Abstract: A heat-sensitive sublimation transfer cyan dye is of formula (I). In (I), R1 = H, alkyl, alkoxy, alkylcarbonylamino, formylamino or halogen; R2, R3 = alkyl, alkenyl, alkoxyalkyl, aralkyl, aryl, halogenoalkyl, cyanoalkyl; provided that they may be combine to each other to form a ring; and X = a gp. of formula (i) (ii) or (iii). Also claimed is a heat-sensitive sublimation heat-transfer sheet comprising dye(s) of formula (I).

Abstract: A process for rope dyeing cotton yarns a fashionable denim blue color comprises the steps of forming the yarns into a rope; repeatedly immersing the rope in a bath containing a reduced water soluble form of an air oxidizable halogenated indigo derivative; squeezing the rope to remove excess liquid and exposing the damp rope to air oxidation of the reduced indigo derivative; and then further oxidizing the incompletely oxidized reduced indigo derivative in an oxidizing bath containing a chemical oxidant, for example sodium perborate.
