Though several authors have previously studied the equilibrium sorption properties of the anilides of 2‐hydroxy‐3‐naphthoic acid, no measurements of the diffusion coefficients of these molecules in cellulose have been made. A suitable apparatus is described for measuring the rapid rates of dyeing which occur, using thick cellulose model filaments. Diffusion coefficients and energies of activation for diffusion of six coupling components have been evaluated.
