Abstract

An ink jet ink composition containing a metal pigment, and a liquid medium component, in which the metal pigment is made of a metal particle, the metal particle is surface-modified with a surface treatment agent, the surface treatment agent is at least one selected from the group consisting of a compound represented by formula (1) below and a compound represented by formula (2) below, and the ink jet ink composition is a water-based ink or a solvent-based ink:(R—O)aP(O)(OH)3-a   (1)(R)P(O)(OH)2   (2)where R is independently a hydrocarbon group having a carbon skeleton having 13 or more carbon atoms, and a is 1 or 2.

First claim

What is claimed is:

1 . An ink jet ink composition comprising:
a metal pigment; and a liquid medium component, wherein the metal pigment is made of a metal particle, the metal particle is surface-modified with a surface treatment agent, the surface treatment agent is at least one selected from the group consisting of a compound represented by formula (1) below and a compound represented by formula (2) below, and the ink jet ink composition is a water-based ink or a solvent-based ink:
(R—O) a P(O)(OH) 3-a   (1)

(R)P(O)(OH) 2   (2)

wherein R is independently a hydrocarbon group having a carbon skeleton having 13 or more carbon atoms, and a is 1 or 2.

2 . The ink jet ink composition according to claim 1 , wherein
in the surface treatment agent, R in formula (1) or formula (2) is a chain aliphatic hydrocarbon group.

3 . The ink jet ink composition according to claim 1 , wherein
in the surface treatment agent, R in formula (1) and formula (2) is a hydrocarbon group having no substituent, and the ink jet ink composition is a solvent-based ink.

4 . The ink jet ink composition according to claim 1 , wherein
the ink jet ink composition is a solvent-based ink containing an organic solvent as the liquid medium component or is a water-based ink containing water as the liquid medium component.

5 . The ink jet ink composition according to claim 1 , wherein
in the surface treatment agent, R in formula (1) and formula (2) is a hydrocarbon group having a substituent, and the ink jet ink composition is a water-based ink.

6 . The ink jet ink composition according to claim 1 , wherein
the metal particle is made of aluminum or an aluminum alloy.

7 . The ink jet ink composition according to claim 1 , wherein
the metal particle is a scaly particle.

8 . The ink jet ink composition according to claim 1 , wherein
a content of the surface treatment agent is 1.0 part by mass or more and 50 parts by mass or less with respect to 100 parts by mass of the metal particle.

9 . The ink jet ink composition according to claim 1 , wherein
in the surface treatment agent, R in formula (1) and formula (2) has a carbon skeleton having 15 or more carbon atoms.

10 . An ink set comprising:
the ink jet ink composition according to claim 1 ; and an ink jet ink composition which is a colored ink containing a coloring material.

11 . A recording method comprising
an adhesion step of ejecting the ink jet ink composition according to claim 1 from an ink jet head and adhering the ink jet ink composition to a recording medium.

12 . The recording method according to claim 11 , further comprising
a primary heating step of heating the ink jet ink composition adhered in the adhesion step.

13 . The recording method according to claim 11 , further comprising
an adhesion step of ejecting an ink jet ink composition, which is a colored ink containing a coloring material, from the ink jet head and adhering the ink jet ink composition to the recording medium, wherein a colored image having a metallic glossiness is formed.
