Description

EXAMPLES

Example 1

[0092] 53 parts of an electrolyte-containing dye powder containing the blue azo dye of the formula (I-3) [component (I)], and 47 parts of an electrolyte-containing dye powder containing the blue formazan dye of the formula (II-6) [component (II)], were mixed mechanically with one another.

[0093] The resultant dye mixture of the invention provides blue dyeings and prints, on cotton for example, under the dyeing conditions customary for reactive dyes.

Example 2

[0094] 45 parts of an electrolyte-containing dye powder containing the blue azo dye of the formula (I-1) [component (I)], 35 parts of an electrolyte-containing dye powder containing the blue formazan dye of the formula (II-1) [component (II)], and 20 parts of an electrolyte-containing dye powder containing the blue formazan dye of the formula (II-2) [component (II)] were mixed mechanically with one another.

[0095] The resultant dye mixture of the invention provides blue dyeings and prints, on cotton for example, under the dyeing conditions customary for reactive dyes.

Example 3

[0096] 20 parts of an electrolyte-containing dye powder containing the blue azo dye of the formula (I-4) [component (I)], 24 parts of an electrolyte-containing dye powder containing the blue azo dye of the formula (I-3) [component (I)'], 30 parts of an electrolyte-containing dye powder containing the blue formazan dye of the formula (II-1) [component (II)] and 26 parts of an electrolyte-containing dye powder containing the blue formazan dye of the formula (II-5) [component (II)] were mixed mechanically with one another.
