Abstract
Provided is a reactive dye mixture, comprising (i) one or more reactive dyes represented by Formula 1, and (ii) one or more reactive dyes represented by Formula 2: The dye mixture of the present invention can realize a color that is difficult to be achieved by a single dye when dyeing a fiber material containing nitrogen or hydroxyl group, particularly a cellulose fiber material, exhibits a superior absorptivity and fixability, particularly very high light fastness and wet fastness, and thus provides a variety of balanced physical properties which are required in dyeing.
Claims11
A reactive dye mixture, comprising
- (i) one or more reactive dyes represented by Formula 1, and
- (ii) one or more reactive dyes represented by Formula 2:
- wherein:
- R1, R2, R6 and R7 are independently hydrogen or C1-C4 alkyl, 2-hydroxyethyl, 2-chloroethyl, or 2-fluoroethyl group;
- R3, R4 and R5 are independently hydrogen, sulfo, C1-C4 alkyl, C1-C4 alkoxy, hydroxyl, halogen, unsubstituted or C1-C4 alkyl substituted amino, phenylamino, acetylamino, C2-C4 alkanoylamino, benzoylamino, or ureido group;
- A is a substituent group of
- wherein R8 is C1-C4 alkyl, unsubstituted or substituted phenyl, the substituted phenyl including nitro-substituted phenyl and cyano-substituted phenyl, or an amino group;
- X1 and X2 are independently halogen, hydroxyl, unsubstituted or substituted amino, unsubstituted or C1-C4 alkyl substituted phenylamino, unsubstituted or carbamoyl or carboxy substituted pyridinyl, morpholino, or an N-heterocyclic group further containing a hetero atom;
- D1 is a substituent group of
- wherein R9 is hydrogen, sulfo, C1-C4 alkyl, C1-C4 alkoxy, halogen, 2-hydroxyethyl, 2-chloroethyl, or 2-fluoroethyl group;
- and Q1 is a radical of —SO2-Z or —CONH—(CH2)r—SO2-Z, wherein Z is vinyl or a radical of —CH2—CH2—Y, Y being a leaving group, and r is an integer from 1 to 6;
- and
- D2 is a substituent group of
- or
- *—(CH2)1˜4-Q3 wherein R10 is hydrogen, sulfo, C1-C4 alkyl, C1-C4 alkoxy, halogen, 2-hydroxyethyl, 2-chloroethyl or 2-fluoroethyl group;
- and Q2 and Q3 are independently a radical of —SO2-Z or —CONH—(CH2)r—SO2-Z, wherein Z is vinyl or a radical of —CH2—CH2—Y, Y being a leaving group (for example, —Cl, —Br, —F, —OSO3H, —SSO3H, —OCO—CH3, —OPO3H2, —OCO—C6H5, —OSO2—C1-C4 alkyl or —OSO2—N(C1-C4 alkyl)2), and r is an integer from 1 to 6.
