Background of the invention

The technical field to which the invention relates.

The present invention relates to inks for inkjet printing, which have high resistance to environment gases and give a good image, which prevent the appearance of the metal layer, the so-called bronzing, even when the ink deposited on the print media. The present invention relates also to a method of inkjet printing, ink cartridge, the printer and apparatus for inkjet printing, in each of which the ink is used for inkjet printing.

Related prior art

Method of inkjet printing is a printing method that includes applying small drops of ink on any printed media, such as plain paper and glossy environment to get the image, this method quickly became widespread by reducing its cost and increasing print speed. With the rapid proliferation of digital cameras, in addition to improving the quality of the image obtained in this way, the method became widely accepted as the method of displaying photographic images, comparable with photos on the basis of the halides of silver.

In recent years, the image quality has never before possible improvement due to, for example, extremely strong reduced the th of the size of ink droplets and better color, part of the color ink. Meanwhile, grew requirements for the dye and the ink, so that required more stringent specifications with respect to improving the ability to show color and stability, such as resistance to clogging or the stability of the emission stream.

Compared to the photo on the basis of silver halides method of inkjet printing has problems in relation to, for example, image stability during storage of the obtained printed product. In General, product print obtained using the method of inkjet printing has the worst image stability during storage than the pictures on the basis of the halides of silver, and causes such a problem that the dye on the printed product tends to deteriorate, which causes a change in the color tone of the image and fading of the image when printed product is exposed to light, heat, gas environment, present in the air, or such longer period of time. In particular, the problem of the method of inkjet printing has traditionally been improved resistance to environment gases to the level of pictures based on silver halides. Of yellow, Magenta and cyan, which is the inks used for inkjet ink, the lowest resistance to gases environment has blue. Thus, the improvement in which tasciotti blue ink to the environment gases to a level comparable to the yellow ink or Magenta ink, is an important problem in the method of inkjet printing.

Based dye inkjet ink having a blue color, can be roughly divided into phthalocyaninato basis and triphenylmethanol basis. Typical dyes (C.I.) of the first type include Direct blue 86 and 87, Direct blue 199. Typical dyes (C.I.) of the second type include Acid blue 9.

In General, dye-based phthalocyanine differs in that it has excellent light fastness as compared with the dye-based triphenylmethane. In addition, the dye-based phthalocyanine has a high stability to moisture or heat and has a good svetopronitsaemuyu ability, and therefore, this dye was actively used as a dye for inkjet ink.

However, dye-based phthalocyanine usually has poor stability to the environment gases in the air such as ozone, NOxor SO2), especially ozone. In particular, in the printed product obtained by applying colour on print media having ink absorbing layer containing an inorganic substance such as alumina or silicon, the stability is quite low, so that the fading of the printed product significantly, when the printed product remains in the room for a long time. Were OPI is Ana various compounds to be added to the ink in order to improve the resistance to gases in the environment (see, for example, laid claim to the Japan patent No. H05-171085, laid claim to the Japan patent No. Hll-29729, laid claim to the Japan patent No. H10-130517 posted a request on the Japan patent No. 2000-303009 and posted a request on the Japan patent No. 2002-249677). However, none of these publications in the ink for ink-jet printing was not achieved combinability good tsvetoproba ability and high resistance to gases to the environment.

Dye-based phthalocyanine has another disadvantage, namely a metallic luster due to the high aggregation ability of the dye, the so-called bronzing. When the printed product bronzing occurs, changing the reflectivity of the printed product. In svetoprelomlyayuschaya ability and tone of the image vary markedly, resulting in a noticeable reduction in image quality. It is believed that the bronzing results from the aggregation of the dye on the surface of the print medium due to, for example, high aggregation ability of the dye in the ink and reduce the leakage of the ink inside the print media when the ink deposited on the medium. In particular, the dye in the molecule of which entered the amino group in order to improve the resistance to gases in the environment, or the ink containing the dye with low Rast is aremostly in water, tend to cause a noticeable bronzing.

For example, to improve the resistance to environment gases was proposed to use a special dye-based phthalocyanine (see, for example, JP patent 2942319). The use of a special dye-based phthalocyanine provides resistance to gases in the environment, which is one of the problems of dyes based on phthalocyanine. However, the proposal says nothing about the bronzing, so that the stability of the dye to the bronzing is not clear. In other words, the compatibility of resistance to bronzing and resistance to environment gases have not been received.

Thus, it was necessary to find ink for inkjet printers using dye based on phthalocyanine, which have excellent svetopronitsaemuyu ability, have a high resistance to environment gases and prevent the occurrence of bronzing.

In particular, blue ink generally have poorer resistance to gases environment among the yellow ink, Magenta ink and cyan ink, all of which are actively used as ink for inkjet printing. To solve the problem of stability of blue ink to the environment gases, the present invention is the creation of blue ink, for which, when a printed product obtained by using the blue ink is exposed to the environment having a temperature of 40°C, humidity 55% and the ozone concentration of 2 ppm, 20 hours, the optical density in the reflected light at 50% degree of filling of the printed product is 83% or more from the optical density of the reflected light at 50% degree of filling of the printed product before exposure. Printed product obtained with the use of yellow ink and Magenta ink, all of which are very resistant to the environment gases, it has excellent resistance to gases in the environment in which after the above exposure conditions remains of 83% or higher optical density in the reflected light. Therefore, using blue ink, for which after the above exposure conditions remains of 83% or higher optical density in the reflected light, in combination with the yellow ink and Magenta ink, which both have about the personal resistance to environment gases, it is possible to obtain an image with excellent storage stability.

In General, dye-based phthalocyanine has a higher tendency to aggregation than dyes with other structures (for example, on the basis of triphenylmethane, azo dyes or dyes based on xanthan gum). Strengthening the aggregation ability increases stability.

Meanwhile, the dye with high aggregation ability detects high aggregative ability of the dye in the ink. Therefore, brezinova is s, which leads to the deterioration of the image when it is printed on a printing medium using a dye tends to become more prominent.

On the contrary, when the dye has a substantially low aggregation ability, decreases the stability of the dye (particularly resistance to gases in the environment). Therefore, the printed product obtained by using the ink containing the dye, may be unable to provide image stability when stored at the same level as the yellow ink and Magenta ink, both of which have excellent resistance to gases in the environment.

Thus, when the compound represented by the General formula (I)or its salt is used as a dye, the aggregation ability of the dye should be regulated so that the occurrence of bronzing can be suppressed, and in order to obtain the desired resistance to gases to the environment.

Comparison of compounds represented by the General formula (I)or its salt, which is a dye for use in the ink of the present invention, and dye (C.I. Direct blue 199, Direct blue 86 or the like, which is typical dyes having the same skeleton as the above dye and usually used for ink, shows the following. the first dye molecular weight substituent, which replaces on phthalocyaninato the skeleton, large, and molecular weight of the total dye is also great, so that the efficiency of staining at the same weight % reduced in comparison with the efficiency of the dye. Thus, the concentration of the dye in the ink should be set to be high to get svetopronitsaemuyu ability comparable with ink containing a conventional dye. In particular, the content of the dye (wt.%) is preferably 3.0 mass% or more of the total weight of the ink, in order to get svetopronitsaemuyu ability, comparable to the capacity of the ink containing a conventional dye when the latter is caused by ink on uncoated paper or the like having a low svetopronitsaemuyu ability. The content is preferably 10.0 wt.% or less in order to sufficiently satisfy stability, such as docking.

It should be noted that when the concentration of dye in the ink is high, is the aggregation of the colorant on the print media and, hence, occurrence of bronzing is usually more noticeable. Thus, even if the content (i.e. the concentration of the dye) compounds represented by the General formula (I)or its salt, which is a dye for use in the inilah of the present invention, up to 3.0 wt.% or more of the total weight of the ink, the aggregation ability of the dye should be regulated so that the occurrence of bronzing can be suppressed, and in order to obtain the desired resistance to gases to the environment.

On the basis of previous data obtained by the authors of the present invention conducted intensive studies, paying attention to the aggregative ability of the compounds represented by the General formula (I), or salts thereof. In the result, the inventors have found a method that includes changing the type of the substituent for the dye, which is the compound represented by the General formula (I)or its salt, to regulate the aggregation properties of the dye to provide excellent svetopronitsaemuyu ability to suppress the occurrence of bronzing, and increase resistance to gases to the environment. Thus, the authors have accomplished the present invention.

The measurement of the aggregation properties of the coloring

To measure the aggregation properties of the dye used in the present invention, we use the method of small-angle x-ray scattering.

As described, for example, in "Saishin Colloid Called" (news colloid chemistry) (Kodansha Scientific, Fumio Kitahara and Kunio Furusawa) and in "Hyomen Jotai To Colloid Jotai" (Surface condition and the colloidal state) (Tokyo Called Dozin Co., Ltd., Masayuki Nakagaki), how small the angle x-ray scattering is a approach which was usually used to calculate the distance between colloidal particles in a colloidal solution.

The diagram of the apparatus small-angle x-ray scattering will be described with reference to Fig. 1, which shows the principle of measurement according to the method of small-angle x-ray scattering. The focal spot size of each of the x-rays generated by the x-ray source, is reduced to approximately several millimeters during the passage of x-rays from the first to third slits, and the trial solution is irradiated with x-rays. X-rays, which were irradiated test solution, dispersed particles of the test solution before x-rays will be detected on the exposed plate. Since the scattered x-rays interfere with each other due to the difference of the optical path between them, the value of the distance d between the particles can be determined on the basis of the equation Bragg (the following expression (1)), using the resulting value of θ. When the particles are at equal distances determined in this case, the value of d is considered as the distance from the center of the particle to the center of the neighboring particles.

d=λ/2sinθ(1)

(In the expression (1) λ is the length of any x-rays, d means the distance between particles, and θ denotes the scattering angle.)

In General, when particles in the solution are irregularly peaks in the profile of the scattering angles are missing. In the case of an aqueous dye solution (dye-based phthalocyanine used in the present invention, there is a strong peak having the maximum value in the range of 2θ=0-5°, and it was found that the particles (molecular aggregates)formed by aggregation of the dye on the basis of phthalocyanine, are located with a certain regularity. Fig. 2 shows the profile of the scattering angle at 10% (wt.%) an aqueous solution of the dye-based triphenylmethane, having a structure represented by compound (1) below, and dye-based phthalocyanine having the structure represented by the General formula (I). In Fig. 2 shows that based dyes phthalocyanine specifically, there are peaks of scattering angles, even when they have the same blue color. In other words, several of phthalocyanine molecules aggregate in aqueous dye solution based on phthalocyanine with the formation of molecular aggregates. In addition, the distances between the molecular units have a continuous distribution, which can be represented by a profile of scattering angles.

Connection (1)

Fig. 3 is schematizes the s view of the distances between molecular aggregates of dye based on phthalocyanine. As can be seen in Fig. 3, the radius of certain molecular aggregates of the dye based on phthalocyanine denoted by r1, and the distance between molecular aggregates denoted by d1. Assuming that d1 is always constant, when the structure of the dye based on phthalocyanine remains unchanged, it is considered that the value of d measured by the method of small-angle x-ray scattering, increased from d2 to d3 with increase in the radius of the molecular aggregate formed by dye-based phthalocyanine, from r1 to r2. Thus, the value of d measured in the above manner, is considered as an indicator of the size of the molecular aggregate of the dye based on phthalocyanine, and it is expected that the size of the molecular aggregate formed by the dye molecules, increases with increasing d values.

Studies of the relation between the value of d in the ink containing the dye based on phthalocyanine, and the bronzing phenomenon revealed that in the case of dyes based on phthalocyanine having the same structural formula, bronzing will happen more likely when the value d is greater. Taking into account the fact that the bronzing occurs due to aggregation of the dye molecules on the print carrier, it has been suggested that there is a correlation between the above value of d and the size of the molecular Agra is ATA.

The shape of the peak in the profile of scattering angles indicates the distribution of distances between molecular aggregates, that is, the distribution range of the scattering between molecular aggregates. Considering the above fact that the range of dispersion is a measure of the size of the molecular aggregate, the profile of scattering angles, as expected, indicates the size distribution of molecular aggregates in solution. In other words, assuming that the peak area in the profile of scattering angles gives the sizes of all molecular aggregates in solution, bronzing becomes more likely when the magnitude of d, that is, with increasing frequency of large molecular aggregates. Therefore, it is expected that a reduction in the frequency of large molecular aggregates, which can cause bronzing, will be able to suppress the occurrence of bronzing. However, in the case of the ink containing only a very small molecular aggregates, the stability of ink to the environment gases is reduced, although the bronzing less likely. Accordingly, the sizes of the aggregates of molecules (the absolute value of d) must be properly adjusted in order to suppress the occurrence of bronzing and get resistance to gases to the environment.

Generally, when the size of the dye molecules have a certain frequency of races is the definition, specifies that the threshold visual otsuvstviya, which is the detection limit of the person, equal to 25% of full amount. In view of the foregoing, the value of d at the point in which large molecular aggregates, causing bronzing, up to 25% or less of all units, i.e. the point at which small molecular aggregates, which are unlikely to cause bronzing make up 75% or more of all units, is defined as the value of d75and the value of d75is adjusted to lie in a certain interval, due to what can be obtained ink, which prevent the occurrence of bronzing and have a high resistance to gases to the environment.

Indeed, according to research on the correlation between each

the value of dpeakcalculated from the peak values of 2θ in the profile of the scattering angles, and the above value of d75and the level of manifestation of bronzing, it was found that the value of d75, which takes into account the factor distribution of the sizes of all molecular aggregates, has a stronger correlation with bronzing than the value of dpeak. The baseline for determining the values of 2θ carried out in the range of 0.5-5°.

In view of the foregoing, the authors of the present invention conducted the following experiment using the connect is s, obtained by changing the number, type and positions of substitution of substituents in the compound represented by the General formula (I)or its salt, which is a dye based on phthalocyanine, i.e. dye-controlled aggregation ability. Preparing the ink containing the dye, and measured the profile of the scattering angles ink to calculate the values of d75. Then, based on the obtained values of d75each dye was evaluated on the aggregation ability. In the result, it was confirmed that the ink have a value of d756,50 nm or more and 7.10 nm or less, they effectively suppress the occurrence of bronzing and have a high resistance to gases to the environment. This result also confirms that when the ink have a value of d756,70 nm or more and 7.10 nm or less, the ink is particularly effectively suppress the occurrence of bronzing and have a high resistance to environment gases, namely in the case when the aggregation ability of the compounds represented by the General formula (I)or its salt as a dye is adjusted to a value of d75ink containing the dye was included in the above range, it is found that the ink suppress the occurrence of bronzing and have high resistance to gases in the environment, even if the concentration of the dye selected is high, to get a good svetoprestavlenie.

To measure the value of d way small-angle x-ray scattering, the density of molecules in the solution should be kept constant. Therefore, the value of d is preferably measured using ink from remaining constant concentration of dye in it. In the present invention, the profile of scattering angles was measured using an ink prepared so that the content of the dye (wt.%) was 3.0 wt.% of the total weight of the ink. When the content of the colorant in the ink exceeded 3.0 wt.%, the ink was diluted with pure water to obtain a concentration of the dye to 3.0 wt.%, and he measured the profile of the scattering angles of the diluted ink. What ink are the content of the dye to 3.0 wt.%, checked on the basis that the optical density measured after dilution of ink in 1000 times with pure water, is in the range from 1.05 to 1.15.

The conditions in which measure optical density, following.

The above-described aggregation ability of the dye cor is elerhet also with a wavelength of maximum absorption (λmax) in the absorption spectrum. Ink having a stronger tendency to aggregation of the molecules (the larger the value of d75), are usually less than λmax. Therefore, the aggregation ability of the dye can be evaluated by λmax, correlated with the value of d75. In this case it was found that the ink is effectively suppress the occurrence of bronzing and have a high resistance to environment gases, when λmax in the ink, diluted 2000 times with clean water, is 612,0 nm or more and 616,0 nm or less. It was also found that the ink is particularly effectively suppress the occurrence of bronzing and have a high resistance to environment gases, when λmax is 612,0 nm or more and 614,0 nm or less. In other words, when the aggregative ability of the compounds represented by the General formula (I)or its salt, a dye is adjusted to λmax ink containing the dye was included in the above range, it was found that the ink suppress the occurrence of bronzing and have a high resistance to environment gases, even when the concentration of the dye is set high to get a good svetoprestavlenie. The conditions under which the measured wavelength of maximum absorption, the same as the above-described conditions under which the measured optical density.

It is known that the dye on what I use in this invention is less prone to aggregation, when he has fewer unsubstituted sulfamoyl groups and more substituted sulfamoyl groups or sulfonic groups. In particular, in the case where the dye satisfies the requirement for values of d75in the present invention, the dye preferably contains a compound in which the number of substituents l≥1 in the compound represented by the General formula (I)or its salt or the compound represented by the General formula (II)or its salt, as the aggregation of the dye can be suppressed.

The method is applicable to any of the so-called methods of pulse type and a continuous type. In particular, for a pulse-type method is effective for the following reasons. At least one control signal, which corresponds to printing information and causes a rapid temperature rise exceeding the boiling germ, served on the electrothermal Converter, placed in accordance with the sheet or channel of a liquid holding liquid (ink)to thereby cause the electrothermal transducer POPs the AMB thermal energy. Then called thermal effect on the surface of the printhead to generate film boiling. As a result, the liquid (ink) can be formed an air bubble, which is in one-to-one correspondence with the control signal. The growth and contraction of the air bubble causes the liquid (ink) to spill through the opening for ejection, thereby creating at least one drop. The control signal preferably has the form of a pulse, because the growth and contraction of the air bubble can be effected instantly and adequately and, therefore, the liquid (ink) can be discarded with excellent reactivity.
