Definitions
- the present invention relates to a novel azodiether or a salt thereof, an ink composition containing the same, and a colored body thereof.
- a recording method using an inkjet printer which is one of the representative methods among various color recording methods, generates small ink droplets and adheres them to various recording materials (paper, film, cloth, etc.). This is to record. This method is quiet because there is no contact between the recording head and the material to be recorded, and produces little sound. In addition, it has been rapidly spreading in recent years because of its features of downsizing and easy high-speed driving. Growth is expected.
- aqueous inks in which a water-soluble dye is dissolved in an aqueous medium have been used as inks for fountain pens, felt pens, and the like, and ink jet recording inks. Generally, a water-soluble organic solvent is added to prevent clogging of the ink. With these conventional inks, it is necessary to provide a printed image with sufficient density and to prevent clogging of the pen tip and nozzle.
- images to be formed are required to have image fastness such as water fastness, light fastness, ozone gas fastness, and moisture fastness.
- Ozone gas resistance is a force also called ozone resistance or gas resistance, etc.
- Ozone gas having an oxidizing effect existing in the air acts on a dye in a recording paper to cause a printed image to discolor and fade.
- Resistance to the phenomenon of In addition to ozone gas, oxidizing gases that have this type of action include NOx and SOx.
- Oxon gas power among these oxidizing gases Further promotes the discoloration phenomenon of inkjet-recorded images It is considered to be the main causative substance.
- the ink-receiving layer provided on the surface of photographic quality ink jet paper is made of a white inorganic material or the like in order to accelerate ink drying and reduce blurring in high image quality. Discoloration and fading due to ozone gas are remarkably observed on such recording paper, which often uses a porous material.
- the ink composition used for ink jet recording which will expand the field of use of a printing method using ink, and a colored body colored thereby will have water resistance, light resistance, and light resistance. Further improvements in moisture and ozone gas resistance are strongly demanded.
- Inks of various hues have been prepared with various dye strengths, of which black ink is an important ink used for both mono-color and full-color images.
- Many products have been proposed as dyes for these black inks to date, and we have been able to provide products that fully satisfy the requirements of the power plant!
- Many dyes have been proposed! Disazo dyes, which have too low a hue (become reddish black), poor color rendering (the property of changing the hue depending on the light source), poor water resistance and moisture resistance There are problems such as bad and insufficient ozone gas resistance.
- azo-containing dyes that have been proposed have problems such as containing metal ions, giving sufficient consideration to human safety and the environment, and insufficient ozone gas resistance.
