A spectrophotometric method for the simultaneous determination of dyes with spectral interaction in three-colour baths by use of multiple linear regression with indirect calibration has been developed. This method discretely allows the componets of the dyeing bath to be quantified with errors of less than 3% and with 1-2 min of sampling. The method has been applied to monitor the dyeing of chromium-tanned bovine leather splits subjected to various retanning procedures.
