APPLICATION EXAMPLE 1

[0109] 5 parts of the dye obtained in example 1 and 50 parts of sodium chloride were dissolved in 999 parts of water, and 5 parts of sodium carbonate, 0.7 parts of sodium hydroxide (in the form of a 32.5% strength aqueous solution) and, if necessary, 1 part of a wetting agent are added. This dyebath was entered with 100 g of a woven cotton fabric. The temperature of the dyebath was maintained at 25 C. for 10 minutes to start with, then raised over 30 minutes to the final temperature 60 C. and held at that temperature for a further 60 to 90 minutes. Thereafter the dyed goods were rinsed first for 2 minutes with water and subsequently for 5 minutes with water. The dyed goods were neutralized at 40 C. in 1000 parts of an aqueous solution containing 1 part of 50% strength acetic acid for 10 minutes. This was followed by rinsing with deionized water at 70 C. and then by soaping off at the boil for 15 minutes with a laundry detergent, rinsing again, and drying. This gives a strongly colored navy dyeing having very good fastness properties.
