Abstract
새로운 반응성염료 개발의 일환으로 trifluoro-s-triazine을 반응성분으로 이용하여 한 분자에 2개의 서로 다른 chromophore를 가지는 반응성염료를 합성한 다음, 이의 가수분해속도와 면섬유에 대한 염색성을 조사하였다. 이 염료의 유사 일차 가수분해속도상수, kw는 pH=10.0, 온도 60℃에서 kw=2.6×10-2min-1로서 monochlorotriazine 반응성염료보다 높은 값을 보였으며 염착률과 고착율 역시 monochlorotriazine 계 염료보다 우수하였다. 얻어진 반응성 염료는 황색계열로서 수율은 75%였다.

Triazinyl reactive dye containing two different chromophore was synthesized by using trifluoro-s-triazine as reactive component. The yield of this dye was 72% and its colour was yellowish red as a mixed shade. The hydrolysis rate and dyeing properties of this dye were studied and compared with monochlorotriazinyl reactive dye. It was found that monofluorotriazinyl reactive dye showed much higher hydrolysis rate than monochlorotriazinyl reactive dye.
