    摘要: An inventive ink comprises a water-soluble dye or a pigment as a coloring agent, 5 to 15% by weight of polyvalent alcohol monoalkyl ether selected from the group consisting of tetraethylene glycol monoalkyl ethers and pentaethylene glycol monoalkyl ethers, 5 to 50% by weight of polyvalent alcohol, and pure water. When recording is performed in accordance with the ink-jet recording system by using the inventive ink, an excellent result is obtained from any viewpoint concerning, for example, the recording characteristic, the fixation to an objective recording material, the quick drying characteristic, the printing quality characteristic, and the low odor characteristic. The inventive ink is useful as an ink to be used for ink-jet recording apparatuses based on various recording systems, making it possible to obtain an excellent recording result.

    摘要: A recording ink composition comprises pure water, a water-soluble dye, a polyvalent alcohol, and phosphoric acid. When iron is contained as an impurity in the recording ink composition, the iron and phosphoric acid form a ferric (III) phosphato complex ion represented by �Fe(HP0.sub.4)(H.sub.2 O)!.sup.+. Owing to the formation of the complex ion, the recording ink composition is prevented from discoloration which would be otherwise caused by iron ion. Further, the recording ink composition is prevented from formation and deposition of iron compounds. Therefore, the obtained ink has an excellent color tone, and the ink avoids blocking at a nozzle of a printing head or the like of an ink-jet printer.

    摘要: The object of the invention is to provide a method for cleaning circulation water, which reduces the cost of operation and maintenance as much as possible, without a cumbersome cleaning operation such as by detaching electrode plates from an electrolysis cleaning tank and removing scale from inside the tank, and to provide a device used in this method. Accordingly, the present invention provides a method for cleaning circulation water, comprising the steps of flowing circulation water to be cleaned between electrode plates placed in a face-to-face manner between one another; and applying DC voltage between the electrode plates, allowing one or more metal ions contained in the circulation water to be precipitated onto the negative electrode plates by electrolysis, to clean the circulation water, wherein the electrode plates used are made of titanium plates, and wherein a desired amount of current flows, while an anodized oxide coating formed on the surface of the positive electrode plates is compulsively subject to dielectric breakdown by increasing the voltage applied to the anodized oxide coating. FIG. 1 is a representative drawing.
