Claims (6)

  1. 디아조 성분의 수성/산성-용액을 65℃미만의 온도에서, 1분 미만의 기간에 걸쳐 커플링 성분의 수성/알칼리성 용액과 연속적으로 혼합한 다음, 디아조 성분과 커플링 성분의 매스 스트림의 유동을 조정하여 2내지 9사이의 예정된 pH를 고정시키고, 이렇게 하여 커플링 성분의 일부분은 직접 반응하여 제조하고자 하는 아조안료를 생성시키도록 하며 동시에 커플링 성분의 나머지 부분은 미세한 결정성의 반응성 물질로서 침전되도록 개시시켜, 생성된 결정성의 반응성 물질을 후-반응 상에서 비반응 디아조 성분과 반응시켜 제조하고자 하는 아조안료를 생성시킴을 특징으로 하여, 디아조 성분을 65℃미만에서 수성/산성 및 수성/중성 pH-범위에서 난용성인 등량의 커플링 성분과 아조 커플링 반응시켜 아조안료를 제조하는 방법.
  2. 제1항에 있어서, 연속 혼합을 6초 미만의 기간에 걸쳐 수행하는 방법.
  3. 제1항에 있어서, 예정된 pH를 완충물질을 가하여 고정시키는 방법.
  4. 제1항에 있어서, 커플링 성분의 60내지 98%가 직접 반응을 행하여 제조하고자 하는 아조안료를 생성시키는 방법.
  5. 제1항에 있어서, 후-반응상을 포함한 아조커플링 반응중의 온도가 10내지 55℃인 방법.
  6. 제1항에 있어서, 침전된 반응성 커플링 성분이 그들의 화학적 조성에 따라, 그들의 입자 표면에 고착된 에놀레이트, 페놀레이트 또는 나프톨레이트 그룹을 함유하는 방법.
    ※참고사항 : 최초출원 내용에 의하여 공개하는 것임.
