- the present invention relates to an oil-based white ink for ink jet recording (hereinafter simply referred to as “white ink” or “ink
- the present invention relates to an oil-based white ink for ink-jet recording having excellent stable discharge properties and excellent recoverability after standing for a long time.
- ink jet recording methods inject ink droplets from a print head or spray nozzle toward a recording material at a high speed in response to an electric signal from a computer or the like, and an ink receiving layer of the recording material. It is a recording method that prints on the screen.
- the above-described ink jet recording method is widely used for copying, facsimile, posters, displays, and the like because it can record at high speed with less noise.
- the ink used in these ink jet recording methods can maintain a sufficient density for a long period of time when an image that does not change with time is formed, and the image printed on the recording material is excellent. It is required to have document reproducibility and sufficient density.
- the ink used is required not to be clogged by the head nozzle or to clog the filtration filter that passes through until reaching the ink cartridge force head. Therefore, it is necessary to adjust the ink properties such as density, viscosity, particle size, and concentration of the ink.
- the above ink is generally composed of a dye or pigment colorant, a dispersant or solvent for dispersing them, and an additive as required.
- white ink for ink jet prints on a black or transparent recording material with low lightness to obtain a printed material with good visibility, and is also effective for marking various products.
- printing on the above recording material with a colored ink other than white ink printing cannot be clearly reproduced due to the influence of the underlying color. For this reason, it is required to perform background printing with a white ink having sufficient concealment to the background to conceal the empty background and to print with other colored ink on the white background.
- the above white ink uses a titanium oxide pigment as a colorant
- the white ink using a conventional titanium oxide pigment is precipitated due to the specific gravity of the pigment particles and the solvent used during storage, especially when an alcohol solvent is used. Aggregation reduces the redispersibility of the titanium oxide pigment.
- Patent Document 1 a white pigment composition
- Patent Document 1 a white oxide precipitated by dispersing an alumina-treated titanium oxide pigment in an alcohol solvent using an acrylic resin having a carboxyl group as a dispersant.
- the pigment can be used as it is without redispersion of the precipitated pigment in the ink in actual work.
- titanium oxide pigments are used as white pigments, the aggregation of the ink pigments during ink storage progresses quickly. There are cases where the ejection is not stable, the printer's nozzle is clogged, or, in the worst case, the printer head needs to be replaced.
