There is provided an ink composition for ink jet recording that, even on printing paper for running-on, can realize excellent gloss and good color reproduction and, at the same time, is excellent in ejection stability and recovery from clogging. The ink composition for ink jet recording comprises at least a colorant, water, an alkanediol, and a surfactant, wherein the alkanediol comprises a water soluble 1,2-alkanediol and a slightly water soluble 1,2-alkanediol, and the surfactant is a polyorganosiloxane.
摘要:
There is provided an ink composition which can yield images having silver salt photograph-like gloss and is also excellent in fixation, lightfastness, and gasfastness of recorded images. The ink composition comprises: a resin produced by emulsion polymerization of an ethylenically unsaturated monomer in the presence of a reactive emulsifier containing a hydrophilic group, a hydrophobic group and a radical reactive group; water; and a pigment.
摘要:
There is provided an ink composition that can realize high-quality images free from white streaks or roughness even in low resolution when printing paper for running-on such as art paper is used. The ink composition comprises at least a colorant, water, an alcohol solvent, and a surfactant, wherein the alcohol solvent comprises a sparingly water soluble alkanediol, a water soluble alkanediol, and a water soluble alkanetriol.
摘要:
This invention provides a magenta ink composition that, when recorded, is excellent in color development, graininess, and gloss, is less likely to cause clogging in an ink jet recording head, and is excellent in color reproduction in a high-chroma and high-lightness red region. The magenta ink composition has an L* value of not less than 60 and a b* value of not more than −17 when the a* value in CIE standard calculated from a visible absorption spectrum in a not more than 10000-fold diluted aqueous solution is 80.
