If the concentration of the solid content is 50% or less, the viscosity of the composition does not become too small, and the film thickness of the optical film tends to be unevenly generated.

An optical film can be obtained by applying a solution containing the compound (A) on a support substrate, followed by drying and polymerization.

When a solution containing the compound (A) is applied on a supporting substrate and dried, a non-polymerized film is obtained. When the unpolymerized film exhibits a liquid crystal phase such as a nematic phase, the obtained optical film exhibits birefringence due to monodomain orientation. Since the unpolymerized film is usually oriented at about 0 to 120 캜, preferably at 25 to 80 캜, a supporting substrate which does not necessarily have sufficient heat resistance can be used. Further, since the non-polymerized film is not crystallized even when it is cooled to about 10 to 30 캜 after the orientation, it is easy to handle.

The film thickness can be adjusted by appropriately adjusting the concentration of the compound (A) in the solution containing the compound (A) or the amount of the solution to be coated on the supporting substrate. In the case of a solution in which the amount of the compound (A) is constant, the retardation value (retardation value, Re (?))

Re (?) = D x? N (?) (7)

(Where Re (?) Represents the retardation value at the wavelength? Nm, d represents the film thickness, and? N (?) Represents the birefringence at the wavelength? Nm) In order to obtain Re (?), The film thickness d may be adjusted.

Examples of the application method to the support substrate include extrusion coating method, direct gravure coating method, reverse gravure coating method, CAP coating method and die coating method. A dip coater, a bar coater, a spin coater, or the like.

Examples of the supporting substrate include glass, a plastic sheet, a plastic film, and a light-transmitting film. As the translucent film, polyolefin films such as polyethylene, polypropylene and norbornene-based polymers; Polyvinyl alcohol film; Polyethylene terephthalate film; Polymethacrylic acid ester film; Polyacrylate film; Cellulose ester film; Polyethylene naphthalate film; Polycarbonate film; Polysulfone film; Polyethersulfone film; Polyether ketone films; Polyphenylene sulfide films; Polyphenylene oxide films; And the like.

Even in the process of requiring the strength of the optical film such as the adhering step of the optical film, the transporting step, and the storing step, the use of the supporting substrate can easily treat the optical film without damaging the optical film.

It is preferable that an alignment film is formed on a supporting substrate and then a solution containing the compound (A) is applied on the alignment film. It is preferable that the alignment film has a solvent resistance that is not dissolved in the solution when the solution containing the compound (A) is applied. It is preferable that the alignment film has a heat resistance in a heat treatment for removing the solvent or for orienting the liquid crystal molecules. Further, it is preferable that the alignment film does not cause peeling or the like due to friction during rubbing. Such an orientation film is preferably composed of a composition containing a polymer or a polymer.

Examples of the polymer include a polyamide or gelatin compound having an amide bond in a molecule, a polyimide having an imide bond in the molecule and a hydrolyzate thereof, polyamic acid, polyvinyl alcohol, alkyl modified polyvinyl alcohol, polyacrylamide, And polymers such as sol, polyethyleneimine, polystyrene, polyvinylpyrrolidone, polyacrylic acid or polyacrylic acid ester. These polymers may be used alone or in combination of two or more. It may also be a copolymer of these polymers. These polymers can be easily obtained by chain polymerization, coordination polymerization, ring-opening polymerization, and the like, such as polycondensation such as dehydration polycondensation and deamine polycondensation, radical polymerization, anionic polymerization, cationic polymerization and the like.

These polymers are usually used as a solution dissolved in a solvent. The solvent is not limited. Specifically, water; Alcohol solvents such as methanol, ethanol, ethylene glycol, isopropyl alcohol, propylene glycol, methyl cellosolve and butyl cellosolve; Ester solvents such as ethyl acetate, butyl acetate, ethylene glycol methyl ether acetate,? -Butyrolactone, propylene glycol methyl ether acetate and ethyl lactate; Ketone solvents such as acetone, methyl ethyl ketone, cyclopentanone, cyclohexanone, methyl amyl ketone and methyl isobutyl ketone; Aliphatic hydrocarbon solvents such as pentane, hexane and heptane; Aromatic hydrocarbon solvents such as toluene, xylene and chlorobenzene; nitrile solvents such as acetonitrile; Ether solvents such as propylene glycol monomethyl ether, tetrahydrofuran and dimethoxyethane; Halogenated hydrocarbon solvents such as chloroform; And the like. These organic solvents may be used alone or in combination of two or more.

An alignment film may be formed using a commercially available alignment film material as it is. Commercially available alignment film materials include SunEver (registered trademark; manufactured by Nissan Chemical Industries, Ltd.) and Optimer (registered trademark; manufactured by JSR Corporation).

By using such an orientation film, it is not necessary to control the refractive index by stretching, so that the in-plane unevenness of birefringence becomes small, and a large optical film capable of coping with the enlargement of a flat panel display (FPD) .

As a method of forming the alignment film on the supporting substrate, there can be mentioned a method of coating a solution of a commercially available alignment film material or a compound to be an alignment film material as a solution on the supporting substrate, and thereafter annealing.

Within the above range, the compound (A) or the like can be oriented at a desired angle on the alignment film. If necessary, the alignment film may be rubbed, or the alignment film may be subjected to polarized UV irradiation.

As a method of rubbing the alignment film, there is a method of bringing a rubbing roll with a rotating rubbing cloth into contact with an alignment film carried on the stage and being transported.

The method of laminating the unpolymerized film on the alignment film laminated on such a supporting substrate can reduce the production cost as compared with the method of manufacturing the liquid crystal cell and injecting the liquid crystal compound into the liquid crystal cell, Film production is also possible.

The removal of the solvent may be carried out in parallel with the polymerization reaction. It is preferable to remove most of the solvent before the polymerization reaction from the viewpoint of the film formability.

Examples of the method for removing the solvent include natural drying, air drying, and vacuum drying. The temperature at the time of removing the solvent by heating is preferably 10 to 120 ° C, more preferably 25 to 80 ° C. The heating time is preferably 10 seconds to 60 minutes, more preferably 30 seconds to 30 minutes. If the heating temperature and the heating time are within the above range, a supporting substrate which is not necessarily sufficient in heat resistance can be used as the supporting substrate.

The obtained unpolymerized film is polymerized and cured, whereby a film in which the orientation property of the compound (A) is fixed, that is, a polymerized film is obtained. An optical film having a small refractive index change in the plane direction of the film and a large change in refractive index in the normal direction of the film can be obtained.

The method of polymerizing the unpolymerized film may be appropriately determined depending on the kind of the liquid crystal compound and the compound (A). When the polymerizable group in the compound (A) and the liquid crystal compound is a photopolymerizable group, a photopolymerization method is used, and if the polymerizable group is a thermocomposer, a thermal polymerization method is used. According to the photopolymerization method, the compound (A) having a photopolymerizable polymerizable group and the compound (A) having a photopolymerizable polymerizable group can be obtained by polymerizing a non-polymerized film at a low temperature and widening the range of selection of heat resistance of the support substrate and industrially, It is preferable to use a compound. Also, from the viewpoint of film formability, a photopolymerization method is preferable. The photopolymerization reaction is carried out by irradiating visible light, ultraviolet light or laser light to the unpolymerized film. From the viewpoint of handling, ultraviolet light is particularly preferable. The light irradiation may be carried out at a temperature at which the compound (A) takes a liquid crystal phase. At this time, the polymerized film may be patterned by masking or the like.

In the optical film of the present invention, the adhesion between the supporting substrate and the optical film and the adhesion between the alignment film and the optical film are good, and the production thereof is easy.

The optical film of the present invention is a thin film as compared with a stretched film which gives a retardation by stretching a polymer.

By peeling the supporting substrate, a film in which the alignment film and the optical film are laminated is obtained. Further, the optical film can be obtained by peeling the alignment film.

The optical film thus obtained is excellent in transparency and is used as a film for various displays. The thickness of the optical film differs depending on the retardation value of the optical film as described above. The thickness of the optical film is preferably 0.1 to 10 占 퐉, and more preferably 0.5 to 3 占 퐉 in view of decreasing photoelasticity.
