[0164] Method for preparing the composition

[0165] The composition of the present invention is preferably prepared by uniformly dissolving or dispersing the above-mentioned components in an appropriate solvent.

[0166] Examples of such solvents include alcohols, ethers, glycol ethers, ethylene glycol alkyl ether acetates, diethylene glycol monoalkyl ethers, diethylene glycol dialkyl ethers, propylene glycol monoalkyl ethers, propylene glycol Alkyl ether acetate, propylene glycol alkyl ether propionate, aromatic hydrocarbons, ketones, esters, etc.

[0167] As specific examples of these solvents, the following can be enumerated respectively:

[0168] As alcohol, for example, methanol, ethanol, etc. can be cited;

[0169] Examples of ethers include tetrahydrofuran and the like;

[0170] As glycol ethers, for example, diethanol monomethyl ether, ethylene glycol monoethyl ether, etc.;

[0171] Examples of glycol alkyl ether acetate include methyl cellosolve acetate, ethyl c...

Embodiment

[0207] Hereinafter, the present invention will be described more specifically by giving examples of synthesis and examples, but the present invention is not limited to the following examples.

[0208] (A) Synthesis of polyorganosiloxane

Synthetic example 1

[0210]Add 27.24g of methyltrimethoxysilane (MTMS), 49.28g of 2-(3,4-epoxycyclohexyl)ethyltrimethoxysilane in a reaction vessel equipped with a stirrer, thermometer, dropping funnel, and reflux cooling pipe (ECETS), 12.02 g dimethyldimethoxysilane (DMDS), 749.2 g methyl isobutyl ketone (MIBK), 12.65 g triethylamine, mixed at room temperature. Then, 90 g of deionized water was dropped from the dropping funnel over 30 minutes, and then reacted at 80° C. for 4 hours while mixing under reflux. After the reaction, the organic layer was taken out and washed in a 0.2% by weight aqueous solution of ammonium nitrate until the washed water became neutral, and then the solvent and water were distilled off under reduced pressure to obtain polyorganosilicon which was a viscous transparent liquid. oxane.

Abstract

To provide a composition to be used suitably for forming a protective film for an optical device, from which a highly-planarity hardened film, which has high surface hardness and various superior resistances such as heat resistance, pressure resistance, acid resistance, alkali resistance and sputtering resistance, can be formed even on a substrate having an uneven surface, and to provide the protective film. This composition for forming the protective film of a color filter contains polyorganosiloxane, carboxylic anhydride and an agent from which an acid is generated by heating or photoirradiation. The polyorganosiloxane has no more than 1,600 g / mol epoxy equivalent.

Description

technical field [0001] The present invention relates to a composition used as a material for a protective film. More specifically, it relates to a composition suitable as a material for forming a protective film for a color filter for a liquid crystal display (LCD) and a color filter for a charge-coupled device (CCD), and a protective film formed from the composition . Background technique [0002] In the manufacturing process of optical devices such as LCDs and CCDs, display elements are dipped in solvents, acid or alkaline solutions, etc., and when wiring electrode layers are formed by sputtering, the surface of the elements is partially exposed to high temperatures. Therefore, in order to prevent the element from deteriorating or being damaged by such treatments, a protective film including a thin film resistant to these treatments is provided on the surface of the element. [0003] Such a protective film is required to have the following properties: high adhesion to th...
