Abstract

PROBLEM TO BE SOLVED: To eliminate the clogging of an ink discharge head and to further make it possible to reduce the restriction in the selection of coloring materials used for the ink by forming the image by the ink on a recording medium and then visually developing the image with the powder coloring material. SOLUTION: By using an ink jet system for printing by adhering ink droplet to a recording medium in response to print an information signal, colorless adhesive liquid is discharged as ink droplet, a transparent image is previously formed on the medium as a latent image, powder coloring material is brought into contact with the adhesive liquid for forming the latent image and the latent image is visually developed. The developed coloring material does not particularly need the fixing step, but powder coloring material particles adhered to the ink having adhesive properties are immersed or adhered to the medium as they are, and further the adhesive properties of the medium with the coloring material can be raised by using a fixing method or fixing unit used for a normal copying machine or printer.

In this ink jet recording method, a small droplet of ink, which is a recording medium, is ejected and adhered to a recording medium for recording, and a method of generating this ink droplet and the generated small droplet are recorded. It is roughly classified into several methods according to the method for controlling the flight direction. In general, ink droplets are continuously generated regardless of the presence or absence of an information signal, and the continuously generated ink droplets are selectively used according to a print information signal. There is another method called an on-demand type in which ink droplets are ejected and fly.

In the above continuous type, the ink ejection nozzle is ultrasonically vibrated in the ejection direction, and the ink pressurized at a constant pressure is continuously ejected and made into particles. The ink droplet passes through the charging electrode to be charged, and then is deflected in the deflecting electrode that follows. At that time, ink adheres to the recording medium according to the charge amount of the droplet with respect to the information signal voltage,
Other ink droplets are collected by a charge control method, ink is sprayed at high pressure, and the degree of convergence of the ink spray is changed according to the voltage of the control electrode to form an opening to create density gradation. A control method and an ultrasonic vibration element generate ink mist, which is sent by an air flow in the same direction as the feed of the recording medium at approximately the same speed, and the ion current due to corona discharge is passed through the ink mist layer and onto the recording medium. Send to. At that time, there is an ink mist system or the like in which ink mist is attached to ions to carry the ink onto the recording medium.

Each of the above-mentioned various ink jet systems has its own characteristics and has advantages and disadvantages. However, the nozzle clogging caused by the precipitates of dyes, which are the coloring components present in the ink, and the coarse particles of the pigments, is common to any ink jet system. However, many researchers are continuing to study methods to prevent nozzle clogging, and various solutions have been proposed. For example, there is a method of covering the ink discharge nozzle when not in use, etc.
These methods are not fundamental, and after a long pause, nozzle clogging often still occurs,
The fact is that it has not been completely solved.

Further, in consideration of the above-mentioned problem of nozzle clogging, there is a constraint that a material that can be dissolved or easily dispersed in an ink solvent must be selected as a material used as a colorant, and the degree of dispersion thereof. However, in order to prevent the dispersion from clogging the nozzle, a very high degree of dispersion, such as an average particle size of about 0.05 μm, is required. Further, it is necessary to give due consideration to the dispersant so that coarse particles which cause nozzle clogging due to agglomeration of primary particles due to aging do not occur.
