The present invention relates to a maintenance liquid for inkjet recording related to clogging maintenance and ink-based tanks.

不十分な点が多かった。[Prior Art] Inkjet printers have been commercialized in recent years as noiseless, high-speed, and high-resolution printers.
Since low-viscosity liquid ink is ejected from a nozzle with a micro diameter of 20 to 50 μm, it can cause ink clogging due to drying of the nozzle, printing irregularities due to increased viscosity due to evaporation of ink in the nozzle, and even air bubbles entering the ink system. There are many shortcomings in terms of reliability, such as the problem of missing dots. These problems are particularly likely to occur when the equipment is out of service for a long period of time, so as a preventive measure, the present applicant proposed
No. 16 '9636, a means has been devised for draining ink during rest and cleaning the ink afterwards. Cleaning by this means is greatly influenced by the ability of the cleaning liquid (maintenance liquid), and therefore, the reliability of the ink system largely depends on the maintenance liquid. Conventionally, this maintenance liquid has been used with a composition similar to the ink composition but without the dye, but the cleaning power was not sufficient, and the composition liquid remaining in the ink path could cause clogging. There were many deficiencies.

である。[Problems to be Solved by the Invention] The purpose of the present invention is to solve the problem of conventional maintenance fluids that have been insufficient. Furthermore, it is an object of the present invention to provide a maintenance liquid for inkjet recording, which allows the remaining maintenance liquid to be maintained for a long period of time without adversely affecting the ink system, and in which ink maintenance can be quickly carried out.

メンテナンス液に置換され廃液タンク７に排出される。The maintenance liquid is used in the inkjet recording apparatus shown in FIG. 1 is a recording head; 2 is a nozzle surface thereof; since the head 1 receives ink from an ink tank 5 for printing, a switching valve 4 is connected to the head 1 and the ink tank 5; In case of long-term suspension or cleaning of the path in case of clogging, the switching valve 4 is connected to the head 1 and the maintenance liquid tank 6, the suction cap 9 is closed, and the ink in the head is removed by the suction pump 8 for maintenance. The waste liquid is replaced with liquid and discharged into the waste liquid tank 7.
メンテナンス液として、要求される特性としては、 （１）インク経路を形成する部材をおかさないこと。As a maintenance fluid, the characteristics required are: (1) Do not damage the members that form the ink path.
（２）少量の液で、経路中のインクを排出できること。(2) The ink in the path can be discharged with a small amount of liquid.
（３）経路中に残ったメンテナンス液が目詰まりをおこ
さないこと。(3) The maintenance fluid remaining in the path does not cause clogging.
（４）インク可児てん時に、経路中のメンテナンス液が
、インクの充てんをすみやかに行なわせ、かつインク中
に気泡、及び気泡核を発生させないこと。(4) When filling the ink, the maintenance liquid in the path should fill the ink quickly and should not generate bubbles or bubble nuclei in the ink.
以上の４項目が、メンテナンス液の重要な特性であるが
、これら（１）〜（４）の項目を満足するためのインク
の特性としては、インクと相容性が高く、乾燥やインク
経路部材と反応して固形物を発生することがなく、さら
に、インク経路部材に対してぬれ性の高いものがよい。The above four items are important properties of the maintenance fluid.The characteristics of the ink that satisfies these items (1) to (4) include high compatibility with the ink, drying and ink path components. It is preferable to use a material that does not generate solid matter by reacting with the ink and has high wettability with respect to the ink path member.
また、通常のインクの粘度は、２〜１５ｍＰａ−５がイ
ンク噴出に適当な値であり、メンテナンス液も、あまり
粘度が高いと経路中を流れにくくなるため、インク粘度
の５倍以下が好ましい。Further, the viscosity of normal ink is 2 to 15 mPa-5, which is an appropriate value for ink jetting, and the maintenance liquid is also preferably 5 times or less the viscosity of the ink, because if the viscosity is too high, it becomes difficult to flow in the path.

ターの信頼性をおとす要因でもあった。In order to satisfy these characteristics, a system in which the dye that causes solid matter generation is removed from the conventional ink composition is suitable as a maintenance liquid, but among the four items mentioned above, (2) , (3) and (4) were insufficient. In other words, a maintenance liquid that simply removes the dye from the ink may not be compatible with the ink, requiring a large amount of liquid, or may cause clogging due to insufficient cleaning, or may cause wetting of the ink line member. Due to the insufficient adhesiveness, when filling with ink, the interlayer may not fill up quickly and air bubbles may be left behind in the ink, which can cause dots to drop out and reduce the reliability of inkjet printers.

オン性界面活性剤には下記の化学式で示されるものが使
用できる。According to the composition of the maintenance liquid of the present invention, methanol,
Since alcohols selected from ethanol, n-propanol, and isopropanol have very high compatibility with aqueous inks, they can clean the ink path. Further, after cleaning and discharging, some maintenance liquid remains in the ink path, but because the ink path dries due to the volatility of alcohol, maintenance is not required for a long time until the ink is refilled. Furthermore, when the maintenance liquid dries, the tube functional group contained in the liquid is 18○3M, -S.
Since the anionic surfactant having O3M, -COOM (M is H, Li, Na, K) causes molecular orientation in the ink path and in the head, the tube is formed on the surface of the ink path member and the head member. Due to the arrangement of functional groups, it becomes extremely hydrophilic and improves wettability. Therefore, when the ink is filled, the ink is quickly filled without leaving any air bubbles in the path. -S○3M, -SO3M as tube functional groups,
As the anionic surfactant having -000M (M is H, Li, Na, K), those represented by the following chemical formula can be used.

Further, the maintenance liquid of the present invention is obtained by filtering it through a membrane filter having a pore size of 1 μm or less after liquid preparation in order to remove dust, foreign matter, and particles that are generally present in water or air.

Regarding the evaluation of the cleaning power of the ink path, after cleaning with LCC maintenance liquid, the degree of contamination of the liquid remaining in the ink path conduit and the head was visually determined. In addition, maintainability after cleaning was determined by cleaning with LCC maintenance liquid, leaving the nozzles at room temperature for one month, and then observing the nozzles of the head with a microscope to determine how dirty the nozzles were. Printing reliability after refilling the ink was determined by whether or not there were any missing dots when 100 lines were printed on A4 recording paper after cleaning with Ice maintenance fluid and leaving the ink at room temperature for a month. .
