    摘要: An object of the present invention is to provide an ink composition with which images with high quality without white streaks or roughness can be provided even when the images are printed at a low resolution on coated printing paper such as art paper. The ink composition for ink jet recording at least includes a colorant, water, an alcohol solvent, and a surfactant, wherein the alcohol solvent contains a slightly water-soluble alkanediol, a water-soluble 1,2-alkanediol, and a dialkylene glycol.

    摘要: An ink composition that can form high-quality images free of white streaks and harshness on actual printing paper, such as art paper, even at low resolution and that can reduce the occurrence of curling even with thin actual printing paper having a low grammage is provided.An ink jet printing ink composition includes at least a colorant, water, an alcohol solvent, and a surfactant, wherein the alcohol solvent contains a poorly water-soluble alkane diol, a water-soluble 1,2-alkane diol, and a water-soluble symmetrical alkane diol having a hydroxy group at both ends.

    摘要: It is an object of the present invention to provide a yellow ink composition which is superior in terms of color reproducibility not only in the high-brightness (high-L*) region, but also in the low-brightness yellow region, i.e., in the region of “low L*, a* close to zero, and high b*”, and an ink set equipped with a yellow ink which has a brightness that is high enough that graininess can be sufficiently suppressed, and which is also superior in terms of color reproducibility in the low-brightness yellow region, i.e., in the region of “low L*, a* close to zero, and high b*”. The present invention provides a yellow ink composition in which the Y value is 86 or greater when the Z value in the XYZ display system stipulated by the CIE is 23. Furthermore, the present invention also provides a yellow ink composition which contains a metal complex pigment. In particular, the yellow ink composition of the present invention can express a low-brightness yellow color with good reproducibility. Moreover, the present invention provides an ink set containing a yellow ink in which the Y value is 86 or greater when the Z value in the XYZ display system stipulated by the CIE is 23, as calculated from the ultraviolet-visible transmission spectrum of an aqueous solution diluted 10,000 times by weight or lower.
