A thixomolding material includes: a metal body containing magnesium(Mg) as a primary component; a plurality of coating particles provided at a front surface of the metal body and having an average particle diameter equal to or less than 100 μm, the plurality of coating particles being made of an inorganic material differing from the metal body; and an interposed particle interposed between the metal body and the coating particles and having an average particle diameter smaller than the coating particle, the interposed particle being made of an inorganic oxide.

Thixomolding material and method of manufacturing thixomolding material

An ink jet ink composition includes: a colorant; silica particles; 1-(2-hydroxyethyl)-2-pyrrolidone; and water, and the silica particles have in a TEM image thereof, a Di (diameter of the maximum inscribed circle)/Dc (diameter of the minimum circumscribed circle) of 0.7 or more.

Ink jet ink composition and recording method

Provided is a thixomolding material including a metal body that contains Mg as a main component, and a coating portion that is adhered to a surface of the metal body via a binder and contains C particles containing C as a main component. A mass fraction of the C particles in a total mass of the metal body and the C particles is 5.0 mass % or more and 40.0 mass % or less. The binder may contain waxes. The C particles may be graphite particles.

Thixomolding material

A thixomolding material includes: a metal body that contains Mg as a main component; and a coating portion that is adhered to a surface of the metal body via a binder and contains SiC particles containing SiC as a main component. A mass fraction of the SiC particles in a total mass of the metal body and the SiC particles is 2.0 mass % or more and 40.0 mass % or less. The binder may contain waxes. A content of the binder may be 0.001 mass % or more and 0.200 mass % or less.

Ink for ink jet recording, ink jet recording apparatus, and ink jet recording method

An aqueous ink jet ink composition contains pigment particles, inorganic oxide particles, and resin particles. The content of the inorganic oxide particles is 1.0% to 10.0% relative to the total mass of the ink composition. The ink composition satisfies the following relationship:

Aqueous ink jet ink composition and ink jet printing method

An ink jet printing ink composition contains a pigment, colloidal silica, trimethylglycine, and water, and in which a content of the colloidal silica is lower than or equal to a content of the trimethylglycine.

Ink jet printing ink composition and ink jet printing method

An ink composition contains pigment particles, inorganic oxide particles, and a lactam solvent. The content of the inorganic oxide particles is 5.0% to 10.0% relative to the total mass of the ink composition. The ink composition satisfies the following relationship:

An ink for ink jet recording according to an embodiment is an ink for ink jet recording containing pigment, colloidal silica, and amino acid.

An ink jet recording apparatus includes a line head including a region of nozzles that are formed in an intersecting direction intersecting a transport direction of a recording medium and eject an ink, the region covering a printing region of the recording medium in the intersecting direction, a drying unit that dries the recording medium, a transport unit that transports the recording medium, and a control unit. The ink contains colloidal silica, and the control unit controls the drying unit and the transport unit such that drying of the ink is started within 0.4 second after the ink is attached to the recording medium.
