(Industrial Application Field) The present invention relates to a coupler that is useful as a raw material for azo dyes, and more specifically, it not only improves the light resistance of the resulting dye itself, but also the light resistance of the material to be colored that is colored by the dye. This invention relates to a coupler that can provide improved azo dyes, especially azo pigments. (Prior Art) Various azo dyes have been known in the past. Among these azo dyes, for example, an azo pigment called a naphthol azo pigment uses a naphthol compound as a coupler. , by coupling it with a diazonium salt or tetrazonium salt of an aromatic primary monoamino or diamine. (Problems to be Solved by the Invention) As the coupling component of the naphthol azo dye, the amino group of β-naphthol, β-oxynaphthoic acid, and aniline or aniline derivative is acylated with β-oxynaphthoic acid. Coupler etc. obtained by this method are known, and the characteristics of azo dyes obtained using these couplers, such as hue, clarity, light resistance, weather resistance,
Solvent resistance etc. are often primarily determined by the structure of the coupler and the structure of the aromatic primary amine coupled to the coupler. Therefore, couplers and/or aromatic primary amines with various structures have been proposed in order to improve various physical properties of the resulting azo dye. Many naphthol-based azo dyes are known. Although these azo dyes are generally characterized by having rich hues and clear tones, none of them are particularly satisfactory in terms of light resistance. Therefore, for example, when these azo dyes are used as colorants for plastics, printing inks, paints, etc., sufficient consideration must be given to the light resistance of the azo dyes used. For example, if an azo dye with insufficient light resistance is used, it will not only cause discoloration or fading of the colored product, but also
A problem has arisen in that the light resistance of the material to be colored itself, such as a coating of plastic, ink, or paint, is also reduced. The above-mentioned problems of discoloration and deterioration of the colored material are
This problem can be solved by using other pigments with excellent light resistance, such as polycyclic pigments, but these pigments with good light resistance are expensive and cannot be used economically for general purposes. In addition, the hue, sharpness, etc. are limited, so it cannot be used satisfactorily. Therefore, when coloring paints, printing inks, plastics, etc. with azo dyes, light stabilizers such as ultraviolet absorbers and deterioration inhibitors are also used, but these light stabilizers Because it is a relatively unstable and low molecular weight organic compound, it is known to cause various problems in resins and binders, and its applications are extremely limited.
It lacked versatility. Therefore, there is a need for the development of a technology that can easily and inexpensively provide azo dyes with excellent light resistance. (Means for Solving the Problems) In response to the above-mentioned demands of the prior art, the inventors of the present invention have conducted extensive research in order to provide an inexpensive azo dye with excellent light resistance. It has been found that the object of the present invention can be achieved by employing a coupler having a specific structure. That is, the present invention is a coupler represented by the following general formula (). However, R 1 and R 2 in the above formula are a hydrogen atom, an alkyl group, or an aryl group, but are not hydrogen atoms at the same time.

By diazotizing or tetrazoting and coupling aromatic primary amines such as those used in the production of aromatic and azo dyes, azo pigments or azo dyes with excellent light resistance can be easily provided. If an aromatic monoamine is used as the group primary amine, a monoazo pigment or a monoazo dye can be obtained, and by using an aromatic diamine as the aromatic primary amine, a disazo pigment or a disazo pigment can be easily provided. The pigment or dye obtained using the coupler of the present invention is itself useful as a pigment or dye with excellent light resistance.One preferable method for using the coupler of the present invention is to use a conventionally known azo dye. This is a method in which an azo pigment containing the coupler of the present invention is prepared in the same manner as the pigment manufacturing method, and this azo pigment is mixed with a conventionally known azo pigment. According to this method, 100 parts by weight of a conventionally known azo pigment is mixed. By adding and mixing at a ratio of about 0.5 to 300 parts by weight, the light resistance of the resulting azo pigment composition and the light resistance of the colored material containing the azo pigment are significantly improved. A preferred method of use is to add and mix the coupler of the present invention into a conventionally known coupler to be used in a proportion accounting for 0.5 to about 50 mol% of the entire coupler to form a mixed coupler. The following is a method of carrying out a coupling reaction according to a conventional method to obtain a pigment composition of an azo pigment containing the coupler of the present invention and an azo pigment not containing the coupler of the present invention. Since the azo pigment contained in the pigment composition is more uniformly distributed in the pigment composition, the effect of improving the light resistance of the azo pigment is even more preferably exhibited. Explain specifically.In addition, in the text, parts or %

Dissolve in 2500 parts of methanol containing 18.4 parts of caustic soda and cool. Separately, 34 parts of Scarlet GG base was diazotized in 150 parts of concentrated sulfuric acid in a conventional manner and neutralized with a buffer to prepare a diazonium salt solution. This diazonium salt solution was placed in a submerging solution cooled to below 0°C.
The mixture was added dropwise over 1 hour, and further stirred at 0 to 5°C for 1 hour to eliminate the diazonium salt. This slurry was heated to the boiling point and aged for 1 hour at the boiling point to obtain a dull bluish red crude pigment. The obtained aqueous press cake of the crude pigment was dispersed in 1700 parts of nitrobenzene and crystallized at 200°C for 2 hours to obtain a bluish-red azo pigment composition. Comparative Example 3 CIPR-144 and the azo pigment composition of Use Example 5 are each mixed with zinc stearate in a weight ratio of pig:Zn-St=6:4 to prepare a dark dry color.
Also, pig this dark dry color: TiO 2 = 1:5
Mix it with white dry color to create light dry color. The obtained dark and light dry colors were mixed with polyethylene resin so that the dark color was 0.1 PHR and the light color was 0.5 PHR, formed into pellets using an extruder, and then plates were made using an injection molding machine. Put the resulting plate through a fade meter,
The ÎE value of each was measured and the results shown in Table 3 below were obtained.
