TECHNICAL FIELD OF THE INVENTION
The present invention relates to a method for producing a processed film having good quality.
[0002]
BACKGROUND OF THE INVENTION
Conventionally, as a continuous production method of a processed film in which a surface coat made of an ultraviolet-curable resin or the like is provided on a transparent film, an ultraviolet-curable resin is sequentially applied to a rotating mold, and a transparent layer is formed on the applied layer. There has been known a method in which a film is sequentially placed in close contact with each other, and then cured by irradiating ultraviolet rays from the transparent film side to bring the cured product into close contact with the transparent film.
[0003]
However, there has been a problem that the transparent film is colored by ultraviolet irradiation or becomes brittle and easily cracked. Coloring of the transparent film causes a reduction in display quality when used as an optical film in a liquid crystal display device, for example. Further, when the transparent film is embrittled, cracking or chipping is likely to occur at the time of lamination during the production of a liquid crystal panel or the like, which causes cracking due to expansion and contraction during heating and cooling.
[0004]
Technical Problems of the Invention
An object of the present invention is to develop a method for producing a processed film of good quality, in which coloring and embrittlement hardly occur in a transparent film.
[0005]
[Means for solving the problem]
The present invention, from the transparent film side to the coating layer of the active energy ray-curable resin provided on the transparent film, irradiates the active energy ray whose wavelength range of the irradiation light is reduced to the curing area of the curable resin, It is intended to provide a method for producing a processed film, which comprises curing a layer.
[0006]
【The invention's effect】
Advantageous Effects of Invention According to the present invention, it is possible to efficiently cure a coating layer of a curable resin by cutting a wavelength region unnecessary for curing, and to disassemble and recombine a transparent film forming material by cutting a light beam with strong damage. And it can be prevented that the transparent film is easily broken due to coloring or embrittlement, and a processed film of good quality can be efficiently obtained. In addition, it is easy to mold and process the coating layer of the curable resin, and it is also possible to obtain a high quality optical film having various surface shapes such as prismatic irregularities with good production efficiency.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
The production method according to the present invention, from the transparent film side to the active energy ray-curable resin coating layer provided on the transparent film, irradiates an active energy ray whose wavelength range of irradiation light has been reduced to the curing area of the curable resin. And curing the coating layer to obtain a processed film. The implementation can be performed using, for example, the apparatus illustrated in FIG.
[0008]
In the apparatus of the figure, the application layer of the active energy ray-curable resin is brought into contact with a processing layer provided on the surface of the mold, and the coating layer is formed through the processing layer of the mold, and the formed layer is formed. The method of irradiating active energy rays to obtain a processed film is shown. In the figure, 1 is a cylindrical roll as a mold, 2 is a processed layer, 4 is a transparent film, 5 is an active energy ray irradiation device, 12 is an active energy ray curable resin, 41 is a processed film, and 3 is a processed film. A nip roll, 6 is a filter, and 7 is a peeling roll. The working layer 2 is formed by attaching a forming die having a forming pattern in a state of dispersing and distributing a large number of fine convex portions 21 to a cylindrical roll.
[0009]
In the above-mentioned apparatus, the nip roll 3 is arranged with a predetermined gap provided around the outer circumference of the cylindrical roll 1 which rotates, and rotates in the opposite direction in conjunction with the rotation of the cylindrical roll. The above gap arrangement can also be achieved by a nip roll having a radius at both ends larger than a radius at the center.
[0010]
According to the nip roll, by arranging the nip roll so as to be in partial contact with the outer circumference of the cylindrical roll through the outer circumference of both ends, the center of the nip roll and the cylindrical roll based on the difference in radius between the both ends and the center. A gap can be formed between them, and the gap can be kept constant by maintaining the contact state, thereby improving the thickness accuracy and the like of the formed processed film.
[0011]
The apparatus is further provided with a means for applying an active energy ray-curable resin 12 comprising a pump 10 and a nozzle 11. The active energy ray-curable resin 12 stored in the tank is sucked up by the pump 10 and It can be supplied continuously through the. Thereby, the active energy ray-curable resin 12 is applied on the transparent film 4.
[0012]
The transparent film 4 to which the curable resin 12 has been applied is placed between the cylindrical roll 1 and the nip roll 3 via a transport means (not shown) so that the coating layer is on the cylindrical roll side, and between the cylindrical roll and the peeling roll. 7 and are sequentially guided. Thereby, the coating thickness of the curable resin is controlled through the gap between the cylindrical roll and the nip roll, and while the transparent film adheres to the outer periphery of the cylindrical roll through the coating layer and moves along the cylindrical roll that rotates axially. The shape of the processing layer 2 is transferred to form a coating layer.
[0013]
Next, the transparent film 4 which is in close contact with the cylindrical roll 1 is irradiated with active energy rays from the transparent film side through the curing means 5 and the filter 6 to cure the curable resin coating layer inside the film. After being formed into the processed film 41, the processed film is peeled off from the cylindrical roll 1 via a collecting means composed of a peeling roll 7 which rotates around the axis, and is wound up by a winding roll (not shown) if necessary.
[0014]
Therefore, the transparent film 4 coated with the active energy ray-curable resin 12 is applied to the gap formed between the outer circumference of the cylindrical roll 1 and the outer circumference of the nip roll 3 by the manufacturing apparatus described above so that the coating layer comes into contact with the cylindrical roll. After passing through the gap to form a coating layer through the processing layer, the active energy ray in which the wavelength range of the irradiation light is reduced from the transparent film side through the filter 6 to the curing range of the curable resin. 5 is applied to cure the coating layer to continuously obtain the processed film 41.
[0015]
Therefore, by the above, from the transparent film side to the coating layer of the active energy ray-curable resin provided on the transparent film, the active energy ray whose wavelength range of the irradiation light is reduced to the curing area of the curable resin is irradiated, and the coating is performed. The layer can be cured to give a processed film.
[0016]
Further, in the above case, the coating layer is brought into contact with a processing layer provided on the surface of a mold formed of a cylindrical roll to form the coating layer via the processing layer of the mold, and the formed layer is irradiated with active energy rays. As a result, a processed film having a cured body to which the surface shape of the processed layer has been transferred can be obtained.
[0017]
Further, in the above case, a step of sequentially applying the active energy ray-curable resin to a predetermined position of the moving transparent film while sequentially moving it using a long transparent film, By providing a step of peeling and recovering the cured body from the mold, a processed film can be manufactured continuously.
[0018]
In the above-described embodiment, the axial rotation of the cylindrical roll 1, the nip roll 3, and the peeling roll 7 may be, for example, when the moving force of the transparent film 4 via the conveying means is insufficient for the axial rotation. A drive source for rotating two or more rolls is used as needed. Further, in the illustrated example, an ultraviolet irradiation lamp is used as the active energy ray irradiation device 5 as a curing means, and therefore, an ultraviolet curing resin is used as the active energy ray curing resin.
[0019]
Cylinder rolls and nip rolls are made of a suitable material such as a metal such as aluminum, nickel, cobalt, copper or steel or alloys thereof, a resin such as a silicone resin or a urethane resin, an epoxy resin or a fluorine resin. Can be formed. It is preferable to use a metal or an alloy from the viewpoint of strength, durability, processing accuracy and the like. The same applies to a peeling roll.
[0020]
The gap between the cylindrical roll and the nip roll is controlled by adjusting the thickness of the processed film, so that the thickness of the transparent film is added to the thickness of the target coat layer. It can be appropriately determined according to the desired thickness of the coat layer. The thickness of the coat layer is generally 1 μm to 1 mm, preferably 2 to 500 μm, particularly 5 to 100 μm, but is not limited to this.
[0021]
The cylindrical roll may be a roll having a smooth surface and a uniform diameter, or a roll having a processed layer for forming a coating layer of an active energy ray-curable resin on the surface. In the former, a coat layer having a smooth surface can be formed, and in the latter, a coating layer having a surface shape corresponding to the processed layer is formed by irradiating active energy rays to the formed layer of the coating layer via the processed layer. To obtain a processed film.
[0022]
In the case where the processing layer is provided, the leveling action of the applied thickness of the resin through the gap with the nip roll effectively contributes to the molding, and the shape transfer of the processing layer can be performed with high accuracy. The gap adjustment by changing the diameter of the rolls can also be achieved by increasing the diameter of both ends of the cylindrical rolls, and the diameters of both the cylindrical rolls and the nip rolls can be changed.
[0023]
The shape provided in the processing layer is arbitrary, for example, an embossing pattern or a fine uneven pattern for the purpose of imparting a light diffusion function, a dot pattern or a porous pattern, a prism pattern or a waveform pattern, a groove pattern or a projection pattern, or the like. An appropriate mold or pattern can be provided according to the intended use of the processed film.
[0024]
Therefore, it is also possible to use a mold formed of a cylindrical roll or the like having on its surface a processed layer having a form in which a large number of fine projections having a rectangular planar shape are dispersed and distributed. The dispersion distribution form of the fine projections is arbitrary. In a general dispersion distribution form, the long side direction of the fine convex portion is parallel to one side, or is inclined at 70 degrees or less, particularly 50 degrees or less, particularly in the range of 0 to 45 degrees.
[0025]
The dimensions of the rectangular fine projections can be appropriately determined according to the purpose of use of the processed film. Generally, the long side length of the rectangle is 10 to 200 μm, preferably 15 to 150 μm, particularly 20 to 100 μm, and the short side length and the height of the projection are 2 to 30 μm, especially 3 to 20 μm, particularly 5 to 15 μm. It is a fine projection.
[0026]
The cross-sectional shape of the fine projection can be determined as appropriate, but is generally a triangle to a pentagon. Further, based on the obtained processed film, a fine convex portion capable of forming a concave portion having a cross-sectional shape having one or two or more inclined surfaces with an inclination angle of 60 degrees or more, particularly 65 to 90 degrees, with respect to the film surface is obtained. .
[0027]
The processed film is arranged, for example, on the viewing side or the back side of the liquid crystal display panel, and a front light mechanism or a backlight mechanism for efficiently changing the optical path of incident light from the side surface or the corner of the panel in the viewing direction. It can be formed and can be preferably used as an optical film for forming a liquid crystal display device which is thin, lightweight, bright and easy to view.
[0028]
In FIG. 2, a form formed by fine projections on the surface of a processing layer provided on a mold formed by a cylindrical roll is transferred, and a planar shape is a processing film 41 having a form in which a large number of fine concaves are dispersed and distributed on the surface. Examples have been given. Reference numeral 42 denotes a fine concave portion.
[0029]
In the above, a processed film (optical film) that is preferable in that incident light from a side surface or the like is emitted with good directivity in a normal direction of a liquid crystal display panel or the like, and a liquid crystal cell is efficiently illuminated to achieve a bright and easy-to-view liquid crystal display. A large number of fine concave portions having an optical path conversion slope having an inclination angle of 35 to 48 degrees, particularly 38 to 45 degrees, and particularly 40 to 43 degrees with respect to the film surface, have a form in which they are dispersed and distributed. The fine concave portions can be formed by dispersing and distributing the fine convex portions on the surface of a mold such as a cylindrical roll.
[0030]
The fine recesses form light emitting means, and may be distributed in parallel or irregularly based on the long side direction. Furthermore, the distribution state may be a pit-like (concentric) arrangement with respect to the virtual center. The occupied area based on the projected area of the light emitting means on the surface of the processed film on which the light emitting means is formed is 1/100 to 1/8, especially 1/50 to 1/10, from the viewpoint of achieving a bright display. Particularly, 1/30 to 1/15 is preferable.
[0031]
In addition, the cross-sectional shape of the fine concave portion may be such that the inclination angle or the like is constant over the entire surface of the processed film, or may be a shape on the processed film in consideration of absorption loss and attenuation of transmitted light due to optical path conversion. For the purpose of achieving uniform light emission, the fine concave portion may be made larger as the distance from the side surface on the light incident side is increased.
[0032]
Further, the pitch may be fine concave portions having a constant pitch, or the pitch may be gradually narrowed as the distance from the side surface on which light is incident increases, so that the distribution density of the fine concave portions may be increased. Further, the light emission on the processed film can be made uniform at a random pitch, and the random pitch is more advantageous than preventing moire due to interference with pixels. Therefore, the light emitting means may be composed of a combination of fine concave portions having different shapes and the like in addition to the pitch.
[0033]
It is preferable that the above-described optical path changing slope in the fine concave portion faces the direction of the light to be incident from the side direction of the liquid crystal cell or the like from the viewpoint of improving the emission efficiency. Therefore, when the linear light source is used, the optical path conversion slope is preferably oriented in a certain direction. In addition, when a point light source such as a light emitting diode is used, it is preferable that the optical path conversion slope faces the direction of the light emission center of the point light source.
[0034]
As described above, the pit-shaped arrangement of the fine concave portions is such that a point light source is disposed on the side surface of the liquid crystal display panel or the like, and the radial incident light from the side direction by the point light source or the transmitted light is transmitted through the optical path conversion slope into the optical path. It is an object of the present invention to convert the processed film so that the processed film emits light as uniformly as possible, and to emit light having excellent directivity in a normal direction to a liquid crystal cell or the like from the processed film with efficient use of light from a light source.
[0035]
Therefore, it is preferable that the pit-like arrangement is performed such that a virtual center is formed on the end face of the processed film or outside thereof so that the point light source can be easily arranged. The virtual center can be provided at one position or at two or more positions with respect to the same or different processed film end faces.
[0036]
In the above, when a coat layer having a groove-shaped or hole-shaped pattern is formed based on a processed layer provided with a mountain-shaped or convex-shaped pattern, a gap between a cylindrical roll and a nip roll is formed by the convex portion. Is more than the sum of the height of the transparent film and the thickness of the transparent film, particularly, 1.1 to 500 times, particularly 1.5 to 200 times, the height of the convex portion. This makes it possible to form a gap required for forming a target coat layer having the concave pattern.
[0037]
The processing layer provided on the surface of the mold such as a cylindrical roll is formed by an appropriate method such as a method of directly forming the mold on the surface of the mold, a method of mounting the mold on the surface of the mold, and a method of using them together. It can be applied to part or all of the surface of the mold. By the way, in the example of FIG. 1, a processing layer having a form in which a large number of the fine projections 21 are dispersed and distributed is fixed to a part of the outer periphery of the cylindrical roll 1 as a flexible flat mold (forming mold) 2 having the form. It is formed by this.
[0038]
The forming die can be formed of an appropriate material exemplified by the above-described cylindrical roll and the like. Incidentally, the formation of a flexible flat mold having a target molding pattern, such as a dispersion distribution form of a large number of fine protrusions, is performed by, for example, first applying a dry etching method using a laser beam to a resin plate to form a target molding pattern. It can be carried out by forming a matrix having corresponding fine concave portions, and applying an electroforming method to the matrix to form a flexible electroforming mold having a target forming pattern composed of fine convex portions. . A mold such as a cylindrical roll having a molding pattern directly formed on the surface can be manufactured by, for example, a cutting method.
[0039]
The thickness of a mold such as a flat plate mold can be appropriately determined according to the dimensions and mechanical strength of a mold such as a cylindrical roll. In particular, as thin as possible within a range that satisfies the required strength, it is preferable from the viewpoint of the fit to the mold surface based on flexibility and the like. If the mold is too thick, the boundary between the mold and the mold generated when the mold is attached to the mold body may reduce the resin releasability, or may easily cause resin residue, which may impair the appearance of the processed film.
[0040]
The general thickness of the mold is 0.02 to 3 mm, preferably 0.05 to 1 mm, particularly 0 to 3 mm based on the thickness of the portion having no convex or concave portion, from the viewpoint of durability and handling properties. .1 to 0.5 mm. The fixing of the molding die to the cylindrical body such as a cylindrical roll can be performed by an appropriate method such as an adhesion method using an adhesive or the like, a jig fixing method using a screw or the like, or a vacuum suction method, and is particularly limited. There is no.
[0041]
Examples of the active energy ray-curable resin applied on the transparent film include, for example, an acrylic resin, a urethane resin, a urethane acrylic resin, an epoxy acrylic resin, an epoxy resin, a silicone resin, and the like, which can be cured by an active energy such as an electromagnetic wave. One or more of these may be used. Above all, it is preferable to use monomers and oligomers which are excellent in fluidity and can form a cured product having excellent transparency.
[0042]
Further, a material which can be cured with an active energy ray having a wavelength equal to or less than the ultraviolet region including an electron beam or the like is preferable to a point such as curing in a short time. Above all, an ultraviolet curable resin that can be cured with ultraviolet light is preferable from the viewpoint of simplification of the apparatus and the like. Particularly, from the viewpoint of reducing damage to a transparent film and preventing coloring due to absorption of a visible light by a photoinitiator, 290 nm is used. An ultraviolet curable resin containing a photoinitiator exhibiting an absorption wavelength peak in a wavelength range of from 380 nm to 380 nm is preferred.
[0043]
The method of applying the active energy ray-curable resin on the transparent film is arbitrary, and an appropriate method can be adopted. Therefore, it can be applied to the transparent film by an appropriate developing method including, for example, a nozzle supply method, a roll coating method, a bar coating method, a doctor blade method and the like as shown in the figure. The application amount can be appropriately determined according to the thickness of the coat layer to be formed and the like.
[0044]
As the transparent film to be coated with the curable resin, an appropriate transparent film having active energy ray transmittance can be used. Incidentally, examples thereof include acrylic resins, polycarbonate resins, vinyl chloride resins, polyester resins such as polyethylene terephthalate and polyethylene naphthalate, cellulose resins such as diacetyl cellulose and triacetyl cellulose, norbornene resins, urethane resins, Examples include films made of polystyrene resins, olefin resins such as polyethylene and polypropylene, polyamide resins, polyimide resins, and epoxy resins.
[0045]
Further, polymer films described in JP-A-2001-343529 (WO 01/37007), for example, (A) a thermoplastic resin having a substituted or / and unsubstituted imide group in a side chain, and (B) a substituted or unsubstituted imide group in a side chain. And / or a transparent film comprising a resin composition containing A and B with a thermoplastic resin having an unsubstituted phenyl group and a nitrile group. Incidentally, specific examples of the resin composition include those containing an alternating copolymer of isobutene and N-methylmaleimide and an acrylonitrile-styrene copolymer. The film can be obtained as an extruded product or a cast film-formed product of such a resin composition.
[0046]
The light transmittance of a transparent film, particularly for an optical film, is preferably 80% or more, more preferably 85% or more. The haze is preferably 2% or less, particularly preferably 1% or less. Further, the refractive index is preferably from 1.45 to 1.70. The thickness of the film is arbitrary, but is generally 500 μm or less, especially 5 to 300 μm, particularly 10 to 200 μm in view of handling properties and strength. With such a thickness, sizing by punching or the like can be easily performed.
[0047]
Depending on the type of the resin, the curing treatment of the coating layer of the resin as a molding layer by transferring the shape of the mold surface based on the fluidity of the active energy ray-curable resin through the processing layer as necessary depends on the type of the resin. One or more suitable devices for irradiating active energy rays such as ultraviolet rays and electron beams can be used. Incidentally, examples of the ultraviolet irradiation lamp include a metal halide lamp and a high-pressure mercury lamp. Among them, a metal halide lamp having excellent luminous efficiency in a wavelength range of 300 nm to 380 nm is preferable.
[0048]
The process of reducing the wavelength range of the irradiation light by the active energy ray to the curing range of the curable resin is to cut out the wavelength light that easily damages the transparent film from the active energy rays emitted from the irradiation device. Aim. The cut wavelength is not particularly limited, but generally, the transmittance of a transparent film is lower in a short wavelength region of 300 nm or less than in a long wavelength region of more than 300 nm, and the absorption of ultraviolet light in the short wavelength region is high. It is advantageous to cut off light having a wavelength of 250 nm or less, especially 290 nm or less, because the influence is large, and the energy is higher for light having a shorter wavelength, and the damage is greater for light having a shorter wavelength.
[0049]
The active energy ray can be cut by an appropriate method. Generally, a method in which a filter 6 is disposed between the active energy ray irradiation device 5 and the transparent film 4 as shown in the figure is adopted. An appropriate filter can be used as the filter according to the cut wavelength, and may be an optical multilayer film.
[0050]
Incidentally, examples of the short-wavelength cut filter include quartz glass based on natural and synthetic properties, blue plate glass based, and Pyrex glass based filters ("Pyrex" is a registered trademark). From the viewpoint of thermal stability, a quartz glass material is preferable. Further, a filter is preferred in which the transmittance of light having a wavelength of 290 nm is 1/10 or less of the transmittance of light having a wavelength of 350 nm. In addition, it is preferable to arrange the filter at a distance from the irradiation device from the viewpoint of durability due to reduction of thermal damage.
[0051]
Irradiation with active energy rays is performed from the transparent film side, and the processed film formed by fixing and integrating the formed coat layer can be peeled and collected from the mold through an appropriate means such as a peeling roll.
[0052]
【Example】
Example 1
According to FIG. 1, a long transparent polyolefin film having a thickness of 70 μm is placed in a gap of 100 μm formed between a cylindrical roll and a nip roll, and an acrylic containing a photoinitiator having an absorption wavelength peak of 360 nm through a pump. While continuously supplying a system-based ultraviolet curable resin to a thickness of about 33 μm, the resin was introduced at a speed of 1.0 m / min through a conveying means, and a metal halide lamp (120 W / (1 cm light, 1 lamp) for 30 seconds (integrated light amount: 1000 mJ) to cure, and the formed film was peeled off via a peeling roll to continuously produce the target product. The filter has a transmittance of light having a wavelength of 290 nm to 1/10 or less of a transmittance of light having a wavelength of 350 nm.
[0053]
Comparative Example A processed film was obtained in the same manner as in Example 1 except that no quartz glass filter was provided.
[0054]
The processed films obtained in the evaluation test examples and the comparative examples were evaluated for coloring by examining the chromaticity ab with a spectral transmittance measuring device (DOT-3, manufactured by Murakami Color Research Laboratory). In addition, the minimum diameter and the elastic modulus (AUTOGRAPF AG-1 manufactured by SIMAZU) for a crack in the breaking test were examined to evaluate the degree of embrittlement.
[0055]
The results are shown in the following table.

[0056]
From the table, it can be seen that the chromaticity of the comparative example is stronger in the yellow direction, and that the example is closer to colorless and transparent. Also, it can be seen that the elastic modulus of the comparative example is larger than that of the comparative example. From the above, it can be seen that a processed film in which coloring is prevented and in which cracking and chipping due to embrittlement hardly occur is obtained in the present invention.
