Abstract
Official abstract text for this publication.
There is provided an ink set including a water-based cleaning transportation liquid, and a disperse dye ink composition, in which the water-based cleaning transportation liquid includes water and at least one of an aromatic sulfonate formalin condensate and a lignin sulfonate as a dispersing agent I, without including a coloring material, and the disperse dye ink composition includes a disperse dye, water, and a dispersing agent II.
First claim
Opening claim text (preview).
What is claimed is: 1 . An ink set comprising: a water-based cleaning transportation liquid; and a disperse dye ink composition, wherein the water-based cleaning transportation liquid includes water and at least one of an aromatic sulfonate formalin condensate and a lignin sulfonate as a dispersing agent I, without including a coloring material, and the disperse dye ink composition includes a disperse dye, water, and a dispersing agent II. 2 . The ink set according to claim 1 , wherein a content I of the dispersing agent I with respect to a total amount of the water-based cleaning transportation liquid is 2.0 mass % to 30 mass %, a content II of the dispersing agent II is 2.0 mass % or more with respect to the total amount of the disperse dye ink composition, and a ratio A of the content II with respect to the content I (content II/content I) is 0.10 to 3.0. 3 . The ink set according to claim 2 , wherein the content I of the dispersing agent I with respect to the total amount of the water-based cleaning transportation liquid is 5.0 mass % to 15 mass %, the content II of the dispersing agent II is 2.0 mass % or more with respect to the total amount of the disperse dye ink composition, and the ratio A of the content II with respect to the content I (content II/content I) is 0.30 to 2.0. 4 . The ink set according to claim 1 , wherein the content I of the dispersing agent I with respect to the total amount of the water-based cleaning transportation liquid is 2.0 mass % to 30 mass %, the content II of the dispersing agent II with respect to the total amount of the disperse dye ink composition is less than 2.0 mass %, and a ratio B of the content II with respect to the content I (content II/content I) is 0.050 to 1.3. 5 . The ink set according to claim 4 , wherein the content I of the dispersing agent I with respect to the total amount of the water-based cleaning transportation liquid is 5.0 mass % to 15 mass %, the content II of the dispersing agent II with respect to the total amount of the disperse dye ink composition is less than 2.0 mass %, and a ratio B of the content II with respect to the content I (content II/content I) is 0.15 to 0.50. 6 . The ink set according to claim 1 , wherein the water-based cleaning transportation liquid further includes a moisturizing agent I, a content of the moisturizing agent I with respect to the total amount of the water-based cleaning transportation liquid is 5.0 mass % to 30 mass %, the disperse dye ink composition further includes a moisturizing agent II, and a content of the moisturizing agent II with respect to the total amount of the disperse dye ink composition is 5.0 mass % to 30 mass %. 7 . The ink set according to claim 1 , wherein the water-based cleaning transportation liquid further includes a surface tension adjusting agent, and a surface tension of the water-based cleaning transportation liquid is 35 mN/m or less. 8 . The ink set according to claim 1 , wherein the water-based cleaning transportation liquid further includes a pH adjusting agent I, a pH of the water-based cleaning transportation liquid is 7.0 to 10.0, the disperse dye ink composition further includes a pH adjusting agent II, and a pH of the disperse dye ink composition is 7.0 to 10.0. 9 . The ink set according to claim 1 , wherein the dispersing agent II includes at least one of an aromatic sulfonate formalin condensate and a lignin sulfonate. 10 . The ink set according to claim 1 , wherein at least one of the dispersing agent I and the dispersing agent II includes at least one of an aromatic sulfonate formalin condensate Na salt and an aromatic sulfonate formalin condensate Ca salt. 11 . The ink set according to claim 1 , wherein at least one of the dispersing agent I and the dispersing agent II includes at least one of a lignin sulfonate Na salt and a lignin sulfonate Ca salt. 12 . The ink set according to claim 1 , wherein at least one of the dispersing agent I and the dispersing agent II includes a naphthalene sulfonate formalin condensate.
