %) and rate of moisture absorption Y (quality %) satisfy the relation of following formula (1) is more than the 50 quality %.
Y≤2.8X+10 formula (1)
Following the trying to achieve of rate of evaporation X (quality %) among the present invention: the ware of the 5g water-miscible organic solvent being put into external diameter 31mm, high 15mm, after leaving standstill 192 hours under the environment of 60 ℃ of temperature, humidity 10%, measure the quality of water-miscible organic solvent once more, try to achieve rate of evaporation X value from the quality of the water-miscible organic solvent that reduces.In addition, following the trying to achieve of rate of moisture absorption Y (quality %): the ware of the 5g water-miscible organic solvent being put into external diameter 31mm, high 15mm, after leaving standstill 192 hours under the environment of 30 ℃ of temperature, humidity 80%, measure the quality of water-miscible organic solvent once more, try to achieve rate of moisture absorption Y value from the quality of the water-miscible organic solvent that increases.Fig. 1 is the graphic representation of the relation of the rate of evaporation of each water-miscible organic solvent of calculating by aforesaid method of expression and rate of moisture absorption.
The ink that modulation contains above-mentioned water-soluble solvent carries out following experiment.The modulation pattern ink, it contains 3 quality % is water as directly yellow 132,20 each water-miscible organic solvent of quality % of the C.I. of colorant, 0.5 quality % as Acetylenol E-100 (manufacturing of Off ア イ Application ケ ミ カ Le is ground in the river), the remainder of tensio-active agent.Again, separate, modulate the no colorant ink of replacing colorant with water separately with this model ink.Make the record thing, it is formed with resulting model ink and no colorant ink and changes the overlapping and formation image of duty with 0～100%duty respectively.In addition, in the manufacturing of record thing, use PIXUS950i (Canon's manufacturing) as ink-jet printer, use professional printing paper (SP-101; Canon makes) as recording medium.
The resulting records thing was placed 48 hours down at the environment (ambient temperature and moisture) of 25 ℃ of temperature, humidity 60%, water-miscible organic solvent and water are evaporated from recording medium.Be less than in storage period under 48 hours the situation, the amount that remains in water-miscible organic solvent in the recording medium and water is fixing, thereby is considered to the evaluation result instability.Use spectrophotometer (trade(brand)name: Spectorolino; Gretag Macbeth manufacturing) environment that is determined at 25 ℃ of temperature, humidity 60% descends the tone of placement after 48 hours, obtains La
*b
*Value.Then, place more than 96 hours down, make the water-miscible organic solvent migration at the environment (hot and humid) of 30 ℃ of temperature, humidity 80%.By making storage period is more than 96 hours, compares the migrate attribute of water-miscible organic solvent easily.Be 168 hours current storage period.Use and the above-mentioned same tone of spectrophotometric determination after placing 168 hours under the environment of 30 ℃ of temperature, humidity 80%, obtain the La after water-miscible organic solvent moves
*b
*Value.Obtain the maximum value of aberration (Δ E) from resulting result.
There is correlationship as can be seen between them from the rate of evaporation of above-mentioned experimental result and each water-miscible organic solvent and the relation of rate of moisture absorption.
Migration is meant following phenomenon: wait in the environment hot and humid, because the ink moisture absorption in the recording medium, the colorant that is contained in the ink moves in recording medium, causes the tonal variation of record thing and the China ink of spreading and sinking in, the image variation.Among the present invention, when taking place, the colorant migration thinks that the colorant wet fastness is poor in the record thing.Thereby, can think that the aberration that produces owing to environment is more little, the migrate attribute of this water-miscible organic solvent is good more.Migrate attribute is good, be wet fastness good water-miscible organic solvent has easy evaporation, be difficult for the feature of moisture absorption.In other words, the good water-miscible organic solvent of migrate attribute, the maximum value of its aberration (Δ E) is more little.Based on the maximum value of this Δ E, distinguish the migrate attribute of water-miscible organic solvent by following standard.
A: the maximum value of Δ E≤5.5
C: the maximum value of Δ E＞5.5
The maximum value of Δ E is under the situation below 5.5, also can not move caused tonal variation under hot and humid environment, is preferred as image.With respect to this, the maximum value of Δ E greater than 5.5 situation under, it is remarkable to move the tonal variation that is caused under hot and humid environment, produces image deterioration.The relational expression that migrate attribute by finding out each water-miscible organic solvent based on this standard and the relation between rate of evaporation and the rate of moisture absorption obtain is above-mentioned formula (1).That is, among Fig. 1, under the situation of the water-miscible organic solvent on the straight line right side of Y=2.8X+10, aberration (Δ E) is below 5.5, and under the situation of the water-miscible organic solvent in the straight line left side of Y=2.8X+10, aberration (Δ E) is greater than 5.5.
In addition, generally when seeking to improve wet fastness, also can use the low solvent (poor solvent) of solubleness of dyestuff.But, in dyestuff used in the present invention, do not find out migration and the dependency of dyestuff to the solubleness of water-miscible organic solvent.That is, among the present invention in the employed dyestuff raising of wet fastness be not to be the solubleness of water-miscible organic solvent to be arranged by dyestuff, but arrange by the rate of evaporation of the water-miscible organic solvent that ink contained and rate of moisture absorption.
Satisfy the object lesson of water-miscible organic solvent of the relation of following formula (1), can list ethylene glycol, Diethylene Glycol, 2-Pyrrolidone, 1,5-pentanediol, 1,6-hexylene glycol, ethylidene-urea.Wherein preferred especially ethylidene-urea.In addition, from improving the viewpoint of characteristics of inkjet such as reliability, special preferably combination is used ethylidene-urea and Diethylene Glycol and 2-Pyrrolidone.In addition, if satisfy the water-miscible organic solvent of the relation of above-mentioned formula (1), then also can use not to be recorded in top water-miscible organic solvent.In addition, in Fig. 1, ethylene glycol satisfies Y≤2.8X+10, but because the value of rate of evaporation is big, does not therefore put down in writing ethylene glycol in the drawings.
In addition, in the thin ink of the present invention,, also can in can obtaining adding effect that they bring and the scope of not damaging target effect of the present invention, use even glycerine, urea etc. do not satisfy the water-miscible organic solvent of the relation of following formula (1).But in order fully to obtain effect of the present invention, with respect to the total content (quality %) of the water-miscible organic solvent that thin ink contained, the content (quality %) of water-miscible organic solvent that satisfies the relation of following formula (1) is necessary for more than the 50 quality %.
In addition, in the yellow ink of the present invention, the content (quality %) of water-miscible organic solvent that also preferably satisfies the relation of following formula (1) is more than the 50 quality % with respect to the total content (quality %) of the water-miscible organic solvent that yellow ink contained.
In addition, the total content (quality %) of water-miscible organic solvent is preferably 10 quality %～50 quality % with respect to the ink total mass in yellow ink of the present invention and the thin ink.The total content of water-miscible organic solvent (quality %) is lower than the situation of 10 quality % or is higher than under the situation of 50 quality %, and characteristics of inkjet such as reliability can variation.
In addition, water preferably uses deionized water (ion exchanged water).The content of water is preferably 10 quality %～90 quality % with respect to the ink total mass.
