Substantivity of azoic coupling components "azotols"

A correlation between the chemical structure of azoic coupling components (hereafter referred to as azotols) and their affinity for cotton has been attempted. The theoretically computed correlation equations of the practical affinity with the van der Waals surface, the molecular volume and the hydrophobicity are reported. The hypothesis of microcrystalline multilayered micellesʹ implication in the sorption of azotols to a cellulose support is sustained.
