[0322]
[0323] The curable resin composition can be prepared by mixing [A] polymer, [B] solvent, [C] polymerizable compound, [D] radical polymerization initiator, [E] acid generator , [F] The polymer and other optional components are uniformly mixed, preferably filtered through a membrane filter of about 0.2 μm. Preferably, the curable resin composition is used in a solution state by dissolving it in an appropriate solvent.
[0324] Since the said curable resin composition can form the cured film excellent in adhesiveness and transparency, it can be used suitably for formation of the cured film for display elements used as an interlayer insulating film, a protective film, or a spacer, for example.
[0325]
[0326] The cured film for display elements of this invention is formed from the said curable resin composition. Since the said cured film for display elements is formed from the said curable resin composition, it is excellent in adhesiveness and transparency, For exa...
Embodiment
[0345] Hereinafter, although this invention is demonstrated concretely based on an Example, this invention is not limited to these Examples.
[0346] [Mw and Mn]
[0347] In the following synthesis examples, Mw and Mw / Mn of the [A] polymer were measured by gel permeation chromatography (Gel Permeation Chromatography, GPC) using the following measurement apparatus and measurement conditions.
[0348] Measuring device: Showa Denko "GPC-101"
[0349] Determination conditions:
[0350] GPC column: "GPC-KF-801", "GPC-KF-802", "GPC-KF-803" and "GPC-KF-804" of Showa Denko Co., Ltd. are used in connection.
[0351] Mobile phase: tetrahydrofuran

Synthetic example 1
[0353] [Synthesis Example 1] (Synthesis of Compound (HC-1))
[0354] In a 5L reactor equipped with a stirrer and a dropping funnel, 65.1g (0.5mol) of 2-hydroxyethyl methacrylate, 59.3g (0.75mol) of pyridine and 500mL of dichloromethane were put into the reactor, and the reaction was carried out under nitrogen. While cooling the vessel to 0°C, 76.18 g (0.6 mol) of 3-chloropropionyl chloride was added dropwise from the dropping funnel, and then reacted at 0°C for 2 hours with stirring. The obtained reaction solution was washed successively with aqueous sodium bicarbonate solution and saturated brine, concentrated under reduced pressure, and purified by silica gel column chromatography to obtain 83.4 g of a compound represented by the following formula (HC-1) ( Yield 76%).
