Abstract

The invention provides a dye composition and a preparation method thereof, a colorant, a photosensitive resin composition and an optical filter. According to the dye composition and the preparation method thereof, the colorant, the photosensitive resin composition and the optical filter, as the dye compound contains an epoxy group, the surface of the optical fiber can be effectively prevented from shrinking while the transmittance is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a dye compound, a preparation method thereof, a colorant, a photosensitive resin composition, and a filter. Background technique [0002] In recent years, there has been an increasing demand for high transmittance, that is, high luminance, and high reliability for color filters used in liquid crystal displays. [0003] As methods for producing color filters, there are pigment dispersion methods using pigments as colorants, printing methods, electrodeposition methods, and inkjet methods, and dyeing methods and dye dispersion methods using dyes and salt-forming dyes as colorants. [0004] Pigments with excellent heat resistance and light resistance are generally used as colorants for optical filters, and the pigment dispersion method is often used in consideration of the accuracy and stability of the forming method. However, because the existing optical filters use pigments as co...
