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.

Description

(1) Technical field [0001] The invention relates to an acid red dye composition, especially a bright red acid red dye composition. (2) Background technology [0002] So far, people have found many kinds of single red acid dyes. The dye industry generally uses a single red dye monomer as the basic tone of the three primary colors; patent CN424360A introduces a red improved weak acid dye single body, it is suitable for staining in a neutral bath. US Patent No. 4,618,674A1 introduces a red dye monomer, which is mainly used with two other blue and yellow-orange dyes to form three primary colors. As we all know, when a single dye is formulated into a composite dye with excellent performance, it can not only improve its coloring performance, but also not be limited by a single color. There are few reports on acid composite red dyes at home and abroad. (3) Contents of the invention [0003] The purpose of the present invention is to provide an acid red dye composition with goo...
