Abstract
Official abstract text for this publication.
An ink jet ink composition includes a disperse dye, and a sodium naphthalene sulfonate formalin condensate, in which a ratio of a concentration of sodium ions with respect to a content of the sodium naphthalene sulfonate formalin condensate (Na (ppm)/NSF (% by mass)) is 75 to 550.
First claim
Opening claim text (preview).
What is claimed is: 1. An ink jet ink composition comprising: a disperse dye; a silicone-based surfactant; and a sodium naphthalene sulfonate formalin condensate, wherein a ratio of a concentration of sodium ions with respect to a content of the sodium naphthalene sulfonate formalin condensate (Na (ppm)/NSF (% by mass)) is 75 to 550. 2. The ink jet ink composition according to claim 1 that is prepared by removing cations by a cation exchange membrane. 3. The ink jet ink composition according to claim 1 , wherein the content of the sodium naphthalene sulfonate formalin condensate is 10 parts by mass to 300 parts by mass with respect to 100 parts by mass of a solid content concentration of the disperse dye. 4. The ink jet ink composition according to claim 1 that is used in an atmosphere opening type recording apparatus. 5. The ink jet ink composition according to claim 1 , wherein a content of the silicone-based surfactant is 5.0 parts by mass to 45 parts by mass with respect to 100 parts by mass of the solid content of the disperse dye. 6. The ink jet ink composition according to claim 5 , further comprising: a moisturizer; a chelating agent; and a pH adjusting agent, wherein the ink jet ink composition is prepared by obtaining a dispersion by mixing the silicone-based surfactant with a liquid mixture including the disperse dye and the sodium naphthalene sulfonate formalin condensate, heating the dispersion to 60° C. or higher and cooling the dispersion to 25° C. or lower, and mixing the moisturizer, the chelating agent, and the pH adjusting agent with the dispersion after the heating of the dispersion and filtering the mixture. 7. A production method of an ink jet ink composition comprising: obtaining a dispersion by mixing a silicone-based surfactant with a liquid mixture including a disperse dye and a sodium naphthalene sulfonate formalin condensate; heating the dispersion to 60° C. or higher and cooling the dispersion to 25° C. or lower; and mixing a moisturizer, a chelating agent, and a pH adjusting agent with the dispersion after the heating of the dispersion and filtering the mixture.
