Problems solved by technology

[0003] Generally, a positive type photoresist whose solubility to an alkaline developing solution is increased by exposing the resist pattern is often used, but the positive type photoresist has the following problems: Naphthoquinone diazide sulfonic acid used as a photosensitive agent produces sulfonic acid, which corrodes the metal wiring
[0012] However, an organopolysiloxane compound that satisfies both hardness and toughness of a cured product and imparts active energy ray curability to an alkali-developable cured film is not yet known.

Embodiment 1-1

[0117] 3-Isocyanatopropyltrimethoxysilane (KBM-9007, manufactured by Shin-Etsu Chemical Co., Ltd.) was added while stirring 348.3 g (3.0 mol) of hydroxyethyl acrylate (manufactured by Osaka Organic Chemical Industry Co., Ltd.) in the reactor. After production) 615.9 g (3.0 mol), the mixture was stirred at 25° C. for 1 hour to obtain 964.2 g (3.0 mol) of a compound represented by the following formula (VI).

[0118] Thereto were added 262.3 g (1.0 mol) of 3-(trimethoxysilyl)propyl succinic anhydride, 487.1 g (3.0 mol) of hexamethyldisiloxane, and 7.2 g of methanesulfonic acid, and added when it became uniform. 147.6 g of ion-exchanged water was stirred at 25°C for 4 hours. 35.9 g of Kaiwa Chemical Industry Co., Ltd. 500SH (manufactured by Kyowa Chemical Industry Co., Ltd.) was put in, stirred for 2 hours, and neutralized. Volatile components such as methanol were distilled off under reduced pressure, followed by pressure filtration.

(where, R 1 and R 5 independently of each other represent a hydrogen atom, methyl, ethyl, n-propyl or isopropyl, R 2 , R 3 and R 6 independently represent a divalent hydrocarbon group having 1 to 10 carbon atoms, R 4 represents a hydrogen atom or a methyl group, n represents an integer satisfying 0≦n≦2, and m represents an integer satisfying 0≦m≦2).

Description

technical field [0001] The present invention relates to an organopolysiloxane compound and an active energy ray-curable composition containing the same, and more specifically, to an organopolysiloxane compound having an alkali-soluble moiety and an active energy ray-curable composition containing the same. Background technique [0002] With the high integration and high speed of LSI, miniaturization of the resist pattern in the manufacturing process of the semiconductor device is required. In addition, in the production of flexible devices represented by organic EL, resist materials having bending resistance and toughness are required. [0003] In general, as a resist pattern, a positive photoresist whose solubility in an alkaline developing solution is increased by exposing it to light is often used. However, a positive photoresist has the following problems: Naphthoquinonediazide sulfonic acid used as a photosensitizer generates sulfonic acid and corrodes metal wiring par...
