Patent ID: 7540883

Claim:
A reactive yellow dye composition, comprising: (A) 98% to 50% by weight of at least one reactive azo dye represented by the following formula (I) or formula (II), wherein (R 1 ) 0-3 represents 0, 1, 2, or 3 R 1 substituents, which can be the same or different, selected from the group consisting of: halogen, carboxyl, sulfo, C 1-4 alkyl and C 1-4 alkoxyl; R 2 is H, COCH 3 or CONH 2 ; Q is —NH—CO—CH(Hal)-CH 2 (Hal), —NH—CO—C(Hal)=CH 2 or —SO 2 —Y, wherein Y is —CH 2 CH 2 OSO 3 H, —CH═CH 2 or —CH 2 CH 2 U, U is a leaving group which is eliminable by a base; Hal is halogen; X is H or wherein R 7 and R 8 each independently is selected from the group consisting of: H, methyl, —COOH, —OCH 3 , —OC 2 H 5 , —SO 3 H, —Cl and —SO 2 Y, wherein Y is defined the same as above; wherein R 3 is H, COCH 3 or CONH 2 ; R 9 is H, methyl, —OCH 3 , —OC 2 H 5 , —SO 3 H or —Cl; D is the following (D-a) group, wherein (R 1 ) 0-3 are defined the same as the (R 1 ) 0-3 of the reactive azo dye represented by formula (I); W is wherein R 10 is H, methyl or ethyl; D 1 is the following (D-b) group, wherein (R 1 ) 0-3 and Q are defined the same as that of the reactive azo dye represented by formula (I); and (B) 2% to 50% by weight of at least one reactive azo dye represented by the following formula (III), wherein R is H or carboxyl; X is defined the same as the X of the reactive azo dye represented by formula (I); Z is H, —CH 2 SO 3 H, —CH 2 CH 2 SO 3 H, —CH 2 COOH or —CH 2 CH 2 COOH; D 2 and D 3 each independently is selected from the group consisting of the following (D-a) and (D-b) groups, wherein (R 1 ) 0-3 and Q are defined the same as that of the reactive azo dye represented by formula (I).
