The present invention relates to a recording liquid suitable for use in an inkjet system in which recording is performed by ejecting liquid droplets from an orifice of a writing instrument or a recording head, particularly an inkjet system that uses thermal energy, and an inkjet recording method using the same. . BACKGROUND ART Writing instruments (fountain pens, felt pens, etc.) for recording on recording materials such as paper have traditionally used inks prepared by dissolving various dyes in water or other organic solvents. Furthermore, in the so-called inkjet method, in which recording is performed by discharging the liquid in the recording head using vibrations caused by a piezo vibrator or electrostatic attraction caused by the application of high voltage, various dyes are dissolved in water or organic solvents. It is known to use ink. However, compared to ink for general stationery, ink for ink jets is required to meet more stringent conditions in many characteristics. The inkjet recording method generates little noise and can perform high-speed recording or color recording on plain paper without requiring any special fixing treatment, and various types of inkjet recording methods are being actively researched. In this type of recording method, the ink used must have physical properties such as viscosity and surface tension within appropriate ranges, and must have high dissolution stability and not clog the fine orifice. , it is required to provide a recorded image with a sufficiently high density, and that physical property values do not change or solid content does not precipitate during storage. In addition to the above properties, it also has the ability to record without being restricted by the type of recording material, has a high fixing speed, and has excellent water resistance, solvent resistance (especially alcohol resistance), light resistance, and abrasion resistance. There are also demands for properties such as the ability to provide images with excellent resolution and high resolution. Among the injection recording methods, for example, JP-A-54
The method disclosed in No. 51837 differs greatly from other methods in that thermal energy is applied to obtain the motive force for ejecting droplets. That is, in this method, thermal energy is generated in the recording head section in response to a supplied recording signal, and bubbles are instantaneously generated, grown, and disappeared in the recording liquid that is affected by the thermal energy. Recording is performed by ejecting droplets from an orifice at the tip of the recording head due to changes in the pressure energy of the recording liquid. This recording method is not only extremely effective for so-called on-demand recording, but also has a high-density multi-orifice structure in the recording head and can easily realize full-line recording operations, making it possible to produce high-resolution images. It has the advantage that it can be obtained at high speed. However, in this recording method, thermal energy is directly applied to the recording liquid, and the temperature instantaneously reaches over 250°C, especially in the bubble generating area. Therefore, in addition to the above-mentioned general inkjet ink properties, recording liquid properties that satisfy continuous recording performance over a long period of time or ejection stability after a long period of recording suspension are particularly thermally stable. Other properties are also required, such as high performance, no clogging of orifices, and no change in ink color due to heat. but,
A recording liquid that satisfies all of these characteristics has not been known so far. An object of the present invention is to provide a recording liquid for writing instruments such as felt pens and for inkjet recording. Another object of the present invention is to provide a recording liquid for inkjet recording that uses thermal energy, which extends the life of a recording head and has high recording stability over a long period of time, and an inkjet recording method using the same. It's about doing. The above and other objects are achieved by the invention below.

In order to prepare a recording liquid used in a type of recording method in which the recording liquid is charged, a resistivity adjuster such as inorganic salts such as lithium chloride, ammonium chloride, and sodium chloride is used. Further, urea and thiourea are preferably used as water retention improvers at the tip of the discharge orifice. Incidentally, in the case of a type in which recording liquid is ejected by the action of thermal energy, thermal physical property values (for example, specific heat, coefficient of thermal expansion, thermal conductivity, etc.) may be adjusted. When the recording liquid of the present invention is used as a so-called recording liquid for writing instruments, it is necessary to adjust the physical property values in consideration of viscosity, compatibility with recording members made of various materials, etc. The invention will be explained in more detail in the following examples. Example 1 A recording head for ink jet recording in which ink is ejected by the action of thermal energy was prepared as follows. First, a SiO 2 layer (lower layer) was formed on an alumina substrate to a thickness of 5 ÎŒm by sputtering, and then HfB 2 was deposited to a thickness of 1000 Ã
as a heating resistor layer.
Furthermore, after laminating aluminum as an electrode to a thickness of 3000 Ã
, selective etching was performed to form a layer of 50 ÎŒm x 200 ÎŒm.
A heating resistor pattern was formed. Next, two layers of SiO were laminated as a protective layer (upper layer) to a thickness of 3500 Ã
by sputtering to form an electric/thermal converter on the substrate, and then a glass plate with grooves of 50 ÎŒm width x 50 ÎŒm depth was cut into the grooves. They were joined so that the heating resistors matched. Subsequently, the end face of the orifice was polished so that the distance between the tip of the heating resistor and the orifice was 250 ÎŒm to prepare a recording head. On the other hand, a recording liquid was prepared according to the following formulation using the dye having the chemical structural formula No. 1 mentioned above. Paint with structural formula No. 1 3 parts by weight diethylene glycol 25 ã N-methyl-2-pyrrolidone 20 ã Water 52 ã The above ingredients were thoroughly mixed and dissolved in a container, and then pressurized using a Teflon filter with a pore size of 1ÎŒ. After filtration, it was degassed using a vacuum pump to obtain a recording liquid. This recording liquid was supplied to the recording head described above, and a continuous printing test was conducted. To the recording head: 10ÎŒsec,
A rectangular voltage pulse printing signal of 40 V was continuously applied at a period of 500 ÎŒsec. As a result, the recording liquid was sufficiently durable for 150 hours of continuous recording. Examples 2 to 7 Recording liquids were prepared in the same manner as in Example 1, except that the type of dye and the amount of dye blended were changed. A 150-hour continuous printing test similar to that in Example 1 was conducted using these recording liquids. However, the print signal
It was added at a period of 350ÎŒsec. Table 1 shows the durability times in these tests. The durability time was defined as the time when the ink flight became unstable and recording in accordance with the pulse signal began to become impossible.
