Description

Polymeric composition and optical anisotrope using the same

The present invention relates to a polymer having optical anisotropy requiring various optical properties, a polymerizable composition suitable for use as a constituent member of a film, and an optical anisotropy, retardation film, optical anisotropy composed of the polymerizable composition Compensation films, anti-reflection films, lenses, lens sheets, liquid crystal display elements using the polymerizable composition, organic light-emitting display elements, lighting elements, optical parts, polarizing films, colorants, safety signs, and laser light-emitting components , printed matter, etc.

Compounds having a polymerizable group (polymerizable compounds) are used for various optical materials. For example, a polymer having a uniform alignment can be produced by arranging a polymerizable composition containing a polymerizable compound in a liquid crystal state and then polymerizing it. Such polymers can be used for polarizing plates, retardation plates, etc. required for displays. In most cases, in order to satisfy the required optical properties, polymerization rate, solubility, melting point, glass transition temperature, transparency of the polymer, mechanical strength, surface hardness, heat resistance and light resistance, a compound containing two or more kinds is used. A polymerizable composition of a polymerizable compound. In this case, the polymerizable compound used is required to bring good physical properties to the polymerizable composition without adversely affecting other properties.

In order to improve the viewing angle of the liquid crystal display, the wavelength dispersion of the birefringence of the retardation film is required to be small or opposite. As a material for this purpose, various polymerizable liquid crystal compounds having reverse wavelength dispersion or low wavelength dispersion have been developed. However, when a polymerizable compound such as this is added to a polymerizable composition, crystals are precipitated and storage stability is insufficient (Patent Document 1). Again, when When a polymerizable composition is applied to a base material and polymerized, there is a problem that unevenness tends to occur (Patent Documents 1 to 3). When a film with unevenness occurs, such as when it is used in a display, there will be the following problems: the brightness of the screen will be uneven, or the color tone will be unnatural, which will greatly reduce the quality of the display product. Therefore, development of a polymerizable liquid crystal compound having reverse wavelength dispersibility or low wavelength dispersibility that can solve such a problem has been demanded.

Therefore, we are proceeding to develop a polymerizable liquid crystal compound having reverse wavelength dispersibility (Patent Document 4), and it is required to develop a polymerizable compound which, when added to the polymerizable composition to form a polymer, hardens High performance, the durability of the film will not become insufficient.

(Alignment processing)

In addition, the above-mentioned base material may be generally subjected to an alignment treatment or provided with an alignment film so as to align the polymerizable composition when the polymerizable composition solution of the present invention is applied and dried. Examples of the alignment treatment include stretching treatment, rubbing treatment, polarized ultraviolet-visible light irradiation treatment, ion beam treatment, and SiO ₂ oblique vapor deposition treatment on the substrate.

After coating the polymerizable composition, it is dried.

After coating, the liquid crystal molecules in the polymerizable composition of the present invention are preferably aligned uniformly while maintaining a smectic phase or a nematic phase. As one of the methods, a heat treatment method can be mentioned. Specifically, after the polymerizable composition of the present invention is coated on the substrate, it is heated to the N (nematic phase)-I (isotropic liquid phase) transition temperature of the liquid crystal composition (hereinafter referred to as NI transition for short). temperature) or higher, and the liquid crystal composition is brought into an isotropic phase liquid state. After that, slow cooling is performed as necessary to develop a nematic phase. At this time, it is preferable to temporarily maintain the temperature at which the liquid crystal phase is present, so that the liquid crystal phase domain is sufficiently grown to form a monodomain. Alternatively, after coating the polymerizable composition of the present invention on a substrate, a heat treatment such as maintaining the temperature for a certain period of time may be performed within a temperature range where the nematic phase of the polymerizable composition of the present invention is exhibited.

If the heating temperature is too high, the polymerizable liquid crystal compound may be deteriorated due to an unfavorable polymerization reaction. Moreover, if it cools too much, a polymerizable liquid crystal composition may phase-separate, a crystal may precipitate, and a high-end liquid crystal phase such as a smectic phase may be expressed, and an alignment treatment may not be performed.

By performing such a heat treatment, a homogeneous optically anisotropic body with few alignment defects can be produced as compared with a coating method in which only coating is performed.

In addition, if the homogeneous alignment treatment is performed in this way, it is cooled to the lowest temperature at which the liquid crystal phase does not phase separate, that is, cooled to a supercooled state, and polymerized at this temperature in a state where the liquid crystal phase is aligned , the optical anisotropy with higher alignment order and excellent transparency can be obtained.

(aggregation method)

Examples of the method for polymerizing the polymerizable composition of the present invention include a method of irradiating an active energy ray, a thermal polymerization method, and the like. However, since the reaction proceeds at room temperature without heating, a method of irradiating an active energy ray is preferred. Among them, since the operation is simple, the method of irradiating light such as ultraviolet rays is preferable. The temperature at the time of irradiation is set to a temperature at which the polymerizable composition of the present invention can maintain the liquid crystal phase, and in order to avoid the induction of thermal polymerization of the polymerizable composition, it is preferably 30° C. or lower as much as possible. In addition, the polymerizable liquid crystal composition usually exhibits a liquid crystal phase in the range of the C (solid phase)-N (nematic) transition temperature (hereinafter abbreviated as CN transition temperature) to the N-1 transition temperature during the heating process. On the other hand, in the cooling process, in order to obtain a non-equilibrium state thermodynamically, there are cases in which the liquid crystal state is maintained without solidification even below the CN transition temperature. This state is called a supercooled state. In the present invention, the liquid crystal composition in the supercooled state is also included in the state in which the liquid crystal phase is maintained. Specifically, it is preferable to irradiate ultraviolet light with a wavelength of 390 nm or less, and it is preferable to irradiate light with a wavelength of 250 to 370 nm. However, when the polymerizable composition is decomposed by ultraviolet light of 390 nm or less, it may be preferable to perform the polymerization treatment with ultraviolet light of 390 nm or more. This light is preferably diffused and unpolarized light. The ultraviolet irradiation intensity is preferably in the range of 0.05mW/cm ² to 10W/cm ² . Particularly preferred is the range of 0.2mW/cm ² ~2W/cm ² . When the ultraviolet intensity is less than 0.05 mW/cm ² , it takes a lot of time to complete the polymerization. On the other hand, if the intensity exceeds 2 W/cm ² , the liquid crystal molecules in the polymerizable composition tend to be photodecomposed, or there is a possibility that a large amount of heat of polymerization is generated, the temperature during the polymerization rises, and the polymerizable liquid crystal molecules The order parameter changes, and the retardation of the film after polymerization is abnormal.

Moreover, the ultraviolet irradiation amount is preferably in the range of 10mJ/cm ² -20J/cm ² , more preferably 50mJ/cm ² -10J/cm ² , particularly preferably 100mJ/cm ² -5J/cm ² .

If a mask is used to polymerize only a specific part by irradiating ultraviolet rays, and then applying an electric field, a magnetic field or temperature to change the alignment state of the unpolymerized part, and then polymerizing the unpolymerized part, it is also possible to obtain products with different properties. Optical anisotropy of a plurality of regions in the alignment direction.

In addition, when using a mask to polymerize only a specific part by irradiating ultraviolet rays, an electric field, a magnetic field, or a temperature is applied to the polymerizable liquid crystal composition in an unpolymerized state in advance to control the alignment, and in this state, the self-mask is released from the mask. It is also possible to obtain an optically anisotropic body having a plurality of regions having different alignment directions by irradiating light to polymerize it.

The optical anisotropic body obtained by polymerizing the polymerizable liquid crystal composition of the present invention may be used as an optical anisotropic body by peeling from a substrate, or it may be used directly as an optical anisotropic body without being released from the substrate. In particular, since it is difficult to contaminate other members, it is useful when used as a substrate to be laminated or bonded to other substrates.

In order to stabilize the solvent resistance or heat resistance of the obtained optical anisotrope, the optical anisotropic body may also be subjected to heating aging. In this case, it is preferable to heat above the glass transition point of the said polymer film. Usually, it is preferably 50 to 300°C, more preferably 60 to 200°C, and particularly preferably 80 to 150°C.
