Ink jet recording method and ink set
An ink jet recording method includes a reaction liquid attaching process of attaching a reaction liquid containing a coagulant having solubility of 120 g or less in 100 g of water as a coagulant which coagulates components of an ink composition to a low absorbent recording medium or a non-absorbent recording medium to form a first recorded region, and an ink composition attaching process of attaching the ink composition containing water and a resin having a percentage of water absorption of 0.3% or less to at least one part of the first recorded region to form a second recorded region.
1. An ink jet recording method comprising:
attaching by ink jet coating a reactin liquid to a low absorbent recording medium or non-absorbent recording medium to form a first recorded region, the reaction liquid containing a coagulant having solubility of 120 g or less in 100 g of water as a coagulant which coagulates components of an ink composition, and
attaching the ink composition containing water and a resin having a percentage of water absorption of 0.3% or less to at least one part of the first recorded region to form a second recorded region,
wherein the attaching of the ink composition includes:
attaching a first ink composition to at least one part of the first recorded region to form the second recorded region, the first ink composition being a color ink composition that contains water, a coloring material, and the resin having a percentage of water absorption of 0.3% or less, a content of the resin having a percentage of water absorption of 0.3% or less being less than 5% by mass, and
attaching a second ink composition such that the second ink composition overlaps the first ink composition,
wherein the second ink composition is a clear ink composition that contains water and the resin having a percentage of water absorption of 0.3% or less, a content of the resin having a percentage of water absorption of 0.3% or less in the second ink composition is 10% by mass or less, and
the resins having a percentage of water absorption of 0.3% or less contained in each of the first and second ink compositions are a polyolefin-based resin.
2. The ink jet recording method according to claim 1 , wherein
the resin contains resin fine particles.
3. The ink jet recording method according to claim 1 , wherein
a maximum application amount of the resin in the second recorded region is 0.050 to 0.45 mg/inch 2 .
4. The ink jet recording method according to claim 1 , wherein
a maximum application amount of the coagulant in the first recorded region is 0.0030 to 0.15 mg/inch 2 .
5. The ink jet recording method according to claim 1 , wherein
the low absorbent recording medium or the non-absorbent recording medium is a film.
6. The ink jet recording method according to claim 1 , wherein
the reaction liquid contains at least either a polyvalent metallic salt or organic acid as the coagulant.
7. The ink jet recording method of claim 1 , wherein the resin having the percentage of water absorption of 0.3% or less is one of a polyethylene resin and a polypropylene resin.
8. The inkjet recording method of claim 1 , wherein the recording medium is a non-absorbent recording medium.
9. The ink jet recording method of claim 1 , wherein the content of the resin having a percentage of water absorption of 0.3% or less is 3% by mass or less with respect to the total mass of the first ink composition.
10. The inkjet recording method of claim 1 , wherein the content of the resin having a percentage of water absorption of 0.3% or less is 0.5% to 10% by mass with respect to the total mass of the second ink composition.
11. The inkjet recording method of claim 1 , wherein a maximum amount of the resin having a percentage of water absorption of 0.3% or less in the second recorded region is 0.05 mg/inch 2 .
