Abstract
Provided is a non-aqueous maintenance liquid for an active energy ray-curable inkjet ink which can be used as a cleaning liquid for removing the inkjet ink and as a preserving liquid to fill the head when the printer is not in operation. The non-aqueous maintenance liquid for an active energy ray-curable inkjet ink of the present invention comprises a main liquid component, a pigment dispersant resin, and a surface control agent, wherein the main liquid component is an organic solvent and/or an active energy ray-curable compound, and the amount of the surface control agent is 0.01 to 10% by weight in 100% by weight of the maintenance liquid.
Claims17
A maintenance liquid comprising
- an active energy ray-curable compound in an amount of 70% by weight or more in 100% by weight of the maintenance liquid, wherein the active energy ray-curable compound is dipropylene glycol diacrylate,
- a poly ether modified dimethylsiloxane silicone-based surface control agent in an amount of 0.2 to 10% by weight in 100% by weight of the maintenance liquid, and
- a polyethyleneimine-based pigment dispersant resin
- in an amount of 0.02 to 5% by weight in 100% by weight of the maintenance liquid, and
- wherein said maintenance liquid does not comprise a photopolymerization initiator, a coloring agent, a dye, or a pigment.
A maintenance liquid comprising:
- an active energy ray-curable compound in an amount of 70% by weight or more in 100% by weight of the maintenance liquid, wherein the active energy ray-curable compound is dipropylene glycol diacrylate,
- a polyether modified dimethylsiloxane silicone-based surface control agent in an amount of 0.2 to 10% by weight in 100% by weight of the maintenance liquid, and
- a pigment dispersant resin
- selected from the group consisting of a basic dispersant resin having a basic functional group, a basic dispersant resin having a urethane skeleton, and a polyalkyleneimine-based pigment dispersant resin in an amount of 0.02 to 5% by weight in 100% by weight of the maintenance liquid, and
- wherein said maintenance liquid does not comprise a photopolymerization initiator.
