Embodiment 1

[0686] -Preparation of photosensitive composition-

[0687] Based on the following composition, the photosensitive composition was prepared.

[0688] [Composition of Photosensitive Composition Solution]

[0689] ・Ripoxy PR-300, concentration 67%, manufactured by Showa High Molecular Co., Ltd.... 50 parts

[0690] ・Ripoxy SPC-2X, concentration 60%, manufactured by Showa High Molecule Co., Ltd.... 30 parts

[0691] ・Dipentaerythritol hexaacrylate (DPHA, manufactured by UCB Chemicals)...20 parts

[0692] ·Methyl ethyl ketone…100 parts

[0693] ・Oxime compound (photopolymerization initiator) represented by the following structural formula (5)...2 parts

[0694] ・1-Chloro-4-propoxythioxanthone (sensitizer)…1 part

[0695] The above composition was mixed and stirred to prepare the photosensitive composition solution of Example 1. Moreover, all operations are performed under yellow light.

[0696] Structural formula (5)

[0697] However, in the above structural formula (5),...

Synthetic example 1

[0700]A mixed solution of 6-methoxy-1-tetralone (10 g), hydroxylamine hydrochloride (6 g), potassium acetate (10 g), and ethanol (100 mL) was heated and stirred at 100° C. for 1 hour. After confirming the disappearance of the raw material by TLC, 200 mL of water was added to precipitate crystals. The precipitated crystals were filtered out and recrystallized from 80 mL of acetonitrile to obtain 10.0 g of an oxime compound as a material.

[0701] The 1H-NMR spectrum of above-mentioned material oxime compound (300MHz, CDCl 3 ) is δ: 1.8(q, 2H), 2.6-2.7(m, 4H), 3.8(s, 3H), 6.7-6.8(m, 2H), 7.8(d, 1H).

[0702] After cooling a mixed solution of the obtained material oxime compound (2.0 g), pyridine (10 g), and tetrahydrofuran (10 mL) to 0° C., methyl chloroformate (1.5 g) was added dropwise at the same temperature. After raising the temperature to room temperature, it was stirred for 2 hours. After confirming the disappearance of the raw material by TLC, it was added to 60 mL of...

Embodiment 2

[0714] In Example 1, except that the oxime compound represented by the structural formula (5) was changed to the oxime compound represented by the following structural formula (2), a photosensitive composition was prepared in the same manner as in Example 1, and prepared in the same manner as in Example 1. The photosensitive layer and laminate are exposed and developed.

[0715] In addition, exposure sensitivity and temporal changes in sensitivity were evaluated by the same method as in Example 1. The results are shown in Table 1.

[0716] Structural formula (2)

[0717] The oxime compound represented by the said structural formula (2) was synthesize|combined by the method similar to the said synthesis example 1 except having used methyl chloroformate as 2-methacryl chloride in the said synthesis example 1.

[0718] Furthermore, the oxime compound represented by the above structural formula (2) 1 H-NMR spectrum (300MHz, CDCl 3 ) is δ: 1.3(d, 6H), 1.9(q, 2H), 2.7-2.8(m, 3...

Abstract

Disclosed are: an oxime compound represented by the general formula (1); a photosensitive composition for which the oxime compound is used as a photopolymerization initiator; a method for producing acolor filter by using the photosensitive composition; and a color filter produced by the method. (1) wherein R<1> represents a hydrogen atom, an acyl group which may have a substituent, an alkoxycarbonyl group, or an aryloxycarbonyl group; R<2>'s independently represent a halogen atom, an alkyl group, an aryl group, an alkyloxy group, an aryloxy group, an alkylthio group, an arylthio group, or anamino group; m represents an integer of 0 to 4, provided that, when m is 2 or greater, the R<2>'s may together form a ring; and A represents a 4-, 5-, 6- or 7-membered ring.

Description

technical field [0001] The present invention relates to an oxime compound, a photosensitive composition using the oxime compound as a photopolymerization initiator, a method for producing a color filter using the photosensitive composition, a color filter produced by the above-mentioned production method, and a photosensitive composition using the oxime compound. A liquid crystal display element incorporating the above-mentioned color filter. Background technique [0002] Conventionally, any oxime ester derivatives are known as photopolymerization initiators that generate active radicals by the action of light to initiate polymerization of monomers (see Patent Documents 1 to 4 and 8). [0003] On the other hand, in the photopolymerization technology, the necessity of a photopolymerization initiator having high photopolymerization reactivity and being easy to handle is gradually increasing. In addition, in order to obtain high-quality products, the requirements for photopoly...
