摘要
本文指出了活性染料品种开发中一个值得注意的方向，在桥基上或其邻近结构中引入烷基及其衍生物，增加空间障碍，从而导致反应活性增大和直接性降低，改善染料的染色性能。这一倾向将导致活性染料新品种质量提高和基础研究的深入，应引起国内染料界的注意。
It is an direction for the development of new reactive dyestuffs that introducingalkyl group and its derivative at the bridged group or its neighboring structure to increasingsteric hindrance. This can increase reactivity and decrease affinity. then improvement thedyeing property.
