6 results about "Triarylmethane dye" patented technology

The invention provides a triarylmethane dye and application thereof, and particularly provides a triarylmethane dye, a coloring composition and an optical filter. By designing the structure of the triarylmethane dye, the triarylmethane dye with excellent performance is obtained, and the triarylmethane dye has high thermal stability.

The present application relates to the field of printing dye technology, and more particularly to a photochromic printing dye, its preparation method, and its application. The photochromic printing dye provided herein is obtained by dispersing a disperse dye and microcapsules in an organic continuous phase. The disperse dye is selected from indigo dye, anthraquinone dye, or triarylmethane dye. The core material of the microcapsules is an oxidant, and the shell material of the microcapsules is a SiO2 complex. The printing dye provided herein contains microcapsules with an oxidant as the core material. During the washing process, the oxidant is slowly released from the shell material and has strong oxidizing properties. On the one hand, it can have a bactericidal effect. On the other hand, during the drying process, it can react with the disperse dye that is prone to photooxidation, causing the disperse dye to slowly decompose and fade.

The invention discloses a novel triarylmethane dye for blue photoresist color paste and a synthesis method of the novel triarylmethane dye. The dye is a novel triarylmethane dye which is a compound represented by a general formula (I). X in the general formula (I) is a linking group, such as an alkyl substituent and an aryl substituent. At least one of R1-R3 represents a cycloalkyl group which may have a substituent, or an aryl group which may have a substituent. The novel triarylmethane dye has excellent colored light performance, and solubility, thermal stability, light stability, color value and contrast ratio are further improved. The novel triarylmethane dye is suitable for mixed or dye blue photoresist color paste, and the brightness, transparency, weather resistance and dispersity of the color paste can be remarkably improved.

The application discloses a triarylmethane dye for blue photoresist color paste and a synthesis method thereof. The dye is a triarylmethane dye P, which is prepared through the following steps: (1) dissolving an alkyl or aryl triamine MA in a solvent, adding a palladium catalyst, a ligand and an alkali, and reacting with an aryl halide under an inert atmosphere to obtain an intermediate IA; (2) dissolving a dihalogenated diaryl ketone MB in a solvent, adding a palladium catalyst, a ligand and an alkali, and reacting with a disubstituted amine under an inert atmosphere to obtain a target intermediate IB; and (3) condensing the intermediate IA and the intermediate IB to obtain a novel blue triarylmethane dye P. The triarylmethane dye has excellent color performance, is suitable for mixed or dye-based blue photoresist color paste, and can significantly improve the brightness, transparency, contrast and dispersibility of the color paste, and meanwhile, has high hiding power, strong coloring power, and good thermal stability and light stability. In addition, the synthesis method is simple in process and suitable for industrial production.
