Abstract
Official abstract text for this publication.
An aqueous inkjet ink set for textile printing is disclosed, the aqueous inkjet ink set including two or more aqueous inkjet inks that include a black ink, wherein among the charge density Cd values measured by the streaming potential method for the two or more aqueous inkjet inks, the Cd value (CdK) for the black ink is the highest, and the absolute value of the difference between the Cd value (CdK) for the black ink and the Cd value (Cd2) for the aqueous inkjet ink having the second highest Cd value is 80 μeq/g or greater. A method for producing a printed item is also disclosed.
First claim
Opening claim text (preview).
What is claimed is: 1. An aqueous inkjet ink set for textile printing comprising two or more aqueous inkjet inks including a black ink, wherein among charge density Cd values measured by a streaming potential method for the two or more aqueous inkjet inks, a Cd value (CdK) for the black ink is highest, and an absolute value of a difference between the Cd value (CdK) for the black ink and a Cd value (Cd2) for an aqueous inkjet ink having a second highest Cd value is 80 μeq/g or greater. 2. The aqueous inkjet ink set for textile printing according to claim 1 , wherein an absolute value of a difference between the Cd value (CdK) for the black ink and the Cd value (Cd2) for the aqueous inkjet ink having the second highest Cd value is 100 μeq/g or greater. 3. The aqueous inkjet ink set for textile printing according to claim 1 , wherein at least one of the two or more aqueous inkjet inks comprises a water-dispersible urethane resin and at least one water-dispersible resin selected from the group consisting of a water-dispersible (meth)acrylic resin and a water-dispersible styrene/(meth)acrylic resin. 4. The aqueous inkjet ink set for textile printing according to claim 1 , wherein each of the two or more aqueous inkjet inks comprises 1 to 30% by mass of a pigment relative to a total mass of the aqueous inkjet ink. 5. A method for producing a printed item using the aqueous inkjet ink set for textile printing according to claim 1 , the method comprising printing the two or more aqueous inkjet inks onto a substrate using an inkjet recording method. 6. The method according to claim 5 , wherein an absolute value of a difference between the Cd value (CdK) for the black ink and the Cd value (Cd2) for the aqueous inkjet ink having the second highest Cd value is 100 μeq/g or greater. 7. The method according to claim 5 , wherein at least one of the two or more aqueous inkjet inks comprises a water-dispersible urethane resin and at least one water-dispersible resin selected from the group consisting of a water-dispersible (meth)acrylic resin and a water-dispersible styrene/(meth)acrylic resin. 8. The method according to claim 5 , wherein each of the two or more aqueous inkjet inks comprises 1 to 30% by mass of a pigment relative to a total mass of the aqueous inkjet ink.
