Abstract
The image forming method of the present invention includes applying an ink and a first treatment liquid onto a fabric in a wet-on-wet manner to each other, the ink containing a pigment and a first resin, a first treatment liquid containing a second resin that reacts with or interacts with the first resin to aggregate. The viscosity of the first treatment liquid at 25° C. is lower than the viscosity of the ink at 25° C.
Claims15
An image forming method, comprising:
- applying an ink and a first treatment liquid onto a fabric in a wet-on-wet manner to each other, the ink containing a pigment and a first resin, the first treatment liquid containing a second resin that reacts with or interacts with the first resin to aggregate, wherein
- a second treatment liquid containing an aggregating agent that aggregates the first resin is further applied, and the second treatment liquid and the ink are applied in the wet-on-wet manner to each other,
- a viscosity of the first treatment liquid at 25° C. is lower than a viscosity of the ink at 25° C.,
- a viscosity of the second treatment liquid at 25° C. is lower than the viscosity of the first treatment liquid at 25° C., and
- wherein in the applying in the wet-on-wet manner, the second treatment liquid, the ink, and the first treatment liquid are applied onto the fabric in this order.

An ink set for ink jet textile printing, the ink set comprising:
- an ink containing a pigment, a first resin, a water-soluble organic solvent, and water;
- and a first treatment liquid containing, a second resin, a water-soluble organic solvent, and water, the second resin reacting with or interacting with the first resin to aggregate;
- a second treatment liquid containing an aggregating agent, a water-soluble organic solvent, and water, the aggregating agent aggregating the first resin, wherein
- a viscosity of the first treatment liquid at 25° C. is lower than a viscosity of the ink at 25° C.,
- a viscosity of the second treatment liquid at 25° C. is lower than the viscosity of the first treatment liquid at 25° C., wherein
- the first treatment liquid is a post-treatment liquid to be applied after the ink is applied, and the second treatment liquid is a pretreatment liquid to be applied before the ink is applied.
