Patent ID: 7598357

Claim:
A bis-reactive dye with N,N-dialkylamino bridge group of the following formula (I): wherein E 1 , and E 2 each independently are selected from the group consisting of substituted or unsubstituted benzene component, substituted or unsubstituted naphthalene component, and substituted or unsubstituted monoazo component; R is hydrogen, C 1-4 alkyl, C 1-4 alkylcarbonyl, phenyl, nitroso, or C 1-4 alkyl substituted with halogen, hydroxyl, carboxyl or sulfo; (R 1 ) 0-3 , and (R 2 ) 0-3 each independently are 0 to 3 identical or different groups, and each of R 1 , and R 2 is independently selected from the group consisting of hydrogen, halogen, hydroxyl, carboxyl, sulfo, nitro, cyano, C 1-4 alkyl, C 1-4 alkoxy, ureido, and amido; R 3 , and R 4 each independently are hydrogen or C 1-4 alkyl; R 5 , and R 6 each independently are hydrogen, C 1-4 alkyl, or phenyl; G, and G′ each independently are selected from the group consisting of hydrogen, Q, and substituted or unsubstituted C 1-4 alkyl; (R 7 ) 0-3 is 0 to 3 identical or different groups, and each of R 7 is independently selected from the group consisting of hydrogen, halogen, hydroxyl, carboxyl, sulfo, nitro, cyano, C 1-4 alkyl, C 1-4 alkoxy, ureido, and amido; B, and B′ each independently are selected from the group consisting of a direct bond, —SO 2 —, and —CONH—(CH 2 ) k —SO 2 —; k is an integer of 1, 2, 3, 4, 5, or 6; Q is selected from the group consisting of —SO 2 —U, —CONH—(CH 2 ) d —SO 2 —U, —O—(CH 2 ) r —CONH—(CH 2 ) d —SO 2 —U, β-thiosulfatoethylsulfonyl, —R′—SO 2 —U, and —R′—U′; R′ is C 1-4 alkyl or phenyl; d, and r each independently are an integer of 2, 3, or 4; U is —CH 2 CH 2 W, or —CH═CH 2 ; W is —Cl, —OSO 3 H, —OPO 3 H, quaternary ammonium, pyridine, carboxypyridinium, methylpyridinium, carbonamidopyridinium, or R 8 , and R 9 each independently are hydrogen, or C 1-4 alkyl; U′ is α,β-halopropionyl, α-halopropionyl, β-halopropionyl, or α-haloacrylol; X is halogen; m, and n each independently are an integer of 2, 3, or 4; and the ring with the dashed lines represents an optional fused benzene ring.
