Embodiment

[0149] Hereinafter, the present invention will be further described with reference to examples, but the present invention is not limited to these examples.

Synthetic example 1

[0150] [Synthesis Example 1] Synthesis of Silicone Polymer (A1)

[0151] In a four-necked flask with a stirrer, drop into diethylene glycol methyl ethyl ether as a reaction solvent, trimethylmethoxysilane as a monofunctional silane represented by general formula (1) by the following weight, as Trimethoxymethylsilane and trimethoxyphenylsilane, which are trifunctional silanes represented by the general formula (2), were then added dropwise a mixed solution of 0.19 g of formic acid, 0.08 g of phosphoric acid, and 5.81 g of water. Then, it heated at 80 degreeC for 1 hour, then distilled off for 2.5 hours to remove a low molecular weight component, and then distilled off at 130 degreeC for 2 hours, and obtained the 80 weight% solution of the siloxane polymer (A1). The total of the low boiling point components removed by distillation was 21.07g.

[0153] The above solution was cooled to room temperature (25° C.), a part of the solution was sampled, and the weight avera...

Synthetic example 2

[0154] [Synthesis Example 2] Synthesis of Silicone Polymer (A2)

[0155] Use triethoxymethylsilane instead of trimethoxymethylsilane as the trifunctional silane represented by the general formula (2), except that the following weights are added to the same components as in Synthesis Example 1. 1 The reaction was carried out under the same conditions to obtain an 80% by weight solution of the siloxane polymer (A2). GPC analysis of the siloxane polymer (A2) thus obtained revealed that the weight average molecular weight (Mw) was 4,000. In addition, the number ratio of the methyl group to the phenyl group in the siloxane polymer (A2) was 2.0.

Abstract

Provided are: a material which has high transparency and excellent sputtering resistance and heat resistance, does not undergo cracking, and can be formed into a cured film having a thickness of 10 to 200 μm by the application or printing of the material; and a cured film and a display element, each of which is produced using the material. Specifically, a heat-curable composition comprising a siloxane polymer component and a solvent, wherein the siloxane polymer component contains a siloxane polymer (A), which is a polymer produced by reacting a silane mixture comprising a monofunctional silane represented by general formula (1) with a trifunctional silane represented by general formula (2), in an amount of 90 wt% or more relative to the whole amount of the siloxane polymer component, and a trifunctional silane wherein R represents a C6-10 aryl group in which an arbitrary hydrogen atom may be substituted by a halogen atom is contained as the trifunctional silane represented by general formula (2) in an amount of 30 mol% or more relative to the whole amount of the trifunctional silane. [In formulae (1) to (2), R's independently represent, for example, an alkyl group; and (R')'s independently represent a hydrolysable group.]

Description

technical field [0001] The present invention relates to a thermosetting composition usable for hardened films such as protective films. Background technique [0002] In the manufacturing process of elements such as liquid crystal display elements, there are various chemicals such as organic solvents, acids, and alkali solutions that treat the surface of display elements that are in the process of being manufactured, or when forming wiring electrodes into films by sputtering. A case where the surface of a display element is locally heated to a high temperature. Therefore, in order to prevent deterioration, damage, and deterioration of the surface of various elements, a surface protection film may be provided. Various characteristics that can withstand various treatments in the manufacturing steps as described above are required for the protective film. Specifically, heat resistance, solvent resistance, chemical resistance such as acid resistance and alkali resistance, water...
