Abstract

The invention relates to a photosensitive composite which contains a specific ketoxime ester compound used as a polymerization initiator, an alkali-soluble resin, DPHA (Dipentaerythritol Hexaacrylate) and a colorant. The composite has good storage stability and also has high exposure sensitivity, good developing performance, no wrinkle on formed pattern surfaces and excellent solidifying effect when used for making black matrixes (BM) and RGB (Red Green Blue) of a color filter. The invention also relates to the application of the photosensitive composite in the production of the color filter,and the filter made from the photosensitive composite has high optical transparency and no light leakage.

Description

technical field [0001] The present invention relates to a photosensitive composition, which contains a diphenyl sulfide ketoxime ester compound as a photopolymerization initiator, and also relates to the application of the photosensitive composition in the manufacture of color filters. Background technique [0002] Photocuring refers to the curing process of monomer, oligomer or polymer matrix under light induction, which is widely used in modern microelectronics technology. For example, a color filter as one of the core components of a liquid crystal display includes red (R), green (G), blue (B) polymer materials and a black matrix (BM), of which red, green, and blue are three parts Abbreviated as RGB, both RGB and BM are prepared by light curing technology in the prior art. [0003] The core of photocuring technology lies in the composition of the photosensitive composition. Under the irradiation of ultraviolet / visible light, X-ray or laser at a certain wavelength, the p...
