Procedure

A similar tinctorial result is obtained if dyeing is carried out with 0.162% of the dye Vat Orange 3 of C.I. No. 59,300 by the IK process at 40° C. and a falling temperature, instead of the dye mentioned above, and if, instead of sodium carbonate and sodium nitrite, the following chemicals are employed: 9 cm3 /l of 32.5% strength sodium hydroxide solution, 4 g/l of hydrosulfite, concentrated powder (sodium dithionite), and 15 g/l of calcined sodium sulfate, as well as 2 g/l of a 50 percent strength by weight formulation of the condensation product formed from stearic acid and ammonia which has been oxethylated with 5 moles of ethylene oxide.
