A reactive dye is disclosed. The reactive dye has the structure of formula (I): wherein X, R, R, R, n, Q, Qand (HOS)are defined in the specification. The reactive dye of the present invention has great build-up property, reproducibility and fastness.

Reactive dye

The present invention relates to a novel reactive dyestuff with a N-alkylamino group, represented by the following formula (I): 

Reactive dyestuff with N-alkylamino group

A dye composition, which comprising: (a) a mono azo dye of the formula (I) wherein R, R, K, Y and m are defined the same as the specification; and (b)at least one azo dye selected from the group consisting of the following formula (II), (III) and (IV), wherein R, R, R, Y, (W), (W'), D, Dand Dare defined the same as the specification. These kinds of dye composition with good stability and build-up. The dye composition are suitable for dyeing and printing of materials containing either cellulose fibers, such as cotton, artificial cotton, linen, and artificial linen, or synthetic polyamide, such as wool, silk, and nylon etc. Dyed materials with excellent properties can be obtained, showing especially outstanding performance in of wash-off, built-up, level-dyeing, photochromism, wet-fastnes, ghosting fastness and light fastness.

Reactive dyestuff composition and their use

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, Dand Dare 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, Dand Dare 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.

Reactive red dye composition and application thereof

The present invention discloses a reactive yellow dye composition comprising component (A) and component (B). The component (A) is a reactive azo dye represented by the following formula (I) or formula (II), The component (B) is a reactive azo dye represented by the following formula (III), wherein the substituents of the formulas (I), (II) and (III) are defined the same as in the specification. Moreover, the reactive yellow dye composition of the present invention has excellent build-up, wash-off and light fastness and can be applied with dyestuffs in other colors.

Reactive yellow dye composition

A dye composition, comprising (A) at least one disazo dye selected from the formula (I) or (II), wherein R, R, R, Dand Dare defined as in the specification; and (B) a diazo dye of the formula (III), wherein (R), (R), Qand Qare defined as in the specification. These dye compositions have high fixation and good build-up. They are distinguished also by high washing off and low nylon staining and they are suitable for dyeing and printing of materials containing either cellulose fibers, such as cotton, artificial cotton, linen, and artificial linen, or polyamide fibers, such as wool, silk, and nylon etc. Dyed materials with excellent properties can be obtained, showing especially outstanding performance in washing off, levelness, build-up, wet fastness and light fastness.

Dye composition and the use thereof

A dye composition, which comprising: a monoazo dye of the formula and a disazo dye of the formula (II) wherein R, R, R, R, R, Y, K, D are defined in this document ; these kinds of dye composition have good stability and build-up. The dye composition are suitable for dyeing and printing of materials containing cellulose fibers, such as cotton, artificial cotton, linen, and artificial linen, or synthetic polyamide, such as wool, silk, and nylon etc.
