Problems solved by technology

Practice has shown that most traditional acrylate compositions have defects such as poor solubility, low thermal stability, and low photoactivity, and incomplete photocuring, resulting in a high rate of liquid crystal panel residues, serious pollution of the production line, and increased production costs. These factors It can no longer meet the needs of industry development

Embodiment Construction

[0037] 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.

[0038] The technology of preparing RGB, BM and optical spacers by photocuring and photolithography processes using acrylate photocurable compositions is well known to those skilled in the art, and generally includes the following steps:

[0039] i) dissolving the photocurable composition in a suitable organic solvent (such as propylene glycol monomethyl ether acetate and / or ethyl 2-hydroxypropionate) to obtain a liquid composition;

[0040] ii) using a coating machine, such as a spin coater, a wire-wound bar coater, a shaft coater, or a spray coater, to evenly coat the liquid composition on the substrate;

[0041] iii) Pre-baking and drying to remove solvent;

[0042] iv) Attach a mask to the sample for exposure, followed by development to remove unexposed areas;

[0043] v) Perform post-baking to obta...

Abstract

The invention discloses an acrylic ester photocuring composition which comprises a compound shown in the formula (I), serving as a photoinitiator, and a component matched with the photoinitiator. The photocuring composition has great storage stability and high light sensitivity, can be well cross-linked and cured at very low exposure dose, and realizes an excellent curing effect; and a film prepared from the composition has a flat edge without defects, scum is avoided, the whole pattern has good integrity, the resist film hardness is high, and the prepared optical filter has high optical transparency and prevents light leakage.

Description

technical field [0001] The invention belongs to the field of photocuring technology, and in particular relates to an acrylate photocurable composition and its application in liquid crystal display devices such as color filters and photospacers. Background technique [0002] As the core component of a liquid crystal display device, the color filter is composed of red (R), green (G), blue (B), and black pixel materials, and black is made into a matrix to isolate R, G, and B. To prevent cross-color (ie, black matrix BM). In liquid crystal displays, glass or resin transparent spherical particles called spacers (optical spacers) are scattered inside the cell in order to maintain the thickness between the color filter substrate and the thin film transistor. [0003] Acrylic photocurable compositions are widely used to prepare RGB, BM, and optical spacers, and there are many related reports in patent documents, such as CN1337013, CN1424624, CN101052918, CN101118382, CN101025568, e...
