The present invention mainly relates to a recording liquid for use in an inkjet recording system. Non-impact recording methods have the advantage of generating little noise during recording, and have been actively researched recently. Among these, the inkjet recording method, which enables high-speed recording and can record on so-called plain paper without the need for special fixing processing, is an extremely powerful recording method. Some have been devised, improved and commercialized, and others are still being worked on to put them into practical use. This type of inkjet recording method involves flying droplets of recording liquid called ink.
Recording is performed by attaching this to a recording material. The basic components of such a recording liquid include a recording agent (dye or pigment is used) and a liquid medium for dissolving or dispersing it (water or various organic solvents or a mixture thereof is used), and if necessary, Various additives are added. There are various types of such recording methods depending on the method of generating droplets and the method of controlling the flying direction of the droplets. An example is shown in FIG. That is, the apparatus shown in FIG. 1 applies a recording signal to a recording head section having a piezo vibrator, and performs recording by generating droplets of recording liquid in response to the signal. In FIG. 1, reference numeral 1 denotes a recording head, which has a piezo vibrator 2a, a diaphragm 2b, an inlet 3 for recording liquid, a liquid chamber 4 in the head, and an ejection port (ejection orifice) 5. A recording liquid 7 stored in a storage tank 6 is introduced into the liquid chamber 4 through a supply pipe 8 .
Incidentally, an intermediate treatment means 9 such as a pump or a filter may be provided in the middle of the supply pipe 8 depending on the case. A signal converted from the recording signal S into a pulse by a signal processing means (for example, a pulse converter) 10 is applied to the piezo vibrator 2a, and the pressure changes in the recording liquid in the liquid chamber 4 in accordance with the signal. occurs. As a result, the recording liquid 7 is discharged from the discharge orifice 5 in the form of droplets 11, and recording is performed on the surface of the recording material 12. In addition to the above devices, various types of devices are known. For example, as shown in FIG. 2, as a modification of FIG. There is an apparatus in which a piezo vibrator is installed (the mechanism of droplet generation in this apparatus is essentially the same as the apparatus shown in FIG. 1). Also, a device that continuously generates charged droplets and uses a portion of the droplets for recording. Alternatively, there is also known an apparatus that applies thermal energy corresponding to a recording signal to the recording liquid in the chamber of a recording head and generates droplets using the energy. An example thereof is shown in FIG. 3-a, FIG. 3-b, and FIG. 4. The head 13 is made of glass, ceramic, plastic plate, etc. having grooves 14 through which ink passes, and a heat generating head 15 used for thermal recording (a thin film head is shown in the figure, but is not limited to this). Obtained by gluing. Heat generating head 1
5 is made up of a protective film 16 made of silicon oxide or the like, aluminum electrodes 17-1, 17-2, a resistor layer 18 made of nichrome or the like, a heat storage layer 19, and a substrate 20 with good heat dissipation properties such as alumina. It's on. The ink 21 has reached the discharge orifice 22 and forms a meniscus 23 due to the pressure P. Now, when an electric signal is applied to the electrodes 17-1 and 17-2, the area indicated by n of the heating head 15 suddenly generates heat, bubbles are generated in the ink 21 in contact with this area, and the pressure causes the meniscus 23 to rise. protrudes, and the ink 21 is ejected from the orifice 22 into a recording droplet 2.
4 and flies toward the recording material 25. Fourth
The figure shows an external view of a multi-head in which a large number of heads shown in Figure 3-a are arranged. The multi-head is made by gluing together a glass plate 27 having multi-grooves 26 and a heating head 28 similar to that described in FIG. 3-a. Note that FIG. 3-a is a sectional view of the head 13 along the ink flow path, and FIG. 3-b is a cross-sectional view taken along the line AB in FIG. 3-a. Conventionally, as this type of recording liquid, for example,
No. 8361, Special Publication No. 51-40484, Special Publication No. 52-13126
As shown in Japanese Patent Publication No. 52-13127 and Japanese Patent Application Laid-Open No. 50-95008, various dyes and pigments are dissolved or dispersed in aqueous or non-aqueous solvents.
Preferred conditions for this type of recording liquid include: (1) liquid physical properties (viscosity, surface tension, electrical conductivity, etc.) that match the ejection conditions (piezoelectric element drive voltage, drive frequency, orifice shape and material, orifice diameter, etc.); ). (2) Stable for long-term storage and should not cause clogging. (3) Fixation is fast on the recording material (paper, film, etc.) and the dot periphery is smooth with little bleeding. (4) The color tone of the printed image is clear and the density is high. (5) The printed image must have excellent water resistance and light resistance. (6) Do not damage the materials surrounding the recording liquid (container, connecting tube, sealing material, etc.). (7) It must be safe in terms of odor, toxicity, flammability, etc. etc. It is quite difficult to simultaneously satisfy the above characteristics. The prior art described above was unsatisfactory in this respect. Further, preferred dyes and pigments used in this type of recording liquid are disclosed in, for example, Japanese Patent Publication No. 52-13126 and Japanese Patent Application Laid-Open No.
No. 49-89534, Japanese Patent Application Publication No. 1973-95008, Japanese Patent Application Publication No. 1973-
Pigments such as azo direct dyes, acid dyes, basic dyes, and carbon black are known, as disclosed in No. 77706 and Japanese Patent Application Laid-open No. 117205/1983.
However, for example, direct dyes have problems in concentration and long-term storage stability, acidic dyes have problems in water resistance, basic dyes have problems in light and water resistance, and pigments have problems in dispersion stability. In addition to these dyes and pigments, the above-mentioned publications also contain descriptions of reactive dyes. However, this dye was originally designed to react with groups with active protons such as hydroxyl groups and amino groups, and when dissolved in solvents such as water and glycols, it is easily hydrolyzed and its storage stability is essentially limited. There are some difficulties. I have not yet seen any proposals that focus on this point and make improvements. On the other hand, in the technical field of textile dyeing, proposals have been made to try to improve the stability of dye baths by adding organic acids, as seen in, for example, Japanese Patent Publication No. 16013/1973. However, this case is completely unrelated to various performances such as ejection stability, printing characteristics, and image characteristics in the technical field of the present invention. The present invention eliminates the drawbacks of the prior art described above and simultaneously satisfies discharge stability, long-term storage stability, fixing performance, image density, clarity, water resistance, and light resistance, and furthermore, eliminates odor, toxicity, and flammability. The object of the present invention is to provide a recording liquid for an inkjet that is highly practical and has excellent safety. Therefore, the recording liquid of the present invention contains 0.1 to 20% by weight of a dye represented by the general formula SDX (where S is a sulfonic group, a carboxyl group,
It is a group that makes dyes selected from hydroxyl groups and amino groups soluble in water, D is a base dye molecule selected from azo dyes, anthraquinone dyes, phthalocyanine dyes, and metal complex dyes, and X is a reactive group, and It is a residue selected from the group. ;
