Patent ID: 7641724

Claim:
A dye mixture comprising at least one dye of formula together with at least one dye of formula wherein R 1 and R 2 are each independently of the other hydrogen or unsubstituted or substituted C 1 -C 4 alkyl, (R 3 ) 0-3 denotes from 0 to 3 identical or differing substituents from the group halogen, C 1 -C 4 alkyl, C 1 -C 4 alkoxy, carboxy and sulfo, A is unsubstituted or substituted phenylene, naphthylene, or C 2 -C 8 alkylene which may be interrupted by oxygen, X 1 is halogen or a non-fibre-reactive substituent, q is the number 0 or 1, Y 1 , Y 2 , Y 3 and Y 4 are each independently of the others a fibre-reactive radical of formula —SO 2 -Z (3a), —NH—CO—(CH 2 ) m —SO 2 -Z (3b), —CONH—(CH 2 ) n —SO 2 -Z (3c), —NH—CO—CH(Hal)—CH 2 -Hal (3d), —NH—CO—C(Hal)═CH 2 (3e) or wherein X 2 is halogen, T independently has the definition of X 2 , is a non-fibre-reactive substituent or is a fibre-reactive radical of formula (R 6 ) 0-2 denotes from 0 to 2 identical or differing substituents from the group halogen, C 1 -C 4 alkyl, C 1 -C 4 alkoxy and sulfo, Z is vinyl or a radical —CH 2 —CH 2 —U and U is a group removable under alkaline conditions, Q is a group —CH(Hal)—CH 2 -Hal or —C(Hal)═CH 2 , m and n are each independently of the other the number 2, 3 or 4, and Hal is halogen, and (R 4 ) 0-2 and (R 5 ) 0-2 denote, each independently of the other, from 0 to 2 identical or differing substituents selected from the group C 1 -C 4 alkyl, C 1 -C 4 alkoxy and sulfo, and one of the fibre-reactive radicals Y 3 and Y 4 is a radical of formula (3a), (3b), (3e), (3d) or (3e) and the other of the fibre-reactive radicals Y 3 and Y 4 is a radical of formula (3b) or (3f).
