Abstract

A pretreatment agent was provided for ink jet textile printing. The pretreatment agent contains a polyvalent metal compound, an anionic resin emulsion, a fluorinated water and oil repellent, and water.

Claims (40)

1. A pretreatment agent for ink jet textile printing on a cloth using an aqueous white ink composition which comprises white pigment, a urethane resin emulsion, and water, the pretreatment agent comprising:

a polyvalent metal compound;

an anionic resin emulsion;

a fluorinated water and oil repellent;

and

water,

wherein said polyvalent metal compound aggregates said white pigment on the surface of said cloth,

said anionic resin emulsion prevents color unevenness,

said fluorinated water and oil repellent reduces at least either the pigment concentration in said white ink composition or the resin concentration in said white ink composition.

2. The pretreatment agent according to claim 1 , wherein the polyvalent metal compound is at least one of calcium nitrate and calcium chloride.

3. The pretreatment agent according to claim 1 , wherein the content of the metal component of the polyvalent metal compound is 1% to 5% by mass relative to the total mass of the pretreatment agent.

4. The pretreatment agent according to claim 1 , wherein the anionic resin emulsion content in terms of solid content is 1% to 5% by mass relative to the total mass of the pretreatment agent, and the fluorinated water and oil repellent content in terms of solid content is 0.2% to 2% by mass relative to the total mass of the pretreatment agent.

5. An ink jet textile printing ink set for ink jet textile printing on a cloth comprising:

the pretreatment agent as set forth in claim 1 ; and

an ink jet textile printing aqueous white ink composition containing 3% to 11% by mass of a white pigment, 5% to 11% by mass of a urethane resin emulsion, and water.

6. An ink jet textile printing ink set for ink jet textile printing on a cloth comprising:

the pretreatment agent as set forth in claim 2 ; and

an ink jet textile printing ink composition containing 3% to 11% by mass of a pigment, 5% to 11% by mass of a urethane resin emulsion, and water.

7. An ink jet textile printing ink set for ink jet textile printing on a cloth comprising:

the pretreatment agent as set forth in claim 3 ; and

an ink jet textile printing ink composition containing 3% to 11% by mass of a pigment, 5% to 11% by mass of a urethane resin emulsion, and water.

8. An ink jet textile printing ink set for ink jet textile printing on a cloth comprising:

the pretreatment agent as set forth in claim 4 ; and

an ink jet textile printing ink composition containing 3% to 11% by mass of a pigment, 5% to 11% by mass of a urethane resin emulsion, and water.

9. The ink jet textile printing ink set according to claim 5 , wherein the white pigment content in the ink jet textile printing ink composition is 5% to 11% by mass.

10. An ink jet textile printing method using the ink jet textile printing ink set as set forth in claim 5 , the method comprising:

pretreating a cloth by applying the pretreatment agent to the cloth; and
