Description
本発明は、水溶性アゾ染料及びそれを含む染料組成物に関する。さらに詳細には、本発明は、ジスアゾ化合物、その銅錯体である銅化ジスアゾ化合物若しくはそれらの塩、並びに、銅化ジスアゾ化合物若しくはその塩及び他の染料化合物若しくはその塩を含む染料組成物に関する。また、本発明は、それらの水溶性アゾ染料又は染料組成物を用いる染色方法に関する。 The present invention relates to a water-soluble azo dye and a dye composition containing the same. More specifically, the present invention relates to a disazo compound, a copperated disazo compound that is a copper complex thereof, or a salt thereof, and a dye composition that includes a copperated disazo compound or a salt thereof and another dye compound or a salt thereof. The present invention also relates to a dyeing method using these water-soluble azo dyes or dye compositions.
従来、製紙材料を含むセルロース系繊維材を堅牢な青色から紫色に染める染料としてはC.I.Direct Blue 15、C.I.Direct Blue 200、C.I.Direct Blue 202、C.I.Direct Blue 203等がよく知られている。これらの染料は、綿、レーヨンの染料として衣料品の染色や、紙パルプの染色用として製紙業界において多用されている。また、当該染料は、一般的に、主原料としてジアニシジンを用いて製造されている。 Conventionally, as a dye for dyeing a cellulosic fiber material containing a papermaking material from a solid blue color to a purple color, C.I. I. Direct Blue 15, C.I. I. Direct Blue 200, C.I. I. Direct Blue 202, C.I. I. Direct Blue 203 and the like are well known. These dyes are frequently used in the paper industry for dyeing clothing and dyeing paper pulp as dyes for cotton and rayon. Moreover, the said dye is generally manufactured using dianisidine as a main raw material.
特に、製紙材料の染色分野において、微量の青色染料や紫色染料にて染色することによって、その用紙を光学的な純白よりさらに白く見せる技術がある。この染色方法をブルーイング又は青みづけといい、一般的には青色から紫色の直接染料が用いられている。ブルーイング用染料には、染料やその染料溶液が保存時に安定であること、染色後の色が鮮明で光等に対する堅牢度がよいこと等の特性が要求される。従来、ブルーイング用染料としては、原料にジアニシジンを用いて製造される青色染料が、鮮明色であることから多用されてきた。 In particular, in the field of dyeing papermaking materials, there is a technique for making the paper appear whiter than optically pure white by dyeing with a small amount of blue dye or purple dye. This dyeing method is called bluing or bluing, and generally a blue to purple direct dye is used. The dye for bluing is required to have characteristics such that the dye and the dye solution are stable during storage, the dyed color is clear and fastness to light is good. Conventionally, as a dye for bluing, a blue dye produced using dianisidine as a raw material has been frequently used because of its clear color.
しかし、これらの染料に共通する問題点として、主原料として使用されているジアニシジンが、日本国の労働安全衛生法における特定化学物質第一類(有害性が高く労働者に重度の健康障害を生じるおそれがある化学物質)に該当することである。そのため、各染料の製造工程ではジアニシジンの使用について法規制を強く受けることになり、極めて厳重な防護設備の下で作業する等の安全衛生管理面及び生産効率向上にとって制約要因となっている。 However, a common problem with these dyes is that dianisidine, which is used as the main raw material, is the first class of specified chemical substances in Japan's Industrial Safety and Health Act (which is highly harmful and causes severe health problems for workers. Chemical substances that may have a risk). For this reason, the production process of each dye is strongly regulated by the use of dianisidine, which is a limiting factor for improving safety and health management such as working under extremely strict protective equipment and improving production efficiency.
ジアニシジン以外の原料から製造される青色から紫色の染料又は直接染料としては、例えば、C.I.Direct Blue 67、C.I.Direct Blue 78、C.I.Direct Blue 106、C.I.Direct Blue 108、C.I.Direct Violet 9、C.I.Direct Violet 35、C.I.Direct Violet 51等が挙げられる。しかし、いずれの染料も、前記のジアニシジン系の染料に比べて、明らかに鮮明性、染着性、堅牢性、耐熱性等の染色性能が劣っている。従って、これらの染料もまた、製紙材料を含むセルロース系繊維材を堅牢な青色から紫色に染める染料としても、ブルーイング用染料としても適切ではない。 Examples of blue to purple dyes or direct dyes produced from raw materials other than dianisidine include C.I. I. Direct Blue 67, C.I. I. Direct Blue 78, C.I. I. Direct Blue 106, C.I. I. Direct Blue 108, C.I. I. Direct Violet 9, C.I. I. Direct Violet 35, C.I. I. Direct Violet 51 etc. are mentioned. However, all the dyes are clearly inferior in dyeing performance such as sharpness, dyeability, fastness, heat resistance and the like as compared with the above-mentioned dianisidine dyes. Therefore, these dyes are also not suitable as dyes for dyeing a cellulosic fiber material containing papermaking materials from a solid blue color to a purple color or as a dye for bluing.
従って、これらの既存の染料以外の鮮明で堅牢度のよい青色から紫色の染料又は直接染料が、染料製造業界、製紙業界及び染色業界にとって永年強く望まれている。しかし、現在までこれらの要求を全て満足する優れた染料は、いまだに得られていない。 Accordingly, vivid and fast-dyed blue to purple dyes or direct dyes other than these existing dyes have been strongly desired for many years by the dye manufacturing industry, paper industry and dyeing industry. However, excellent dyes that satisfy all these requirements have not yet been obtained.
例えば、特公昭64−5623号公報(特許文献1)、特開平7−18192号公報(特許文献2)には、ジアニシジンを使用しない青色染料として下記式(5)で表される染料化合物が記載されている。 For example, JP-B-64-5623 (Patent Document 1) and JP-A-7-18192 (Patent Document 2) describe a dye compound represented by the following formula (5) as a blue dye not using dianisidine. Has been.
この染料を用いることによって、製紙材料を均染性良く鮮明な青色に染めることが可能である。しかし、この染料は、色相が緑みであるため、中庸な赤みな青色が得られず用途が限定される。加えて、染着性もカラーバリューも不良であり、また単独ではブルーイング用の適性が低いという不都合を有している。 By using this dye, it is possible to dye the papermaking material into a clear blue with good levelness. However, since the hue of this dye is greenish, no medium blue color is obtained, and its use is limited. In addition, both the dyeability and the color value are poor, and there is a disadvantage that the suitability for bluing alone is low.
また、直接染料として用いられる染料組成物は、所望の色彩への染色性能に加え、実際の染色作業性の観点から、染料溶液の安定性が高いこと、すなわち、保存時にある程度の時間が経過しても結晶が析出し難く、色調の変化が起こらないことが要求される。しかし、ブルーイング用として適度な赤みの青色を得ることが可能であると共に、保存時の安定性が優れた直接染料を含む染料組成物は、今まで得られていない。 In addition, dye compositions used as direct dyes have high dye solution stability from the viewpoint of actual dyeing workability in addition to dyeing performance to a desired color, that is, a certain amount of time has elapsed during storage. However, it is required that the crystals hardly precipitate and the color tone does not change. However, a dye composition containing a direct dye that can obtain an appropriate reddish blue color for bluing and has excellent stability during storage has not been obtained so far.
なお、特開昭59−140263号公報(特許文献3)には、染料組成物に使用されるジスアゾ化合物として、下記式(6)で表される化合物が記載されている。しかし、当該文献には、カルボキシル基で置換されたフェニル基を有するジスアゾ化合物は、記載されていない。 JP-A-59-140263 (Patent Document 3) describes a compound represented by the following formula (6) as a disazo compound used in a dye composition. However, this document does not describe a disazo compound having a phenyl group substituted with a carboxyl group.
本発明の目的の一つは、日本国の労働安全衛生法における特定化学物質第一類に該当するジアニシジンを使用することなく、染着性、堅牢性、耐熱性、鮮明性等を満足させる染料、及びそれを用いた染色方法を提供することである。
本発明の他の目的は、セルロース系繊維材、中でもパルプ等の製紙材料を堅牢、高濃度で、より中庸な青色から紫色に染色し、且つ、安全衛生、省資源及び環境汚染の面で人や地球に優しい染料、及びそれを用いた染色方法を提供することである。
本発明のさらなる他の目的は、ジアニシジンを原料として用いない青色直接染料と紫色直接染料の組み合わせにより、ブルーイング用染料に適した、鮮明で染色特性のよい赤みの青色染料組成物と、それを用いた染色方法を提供することである。One of the objects of the present invention is a dye that satisfies dyeing property, fastness, heat resistance, sharpness, etc. without using dianisidine that falls under the category 1 of the specified chemical substances in the Japanese Industrial Safety and Health Act. And a staining method using the same.
Another object of the present invention is to dye cellulosic fiber materials, especially pulp and other papermaking materials, in a robust, high concentration, more neutral blue to purple color, and in terms of safety and health, resource saving and environmental pollution. And an earth-friendly dye and a dyeing method using the same.
Still another object of the present invention is to provide a reddish blue dye composition which is suitable for bluing dyes and has good dyeing characteristics by combining a blue direct dye and a purple direct dye that do not use dianisidine as a raw material. It is to provide the staining method used.

染色物の製造
実施例8、比較例6あるいは比較例7の染料水溶液0.05部を水1000部に溶解し、染浴を調製した。この染浴に叩解クラフトパルプ300部(絶乾パルプ30部、叩解度35SR)を加えて、室温で15分間攪拌した後、ロジンサイズ(30%水溶液)1部を加え、さらに10分間攪拌した後に結晶硫酸アルミニウム3部を加え、20分間攪拌した。染色したパルプを抄紙すると、鮮明な赤みの青色紙が得られた。Production of dyed product 0.05 part of the dye aqueous solution of Example 8, Comparative Example 6 or Comparative Example 7 was dissolved in 1000 parts of water to prepare a dye bath. After adding 300 parts of beaten kraft pulp (30 parts of absolutely dry pulp, degree of beating 35SR) to this dye bath and stirring for 15 minutes at room temperature, 1 part of rosin size (30% aqueous solution) was added and stirred for another 10 minutes. 3 parts of crystalline aluminum sulfate was added and stirred for 20 minutes. When the dyed pulp was made, a clear reddish blue paper was obtained.
試験例3
各染料水溶液とその染色物について、溶液安定性、色調、耐光堅牢度を試験し、その評価結果を以下に示した。
染料水溶液の溶液安定性は、染料水溶液を室温で保管し結晶の析出を目視で評価した。
染色物の耐光堅牢度は、上記同様に評価した。Test example 3
Each aqueous dye solution and its dyed product were tested for solution stability, color tone, and light fastness, and the evaluation results are shown below.
The solution stability of the aqueous dye solution was evaluated by visual observation of crystal precipitation while the aqueous dye solution was stored at room temperature.
The light fastness of the dyed product was evaluated in the same manner as described above.
比較例7の染料に関する評価結果から明らかなように、現在使われているジアニシジンを原料としない青色直接染料は、製紙分野のブルーイング用染料としては耐光堅牢度や溶液安定性が不良であった。一方、実施例8の染料の結果から、本発明の2種の直接染料を配合した染料組成物はジアニシジンを原料としていないが、ジアニシジンを原料とする染料を用いた比較例6と同じく赤みの青色染料で耐光堅牢度や溶液安定性が良く、従って、紙用ブルーイング用染料として優れていることが分かった。 As is apparent from the evaluation results regarding the dye of Comparative Example 7, the blue direct dye that does not use dianisidine that is currently used has poor light fastness and solution stability as a dye for bluing in the papermaking field. . On the other hand, from the result of the dye of Example 8, the dye composition containing the two direct dyes of the present invention does not use dianisidine as a raw material, but the reddish blue color as in Comparative Example 6 using a dye using dianisidine as a raw material. It was found that the dye has good light fastness and solution stability, and is therefore excellent as a dye for paper bluing.
本発明によるジスアゾ化合物、その銅錯体である銅化ジスアゾ化合物又はそれらの塩は、水溶性アゾ染料として製紙材料を含むセルロース系繊維材を、高鮮明、高濃度、堅牢で中庸な青色から紫色に染色する染料として有用である。さらに、これらの銅化ジスアゾ化合物又はそれらの塩は、鮮明で染色特性のよい赤みの青色染料組成物が得られるため、ブルーイング用染料として好適に用いられる。 The disazo compound according to the present invention, the copper complexed disazo compound, or a salt thereof, is a water-soluble azo dye that converts a cellulosic fiber material containing a papermaking material from a high-brightness, high-concentration, robust, medium blue to purple. It is useful as a dye for dyeing. Further, these copperated disazo compounds or their salts are suitably used as a dye for bluing because a reddish blue dye composition having clear and good dyeing characteristics can be obtained.
