The work reported by Daruwalla and Turner1 has been extended to include a study of the transfer of selected aminoanthraquinone and aminoazo disperse dyes to secondary cellulose acetate. The effects of particle size and chemical structure of dye, presence of dispersing agents, and different thickener compositions have been examined for appropriate conditions of application. With the majority of the dyes studied a constant partition of dye between cellulose acetate phase and thickener phase at equilibrium is maintained with increasing proportions of dye in the system until saturation of the cellulose acetate with the dye is reached. Study of binary mixtures of selected dyes indicates that the transfer characteristics of one component are unaffected by the presence of the other. The results are discussed with special reference to quantitative studies by other workers on the behaviour of these dyes during dyeing.
