Abstract

A pigment printing ink jet ink composition includes a pigment, a resin particle, an organic solvent, and water. The organic solvent includes an amide compound represented by the following general formula (1).

In the general formula (1), R 1 represents a straight chain or branched alkyl group having 1 to 6 carbon atoms, and R 2 and R 3 each independently present hydrogen atoms or a straight chain or branched alkyl group having 1 to 4 carbon atoms.

First claim

What is claimed is:

1. A pigment printing ink jet ink composition comprising:
a pigment;
a resin particle;
an organic solvent; and
water,
wherein the organic solvent includes an amide compound represented by the following general formula (1),

in the general formula (1), R 1 represents a straight chain or branched alkyl group having 1 to 6 carbon atoms, and R 2 and R 3 each independently represent hydrogen atoms or a straight chain or branched alkyl group having 1 to 4 carbon atoms, and
the resin particle is a polycarbonate-based urethane resin particle having a cross-linking group that is a blocked isocyanate group obtained by blocking an isocyanate group with a chemical blocking agent selected from the group consisting of an imidazole-based compound, an imidazoline-based compound, a pyrimidine-based compound, a guanidine-based compound, an alcohol-based compound, a phenol-based compound, an active methylene-based compound, an amine-based compound, an imine-based compound, an oxime-based compound, a carbamic acid-based compound, a urea-based compound, an acid amide-based compound, an acid imide-based compound, a triazole-based compound, a pyrazole-based compound, a mercaptan-based compound, and bisulfate.

2. The pigment printing ink jet ink composition according to claim 1 , wherein a content of the amide compound represented by the general formula (1) is equal to or more than 80% by mass with respect to a total mass of the organic solvent.

3. The pigment printing ink jet ink composition according to claim 1 , which is used in printing onto a polyester cloth.

4. The pigment printing ink jet ink composition according to claim 1 , wherein a content of the amide compound represented by the general formula (1) is equal to or more than 16% by mass and equal to or less than 30% by mass with respect to a total mass of the pigment printing ink jet ink composition.

5. The pigment printing ink jet ink composition according to claim 1 , wherein a content of the amide compound represented by the general formula (1) is equal to or more than 1.5 at a mass ratio with respect to the resin particle.

6. A pigment printing ink jet recording method comprising:
ejecting the pigment printing ink jet ink composition according to claim 1 from an ink jet nozzle and attaching the pigment printing ink jet ink composition onto a cloth.

7. A pigment printing ink jet recording method comprising:
ejecting the pigment printing ink jet ink composition according to claim 2 from an ink jet nozzle and attaching the pigment printing ink jet ink composition onto a cloth.

8. A pigment printing ink jet recording method comprising:
ejecting the pigment printing ink jet ink composition according to claim 3 from an ink jet nozzle and attaching the pigment printing ink jet ink composition onto a cloth.

9. A pigment printing ink jet recording method comprising:
ejecting the pigment printing ink jet ink composition according to claim 4 from an ink jet nozzle and attaching the pigment printing ink jet ink composition onto a cloth.

10. A pigment printing ink jet recording method comprising:
ejecting the pigment printing ink jet ink composition according to claim 5 from an ink jet nozzle and attaching the pigment printing ink jet ink composition onto a cloth.
