Description

Reactive dye composition and its use

This disclosure relates to a reactive dye composition and its use, which is suitable for various colors and concentrations, and is more suitable for light color dyeing and its use.

Prints with high daylight properties mostly use dark products with high concentrations of dyes, so products that are used in light-colored prints with high daylight properties have always been eagerly awaited by the market. However, when dyes currently available on the market are used to dye light color concentrations, the daylight fastness is only about level 2, or even only level 1, which does not meet market demand. In addition, in order to improve the daylight fastness of light-colored dyes, most of the dyes currently available on the market contain metals such as cobalt, chromium or copper, such as reactive dye BK8.

In view of this, there is a great need for a dye that is suitable for dyeing light colors and has high light fastness, and eliminates the use of metal dyes to achieve the purpose of green chemistry.

The present disclosure provides a reactive dye composition, including: a red reactive dye, and at least one reactive dye selected from a group consisting of a blue reactive dye and an orange reactive dye; and an organic buffer, wherein the red reactive dye is shown in the following formula (I), the blue reactive dye is shown in the following formula (II), and the orange reactive dye is shown in the following formula (III):

In the present disclosure, a red reactive dye of formula (I) is mixed with a blue reactive dye of formula (II) and/or an orange reactive dye of formula (III) to form a reactive dye composition.
