preparation example Construction

[0211] Because the preparation method of its hydrophobic group cationic self-dispersing carbon black is illustrated by the method of introducing an N-ethylpyridine group into a kind of pigment:

[0212] Carbon black was treated with 3-amino-N-ethylpyridine bromide.

[0213] Because the pigment that is cationic by introducing a hydrophobic group into the surface of the pigment in the above-mentioned manner shows excellent dispersibility in water due to the repulsion between ions, even when it is contained in an aqueous ink without adding any dispersant or In the case of analogues, a stable dispersion state can still be maintained. Carbon black is particularly suitable as pigment.

[0214] On the other hand, in order to obtain an ink having desired physical properties, a surfactant, an antifoaming agent, or a preservative may be added to the ink in addition to the above-mentioned ingredients. The ink may contain a commercially available water-soluble material.

example 1 to example 8

[0352] In Examples 1 to 8, a color image was formed on PPC paper (manufactured by Canon Corporation) using a combination of liquid components A to D and ink sets 1 and 2. For printing, an inkjet recording apparatus as shown in FIG. 1 equipped with 5 recording heads as shown in FIG. 3 was used. At that time, the liquid component is applied to the recording paper before the ink is applied.

[0353] Actually, printing is done with 3-pass fine printing, and the printing area is scanned three times. At this time, each liquid component is applied to a position corresponding to one pixel, and any one of yellow, magenta, cyan, and black inks is applied to each pixel. That is, the logic of the print data for yellow, magenta, cyan, and black and the data applied as liquid components are employed in each printing. The type of fine mask used for fine printing is not particularly limited, and any known technique may be used. A detailed description is therefore omitted.

Abstract

The invention relates to a liquid composition measurement method. One embodiment of the method comprises the steps of: i) subjecting a liquid composition containing fine particles and a solvent to the following pretreatment steps (a) to (c) to form an agglomerate of fine particles: (a) evaporating the solvent of the liquid composition at 120 DEG C for 10 yours in atmosphere, and drying the liquid composition; (b) burning the dried liquid composition resulting from the pretreatment step (a) at 700 DEG C after raising temperature from 120 DEG C to 700 DEG C over one hour; (c) cooling a burned product obtained in the pretreatment step (b) to room temperature, powdering the burned product to obtain agglomerates of the fine particle; and ii) vacuum degassing the agglomerates at 120 DEG C for 8 hours, and measuring physical properties of pores of the agglomerates by a nitrogen adsorption and desorption method.

Description

technical field [0001] The present invention relates to a technique for obtaining color images excellent in coloring and coloring uniformity, and more particularly to a method for determining a liquid composition most suitable for inkjet recording technology, a combination of such liquids and an ink set using such a liquid composition, a method of forming a colored portion on a recording medium, and an inkjet recording apparatus. Background technique [0002] The inkjet recording method is to perform recording by jetting ink to apply the ink on a recording medium such as paper. It is easy to realize a high-density, porous head to form high-resolution and high-quality images at high speed by using an inkjet recording method, where thermal energy is applied to the ink by using an electrothermal converter as an ejection energy supply part, and the ink Bubbles are generated in the bubbles, and ink droplets are ejected by the action of the bubbles, as disclosed in Japanese Paten...
