    摘要： An ink jet recording ink including water, a water-soluble organic solvent, and at least one dye having at least one carboxyl group in the form of a free acid, wherein at least one compound selected form secondary or tertiary amine compounds represented by the following general formula (I) and at least one compound selected from the alkali metal hydroxides are contained and the pH value thereof is from 8.5 to 12: ##STR1## wherein one or two of R.sup.1, R.sup.2, and R.sup.3 are an alkyl group having 1 to 5 carbon atoms in the alkyl chain and substituted by a substituent selected from a carboxyl group, a sulfonic group, an alkali metal salt of a carboxyl group, and an alkali metal salt of a sulfonic group; and the remainder is a group selected from a hydrogen atom, an alkyl group having 1 to 5 carbon atoms, and a substituted alkyl group having 1 to 5 carbon atoms in the alkyl chain and substituted by a hydroxyl group or carbamoyl group is disclosed. The ink provides water resistance and various properties required for an ink jet recording ink.

    摘要： Provided is magenta ink that satisfies all the necessary properties including good light-fastness, good color reproducibility, especially good color reproducibility of magenta-related secondary colors of red and blue, and high reliability, and gives satisfactory high-quality images. Also provided are a color ink set for ink-jet recording, which contains the magenta ink, and an ink-jet recording method in which is used the magenta ink or the color ink set. The magenta ink contains water, a colorant and at least two water-soluble organic solvents, and its visible-light absorbance spectrum gives a first peak A (abs.) within a range of from 500 to 570 nm and a second peak B (abs.) within a range of from 300 to 350 nm with a ratio A/B falling between 0.9 and 2.5. The magenta ink is combined with cyan ink and yellow ink to form the color ink set, which contains water, colorants and at least two water-soluble organic solvents.

    摘要： An ink jet recording apparatus is provided with a recording head that ejects ink droplets, an ink tank that supplies ink to the recording head, a waste ink recovering mechanism that recovers ink droplets ejected from the recording head as waste ink, a waste-ink tank, which is connected to the waste-ink recovering mechanism and stores the waste ink, a diluent tank which is communicated with the waste-ink tank and accommodates a diluent that dilutes the waste ink, and at least one of diluent supplier, that is, one of a first diluent supplier which supplies the diluent in the diluent tank to the waste-ink tank to make the conductivity of the waste ink in the waste-ink tank substantially the same as the conductivity of the ink stored in the ink tank and a second diluent supplier which supplies the diluent in the diluent tank to the waste-ink tank to make the specific gravity of the waste ink in the waste-ink tank substantially the same as the specific gravity of the ink stored in the ink tank. Further, an ink jet recording method uses this ink jet recording apparatus.
