Monitoring the hydrolysis of Ostazine Black V‐B reactive dye was found to be possible by matrix‐assisted laser desorption/ionisation time‐of‐flight mass spectrometry (MALDI‐TOFMS). All the desired substances were identified in a mixture of the dye‐bath. The process of the substrate reactive dye hydrolysis was qualified with hydrolysis rate constants k 1 (2.0 ± 0.3 h −1 ) and k 2 (0.6 ± 0.1 h −1 ). The method developed is important for the dyeing industry and for following the colouration process. Copyright © 2000 John Wiley & Sons, Ltd.
