Linear isotherms have been obtained on. viscose rayon, in the range 20‐90d̀C, with benzidine, o ‐ and m ‐tolidine, and derivatives of aminoazobenzene. o ‐Tolidine has much higher affinity for cellulose than the non‐coplanar m ‐tolidine. Heats of dyeing were found to be constant between 40 and 80d̀C. Non‐ionic dyes do not appear to form aggregates in aqueous solution.
