METHOD FOR PRODUCING ESTER GROUP-CONTAINING COMPOUND
-
Paragraph 0227; 0228, (2019/03/08)
The present invention provides a novel method for producing an ester group-containing compound and a derivative produced using the compound as a synthetic intermediate. The invention also provides a polymerizable composition containing the compound obtained by the production method and a film-shaped polymer obtained by polymerizing the polymerizable composition. The present invention is a method for producing an ester group-containing compound, the method including a mixing step of mixing a condensing agent, a Bronsted acid, a carboxylic acid, and a phenol or an alcohol to prepare a reaction mixture. The Bronsted acid selected is other than the condensing agent, the carboxylic acid, and the phenol.

Paragraph 0140-0154, (2018/02/03)
In light of requests to reduce or reverse the wavelength dispersion of the birefringence of a phase-retardation film in order to increase the viewing angle of a liquid crystal display, the present invention provides a polymerizable compound that reduces, for example, the likelihood of crystals precipitating in a polymerizable composition including the polymerizable compound and enables the polymerizable composition to have high preservation stability and a polymerizable composition including the polymerizable compound which reduces the likelihood of inconsistencies being formed in a film-like polymer produced by polymerizing the polymerizable composition. Another object of the present invention is to provide a polymer produced by polymerizing the polymerizable composition and an optically anisotropic body including the polymer.

Paragraph 0105; 0114, (2018/11/21)
The present invention provides a compound represented by the general formula (I), and a polymerizable composition containing the compound. When the polymerizable composition containing the compound represented by the formula (I) is used to form a filmy product, the resulting filmy product exhibits less change over time in phase difference and reverse wavelength dispersion and when the filmy polymer is irradiated with UV light, peeling from a substrate is unlikely to be caused. Further, the invention provides a polymer obtained through polymerization of the polymerizable composition and an optically anisotropic body obtained using the polymer.

Paragraph 0382; 0383; 0384; 0385, (2015/07/02)
A polymerizable compound has a practical low melting point, excellent solubility in a general-purpose solvent, and can produce an optical film at low cost, exhibits low reflected luminance, and achieves uniform conversion of polarized light over a wide wavelength band, an optically anisotropic article. A carbonyl compound is useful as a raw material for producing the polymerizable compound. (In the formula (I), Y1 to Y8 represent —C(═O)—O—, G1 and G2 represent a C1-20 divalent linear aliphatic group, Z1 and Z2 represent a C2-10 alkenyl group that is unsubstituted, or substituted with a halogen atom, Ax represents a C2-30 organic group with at least one aromatic ring, Ay represents a hydrogen atom or C1-20 alkyl group, A1 represents a trivalent aromatic group, A2 and A3 represent a C3-30 divalent alicyclic hydrocarbon group, A4 and A5 represent a C6-30 divalent aromatic group or the like, and Q1 represents a hydrogen atom.)
