A series of temporarily solubilised reactive disperse dyes based on 1‐substituted derivatives of 2‐hydroxypyrid‐6‐one were applied to a 65;35 polyester/cotton blend using a one‐bath dyeing method without dispersing agent. The dyeing behaviour of these dyes on polyester and cotton fabrics, and polyester/cotton blend fabric, were studied. The colour yields of the dyes on the polyester/cotton blend were found to be highly dependent on the initial pH, optimum results being obtained at pH 5. Good levelling and good to excellent fastness properties were obtained on the blend, with the exception of lightfastness, which was moderate.
