It is preferred to carry out photopolymerization between the film forming step and the stretching step. As a method of forming a film of a composition, for example, a solvent casting method in which a solution containing a composition is washed on a surface of a flat m and a solvent is removed from a hot chamber can be used; The material is extrusion-molded into a film-like melt extrusion method or the like. It is particularly preferable since the solvent casting method can directly form a solution containing a composition. The photopolymerization method includes a method in which the composition 丨 is irradiated with ultraviolet light (uv) and the composition 1 is photopolymerized and cured. Examples of the ultraviolet light generation source include a fluorescent chemical lamp, a black light, a low pressure, a high pressure, a super-pressure mercury lamp, a metal halide lamp, and a solar ray. The irradiation intensity of the ultraviolet light can be always performed at a constant intensity, and the physical properties after curing can be finely adjusted by changing the strength during the curing. In addition, examples of the stretching method include a stretching method by a tenter method, a stretching method by stretching between rolls, and the like. The stretching may be either uniaxial stretching or biaxial stretching, and may be either longitudinal = stretch or twisted stretch. In particular, from the viewpoint of productivity, biaxial stretching and transverse uniaxial stretching are preferred, and transverse uniaxial stretching is particularly preferred. The ratio of the retardation [Re(450)] of the wavelength of light transmitted through the optical film to the wave, the delay [Re(55〇)] of 55〇nm ([Re(45〇)]/[Re(55〇)]) It is derogated as the wavelength dispersion coefficient α, and in order to make the optical film perform the same polarization conversion in a wide wavelength region, it is preferable to have a wavelength dispersion of the optical film 320812 51 200932766 Coefficient α: lower than l. Optical film: Generally, the wavelength of light of the film of the present invention obtained by wavelength dispersion is 2&quot; the phase difference Re(1;) of Cong generally satisfies (4)_&lt;Re(10)) injury (65__, etc., in the whole fine to the visible light In the region, dispersion which rises to the right is displayed, and therefore, uniform polarization conversion can be performed in a wide wavelength region.

Since the optical film of the present invention can perform uniform polarization conversion in a wide wavelength region, it can be used as a phase difference plate such as a λ/2 plate or a λ/4 plate, or a viewing angle enhancement film. In addition, if the optical film is a λ/4 plate, it can be combined with a linear polarizing plate to produce a circularly polarizing plate of a wide wavelength region, and if it is a λ/2 plate, it can be combined with a linear polarizing plate. A polarized light rotating element is formed in a wide wavelength region. Therefore, it can be used for antireflection filters, liquid crystal projectors, and the like in various liquid crystal display devices, cathode ray tubes (CRTs), contact panels, electroluminescence (EL) lamps, and the like.

As described above, the retardation film of the present invention is composed of the above optical film, and can perform the same polarization conversion in a wide wavelength region. [Examples] Hereinafter, the present invention will be described in further detail based on examples. The "^" and "parts" in the examples are % by weight and parts by weight unless otherwise specified.

(Optical Anisotropy) When the polymer main chain is uniaxially aligned by stretching, the direction of the alignment and the direction in which the refractive index is maximized are different (for example, in the case of a cross-linking), optical anisotropy In the case, it has a negative birefringence. ◎In other respects, when the direction of the alignment and the direction in which the refractive index reaches the maximum are almost the same (for example, when the difference between the direction of the alignment and the direction in which the refractive index reaches the maximum is 10 degrees or less), the positive birefringence is obtained. .

At least one monomer (α-2) and a photopolymer (α~3) in the monomer (α-Ιν) are mixed, and three or more functional groups are mixed as needed. It is prepared by a polymerizable compound, a photosensitizer, a leveling agent, a plasticizer, and an organic solvent. 320812 79 200932766 The amount of the organic copolymer to be produced is (4), and the total concentration of (Η) (α-2) is prepared in an amount of 10% by weight or more and 20 to 50% by weight. Preferably, it is prepared as an organic solvent. The same solvent as the organic solvent used in the above polymerization method can be used. (Production of (α 1)) The optical film of the present invention can usually be produced by photo-polymerizing the film thus obtained and photopolymerizing the obtained film. The film formation method of the composition includes, for example, a solvent casting method in which a composition is cast on a smooth surface and a solvent is distilled off; an organic solvent is removed from the composition, and the product is removed by a melt extruder or the like. The obtained copolymerization = a melt extrusion method in which a film shape is formed in extrusion. It is particularly preferable since the solvent casting method can form a film directly into the group. In photopolymerization, ultraviolet light (10) is usually used. As the source of ultraviolet light, a fluorescent chemical lamp, a black light, a low pressure, a high pressure, an ultrahigh pressure mercury lamp, a metal toothed lamp, a solar ray, and the like can be exemplified. Irradiation intensity of ultraviolet light 〇 (four degrees) η row ' can also be finely adjusted by changing the strength during curing. Further, as a method of stretching the obtained film material, for example, a stretching method by a tenter method, a stretching method by light inter-stretching, or the like can be exemplified.

The optical film 'of the present invention thus obtained' usually has a wavelength dispersion coefficient α of less than 1 Å. The phase difference value at the wavelength Vnm of the light transmitted through the optical film generally satisfies the relationship of Re(450)&lt;Re(550)&lt;Re(10)), etc., and shows the dispersion which rises to the right in the visible region of the entire 〇 to ^(10) Therefore, uniform polarization conversion can be performed in a wide wavelength region. Since the optical film of the present invention can perform uniform polarization conversion in a wide wavelength region, it can be used as a phase difference plate such as a λ/2 plate or a /4 plate or a viewing angle enhancement film. In addition, if the optical film is a λ/4 plate, it can be combined with a linear polarizing plate to form a circular polarization of a wide wavelength region = ', and if it is a 1/2 plate, it can be linearly polarized The sheets are combined to form a polarized light rotating element in a wide wavelength region. Therefore, it can be used for various liquid crystal display devices, cathode ray tubes (CRTs), contact panels, anti-reflection filters in electroluminescence (EL) lamps, liquid crystal projectors, and the like. As described above, the phase difference plate of the present invention is composed of the above-described optical film, and can perform the same polarization conversion in a wide wavelength region.

Wavelength dispersion characteristics. (Optical Anisotropy) When the polymer main chain is uniaxially aligned by stretching, the direction in which the alignment direction and the refractive index are maximized are different (for example, in the case of vertical phase intersection, etc.) optical orientation In the case of the opposite sex, it has a negative birefringence. On the other hand, in the case where the direction in which the alignment direction and the refractive index reach the maximum are uniform or nearly uniform (for example, when the difference between the direction of the alignment and the direction in which the refractive index reaches the maximum is 10 degrees or less), the positive birefringence is obtained. . The direction in which the refractive index is maximized is determined by an automatic birefringence meter.
