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 invention relates to a triarylmethane dye and application thereof, and belongs to the technical field of dye compounds. By designing the structure of the triarylmethane dye, the dye compound with relatively good thermal stability and relatively high transmittance is obtained, and the optical filter prepared from the triarylmethane dye has excellent comprehensive performance.

This invention provides a triarylmethane dye and its applications, specifically a triarylmethane dye, a coloring composition, and a filter. By designing the structure of the triarylmethane dye, this invention yields a triarylmethane dye with excellent performance and high thermal stability.

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.
