Problems solved by technology

[0004] 1. It is easy to expose to light and cause a decrease in the contrast value of the panel;
[0005] 2. Insufficient mechanical strength resulting in insufficient panel strength; and
[0006] 3. It is easy to flow freely or agglutination occurs, which makes the inhomogeneity of the gap cause the unexpected color change of the panel
[0017] Due to the relatively high hardness requirements of gap control materials, the above resins, while providing some properties, do not fully meet the requirements of resins for gap control material applications

Embodiment

[0058] the term:

[0059] LAH: lithium aluminum oxide ("lithium aluminum hydride")

[0060] BQDCPOH: 1, 4, 4a, 5, 8, 8a, 9, 9a, 10, 10a-decahydro-1, 4: 5, 8-dimethyl bridge-9, 10-diol ("1, 4, 4a , 5,8,8a,9,9a,10,10a-decahydro-1,4:5,8-dimethanoanthracene-9,10-diol")

[0061] Preparation of benzoquinone-cyclopentadiene adduct:

[0062] (1) Freshly prepared cyclopentadiene (26.4 g, 0.4 mol) was added to a solution of p-benzoanthracene (21.6 g, 0.2 mol) in ethanol (200 mol), and the mixture was stirred for half an hour. The resulting colorless solid was filtered and washed with cold ethanol to obtain almost completely reacted dicyclopentadiene-benzoquinone adduct (BQDCP).

[0063] (2) Take the aforementioned product (24 grams, 10 moles) and add LAH (4 grams, 100 moles) in ether (200 milliliters) solution, after reflux reaction for 8 hours, terminate the reaction with aqueous sodium hydroxide solution to obtain the diol product (BQDCPOH).

[0064] (3) Add 6 grams of sodium hyd...

Abstract

This invention provides a resin compound as shown in formula I, wherein R1, R2, R3, R4 and R5, and a, b, c, d, e, f and g are defined in the invention. This invention also provides a photoresist composition containing the resin compound.

Description

technical field [0001] The invention relates to a resin compound containing benzoquinone-cyclopentadiene adduct and a photoresist composition containing the resin compound. The photoresist composition of the present invention has properties such as high resolution and the ability to be developed in an alkaline aqueous solution, and is suitable for pattern conversion, so it can be applied to flat panel displays and photoelectric lithography processes. Background technique [0002] Liquid crystal display has the advantages of small size, light weight, low voltage drive, low power consumption, easy to carry, and does not occupy space. Its products have a wide range of applications, from daily life to high-level industrial applications. Calculators, televisions, communication products, medical equipment, air transport, industrial equipment, military special purposes, etc., make high-quality liquid crystal displays gradually replace traditional color picture tubes. [0003] The ...
