There are provided a pearl culture material containing at least one selected from the group consisting of a pearl nucleus and a mantle, and the at least one selected from the group consisting of a pearl nucleus and a mantle contains a protein having 10 EU/g or less of an endotoxin amount, a nucleus insertion method, and a pearl culture material composition.

Pearl culture material, nucleus insertion method, and pearl culture material composition

The invention provides an ink-jet recording ink set including at least one first liquid A for at least forming an image and at least one second liquid B having a different composition from the composition of the first liquid A, wherein the first liquid A contains at least a polymer having a heterocyclic residue for forming a colorant, and a pigment, as well as an ink-jet recording method using the ink set.

Ink-jet recording ink set and ink-jet recording method

The image forming apparatus includes: an intermediate transfer body; a liquid adhesion device which provides a first liquid having a viscosity not less than 15 mPa&#xb7;s and not greater than 300 mPa&#xb7;s at 25&#xb0; C, on the intermediate transfer body; a droplet ejection device which ejects a second liquid containing a coloring material onto a region of the intermediate transfer body where the first liquid is provided by the liquid adhesion device, in a state where the first liquid on the intermediate transfer body has a thickness not less than 1.6 &#x3bc;m; a viscosity raising device which raises a viscosity of the second liquid on the intermediate transfer body; and a transfer device which transfers an image including dots of the second liquid formed on the intermediate transfer body, onto a recording medium.

Image forming apparatus and image forming method with decreased image transfer disturbance

The image forming method for forming a desired image on a recording medium, includes the steps of: applying a first liquid on the recording medium, the first liquid containing no coloring material and having a dynamic surface tension at a surface age of 0.1 seconds measured at 25&#xb0; C. of &#x3b3;(0.1 s); and then depositing droplets of a second liquid on a region of the recording medium where the first liquid has a form of a liquid film, the second liquid containing coloring material and having a dynamic surface tension at a surface age of 0.1 seconds measured at 25&#xb0; C. of &#x3b3;(0.1 s) that is greater than &#x3b3;(0.1 s).

Image forming method and image forming apparatus

The inkjet recording apparatus which forms an image on a recording medium by applying a first liquid containing coloring material and a second liquid containing no coloring material or the coloring material of not greater than 0.1 wt %, on the recording medium, includes: a liquid application device which applies the second liquid on the recording medium and then ejects droplets of the first liquid toward the second liquid applied on the recording medium; and an electron beam irradiation device which radiates an electron beam on the first liquid and the second liquid on the recording medium, wherein: at least one of the first liquid and the second liquid contains a polymerizable compound which is polymerized when irradiated with the electron beam; and the electron beam irradiation device radiates the electron beam at an acceleration voltage of 40 kV through 60 kV.
