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.

Embodiment 1

[0079] Put 30g of acid chloride (0.0144mol) into a 250ml four-necked flask containing 100g of dichlorobenzene, heat the oil bath to 130°C, add dropwise 0.84g (0.00288mol) of rosinamine, and 3.67g (0.02592mol) of 3-chloro- The dichlorobenzene solution of 2-methylaniline was added dropwise for 30 minutes, and after the dropwise addition was completed, the temperature was raised to 150° C. for 3 hours. Filtering at lower temperature, washing with methanol and then water, recovering the solvent, and drying the filter cake to obtain the bis-azo condensation compound.

[0080] The electron microscope observation results of the figure 2 shown.

[0081] Its X-ray diffraction results are as follows Figure 4 shown.

[0082] Using infrared spectrometer to carry out infrared spectrum test, the results are as follows Image 6 shown. Depend on Image 6 It can be seen that due to the introduction of rosinamine, there are multiple methylene groups in the product, and its infrared spec...

Embodiment 2

[0085] Put 30g of acid chloride (0.0144mol) into a 250ml four-necked flask containing 100g of dichlorobenzene, heat the oil bath to 130°C, add dropwise 1.25g (0.00432mol) of rosinamine, and 3.46g (0.02448mol) of 3-chloro- The dichlorobenzene solution of 2-methylaniline was added dropwise for 30 minutes, and after the dropwise addition was completed, the temperature was raised to 150° C. for 3 hours. Filtering at lower temperature, washing with methanol and then water, recovering the solvent, and drying the filter cake to obtain the bis-azo condensation compound.

[0086] Its electron microscope observation result, X-ray diffraction pattern and infrared spectrogram are similar to the product obtained in Example 1;

[0087] The elemental analysis results are: C, 44.85; H, 38.56; Cl, ​​4.79; N, 8.21; The molecular formula thus determined is C 44.95 h 38.45 N 8.15 o 6 Cl 4.85 . According to calculation, the content of C and H elements in the product prepared in Example 2 in...

Abstract

The invention discloses a pigment composition containing a bisazo condensation compound and a preparation method of the pigment composition.The structure of the bisazo condensation compound is shown in the description, wherein X and Y indicate fatty amino or arylamino.The bisazo condensation compound with the specific structure is mixed into pigment yellow 93, and the yellow pigment composition is obtained; the intensity of green light of the yellow pigment composition is higher, the transparency is significantly increased, the heat resistance, solvent resistance, dispersity and rheological property on ink are comparable to those of existing pigment yellow 93, and the yellow pigment composition is suitable for high-transparency ink.

Description

technical field [0001] The invention belongs to the field of chemical dyes, in particular to a pigment composition containing a rosin amino 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...
