Abstract

The invention discloses a colorant composition for a color filter, and a photosensitive resin composite as well as application of the colorant composition and the photosensitive resin composite. The photosensitive resin composite comprises the colorant, an alkali-soluble resin, a polymeric monomer and a photopolymerization initiator, wherein the colorant comprises a polymer dye compound containing double bonds and a pigment. The polymer dye compound containing the double is obtained from the following copolymerizable monomers by virtue of a copolymerization reaction: 1) an amino-containing allyl monomer obtained by reacting an amino-containing basic dye with an acyl chloride-containing allyl monomer; 2) an allyl monomer containing one or more than two carboxyl groups or carboxylic acid anhydrides; 3) a hydroxyl-containing allyl monomer. The polymer dye compound contains the double bonds, and the photosensitive resin composite prepared from the polymer dye compound is provided with a coat of color excellent in heat resistance, light resistance and transmittance, and no residue is left during development; besides, even under low exposure, the edge defect and the sidewall erosion of patterns can be avoided.

Description

technical field [0001] The present invention relates to an application of a dye compound containing a polymerizable double bond, a colorant composition, and a photosensitive resin composition; in particular, to an application of a dye compound containing a polymerizable double bond, a colorant composition, and a photosensitive resin Composition, and application of colorant composition and photosensitive resin composition in preparing color filter in color liquid crystal display device. Background technique [0002] In recent years, there has been an increased demand for high transmittance, that is, high brightness and high reliability, for color filters used in liquid crystal displays. [0003] As a method for producing a color filter, there are pigment dispersion method, printing method, electrodeposition method, inkjet method, etc. using pigments as colorants, and dyeing methods and dye dispersion methods using dyes and salt-forming dyes as colorants. Among them, since th...
