Problems solved by technology

In actual use, the pixels with high optical density and the resin base layer system often have high content of pigments, carbon black and other coloring materials, and the increase in the concentration of coloring materials will have adverse effects on resolution, substrate adhesion, and development residues, not only It is necessary to increase the exposure amount or extend the exposure time in the exposure process, and also reduce the accuracy of the color filter

specific Embodiment approach

[0073] The present invention will be further described by the following examples, but it should not be interpreted as limiting the protection scope of the present invention.

[0074] Preparation Example

[0075] According to the formula listed in table 1, the photosensitive resin composition of preparation embodiment 1-8 and comparative example 1-4, wherein the structure of photoinitiator A1-A4 in comparative example 1-4 is as follows:

[0076]

[0077] Table 1

[0078]

[0079] The prepared photosensitive resin composition is dissolved in 100 parts by mass of solvent propylene glycol monomethyl ether acetate (PGMEA), and mixed uniformly to form a liquid composition;

[0080] Use a spin coater to coat the liquid composition on a glass substrate, then dry at 100°C for 5 minutes to remove the solvent to form a coating film with a film thickness of 8 μm; in order to obtain a coating film with the above thickness, the coating process can be completed once It can also be d...

Abstract

The invention discloses a photosensitive resin composition. The photosensitive resin composition comprises ultraviolet photosensitive prepolymer resin, an active diluent monomer, an oxime ether photoinitiator represented by the formula (I), and a colouring agent. The photosensitive resin composition has the good exposure sensibility and developing property; on the premise of low amount of a light-screening agent, or low exposure amount, a cured pattern is complete, clear to develop and high in resolution ratio; the adaptation between the cured pattern and a substrate is excellent; and the photosensitive resin composition has very good application prospects in the aspects of optical colour filters, light spacers, rib barriers and the like.

Description

technical field [0001] The invention belongs to the field of organic chemistry, in particular to a photosensitive resin composition and its application in optical color filters such as color televisions, liquid crystal display elements, solid-state imaging elements and cameras, as well as photospacers (phtospacer) and ribs (rib) applications in etc. Background technique [0002] The photosensitive composition is obtained by adding a photopolymerization initiator to a polymerizable compound having an unsaturated bond, and is polymerized and cured mainly by irradiating energy rays, which plays a decisive role in the production of optical color filters. In recent years, with the improvement of people's requirements for the quality of life, the requirements for the clarity of liquid crystal display screens are also getting higher and higher, which requires that the photosensitive composition used to form the color filter image has high resolution and is compatible with the subst...
