    摘要： New, highly multifunctional reactive dye compounds are provided. The number of leaving groups in the non-chromophoric part of the molecule added to the number of chromophore moieties is at least equal to 5, preferably in the range of from 5 to 12, more preferably from 5 to 6. The new reactive dye compounds preferably have at least two asymmetric bridges.
