The transfer during steaming of a selected range of the sodium sulphuric esters of leuco vat dyes from a film of starch to an attached film of regenerated cellulose has been studied. Curves relating time of steaming with dye transferred suggest that this transfer is a complicated process. Additions of assistants, such as alkali‐metal carbonates or sodium N ‐benzylsulphanilate, may cause marked changes in the course of the dye transfer. An explanation is put forward which relates the behaviour of the Indigosols in part with the behaviour of some acid dyes which are suitable for printing on regenerated cellulose and in part with the decomposition of the Indigosol as steaming proceeds.
