る)で表わされるモノアゾ化合物及びそれを用いる疎水
性繊維の染色法に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a monoazo compound represented by the formula ({1} in which R means an alkyl group having 1 to 4 carbon atoms) and a method for dyeing hydrophobic fibers using the monoazo compound.
近年疎水性繊維とりわけポリエステル繊維は、その染色
物の付加価値をたかめるべく、従来の無地染色だけでな
く、複雑又は縞簾細な模様柄のえられる捺染又は防抜染
による染色方式が多くなってきた。In recent years, in order to increase the added value of hydrophobic fibers, especially polyester fibers, in addition to the conventional plain dyeing, there has been an increase in the number of dyeing methods using printing or resist discharge printing, which can produce complex or striped patterns. .

良好な抜染性をもち、かつ種々の堅牢度が良好な染料を
作り出す事は非常に困難であった。例えば特公昭43一
鼠56号に記載の染料は抜染性はすぐれているが昇華堅
牢度及び染色物の湿潤堅牢度が十分でない。Among these methods, in the printing method, a sufficiently satisfactory result can be obtained even if the dye used for conventional plain beams is used, but in the method of resist discharge printing, a part or skeleton of the dye matrix is decomposed by the discharge agent. It is required that the structure is such that the polyester fibers do not show dyeing. Furthermore, in order for the obtained discharge prints to have satisfactory practicality, it is necessary that they exhibit sufficient fastness properties. There is a conflict between ease of discharge printing, discharge printing performance, and fastness.
It has been extremely difficult to create dyes that have good discharge properties and various fastnesses. For example, the dye described in Japanese Patent Publication No. 1973-1-56 has excellent discharge printing properties, but the sublimation fastness and the wet fastness of dyed products are insufficient.

ていることは明白である。Furthermore, although the dye disclosed in JP-A-57-49661 has excellent discharge printability and sublimation fastness, the wet fastness of the dyed product is not sufficient. In addition, both dyes have poor thermal decomposition properties. Therefore, the inventors of the present invention should develop a dye that has both good dischargeability and sufficient various fastnesses.As a result of intensive research, the monoazo compound (dye) represented by formula '11 has been found to have extremely good dischargeability and various fastnesses. They discovered that it is a dye with unique properties, and completed the present invention. As shown in Table m, it is clear that the dyes of the present invention are far superior in water fastness and thermal decomposition properties, especially compared to known dyes.
