摘要:
The present invention provides an ink for ink jet recording, in which the formation of a high-quality image is possible, image keeping quality is excellent, the ink is not dried at an ink jet head, and ejection stability is high, wherein the ink for ink jet recording comprises: at least one dye having a specific structure, in which the at least one dye is dissolved or dispersed in an aqueous medium; and a betaine surfactant, wherein, when the ink has been shaken 30 times or more for 10 seconds and allowed to stand for 3 minutes, a bubble height in the ink is 30 mm or less.
摘要:
An inkjet recording ink including an aqueous medium having dissolved therein a phthalocyanine dye, wherein the phthalocyanine dye is a water-soluble dye having an oxidation potential more positive than 1.0 V (vs SCE) and the ink includes a water-miscible organic solvent having a vapor pressure of 2,000 Pa or less at 20° C.; and an inkjet recording method using the ink.
摘要:
An inkjet recording ink comprising an aqueous medium having dissolved or dispersed therein a magenta dye selected from azo dyes, wherein the magenta dye is a dye having an oxidation potential more positive than 1.0 V (vs SCE) and at the same time, a water-miscible organic solvent having a vapor pressure of 2,000 Pa or less at 20° C. is contained; and an inkjet recording method using the ink. By virtue of such a constitution, an inkjet recording ink and an inkjet recording method are provided, which can ensure high ejection stability, good color hue of the obtained image, no drying of the ink at the ink jet head, excellent fastness to light and water, image quality free from defective such as fineline bleeding under high-humidity condition, and good preservability of the image under severe conditions, and furthermore can ensure high storability and high ejection stability even after aging for a long time or under severe conditions.

摘要:
The object of the present invention is to provide an inkjet recording ink ensuring excellent ejection stability even after aging of the ink and also exhibiting excellent weather resistance; provide an inkjet recording ink ensuring less blurring of the image drawn, in addition to excellent ejection stability and weather resistance; and provide a yellow ink and a dark yellow ink, which can contribute to realization of a pictorial quality with excellent color balance as a constituent ink of an ink set. These objects of the present invention can be achieved by an inkjet recording ink comprising an aqueous medium containing a yellow dye, particularly, a yellow dye represented by formula (1), having spectral absorption characteristics such that the maximum absorption wavelength is in the region from 390 to 470 nm and the absorption long-wave end has a tailing of a specified value or less, and antioxidative characteristics such that the ozone enforced discoloration rate constant is 5.0×10−2 [hour−1] or less. Furthermore, when the ink contains a diamino compound represented by formula (A), a carbonyl group (or sulfo group or the like)-containing cyclic compound represented by formula (B) and an organic solvent having a specific structure, the effect of the present invention is enhanced.
