The invention relates to coloured and/or fluorescent copolycondensates which are obtained by reaction of colourants substituted by at least two reactive groups which do not interfere with one another, with selected cyclic dicarboxylic acids (especially 1,4-cyclohexanedicarboxylic acid), aliphatic diols (especially ethylene glycol), cyclic diamines (especially isophoronediamine) and/or amino acids in particular amounts.
这项发明涉及通过对至少具有不相互干扰的两个反应基团的
着色剂与选定的环形二
羧酸(尤其是
1,4-环己二羧酸)、脂肪二醇(尤其是
乙二醇)、环状二胺(尤其是异戊二胺)和/或特定量的
氨基酸进行反应而获得的着色和/或荧光共聚酰胺。
