Inkjet ink, inkjet ink set, ink stored container, and inkjet recording method

1. An inkjet ink set comprising:

a first ink comprising:

a resin containing a resin (1) having a structural unit represented by the following general formula (1):

—(CH 2 CH 2 O) n —  general formula (1)

where n represents an integer of 5 to 100; and

a polyvalent metal ion,

wherein a dried film obtained by drying the resin has a storage modulus of 1.0=10 8 Pa or lower in a dynamic viscoelasticity measurement at 25 degrees C.; and

a second ink containing a colorant,

wherein a dried film obtained by drying the second ink has a storage modulus of 7.0×10 8 Pa or lower in the dynamic viscoelasticity measurement at 25 degrees C.

2. The inkjet ink set according to claim 1 , wherein a content of the structural unit represented by the general formula (1) in the resin (1) is 5% by mass to 60% by mass.

3. The inkjet ink set according to claim 1 , wherein the dried film obtained by drying the resin has a storage modulus of 3.0×10 8 Pa or lower in a dynamic viscoelasticity measurement at −20 degrees C.

4. The inkjet ink set according to claim 1 , wherein the resin (1) having the structural unit represented by the general formula (1) is a polyurethane resin.

5. The inkjet ink set according to claim 1 , further comprising a silicone surfactant.

6. The inkjet ink set according to claim 1 , wherein the second ink further contains a polyurethane resin.

7. An inkjet recording method, comprising:

discharging said first inkjet ink of said inkjet ink set according to claim 1 from a nozzle of a recording head;

applying said first inkjet ink onto a recording medium;

discharging said second inkjet ink of said inkjet ink set according to claim 1 from a nozzle of a recording head; and

applying said second inkjet ink onto said recording medium.

8. The inkjet recording method according to claim 7 , wherein the recording medium comprises at least one of a fabric or a plastic film.
