Abstract
Reactive dyestuffs of the formula ##STR1## in which D is the residue of an organic dyestuff, R is hydrogen or a lower alkyl, R.sub.1 is hydrogen or a substituent, R.sub.2 is hydrogen, halogen, substituted or unsubstituted alkyl, alkenyl, aralkyl or aryl radical, carboxylic acid ester radical, carboxylic acid amide radical, alkylsulphone, or arylsulphone; and F is fluoro; and process for the preparation of such dyestuffs. These dyestuffs are particularly useful in dyeing materials containing hydroxyl groups and nitrogen, e.g. regenerated cellulose, wool, silk, synthetic polyamide, and polyurethane which dyeings possess excellent fastness to wet processing and good fastness to washing, milling and potting on wool.
Claims5
A reactive dyestuff having the formula ##STR89## wherein D' stands for a sulphonic acid group containing phthalocyanine dyestuff, q stands for the number 0 or 1, R' stands for hydrogen, --CH.sub.3 or --C.sub.2 H.sub.5, R".sub.1 stands for Cl or F, R".sub.2 stands for Cl, F or CH.sub.3, and F stands for fluoro, the group ##STR90## being bound to an aromatic carbocyclic carbon atom of D'.
A reactive dyestuff of the formula ##STR94## wherein L and L' independently stand for sulphonic acid or chloro;
- r stands for an integer from 0 to 2;
- q stands for the number 0 or 1;
- R' stands for hydrogen or methyl;
- R'.sub.1 and R'.sub.2 independently stand for hydrogen, chloro, bromo, or fluoro;
- F stands for fluoro;
- and
- Pc stands for nickel-phthalocyanine, copper-phthalocyanine, or either of said phthalocyanines substituted by 1-4 substituents selected from the group consisting of sulphonic acid, sulphonic acid amide, sulphonic acid alkylamide of 1-3 carbon atoms, and sulphonic acid dialkyl amide of 1-3 carbon atoms in each alkyl group, provided that the maximum number of said 1-4 substituents that may be represented by any one acid or amide is 2.
