Problems solved by technology

In addition, compared with silver salt photographs, the recorded matter obtained by the existing inkjet recording method has low fastness (especially ozone resistance), and the recorded matter is exposed to light, humidity, heat, and air in the air for a long time. When exposed to ambient air, etc., there are problems such as deterioration of the colorant on the recorded matter, and color tone changes and fading of the image are likely to occur.
Among the above-mentioned ambient gases, the deterioration of recorded matter caused by ozone is particularly problematic

Embodiment

[0141] Hereinafter, the present invention will be described in more detail using examples and comparative examples. However, the present invention is not limited by the following examples as long as the spirit of the present invention is not exceeded. In addition, unless otherwise specified, the ink components of Examples and Comparative Examples mean "parts by mass".

[0142]

[0143] The compound of the following formula (A) was added and dissolved in water to which sodium carbonate was added, and then diazotized by adding hydrochloric acid and sodium nitrite. A 6-phenylamino-1-hydroxynaphthalene-3-sulfonic acid aqueous solution was added to the diazo cloudy liquid, and dissolved in the presence of sodium carbonate to obtain a reaction liquid (A). Next, 2-sulfamic acid was dissolved in the presence of sodium hydroxide, and hydrochloric acid and sodium nitrite were added to carry out diazotization. Next, 6-amino-1-hydroxynaphthalene-3-sulfonic acid was dissolved in the pre...

Description

[0001] This application is a divisional application of an application with a filing date of August 30, 2005, an application number of 200580029083.6, and an invention title of "inkjet ink, manufacturing method of inkjet ink, inkjet recording method, and ink cartridge". technical field [0002] The present invention relates to an inkjet ink, a method for producing the inkjet ink, an inkjet recording method, and an ink cartridge. Background technique [0003] The inkjet recording method is a recording method for forming an image by applying small ink droplets on recording media such as plain paper and glossy media, and is rapidly spreading and developing as its price becomes lower and the recording speed increases. In addition, in addition to the continuous improvement of the quality of recorded images, with the rapid spread of digital cameras, users have requested to output recorded objects comparable to silver halide photographs. [0004] As the necessary requirements for th...
