Abstract

A non-aqueous ink jet ink composition contains a glitter pigment, glycol diether represented by the following formula 1 and having a flash point of 70° C. or less, and glycol monoether represented by the following formula 2:
R 1 O—(R 2 O) m —R 3   Formula 1:

(In Formula 1, R 1 and R 3 each independently represent alkyl groups having 1 to 4 carbon atoms, R 2 each independently represents alkylene groups having 2 to 3 carbon atoms, and m is an integer of 1 to 4.); and
HO—(R 4 O) n —R 5   Formula 2:

(In Formula 2, R 4 each independently represents alkylene groups having 2 to 3 carbon atoms, R 5 is an alkyl group having 1 to 4 carbon atoms, and n is an integer of 1 to 4.).

First claim

What is claimed is:

1 . A non-aqueous ink jet ink composition comprising:
a glitter pigment; glycol diether represented by Formula 1 shown below and having a flash point of 70° C. or less; and glycol monoether represented by the following formula 2:
R 1 O—(R 2 O) m —R 3   Formula 1:

wherein, in Formula 1, R 1 and R 3 each independently represent alkyl groups having 1 to 4 carbon atoms, R 2 each independently represents alkylene groups having 2 to 3 carbon atoms, and m is an integer of 1 to 4; and
HO—(R 4 O) n —R 5   Formula 2:

wherein, in Formula 2, R 4 each independently represents alkylene groups having 2 to 3 carbon atoms, R 5 is an alkyl group having 1 to 4 carbon atoms, and n is an integer of 1 to 4.

2 . The non-aqueous ink jet ink composition according to claim 1 , wherein a content of the glycol diether is 40 to 90 wt %.

3 . The non-aqueous ink jet ink composition according to claim 1 , wherein a content of the glycol monoether is 20 wt % or less.

4 . The non-aqueous ink jet ink composition according to claim 1 , wherein a content of the glitter pigment is 0.50 to 5.0 wt %.

5 . The non-aqueous ink jet ink composition according to claim 1 , wherein a ratio of the content of the glycol diether to the content of the glycol monoether (Content of the glycol diether/Content of the glycol monoether) is 2.0 or more and less than 20.

6 . The non-aqueous ink jet ink composition according to claim 1 , further comprising cyclic lactone.

7 . The non-aqueous ink jet ink composition according to claim 1 , further comprising cellulose acetate butyrate.

8 . The non-aqueous ink jet ink composition according to claim 1 , wherein
the glitter pigment has a plate-like particle, and a 50% average particle diameter R50 of an equivalent circle diameter determined from an area of an X-Y plane of the plate-like particles is 0.20 to 3.0 μm.

9 . An ink jet recording method comprising:
causing the non-aqueous ink jet ink composition according to claim 1 to adhere to a target recording medium.

10 . An ink jet recording method comprising:
causing the non-aqueous ink jet ink composition according to claim 2 to adhere to a target recording medium.

11 . An ink jet recording method comprising:
causing the non-aqueous ink jet ink composition according to claim 3 to adhere to a target recording medium.

12 . An ink jet recording method comprising:
causing the non-aqueous ink jet ink composition according to claim 4 to adhere to a target recording medium.

13 . An ink jet recording method comprising:
causing the non-aqueous ink jet ink composition according to claim 5 to adhere to a target recording medium.

14 . An ink jet recording method comprising:
causing the non-aqueous ink jet ink composition according to claim 6 to adhere to a target recording medium.

15 . An ink jet recording method comprising:
causing the non-aqueous ink jet ink composition according to claim 7 to adhere to a target recording medium.

16 . An ink jet recording method comprising:
causing the non-aqueous ink jet ink composition according to claim 8 to adhere to a target recording medium.
