Problems solved by technology

[0005] However, these conventional base generators cannot achieve both storage stability at room temperature and a temperature close to room temperature and curability at relatively low temperatures when used as a resin composition for forming a cured film.
In addition, properties such as solvent resistance of a cured film formed from a resin composition using a conventional base generator are insufficient.

preparation example Construction

[0159]

[0160] The curable composition is prepared by uniformly mixing [A] compound and [B] polymerizable compound, preferably [C] alkali-soluble resin, [D] solvent, and other optional components. The curable composition is preferably used in a solution state by being dissolved in the [D] solvent, but the solvent may be omitted.

[0161] The solid content concentration (ratio of components other than the solvent in the composition solution) in the curable composition can be set according to the purpose of use, desired film thickness, and the like. The prepared solution of the curable composition may be used after being filtered using a millipore filter having a pore diameter of about 0.05 μm to 0.5 μm or the like.

[0200] Hereinafter, based on an Example, this invention is demonstrated more concretely. The present invention is not limited by these Examples.

[0201] First, the measurement method and evaluation method of the physical properties will be described.

[0202] [ 1 Determination of H-NMR]

[0203] 1 H-NMR (Nuclear Magnetic Resonance, NMR) was measured at 25° C. using a nuclear magnetic resonance apparatus (“JNM-ECS400” (trade name) (400 MHz) of JEOL Ltd.).

[0204] [Measurement of weight average molecular weight Mw]

[0205] The weight average molecular weight Mw is a polystyrene equivalent molecular weight measured using a gel permeation chromatography (GPC) apparatus (Showa Denko's "GPC-101" (trade name)). The measurement with the GPC device uses a combination of "GPC-KF-801", "GPC-KF-802", "GPC-KF-803" and "GPC-KF-804" (the above are trade names, Showa Denko Corporation) The resulting column was used as a GPC column, and tetrahydrofuran (tetrahydrofuran, THF) was used ...

Description

technical field [0001] The present invention relates to a curable composition, a cured film, a method for forming the same, and a compound. Background technique [0002] The curable composition can form a cured film in large quantities and easily through a simple coating process, so it is currently widely used. In particular, radiation-sensitive curable compositions are widely used in photocurable inks, photosensitive printing plates, and the like in addition to materials such as liquid crystal elements and semiconductor elements because the cured film pattern formation is easy. Such a curable composition usually contains a resin and a hardener. [0003] A typical example of the curing agent is a base generator that generates a base by the action of heat or radiation. Using this base generator, the base generated by the action of heat or radiation can be used as a catalyst to chemically modify the resin to harden the resin to form a cured film. In addition, the difference...
