Previous work has been continued on the transfer of dye, during steaming, between a solid film of thickener substance and a film of regenerated cellulose in contact with it. Films were made from a variety of natural starches and other typical thickening agents. The general characteristics of dye transfer over the steaming period uro similar for most of the thickeners examined, but the proportion of dye transferred at equilibrium may vary considerably between one thickener substance and another. The presence of appreciable numbers of anionic groups in the thickener molecule may lead to the rapid and complete transfer of dye to the cellulose. Possible relations between the chemical constitution of the thickener and the efficiency of dye transfer are discussed.
