Abstract

An aspect of the present disclosure relates to an ink-jet treatment liquid containing: emulsified particles containing silicone oil; a surfactant; and an aqueous medium, wherein a content of the silicone oil is equal to or greater than 5 mass % and equal to or less than 15 mass % with respect to the entire treatment liquid, and the surfactant contains: a first surfactant containing an alkyl group having from 12 to 14 carbon atoms; and a second surfactant containing an alkyl group having from 16 to 18 carbon atoms.

First claim

1 . An ink-jet treatment liquid comprising:
emulsified particles containing silicone oil, a surfactant and an aqueous medium, wherein a content of the silicone oil is equal to or greater than 5 mass % and equal to or less than 15 mass % with respect to the entire of the treatment liquid, the surfactant comprises a first surfactant containing an alkyl group having from 12 to 14 carbon atoms and a second surfactant containing an alkyl group having from 16 to 18 carbon atoms, wherein the first and second surfactants are polyoxyethylene alkyl ethers, and a content of the first surfactant and a content of the second surfactant satisfy the following equation:

 and
a total content of the first surfactant and the second surfactant is equal to or greater than 0.5 mass % and equal to or less than 2.5 mass % with respect to the entire of the treatment liquid.

2 . The ink-jet treatment liquid according to claim 1 , wherein
the first surfactant comprises two or more compounds containing alkyl groups having different numbers of carbon atoms.

3 . The ink-jet treatment liquid according to claim 1 , wherein
the second surfactant comprises two or more compounds containing alkyl groups having different numbers of carbon atoms.

4 . The ink-jet treatment liquid according to claim 1 , wherein
a total content of the first surfactant and the second surfactant is equal to or greater than 9.0 mass % and equal to or less than 33.0 mass % with respect to a content of the silicone oil.

5 . The ink-jet treatment liquid according to claim 1 , wherein
the emulsified particles have an average particle diameter of equal to or greater than 100 nm and equal to or less than 250 nm.

6 . The ink-jet treatment liquid according to claim 5 , wherein
when the ink-jet treatment liquid is stored at 60° C. for 30 days, an average particle diameter X of the emulsified particles in the treatment liquid before storage and an average particle diameter Y of the emulsified particles in the treatment liquid after storage satisfy the following formula:

7 . The ink-jet treatment liquid according to claim 1 , wherein the ink-jet treatment liquid is used for textile printing.

8 . An ink-jet textile printing method comprising:
ejecting an ink from a recording head in an image formation region of an object to be textile-printed; and ejecting a treatment liquid from a treatment head in at least the image formation region of the object to be textile-printed, wherein the treatment liquid is the ink-jet treatment liquid according to claim 1 .
