Eighteen isomeric dyes, each based on phenylazo‐H‐acid and containing two reactive groups, namely a monochlorotriazine group and a sulphuric acid ester of ß‐hydroxyethylsulphone, were applied to cotton fabric by an exhaustion process at 60d̀C. The following properties were studied: spectra, uptake curves of the dyes before and after adding sodium carbonate, affinity, diffusion rate, and rates of hydrolysis and of reaction with cellulose, as evidenced by fixation and colour yield. Some significant correlations were found, but some missing or poor correlations indicated that there are further parameters or relationships between parameters that remain to be elucidated.
