Abstract

본 발명은 하기 일반식(Ⅰ)의 반응성 흑색염료 조성물로 용해성이 우수한 고농도 액체염료의 제조방법에 관한 것이다.The present invention relates to a method for producing a high concentration liquid dye excellent in solubility with the reactive black dye composition of the following general formula (I).

본 발명의 방법에 의해 제조된 반응성 흑색염료 조성물은 수세 및 세탁 견뢰도가 우수하고 액체상태에서 조온으로 장기간 보관하여도, 침전물이 발생하지 않고 염료용액이 안정성이 있어서 자동염색장치에 사용하기에 편리할 뿐만 아니라 경제적인 면에서도 기존 염료에 비해 저렴하게 만들 수 있으며, 건조시켜 고농도의 분말염료를 얻을수 있다.The reactive black dye composition prepared by the method of the present invention has excellent washing and washing fastness, and even when stored in liquid state for a long time at room temperature, there is no sediment and the dye solution is stable, which is convenient for use in an automatic dyeing apparatus. In addition, it can be made economically cheaper than conventional dyes, and can be dried to obtain a high concentration of powder dyes.
