Inkjet recording liquid, inkjet recording device using inkjet recording liquid, and method of using inkjet recording liquid in inkjet recording device
Abstract:
An inkjet recording liquid contains water, an organic solvent, a pigment, and a pigment dispersing resin. An weight-average molecular weight of the pigment dispersing resin exceeds 30000 and is 150000 or less. A mass ratio of the pigment dispersing resin to the pigment in the recording liquid (resin content/pigment content) is 0.1 or more and 1.0 or less. An acid value of the pigment dispersing resin is 160 or more and 240 or less. The inkjet recording liquid is discharged from a recording head of the inkjet recording device. Even when nozzles of the recording head become clogged due to drying or thickening of the inkjet recording liquid, the nozzle clogging can be easily resolved with a purge operation and wiping operation of the recording head by a wipe unit. Thus, it is possible to reduce an overconsumption of the recording liquid due to the foregoing purge operation.
