Embodiment Construction

[0007] The preparation of a kind of complex active bright yellow dye B-6GLN of the present invention is: dissolving p-(vinylsulfone-based sulfate) aniline, carrying out diazotization after filtration, then condensation, coupling, salting out, filtration and drying to obtain Monomer B-6GLN reactive bright yellow dye. Mix the monomer B-6GLN active bright yellow dye, dustproof agent and co-solvent in the following ratio: B-6GLN60-94%, butyl oleate 1-10% and co-solvent 5-30%, and grind to the required particle size .

Abstract

A composite reactive bright yellow dye is prepared from the reactive bright yellow dye B-6GLN (60-94 wt.%), dust-proofing agent (1-10) and solubilizer (5-30). Its advantages are gay color, high colorfastness and pollution.

Description

technical field [0001] The invention relates to a composite reactive bright yellow dye with reactive bright yellow dye B-6GLN as the main component. Background technique [0002] At present, the B-6GLN reactive bright yellow dye produced by the dyestuff manufacturer is a monomeric compound. The color fastness of this kind of dye is relatively low, especially the color brightness is poor, the dust is large when used, and it is not easy to wash. Contents of the invention [0003] In order to improve the brilliance, color fastness and performance of the dye, the technical solution of the present invention is: a composite reactive bright yellow dye is mainly composed of B-6GLN reactive bright yellow dye, dustproof agent and cosolvent. [0004] The composite reactive bright yellow dye of the invention mainly consists of 60-94% reactive bright yellow dye B-6GLN, 1-10% dustproof agent and 5-30% cosolvent, and the dustproof agent is oleic acid ester. [0005] The structural form...
