Abstract
Official abstract text for this publication.
One aspect of the present invention relates to an inkjet treatment liquid containing a water-soluble cationic polymer and an organic acid salt, wherein a content of the water-soluble cationic polymer is 0.1 wt % or more and less than 10 wt % with respect to the entire amount of the inkjet treatment liquid.
First claim
Opening claim text (preview).
The invention claimed is: 1 . An inkjet treatment liquid, comprising a water-soluble cationic polymer, an organic acid salt, and a metal salt, wherein a content of the water-soluble cationic polymer is 0.1 wt % or more and less than 10 wt % with respect to the entire amount of the inkjet treatment liquid, and wherein a content of the organic acid salt is larger than a content of the metal salt. 2 . The inkjet treatment liquid according to claim 1 , wherein a content of the organic acid salt is 0.1 to 20 wt % with respect to the entire amount of the inkjet treatment liquid. 3 . The inkjet treatment liquid according to claim 1 , wherein a content of the organic acid salt is larger than a content of the water-soluble cationic polymer. 4 . The inkjet treatment liquid according to claim 3 , wherein a content of the organic acid salt is 1 to 15 wt % with respect to the entire amount of the inkjet treatment liquid. 5 . The inkjet treatment liquid according to claim 1 , wherein a content of the metal salt is 0.1 to 5 wt % with respect to the entire amount of the inkjet treatment liquid, and a content of the organic acid salt is 1 to 15 wt % with respect to the entire amount of the inkjet treatment liquid. 6 . An inkjet treatment liquid, comprising a water-soluble cationic polymer and an organic acid salt, wherein a content of the water-soluble cationic polymer is 0.1 wt % or more and less than 10 wt % with respect to the entire amount of the inkjet treatment liquid wherein the organic acid salt is an organic acid magnesium salt, and wherein a content of the organic acid magnesium salt is 12 to 15 wt % with respect to the entire amount of the inkjet treatment liquid. 7 . The inkjet treatment liquid according to claim 1 , wherein the treatment liquid is for textile printing. 8 . An inkjet textile printing apparatus, comprising: at least a processing head configured to eject a treatment liquid to at least an image formation area of a textile printing target; a recording head configured to eject an ink to the image formation area of the textile printing target; and a mounting table configured to convey the textile printing target, wherein the treatment liquid to be ejected from the processing head is the inkjet treatment liquid according to claim 1 . 9 . The inkjet treatment liquid according to claim 6 , further comprising a metal salt. 10 . The inkjet treatment liquid according to claim 9 , wherein a content of the organic acid salt is larger than a content of the metal salt. 11 . The inkjet treatment liquid according to claim 6 , wherein the treatment liquid is for textile printing. 12 . An inkjet textile printing apparatus, comprising: at least a processing head configured to eject a treatment liquid to at least an image formation area of a textile printing target; a recording head configured to eject an ink to the image formation area of the textile printing target; and a mounting table configured to convey the textile printing target, wherein the treatment liquid to be ejected from the processing head is the inkjet treatment liquid according to claim 6 .
