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.
