The present disclosure is drawn to material sets and 3-dimensional printing systems that include a fusing agent. One example of a material set can include a fusing agent and a detailing agent. The fusing agent can include water, a carbon black pigment, and a water-soluble co-solvent in an amount from 20 wt % to 60 wt %. The detailing agent can include water and a black dye. In another example, a material set can include a fusing agent and a thermoplastic polymer powder.

An aqueous ink for ink jet recording includes a coloring material, a water-dispersible polysiloxane-based defoaming agent, a water-soluble silicone-based surfactant, a glycol-based solvent, and resin particles including a non-ionic reactive surfactant in a constituent unit.

Aqueous inkjet ink formulations comprising a solvent including water and a co-solvent, a water soluble or water dispersible polymeric resin and a colorant, and a method for facilitating the use of such an aqueous inkjet ink in an indirect printing system in which the ink is jetted onto a hydrophobic release layer of an intermediate transfer member before having the solvent removed therefrom and being transferred to a substrate, wherein prior to the jetting of the ink the release layer is brought into contact with an aqueous solution of a positively charged polymeric chemical agent. Other aspects are also described.

An ink jet recording ink set of this invention is an ink jet recording ink set containing a dye ink and a pigment ink, in which the dye ink contains a dye in a proportion of 1.4% by mass or more and 5.0% by mass or less based on the total mass of the ink, the pigment ink contains a pigment in a proportion of 4.0% by mass or more and 8.0% by mass or less based on the total mass of the ink, and, when the volume average particle diameter of the pigment ink is defined as 1 and the volume average particle diameter of a mixed liquid in which the dye ink and the pigment ink are mixed in equal amounts in terms of the mass ratio is defined as 2, the following expression (1) is satisfied,

1.002/11.40 (1).

An aqueous ink that enables recording of an image with suppressed feathering and has high ejection stability can be provided. An aqueous ink for ink jet contains a pigment, a polyhydric alcohol derivative and a water-soluble organic solvent. The polyhydric alcohol derivative is a compound in which a proportion of {Y/(X+Y)}100 (%) where X mole(s) of ethylene oxide group(s) and Y mole(s) of propylene oxide group(s) are added to polyhydric alcohol having three or more hydroxy groups is 55% or more to 95% or less. The water-soluble organic solvent includes a first water-soluble organic solvent having a relative dielectric constant of 10.0 or more to 40.0 or less.

An object of the present invention is to provide an ink jet recording method capable of recording a high-quality image in which occurrence of fine unevenness is decreased.

The ink jet recording method is a method of recording an image by ejecting ink from a recording head including an ejection orifice ejecting the ink, an ejection element generating energy for ejecting the ink, and first and second flow paths which communicate between the ejection orifice and the ejection element and in which the ink flows. The ink jet recording method includes an ejection step of ejecting the ink from the ejection orifice; and a flow step of flowing the ink in the first flow path to the second flow path separately from the ejection step, wherein the ink is aqueous ink having a dynamic surface tension of 35 mN/m or more to 48 mN/m or less at 10 milliseconds.
