Embodiment 1~4

[0027] A compound cationic dye composition with high light fastness, comprising cationic golden yellow shown in formula (1), cationic brilliant red shown in formula (2), basic magenta green shown in formula (3) and formula ( 4) The cationic blue X-GRRL shown is composed by weight percentage, and the balance is additives. The weight percentage of each component is shown in Table 1;

[0028] Mix the components according to the ratio shown in Table 1, then add additives and water, pulverize the spheroidal ink in the presence of surfactants, and then spray dry to obtain the composite cationic dye composition with high light fastness of the present invention.

[0029] Among them: the cationic golden yellow shown in the formula (1) is selected from the cationic golden yellow X-GL Y28 produced by Hangzhou Jingjiang Ruihua Technology Co., Ltd.; the cationic red shown in the formula (2) is selected from the cationic brilliant red 5GN R14 produced by Hangzhou Jingjiang Ruihua Technology ...

Abstract

The present invention relates to a composite cationic dye composition, and particularly relates to a composite cationic dye composition with high light fastness. The composite cationic dye composition includes the following components by weight: 10-40% of cationic golden yellow shown as a formula (1), 10-30% of cationic bright red shown as formula (3), 1-10% of cationic blue X-GRRL shown as formula (4), and the balance of additives. The dye composition of the present invention can not only improve levelness and dyeing-uptake rate, but also enhance light fastness because of synergistic actions.

Description

technical field [0001] The invention relates to a composite cationic dye composition, in particular to a composite cationic dye composition with high light fastness. Background technique [0002] Cationic dyes are a kind of textile dyes, also known as basic dyes and salt-based dyes, which are in a cationic state when dissolved in water. They are mainly used for dyeing acrylic fibers, and can also be combined with protein molecules with salt and alkali. Cationic dyes It is soluble in water and ionized in aqueous solution to generate positively charged colored ions. The cation of the dye can combine with the acidic group of the third monomer in the fabric to dye the fiber. It is a special dye for acrylic fiber dyeing. [0003] The chemical structure of cationic dyes can be divided into two categories: isolated type and conjugated type. Conjugated cationic dye precursors form conjugated double bonds with dye molecular chromophores, so the hair color is rich and bright, and the...
