Description

technical field

[0001] The invention belongs to the field of organic colorants, and in particular relates to a red organic colorant with high temperature resistance, migration resistance and easy dispersion, which is applied to resin coloring and a preparation method thereof. Background technique

[0002] The development of material science has higher and higher requirements for the performance of colorants. In addition to excellent weather resistance, light resistance and various chemical resistance, it also has an impact on the temperature resistance of colorants, migration resistance in resins and dispersibility. higher requirement. Part of the organic colorant is various dyes and solvent dyes with certain water solubility or solvent solubility, and the other part is pigments that are insoluble in water and various application media. Resin coloring can only be solvent dyes and pigments, and water-soluble dyes cannot be used. Although there are many commercial products o...
