Problems solved by technology

[0006] However, according to these technologies, although improvement effects have been obtained to some extent in terms of the miniaturization and aggregation of pigment particles, products that can meet the requirements of inks and the like in which finer pigment particles are dispersed have not yet been obtained.

manufacture example 1

[0081] In 100 parts of water, add 7.3 parts of cyanuric chloride (Cyanuric chloride) and 6.8 parts of p-aminobenzenesulfonic acid (trade name: ASASulfanilic acid, Sugai Chemical IND.CO ., LTD. production), reacted at 20°C for 1 hour. Next, 10 parts of 4,4'-methylene-bis-2,6-xylaniline (trade name: KAYABOND C-200S, produced by Nippon Kayaku) in an amount that reacts with one Cl of the reactant was added, React at 70°C for 1 hour. After the obtained reactant was filtered and the residue was washed with water, it was left to stand overnight in a thermostat at 80° C., and dried to obtain 17.0 parts of a triazine compound represented by the above formula (10).

manufacture example 2

[0083] Except having added 3.4 parts of p-aminobenzenesulfonic acid instead of 6.8 parts of p-aminobenzenesulfonic acid, it carried out similarly to manufacture example 1, and obtained 14.8 parts of triazine compounds represented by said formula (11).

manufacture example 3

[0085] Add 4.3 parts of p-phenylenediamine (trade name: p-phenylene diamine, produced by Wako Pure Chemical Industries) to replace 10 parts of 4,4'-methylene-two-2,6-xylidine, in addition, carry out and In the same manner as in Production Example 1, 12.5 parts of the triazine compound represented by the above formula (12) were obtained.

Abstract

The present invention provides a fine pigment composition which comprises organic pigment with extraordinarily small particle diameter and has remarkably restrained agglutination. The invention also provides a manufacturing method which can easily prepare the fine pigment composition. The fine pigment composition comprises triazine represented by a formula (1) and the organic pigment. In the formula (1), A represents an acid group or a base group; B represents -OH, -Cl, an acid group or a base group; and D represents -H, -Cl, -OH or aromatic amine residues.

Description

technical field [0001] The present invention relates to a fine pigment composition containing a fine organic pigment and a method for producing the same. Background technique [0002] In printing inks or paints, such as inks for inkjet printers and inks for color filters, by dispersing pigments in a fine state, it is possible to exhibit high tinting strength, and to make printed matter or painted products have clear hues, gloss, etc. Sex, and make the coating film such as color filter have the adaptability such as chromaticity, contrast (contrast). In recent years, inks and the like obtained by dispersing finer pigment particles have been strongly desired in view of market demands for high-quality printed matter and the like. [0003] Therefore, in order to make the pigment finer, further reduction in the particle diameter of the primary particle of the once-obtained pigment by means of a salt mill or the like is widely carried out. [0004] However, pigment particles temp...
