Embodiment 1
[0122] In a four-necked flask with a stirrer, 20.0 g of diethylene glycol ethyl methyl ether as a polymerization solvent and Aronix M-402 (trade name, Toagosei Co., Ltd. Co., Ltd.) 9.9 g, 2,4-diphenyl-4-methyl-1-pentene 2.00 g as a chain transfer agent, V-65 (trade name, Wako Pure Chemical Industries, Ltd. ) 0.5 g, and polymerized by heating at 80° C. for 0.5 hours. Next, a solution in which 0.1 g of Silaplane FM-0711 (trade name, Jieenzhi Co., Ltd.) as a monomer was dissolved in 20.0 g of diethylene glycol ethyl methyl ether was dropped for 0.5 hours, and Polymerization was performed by heating at 80° C. for 1.5 hours.
[0123] The polymerization solution was cooled to room temperature to obtain a copolymer (A1). A part of the polymerization liquid was sampled, and the weight average molecular weight was measured by GPC analysis (polystyrene standard). As a result, the weight average molecular weight was 24,000.
[0124] Films were formed on glass substrates and PET subst...
Embodiment 2～ Embodiment 11
[0126] As shown in Table 1, the types of the (meth)acrylate (a) having more than three functions and the compound (B) having a polymerizable double bond were changed, and the copolymer was obtained by the same method as in Example 1 except that ( A2) ~ copolymer (A11). The same evaluation as in Example 1 was performed using these polymerization liquids.
Embodiment 12
[0128]In a four-necked flask with a stirrer, 20.0 g of diethylene glycol ethyl methyl ether as a polymerization solvent and Aronix M-402 (trade name, Toagosei Co., Ltd. Co., Ltd.) 8.9 g, 2,4-diphenyl-4-methyl-1-pentene 2.00 g as a chain transfer agent, V-65 (trade name, Wako Pure Chemical Industries, Ltd. ) 0.5 g, and polymerized by heating at 80° C. for 0.5 hours. Next, 0.1 g of Silaplane FM-0711 (trade name, Jieenzhi Co., Ltd.) as a monomer dissolved in 20.0 g of diethylene glycol ethyl methyl ether and Aronix M- A solution of 1.0 g of 402 (trade name, Toagosei Co., Ltd.) was heated at 80° C. for 1.5 hours to further polymerize.
[0129] The polymerization solution was cooled to room temperature to obtain a copolymer (A12). A part of the polymerization liquid was sampled, and the weight average molecular weight was measured by GPC analysis (polystyrene standard). As a result, the weight average molecular weight was 24,000. The same evaluation as in Example 1 was performe...

Abstract
The present invention provides a thermosetting resin composition, a cured film thereof, a thermosetting hard coat agent, and a display element, wherein the thermosetting resin composition contains a copolymer (C), and the copolymer (C) is made of It is obtained by reacting a macromonomer (A) and a compound (B) having a polymerizable double bond. or the copolymer (C) is obtained by reacting a macromonomer (A), a compound (B) having a polymerizable double bond, and a (meth)acrylic acid ester (a) with more than three functions, and the resulting The said macromonomer (A) is obtained by reacting the raw material containing the trifunctional or more (meth)acrylate (a). The thermosetting resin composition of the present invention can provide a film with high hardness by thermosetting. This film has excellent properties as a protective film.
Description
technical field [0001] The present invention relates to a cured film obtained by heating and curing a thermosetting resin composition and the composition. Background technique [0002] Conventionally, in image display devices such as liquid crystal displays, touch panel displays, and organic electroluminescence (EL) displays, hard coat materials have been required in order to prevent scratches on the surface of the displays. In recent years, the market for laptop computers, mobile phones, and the like using touch panels has been increasing. [0003] Moreover, with the development of information terminals and liquid crystal display components, there is an urgent need for the development of electronic circuits, displays, sensors and other products based on organic materials. Organic materials can be cited as advantages that they can be easily adjusted by chemical design or synthesis with regard to electrical properties, processing characteristics, and other characteristics; a...
