With disperse dyes which are insufficiently soluble in cellulose acetate fibre to yield a full shade, the difficulty can be overcome by using a mixture of two or three dyes of similar hue and chemical composition. The components of the mixture must be carefully chosen, as some dyes interact to give a compound which has low solubility in the fibre. There is no evidence that the solubility in cellulose acetate of a mixture of disperse dyes can exceed the sum of the solubilities of the individuaj components. Interaction can also occur when a mixture of disperse dyes is dissolved at 22d̀C in ethanol, hexane, or 0.2% aqueous Ultravon W.
