Acid red dye composition

TL;DR: In this article, an acid red dye composition, mainly comprising a component A made by one or a plurality of structures as (I) and a component B made by a plurality or a single structure as (II), was proposed.

Abstract: The invention provides an acid red dye composition, mainly comprising a component A made by one or a plurality of structures as (I) and a component B made by one or a plurality of structures as (II). The weight percentage of the component A is 1 to 99% while the weight percentage of the component B is 1to 99%. The invention of the acid red dye composition is particularly suitable for printing anddyeing wool, blends, silk, nylon and protein fiber together with polyamide fiber and other blending fabrics. In printing and dyeing the fiber materials, red dyed fabric with stable thermal sensitivity, bright color, high color fastness and other excellent performance can be produced by adjusting the proportion of various components.
