摘要
合成了系列ＳＮ型活性染料，并研究了其颜色深浅与其结构的关系，结果表明：ＳＮ型活性偶氮染料的颜色深浅受电子效应和空间效应的影响；受电子体的吸电子能力增强，导致吸收光谱产生深色位移，空间障碍使吸收光谱产生浅色位移。
A series of SN type reactive dyes have been synthesised and the relstion ship between the color and dye constitution has been studied inthis Paper.The result showed it depend on the effect of electron and space whether the colour of SN type reactive dyes is darker or Lighter.Darker colour effect will be produced when the ability of attracting electron of acceptor becomes strong and lighter colour effect will be produced when the space harrier exists.
