Embodiment

[0235] Hereinafter, although an Example and a comparative example are illustrated and this invention is demonstrated more concretely, this invention is not limited to these Examples.

Synthetic example 1

[0237] In the flask equipped with cooling tube and stirrer, drop 7 parts by weight of 2,2'-azobis(2,4-dimethylvaleronitrile), 200 parts by weight of propylene glycol monomethyl ether acetate. Then drop into 5 parts by weight styrene, 20 parts by weight methacrylic acid, 25 parts by weight methacrylic acid tricyclic [5.2.1.0 2，6 ]decane-8-yl ester, 25 parts by weight of 3-(methacryloyloxymethyl)-3-ethyl oxetane, 20 parts by weight of tetrahydrofurfuryl methacrylate, 5 parts by weight After replacing 1,3-butadiene with nitrogen, start stirring slowly. The temperature of the solution was raised to 70°C, and the temperature was maintained for 5 hours to obtain a polymer solution containing the copolymer [A-1]. The solid content concentration of the obtained polymer solution was 30.0% by weight, and the weight-average molecular weight of the polymer was 18,000 (the weight-average molecular weight was polyphenylene as measured by GPC (Gel Permeation Chromatography) HLC-8020 (manufa...

Synthetic example 2

[0239] In a flask equipped with a cooling tube and a stirrer, 7 parts by weight of 2,2'-azobis(2,4-dimethylvaleronitrile) and 200 parts by weight of diethylene glycol ethyl methyl ether were added. Then drop into 5 parts by weight styrene, 20 parts by weight methacrylic acid, 25 parts by weight methacrylic acid tricyclic [5.2.1.0 2，6 ] Decane-8-yl ester, 25 parts by weight of glycidyl methacrylate, 20 parts by weight of tetrahydrofurfuryl methacrylate, 5 parts by weight of 1,3-butadiene, after replacing with nitrogen, start to slowly Stir. The temperature of the solution was raised to 70°C, and the temperature was maintained for 5 hours to obtain a polymer solution containing the copolymer [A-2]. The solid content concentration of the obtained polymer solution was 31.0% by weight, and the weight-average molecular weight of the polymer was 20,000 (the weight-average molecular weight was polyphenylene as measured by GPC (Gel Permeation Chromatography) HLC-8020 (manufactured by ...

Abstract

A photosensitive resin composition with enough process range to prevent the contamination of the baking oven and photo cover film from sublimation of the photo polymeric initiator, and having the nature of tight annealing, transparency and thermal resisting of which the protection film and the compression of which spacer material. The photo polymeric initiator composed of: [A](a1) ethylene unsaturated carboxylic acid and / or ethylene unsaturated carboxylic acid anhydride, and another polymer of ethylene unsaturated compound; [B]polymeric compound with ethylene unsaturated bond; and [C] a photo polymeric initiator consisting of the compound presented as following formula(1): wherein, n is integer of 2~12, R1 represent H, hydroxyl group or any one group with structure represented (I), (II) and (III); R2 of (III) is C1~C12 alkyl, C3~C8 cycloalkyl or phenyl group (wherein which could be substituted by any one of at least one or more C1~C6 alkyl, C1~C6 alkyloxy),

Description

technical field [0001] The present invention relates to a photosensitive resin composition, a protective film for a liquid crystal display panel, a separator, and a liquid crystal display panel having them. A photosensitive resin composition as a material for a protective film and a separator, a protective film for a liquid crystal display panel formed from the composition, a separator, and a liquid crystal display panel having the protective film and the separator. Background technique [0002] Radiation devices such as LCDs and CCDs dip display elements with solvents, acids, or alkali solutions during their manufacturing process, and when wiring electrode layers are formed by sputtering, the element surfaces are locally exposed to high temperatures. Then, in order to prevent deterioration or damage of elements due to such treatments, a protective film formed of a thin film resistant to these treatments is provided on the surface of the elements. [0003] Such a protective...
