摘要:
Phthalocyanine reactive dyestuffs of the formula ##SPC1##Wherein Pc, R.sub.1, R.sub.2, R.sub.3 -R.sub.5, a, b and c and Z have the meaning given in the description. They are outstandingly suitable for dyeing and printing materials containing cellulose, such as natural and regenerated cellulose, in accordance with the techniques known for the purpose. The new dyestuffs are also suitable for dyeing materials containing amide groups, such as wool, silk and synthetic polyamides. Dyeings obtained on textile cellulose, in particular, distinguish themselves by very good fastness properties, especially fastness to light and to wet processing.
