Abstract

A recording method of the present disclosure, which is a recording method of performing recording on a recording medium by using a recording device including an ink jet head, includes ejecting a composition for ink jet from the ink jet head, in which the composition for ink jet contains a metal pigment, the metal pigment is formed of a plurality of scaly metal particles, the ink jet head includes a circulation flow path for circulating the composition for ink jet, and an average thickness of the metal particles determined by atomic force microscopy is 19 nm or less.

First claim

What is claimed is:

1 . A recording method of performing recording on a recording medium by using a recording device including an ink jet head, the recording method comprising:
ejecting a composition for ink jet from the ink jet head, wherein the composition for ink jet contains a metal pigment, the metal pigment is formed of a plurality of metal particles having a scale shape, the ink jet head includes a circulation flow path for circulating the composition for ink jet, and an average thickness of the metal particles determined by atomic force microscopy is 19 nm or less.

2 . The recording method according to claim 1 , wherein
a content of the metal particles in the composition for ink jet is 0.2% by mass or more and 4.0% by mass or less.

3 . The recording method according to claim 1 , wherein
the metal particles are formed of a material containing aluminum or an aluminum alloy.

4 . The recording method according to claim 1 , wherein
the metal particles are surface-treated with a phosphorus compound or a silicon compound.

5 . The recording method according to claim 1 , wherein
a volume average particle size D50 of the metal particles is 0.20 μm or more and 1.00 μm or less.

6 . The recording method according to claim 1 , wherein
an average aspect ratio of the metal particles, which is a ratio of a volume average particle size D50 of the metal particles to the average thickness of the metal particles determined by the atomic force microscopy, is 20 or more and 2,000 or less.

7 . The recording method according to claim 1 , wherein
the average thickness of the metal particles determined by the atomic force microscopy is 5 nm or more and 19 nm or less.

8 . The recording method according to claim 1 , wherein
the composition for ink jet is a solvent-based ink.

9 . The recording method according to claim 1 , wherein
a ratio of a circulation flow rate of the composition for ink jet flowing through the circulation flow path to a maximum ejection amount of the ink jet head is 0.50 or more and 15 or less.

10 . A recording device comprising:
an ink jet head, wherein the ink jet head includes a circulation flow path for circulating a composition for ink jet, and the recording method according to claim 1 is performed.
