- the Raney nickel was then separated off, the resulting solution was concentrated and added to 3 g (0.03 mol) of 2-acetaminophenol in 30 ml of ethanol and 50 ml of ethyl acetate. A solution of 4.2 g of sodium carbonate and 50 ml of water was added to the resulting mixture. A solution of 5.7 g (0.025 mol) of ammonium peroxodisulfate in 50 ml of water was then added dropwise. The organic phase was concentrated and the dye thus obtained was purified by column chromatography.
- the mixture was neutralized with 25% by weight ammonia water and the resulting nitroso compound was shaken out with ethyl acetate, which passed into the organic phase.

After the reduction, the catalyst was separated off and the solution was concentrated. A little ethanol was added to the resulting amino compound and a suspension of 4.9 g (0.025 mol) of the compound of the formula
- the resulting printing ink is applied with a 6 ⁇ doctor knife onto a 6 ⁇ m thick polyester film, on the back of which a suitable sliding layer is applied, and blown dry with a hair dryer for 1 minute. Before the ink ribbon can be printed, it must be left to air dry for at least 24 hours, since residual solvents can impair the printing process.
- the ink ribbons are printed on commercially available video printing paper (type VY-S from Hitachi) on a computer-controlled experimental arrangement which is equipped with a commercially available thermal head.
- the energy output of the thermal head is controlled by changing the voltage, the set pulse duration being 7 ms and only one pulse being output at a time.
- the energy delivered is between 0.7 and 2.0 mJ / dot.
- the first value relates to a binder based on polyester, the second to a binder based on polyvinyl butyral.
- dyes 5 and 28 brilliant dyeings in shades of blue and turquoise are obtained on polyester fabric under customary dyeing conditions (HT process). If the tert-butyl group contained in dyes 5 and 28 is replaced by a methyl group, the dye decomposes during the dyeing process. This demonstrates the high stability of the dyes according to the invention.
