A group of medium temperature three primary color disperse dyes

Abstract

The invention discloses a group of medium temperature type three-primary-color disperse dyes. A yellow disperse dye is a mixture formed by 5-20 % of compound shown by a chemical formula (1), 5-40 % of compound shown by a chemical formula (2) and 5-40 % of compound shown by a chemical general formula (3) in percentage by weight; a red disperse dye comprises one or more monomers in a compound shown by a chemical general formula (4); and a blue disperse dye comprises one or more monomers in a compound shown by a chemical general formula (5). The medium temperature type three-primary-color disperse dyes disclosed by the invention have the advantages as follows: medium temperature type three primary colors beautiful in colored lights and high in intensities; the colored lights of the medium temperature type three primary colors are similar to the original three primary colors; the medium temperature type three-primary-color disperse dyes have the advantages of perfect compatibility, high lifting force, distillation, excellent fastness and the like during dyeing and are a group of medium temperature type three-primary-color disperse dyes with excellent comprehensive performances.

Description

technical field [0001] The invention relates to a group of medium-temperature three-primary-color disperse dyes, which are especially suitable for dyeing and printing polyester fibers. Background technique [0002] In recent years, with the improvement of living standards, people's awareness of environmental protection has gradually increased. Therefore, in the printing and dyeing industry, higher requirements have been put forward for the fastness and environmental protection requirements of dyes. The three primary colors of low-temperature disperse dyes refer to yellow RGFL, red 3B, and blue 2BLN, commonly known as "the old three", which are one of the indispensable basic colors for polyester fiber coloring. The compatibility of the three is excellent, and the dyeing rate is exactly the same, but the sublimation fastness of the three is poor. Among them, the yellow RGFL has an azo structure, which is cheap, bright in color, and has good interdependencies. However, recent ...

AI Technical Summary

Problems solved by technology

At present, there is no group of medium-temperature three-primary-color disperse dyes with good sublimation fastness, good compatibility, environmental protection, economy, and shade similar to the "old three".
