Reactive red dye composition and application thereof

The present invention provides a reactive red dye composition comprising (A) 3% to 97% by weight of a reactive azo dye of the following formula (I), wherein W, D1 and D2 are defined the same as the specification; and (B) 97% to 3% by weight of a reactive azo dye of the following formula (II), wherein R, X, Z, D3 and D4 are defined the same as the specification. The reactive red dye composition of the present invention can be utilized to dye cellulose fibers. The cellulose fibers dyed by the reactive red dye composition obtain not only good build-up and level dyeing properties but also an excellent property of white discharging.
