The paper is concerned with recent knowledge of impregnation with Naphtol AS and of coupling conditions. Influence of the type of alkali in the impregnation bath on the dyeings and on the rate‐of‐absorption curves of various coupling components is discussed. The chemistry of the coupling of azoic combinations on vegetable fibres is outlined, and practical aspects of the buffering of the developing baths are considered. The base printing style also is briefly described.
