Problems solved by technology

[0008] Forming such a protective mold is to use a thermosetting composition that has the advantage of forming a high-hardness protective film with a simple method. However, as a protective film resin composition for exerting the above-mentioned properties, it usually has A highly reactive cross-linking group or catalyst that makes it form a strong cross-link, therefore, there is a problem that the shelf life of the composition itself is extremely short, and handling is very troublesome
In other words, not only the coatability of the composition itself deteriorates over time, but frequent maintenance and cleaning of the coater are also necessary, which is troublesome in operation
[0009] After satisfying the general performance requirements as a protective film such as transparency, a protective film satisfying the above-mentioned properties can be easily formed, and a material excellent in storage stability as a composition is not yet known.
[0010] In addition, Patent Document 3 discloses a thermosetting composition containing a latent carboxyl compound used in paints, inks, adhesives, and molded products, but there is no disclosure on the protective film of color filters.

[0130] Preparation of resin composition

[0131] The resin composition of the present invention is prepared by preferably dissolving or dispersing the above components in an appropriate solvent. As a solvent, it is preferable to use a substance which dissolves or disperses each component of the composition but does not react with each component.

[0132] Examples of such solvents include alcohols, ethers, glycol ethers, glycol alkyl ether acetates, diethylene glycol monoalkyl ethers, diethylene glycol dialkyl ethers, Propylene glycol monoalkyl ethers, propylene glycol alkyl ether acetates, propylene glycol alkyl ether propionates, aromatic hydrocarbons, ketones, esters, etc.

[0133] As specific examples of these, such as:

[0134] As alcohols, such as methanol, ethanol, benzyl alcohol, etc.;

[0135] As ethers, such as tetrahydrofuran, etc.;

[0136] As glycol ethers, such as: ethylene glycol monomethyl ether, ethylene glycol monoethyl ether, etc.;

[0137] As glycol a...

Synthetic example

[0167] Synthesis examples and examples are given below to describe the present invention more specifically, but the present invention is not limited to the following examples.

[0168] Copolymer Preparation

Synthetic example 1

[0170] Add 5 parts by weight of 2,2'-azobis-isobutyronitrile and 200 parts by weight of propylene glycol monomethyl ether acetate into a flask equipped with a cooling tube and a stirrer. Next, 70 parts by weight of glycidyl methacrylate (GMA) and 30 parts by weight of styrene (ST) were added, and stirring was gradually started after nitrogen substitution. 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 33.1% by weight.

Abstract

The invention provides a combination can form high smoothness cured films on a base, even the base surface is low smooth, and suits for forming optical instrument protective films have kinds of excellent characters such as high transparence and surface rigidity, heat and pressure resistance, acidity resistance, alkalescence resistance, spray resistance etc., and has good reserve stability. The resin combination of the invention includes (A) (a1) polymerized unsaturated compounds containing oxiranyl or oxetanyl and (a2) other polymerized unsaturated compounds copolymer except that of (a1),(B) (b1) polymerized unsaturated compounds polymer containing acid anhydride and or (b2) anhydride which containing polycarboxylic acid anhydride, and (C) compounds have framework structure of said formula (1) and or curing accelerant for compounds having framework structure of said formula (2).

Description

technical field [0001] The present invention relates to a resin composition, a method for forming a color filter protective film using the resin composition, and a color filter protective film. More specifically, it relates to a resin composition suitable as a material for producing a color filter protective film for a liquid crystal display device (LCD) and a charge-coupled device (CCD), and a protective film formation using the resin composition Method and protective film made of this resin composition. Background technique [0002] Radiation devices such as LCDs and CCDs are subjected to display element immersion treatment with solvents, acidic or alkaline solutions, and the like in the manufacturing process. Also, when the wiring electrode layer is formed by a sputtering device, the surface of the device is partially exposed to high temperature. Therefore, in order to prevent the element from deteriorating or being damaged due to such treatments, a protective film form...
