Problems solved by technology

[0005] According to market research, although Yellow 93 has high heat resistance and good migration resistance, the transparency of Pigment Yellow 93 needs to be improved. The current Yellow 93 adopts the preparation method and pigmentation method disclosed in the above invention, and the obtained product has transparency. It is still unsatisfactory. For disazo condensation pigments, it is difficult to make a breakthrough in transparency through its own particle adjustment.

Abstract

The invention discloses an octadecylamino bisdiazo condensation compound and a preparing method thereof.(See the formula in the description), wherein X and Y represent an aliphatic amine or arylamine; special aliphatic amine is added in the condensation and amidation process of pigment yellow 93, the bisdiazo condensation compound is formed through mixed crystal synthesis and emits stronger green light, transparency is remarkably improved, heat resistance, solvent resistance, dispersity and rheological property on printing ink of the bisdiazo condensation compound are equivalent to those of existing pigment yellow 93, and the octadecylamino bisdiazo condensation compound is suitable for high-transparency printing ink.

Description

technical field [0001] The invention belongs to the field of chemical dyes, and in particular relates to a disazo condensation compound and a preparation method thereof. Background technique [0002] Bisacetoacetanilide azo condensation pigments are based on the molecular basis of bisacetoacetanilide pigments, and a substituted aromatic ring is connected at both ends of the molecule through an amide bond. This kind of pigment has large molecular weight, strong tinting strength and fastness performance, especially the introduction of more amide groups, which makes it easier for the compound to form intramolecular and intermolecular hydrogen bonds. Such a molecular structure greatly improves the fastness of the pigment. High performance, especially heat resistance and solvent resistance. In plastic coloring, migration resistance is greatly improved. However, due to the high production cost, the price is high, and it is mainly used in high-end occasions. Among them, Pigment ...
