Description

  The present invention relates to a film composition, a film, an optical film composition, and an optical film.

In recent years, the demand for functional films has increased. For example, photographic support films, surface protective films, flexible substrate films, tape support films, magnetic tape support films, gas barrier films, antistatic films , Heat shield (infrared reflection, infrared absorption) film, ultraviolet absorption film, protective film for glass, interlayer film for laminated glass, antibacterial film, anti-fogging film, conductive film, medical support film, printing support film Etc. (including packaging films for designs).
Among them, optical films such as viewing angle compensation films, polarizing plate protective films, retardation films, antireflection films, and antiglare films are very useful as demand for mobile phones and liquid crystal televisions grows. It is becoming.
For these films, basically, after forming the film composition into a film, a functional material is provided on one or both sides (by coating, vapor deposition, or the like), or a functional material is added to the film composition in advance. It is obtained by this.

An acrylic resin represented by PMMA has excellent optical performance and has been widely applied to various optical materials as an optical isotropic material having high light transmittance, low birefringence, and low retardation. However, in recent years, with the progress of flat displays such as liquid crystal display devices, plasma displays, organic EL display devices, infrared sensors, optical waveguides, etc., there has been a demand for optical transparent polymer materials, particularly optical transparent polymer materials such as films. It is growing. The properties required for a film-like optically transparent polymer material include, first, high transparency and high optical isotropy, and heat resistance is also required.
However, a conventional optical film made of a transparent polymer material for optics does not sufficiently satisfy these characteristics.

  On the other hand, as a thermoplastic resin having both transparency and heat resistance, a lactone ring-containing polymer obtained by subjecting a polymer having a hydroxyl group and an ester group in a molecular chain to a lactone cyclocondensation reaction is disclosed. (Patent Documents 1 to 4). However, since optical isotropy and light resistance cannot be sufficiently exhibited and the mechanical strength is not satisfactory, it has not been conventionally made into a film-like transparent polymer material for optics. Furthermore, with the lactone ring-containing polymer alone, when the content of the lactone ring structure is increased in order to improve heat resistance, the optical isotropy also decreases, and an optical film with low birefringence and low retardation is obtained. It was difficult.

Cellulose acylate films have been widely used as polarizing plate protective films for liquid crystal display devices because of their moderate water permeability and high optical isotropy (low retardation absolute value).
In recent years, with the widespread use of liquid crystal display devices, demands for display performance and durability have increased, and response speeds have been improved, and a wider viewing angle such as contrast and color balance when viewed from an oblique direction with respect to the display image. It has become a problem to compensate with. In order to solve these problems, various liquid crystal modes have been developed, and accordingly, there is an urgent need to develop a retardation film as an optical compensation film for the purpose of compensating the viewing angle corresponding to each mode. .
Furthermore, in addition to the above, thinning of the panel and cost reduction are required for the liquid crystal display device, and there is a method in which the protective film of the polarizing plate used in the liquid crystal display device has the function of the above retardation film. It is starting to be considered.

  On the other hand, with the diversification of display modes of liquid crystal televisions, the required retardation films have also diversified, and as one of them, a retardation film having a negative retardation in the film thickness direction has been desired. For example, in the so-called in-plane switching (IPS) mode in which a lateral electric field is applied to the liquid crystal, birefringence as an optical compensation film is provided between the liquid crystal layer and the polarizing plate as one means for improving the color tone and the viewing angle of black display. It is proposed to arrange an optical compensation material having a birefringence characteristic in which a film having a positive optical axis in the plane of the film and a film having a positive birefringence and a film having the optical axis in the normal direction of the film are combined. (See Patent Document 5).

  As a cellulose acylate film having a negative retardation in the film thickness direction, a method of cooling and dissolving cellulose acylate having a low acyl substitution degree has been proposed (see Patent Document 6). However, in these methods, Rth is not sufficiently reduced, and a method capable of further reducing Rth has been demanded. In addition, in the cellulose acylate film produced by this method, the water permeability and moisture content of the film are large, and the durability of the polarizing plate when used as a protective film for a polarizing plate, particularly the polarizing plate performance under high temperature and high humidity conditions The problem was that the deterioration of the material was large.

  Furthermore, optical film technology will be described in detail. In terms of transparency, many of the above-mentioned acrylate resins and the like are known to be good. However, as an optical film, it is necessary to freely control the optical anisotropy, and in this respect, a single polymer is required. The current situation is that molecular design alone is difficult. For example, for the purpose of improving this, it is important to use a retardation modifier as an additive of the polymer.

  On the other hand, to improve productivity, use a matting agent (adhesion inhibitor) as an additive for the purpose of improving the rollability of the film at the time of manufacture (especially useful in the direct winding process in which lamination is not performed). There are also many. However, these additives are very important for compatibility with the polymer constituting the film, and cause phase separation with the polymer, particularly under high temperature and high humidity conditions, and significantly deteriorate optical properties and film properties. was there.

The problem to be solved by the present invention is to provide a film composition having high affinity with additives such as a matting agent and to provide a film produced from the film composition.
Further, there has been a demand for an optical film that is excellent in transparency and optical controllability (isotropic property, anisotropy), and that does not separate the additive even under high temperature and high humidity conditions, and has no deterioration in optical properties and the like.
That is, another problem to be solved by the present invention is a composition for an optical film having a high affinity with additives such as a matting agent and a retardation adjusting agent, and a desired retardation with a high total light transmittance. And providing an optical film excellent in stability and productivity.

When the film is formed by the T-die method, a T-die is attached to the tip of a known single-screw extruder or twin-screw extruder, and a film that has been extruded into a film can be obtained as a take-up roll. At this time, it is possible to adjust the temperature of the winding roll as appropriate and apply stretching in the extruding direction so that a uniaxial stretching process can be performed. Moreover, it is also possible to add processes, such as sequential biaxial stretching and simultaneous biaxial stretching, by adding the process of extending | stretching a film in the direction perpendicular | vertical to an extrusion direction.

More preferably, it is (glass transition temperature−20) ° C. to (glass transition temperature + 80) ° C. When it is within the above numerical range, a sufficient stretching ratio can be obtained and stable stretching can be performed.

  The draw ratio defined by the area ratio is preferably in the range of 1.1 to 25 times, more preferably in the range of 1.3 to 10 times. When it is smaller than 1.1 times, it is not preferable because it does not lead to improvement of toughness accompanying stretching. If it is larger than 25 times, the effect of increasing the draw ratio is not recognized.

The stretching speed (one direction) is preferably in the range of 10 to 20,000% / min, more preferably in the range of 100 to 10,000% / min.
If it is within the above numerical range, the production cost can be suppressed because it is appropriate to obtain a sufficient stretch ratio, and the stretched film is hardly broken.
In order to stabilize the optical isotropy and mechanical properties of the (optical) film, heat treatment (annealing) or the like can be performed after the stretching treatment.

The tolerance as a product is an absolute value of 60 or more for an optical film to which no modifier is added, and an absolute value of 120 or more for an optical film to which a modifier is added. The results are shown in Table 6 .

<Evaluation of total light transmittance>
The total light transmittance of the obtained stretched film was measured using a turbidimeter NDH-1001DP (manufactured by Nippon Denshoku Industries Co., Ltd.). The results are shown in Table 6 .

<Evaluation of winding property>
The winding property of the obtained stretched film was evaluated according to the following criteria.
○: It can be wound up without sticking in the film production process.
X: Failure occurs due to close contact in the film production process.
The results are shown in Table 6 .

<Evaluation of stability>
A roll-shaped polyvinyl alcohol film having a thickness of 80 μm was continuously stretched 5 times in an aqueous iodine solution and dried to obtain a polarizing film. Two prepared optical films were prepared, and bonded using a polyvinyl alcohol-based adhesive so as to be sandwiched from both sides with a polarizing film in between, to obtain a polarizing plate in which both surfaces were protected by the optical film. At this time, the optical films on both sides were pasted so that the slow axes were parallel to the transmission axis of the polarizing film.
About the produced polarizing plate, polarizing plate durability is obtained by determining the difference between before and after standing for 1,300 hours under the conditions of 60 ° C. and 95% RH for the average value of the transmittance of crossed Nicols from 400 nm to 700 nm. Evaluated. A smaller number is better, and an acceptable level is 0.05 or less. The results are shown in Table 6 .

From the results shown in Tables 5 and 6 , the film composition of the present invention has good dispersibility and dissolution stability of additives such as matting agents and retardation modifiers when used as an optical film composition. The optical film material thus obtained has good optical properties, high-temperature and high-humidity stability, and productivity (winding property).
In particular, from the results shown in Table 5 , the polymer contained in the film composition of the present invention prevents the turbidity of the optical film by dispersing and stabilizing the matting agent. You can understand that they are compatible.

Although the clear mechanism leading to the result is unknown, it is considered that the direct interaction with the additive having the α-hetero-substituted methylacryl group as the main component is important.
That is, in the polymer having an α-heterosubstituted methylacryl group, a substituent composed of a heteroatom substituted at the α-position forms a large number of adjacent weak interaction sites, as if solvated. It is considered that the additive is stably dissolved or dispersed.
The effect of the retardation adjusting agent is said to be greatly exhibited in a polymer having a small free volume and a polymer that is easily compatibilized, and it is considered that the effect is also exhibited in such a polymer.
