Problems solved by technology

[0008] Although fluorine-based or silicon-based surfactants with high surface tension lowering effects are generally used in the related art in order to ensure coatability and planarity, it is disadvantageous that the coating film obtained during the process of adding excess surfactant After curing, the surface energy is significantly lowered to impair the recoating properties in the subsequent process, and the use of surfactants is limited due to various defects caused by foaming in the pipe during the process
In summary, depending on the type of polymer constituting the material, there are cases where surfactants have no effect

Embodiment 1

[0081] 1-1. Thermosetting binder resin

[0082] A monomer composed of 15 parts by weight of 2-tetrahydropyranyl methacrylate, 40 parts by weight of glycidyl methacrylate, 20 parts by weight of methoxydiethylene glycol monomethacrylate and 25 parts by weight of styrene And 200 parts by weight of propylene glycol methyl ether acetate as solvent respectively add in the flask with nitrogen inlet, this flask is heated to 90 DEG C, and in this flask, add 3.0 parts by weight of azobisvaleronitrile (AVN), And maintain this temperature for 9 hours. The reacted resin solution was added dropwise to excess hexane to form a precipitate and vacuum dried to obtain a thermosetting binder resin (A1). The resin (A1) had a weight average molecular weight (Mw) of 12,500 according to polystyrene standards.

[0083] 1-2. Thermosetting resin composition

[0084] 100 parts by weight of the synthesized copolymer (A1) are dissolved in 400 parts by weight of propylene glycol methyl ether acetate ...

Embodiment 2

[0088] Except using methoxytriethylene glycol monomethacrylate instead of methoxydiethylene glycol monomethacrylate, proceed in the same manner as in Example 1-1 to obtain a thermosetting binder resin (A2 ), according to polystyrene standard, its weight average molecular weight (Mw) is 12,900. Using the resin (A2) and proceeding in the same manner as in Examples 1-2 and 1-3, a composition and a cured film were prepared.

Embodiment 3

[0090] Except using methoxyethylene glycol monomethacrylate instead of methoxydiethylene glycol monomethacrylate, proceed in the same manner as in Example 1-1 to obtain a thermosetting binder resin (A3) , according to polystyrene standard, its weight average molecular weight (Mw) is 12,000. Using the resin (A3) and proceeding in the same manner as in Examples 1-2 and 1-3, a composition and a cured film were prepared.

Abstract

The present invention relates: to a composition including water-soluble monomer including an epoxy group-containing ethylenically unsaturated monomer and ethylene epoxide, or an epoxy group-containing ethylenically unsaturated monomer, and acidic content; to a thermosetting binder resin including a water-soluble monomer including an ethylene oxide group; to a thermosetting resin composition including same; and to a hardening layer, to a color filter, and to a device for a liquid crystal display manufactured from same. The thermosetting binder resin of the present invention can greatly improve the coatability of a composition forming a reinforcing layer, can increase the surface energy of a coated protective layer, and can also improve the re-coatability of a protective layer in subsequent processes after same is formed.

Description

technical field [0001] The invention disclosed herein relates to a thermosetting resin composition for LCD color filter protective film, and more particularly, to a thermosetting resin composition capable of forming various good chemical resistances (such as heat resistance, acid resistance, alkali resistance, etc.) ), a thermosetting resin for a cured film having good coatability to a substrate, and good recoating properties for subsequent processing, relates to a cured film formed using the composition, and a liquid crystal display comprising the film. Background technique [0002] A color liquid crystal display is treated with a solvent, an acidic solution, or an alkaline solution during its manufacture, or the surface of the device is partially treated at high temperature when a transparent electrode layer is formed by a sputtering method. Sometimes, when the transparent electrode layer is etched into a desired shape, the above device is exposed to an acidic or alkaline ...
