Abstract

The invention discloses an active red dye composition and a dye product. The active red dye composition mainly comprises 40-90 parts by mass of a composition A, 5-40 parts by mass of a composition B, 0-20 parts by mass of a composition C, and 0-20 parts by mass of a composition D; the composition A is selected from at least one of dye monomer compounds with the structure shown as a formula (I) in the specification; the composition B is selected from at least one of dye monomer compounds with the structure shown as a formula (II) in the specification; the composition C is selected from at least one of dye monomer compounds with the structure shown as a formula (III) in the specification; the composition D is selected from at least one of dye monomer compounds with the structure shown as a formula (IV) in the specification. The active red dye product comprises the active red dye composition. The dye product is good in level-dyeing property, high in build up index, excellent in various color fastness and protrude especially in color fastness to washing and color fastness to friction when being applied to printing and dyeing of cellulose-containing fiber materials.

Description

(1) Technical field [0001] The invention relates to a reactive red dye composition and a reactive red dye product prepared therefrom. (2) Background technology [0002] With the improvement of people's living conditions, the requirements for dyes are getting higher and higher. As a color species with a large amount of consumption, red reactive dyes not only require good level dyeing and lifting power, but also have good color fastness. Many red reactive dye varieties commonly used at present are difficult to possess the above-mentioned comprehensive performances, such as published patents CN1112947A, CN1807518A and CN101633795A, etc., which are still unsatisfactory in terms of washing fastness and color fastness to rubbing. (3) Contents of the invention [0003] The purpose of the present invention is to provide a reactive red dye composition and the reactive red dye product made from the composition. When the dye product is applied to printing and dyeing of cellulose fib...
