Description

  The present invention provides a light-reactive composition for a color-splitting light-transmitting structure, which has good floating properties and can be effectively used after film formation, and a color-splitting light-transmitting structure using the light-reactive composition. And a method for manufacturing a color-splitting light-transmitting structure.

  Conventionally, colored layers and transparent layers in a color-splitting light-transmitting structure have been manufactured by a projection exposure type pattern transfer method. A film forming step of forming a film (hereinafter, may be simply referred to as a photoreactive compound) on the core material is performed. Generally, in this film forming step, a liquid dropping type film forming method is used. In the film forming method by the liquid dropping type film forming method, an appropriate amount of a photoreactive compound is dropped on a fixed core material, and then the core material is rotated. This is a method in which the photoreactive composition is spread throughout and the photoreactive composition is cured. In the film forming method by such a liquid dropping type film forming method, the amount of the photoreactive compound actually cured on the core material is about several percent of the amount of the photoreactive compound dropped on the core material. It is. That is, the remaining light-reactive composition jumped out of the core material due to centrifugal force, and the light-reactive composition jumped out of the core material was collected as waste liquid and disposed of as industrial waste. This is because when the photoreactive compound jumps out of the core material, it is in the form of fine particles, so it adsorbs with moisture and dust in the atmosphere and is collected from the influence of such moisture and dust. This is because the change in the liquid properties of the photoreactive composition after the treatment is not negligible. In addition, with respect to a material suspended by a method such as a colored layer such as a colored layer, there is a problem that bonding or the like occurs.

  The cause of these bonds and the like includes the presence of alcoholic free radicals in the polymer. The photoreactive composition usually contains a polymer, a monomer, an initiator and the like, and forms a film by polymerizing these materials by exposure. At this time, a carbon-carbon double bond may be introduced into the side chain of the polymer from the viewpoint of improving the film strength or the like by contributing the polymer to the polymerization. In such a case, a carbon-carbon double bond is usually introduced into a side chain by opening the epoxy group of a compound having an epoxy group. At this time, an alcoholic free radical is simultaneously introduced. . However, the alcoholic free radicals in such a polymer may form a hydrogen bond or the like with water molecules when the photoreactive composition absorbs moisture, so that the polymer or the colored particulate matter is bonded. It is thought to be the cause.

  Such a situation in which most of the photoreactive compound is discarded without being effectively used is not preferable from the viewpoints of cost reduction, effective use of resources, material efficiency, environmental pollution by waste liquid, and the like.

  Therefore, as a method of effectively utilizing such a photoreactive composition, for example, Patent Document 1 discloses a viscosity adjusting tank to which a waste liquid of the photoreactive composition is supplied, and a medium for the viscosity adjusting tank. The liquid medium tank to be supplied, and a viscometer for measuring the viscosity of the photoreactive compound liquid in the viscosity adjusting tank, based on the measurement result of the viscometer and the temperature of the photoreactive compound liquid in the viscosity adjusting tank. A control unit that calculates the resin concentration of the photoreactive compound liquid, and determines the amount of a medium to be supplied to the photoreactive compound liquid based on a difference between the calculated resin concentration and a preset resin concentration; There is disclosed a photoreactive compound processing apparatus comprising a filter for removing foreign matter of the adjusted photoreactive compound.

  Further, Patent Document 2 discloses a regeneration container for containing and regenerating a photoreactive compound collected from a photoreactive compound film forming apparatus, and evaporating a medium component from the photoreactive compound in the reconstitution container. And a control device for controlling the operation of the medium liquid removing device, and the control device makes the viscosity of the photoreactive compound a target viscosity that can be effectively used. Heretofore, there has been disclosed a light-reactive composition adjusting system that operates a medium-removing device to remove a medium component from the light-reactive composition.

  In Patent Document 3, an excess of the photoreactive compound solution obtained from the film forming step is collected, and the solid content thereof is adjusted so as to be suitable for use as a film forming composition. Thereafter, particles and contaminants are removed from the solution. Next, there is disclosed a technique which is effectively used for forming a film of the photoreactive composition on a support.

  However, the method of adjusting the viscosity or the concentration of the solid content of the photoreactive composition thus collected often cannot be effectively used.

Thus, regardless of the type of the light-reactive composition, the regenerated light-reactive composition collected after the film is once formed on the core material can be used again for the production of the color-splitting light-transmitting structure. This is because the property becomes higher.

  According to the present invention, the alcoholic free radicals contained in the high molecular weight polymer are within the above range, so that when the photoreactive type composition absorbs moisture, it is contained in the photoreactive type composition.

Thereby, for example, after forming a film on the transparent core material by a liquid dropping type stretching device or the like, the above-mentioned photoreactive composition, the collected reproduction light reaction type composition for a color division light transmitting structure (hereinafter referred to as reproduction light). (May be abbreviated as a reactive composition).

  The present invention uses a light-reactive composition or a regenerated light-reactive composition, which can be used effectively in the production of a color-splitting light-transmitting structure, or a light-reactive or regenerated-light-reactive composition. The present invention relates to a color division light transmitting structure and a method of manufacturing the color division light transmission structure. Hereinafter, each will be described in detail.

A. First, the photoreactive composition of the present invention will be described. The photoreactive composition of the present invention is a photoreactive composition for a color-splitting light-transmitting structure containing at least a polymer having an alcoholic free radical, a monomer and an initiator. The alcoholic free radical contained in the high molecular polymer in the solid content of the photoreactive composition for a light transmitting structure is in the range of 0.1 mmol / g to 2.5 mmol / g. Things.

  The photoreactive composition of the present invention is used for a color division light transmitting structure constituting layer constituting a color division light transmitting structure. Here, the color-dividing light-transmitting structure constituting layer constituting the color-dividing light-transmitting structure referred to in the present invention is, for example, a colored layer, a polymer plastic light-blocking film, a transparent layer, and a photoreaction for forming a spacing-maintaining protrusion. It refers to a mold compound or the like.

  The color-dividing light-transmitting structure constituting layer constituting such a color-dividing light-transmitting structure is uniformly dropped by centrifugal force by rotating the core material after dropping an appropriate amount of the photoreactive composition on the core material. It is formed by a liquid dropping type film forming method for forming a transparent film. At this time, the excess photoreactive compound is repelled out of the core material by centrifugal force and collected. Such a photoreactive composition becomes fine droplets when it is repelled by centrifugal force, so it is easy to absorb moisture in the air, and there is a problem in the floating properties of the collected photoreactive composition. As such, they have been disposed of as industrial waste. As a result, there are problems such as low material efficiency, increased cost, and environmental pollution by waste.

  The cause of problems such as the floating properties of the collected photoreactive compound is, for example, the absorption of water molecules by bonding with the alcoholic free radicals of the polymer in the photoreactive compound by hydrogen bonding or the like. However, by bonding a plurality of high-molecular polymers, and also by this hydrogen bond, in the case of the colored particulate floating method, the colored particulates are suspended by the high-molecular polymer located around, The distance between the colored particles is short due to the polymer chains of the surrounding polymer shrinking in the suspended particles due to the action of the water molecules or being bonded to each other between the adjacent suspended particles. It is presumed that the colored particulate matter is bonded.

  According to the present invention, when the alcoholic free radicals contained in the high molecular weight polymer are within the predetermined range, the color-dividing light-transmitting structure forming layer is formed by the above-described liquid dropping film formation method or the like. In addition, it is possible to prevent the influence of moisture absorption of the light-reactive composition discharged to the outside of the core material, and it is possible to effectively use the collected light-reaction composition.

  In the present invention, the alcoholic free radicals contained in the high-molecular weight polymer are contained in the solid matter in the photoreactive composition within a range of 0.1 mmol / g to 2.5 mmol / g, particularly 0.1 mmol / g. / G to 0.7 mmol / g, particularly preferably 0.1 mmol / g to 0.5 mmol / g. Thereby, for example, at the time of forming the color-splitting light-transmitting structure constituting layer by the liquid dropping type film forming method, even if the light-reactive compound that has been repelled to the outside of the core material of the color-splitting light-transmitting structure is collected, even if it is collected, This is because the binding of granular materials, high molecular weight polymers, and the like can be prevented, and the compound can be used as a reproduction light reaction type compound.

The second aspect of the color-splitting light-transmitting structure of the present invention is characterized in that it has a color-splitting light-transmitting structure constituting layer in which the alcoholic free radicals are within a predetermined range.

  According to the present invention, since the amount of the alcoholic free radical in the color-separating light-transmitting structure constituting layer is within a predetermined range, as described above, the alcoholic free radical and the hydrogen bond between the water molecule are formed. It has a color-splitting light-transmitting structure component layer that has no floating polymer compound in the photoreactive composition that forms the color-splitting light-transmitting structure component layer, has good floating properties, and has a smooth surface. It becomes possible to make it a color division light transmission structure.

  It is preferable that the amount of the alcoholic free radical in the color-dividing light-transmitting structure constituting layer is in the range of 0.04 mmol / g to 1.8 mmol / g. In this case, the amount of the alcoholic free radical is a value calculated from the composition by a theoretical value.

  The color-separating light-transmitting structure of this aspect is not particularly limited as long as it has at least a core material and a colored layer formed in a fixed pattern on the core material. In addition, a black matrix, a transparent layer, and the like may be laminated, and the material, forming method, and the like are the same as those in the above-described first embodiment, and a description thereof will not be repeated.

D. Next, a method for manufacturing the color-splitting light-transmitting structure of the present invention will be described. The method for producing a color-splitting light-transmitting structure of the present invention is characterized in that, in a solid content of a photoreactive compound containing at least a polymer, a monomer and an initiator, the alcoholic content contained in the polymer is included.

  According to the present invention, as described above, by selecting a high molecular weight polymer having a low content of alcoholic free radicals, the binding of the high molecular weight polymer, such as when the photoreactive composition absorbs moisture, is prevented. This makes it possible to use the photoreactive composition collected once after the film is formed on the core material in the production of a color-splitting light-transmitting structure, and to reduce the cost of the color-splitting light at a low cost. It becomes possible to manufacture a transmission structure. Hereinafter, each step of the present invention will be described.

(1) Step of Preparing Light-Responsive Compound for Color-Division Light-Transmitting Structure First, the step of preparing a light-reactive composition in the method for producing a color-division light-transmitting structure of the present invention is described. The step of preparing a light-reactive composition in the method for producing a color-splitting light-transmitting structure of the present invention includes the step of preparing the light-reactive composition containing at least a polymer, a monomer, and an initiator in the solid content. The high molecular weight polymer is selected such that the content of the alcoholic free radicals contained in the molecular weight polymer is within a predetermined range, and the selected high molecular weight polymer, the above monomer, and the above initiator To prepare a photoreactive composition.

  This step has a great feature in that the polymer is selected such that the content of the alcoholic free radical contained in the polymer is within a predetermined range. As a specific selection criterion, when the photoreactive type composition is used as a regenerated photoreactive type composition, the content of the alcoholic free radical that does not cause a problem due to the contained water is a predetermined value. And a high-molecular polymer having a content of not more than this is selected. The relationship between the content of the hydroxyl group and the presence or absence of the moisture is determined in advance by conducting an experiment according to the system of the photoreactive composition. In the present invention, the predetermined value is determined in accordance with the value of the experiment performed in advance in this way, and from the high molecular polymers of the type adapted to the system based on this value, the high molecular polymer to be used is determined. It is unique in that it is selected and used.

  In the present invention, the alcoholic free radicals contained in the high molecular polymer in the solid content of the photoreactive composition are in the range of 0.1 mmol / g to 2.5 mmol / g, especially 0.1 mmol / g. It is preferable to select a high molecular weight polymer in the range of 0.7 to 0.7 mmol / g, particularly in the range of 0.1 to 0.5 mmol / g. By selecting a high molecular weight polymer containing a hydroxyl group within this range, in a variety of photoreactive formulations, when this is used as a regenerative photoreactive formulation, a problem due to moisture occurs. This is because the possibility can be extremely reduced.

  Calculations for selecting photoreactive formulations where the alcoholic free radicals are within the above range are made from theoretical values from composition.

  In addition, the photoreactive composition prepared in this step contains the high molecular weight polymer selected by the above-described method, and if it further contains a monomer and an initiator, other compositions etc. Is not particularly limited, and is determined according to the type of the color division light transmitting structure constituting layer in which the photoreactive composition is used. For example, when the photoreactive composition selected in this step is used for a colored layer, it may contain a monomer, a colored particulate material, an initiator, and the like, in addition to the above-described polymer. it can.

  The method for preparing the photoreactive compound in the present invention is prepared by a method generally used conventionally, and specifically, comprises the above-described polymer, monomer and initiator. A method is used in which a photoreactive composition is prepared by mixing and dissolving, and if necessary, a colored particulate material or the like is added thereto.

(2) Step of Producing a Color-Division Light-Transmitting Structure Next, a step of producing a color-division light-transmitting structure in the method of producing a color-division light-transmitting structure of the present invention will be described. The step of producing a color-splitting light-transmitting structure in the present invention is a step of producing a color-splitting light-transmitting structure using the light-reactive composition prepared in the above-described light-reactive composition preparation step.

This is a photoreactive composition comprising a mold composition containing light-shielding particulates.

  The photoreactive composition 2 for black matrix is subjected to pattern exposure through a mask 3 formed along a certain pattern of the black matrix. The black matrix photoreactive composition 2 thus pattern-exposed is developed and washed to obtain a black matrix 4 formed in a fixed pattern as shown in FIG. 1 (b).

  Next, as shown in FIG. 1C, a photoreactive compound 5 for a colored layer is formed on the core material 1 having the black matrix 4 formed in a fixed pattern. The photoreactive composition 5 for a colored layer is a photoreactive composition using the high molecular weight polymer having an alcoholic free radical content within a predetermined range selected in the photoreactive composition preparation step described above. This is a light-reactive composition in which colored particles corresponding to the color of a colored layer to be formed are suspended. The photoreactive composition 5 for a colored layer is subjected to pattern exposure through a mask 3 'formed along a predetermined pattern of the colored layer. By developing and washing the colored layer photoreactive compound 5 thus pattern-exposed, a colored layer 5 'formed in a fixed pattern is obtained as shown in FIG. 1 (d). .

  When a color-divided light-transmitting structure of a plurality of colors (for example, three colors) is formed, the same process is repeated three times to form a colored layer 5 ′ of three colors as shown in FIG. Can be formed.

  Next, as shown in FIG. 1 (f), a photo-reactive composition for a transparent layer is formed on the colored layer 5 'formed in a predetermined pattern to form a transparent layer 6. In the present invention, this transparent layer 6 can also be formed using the above-mentioned photoreactive compound.

  Further, as shown in FIG. 1 (g), a film of the photoreactive composition for spacing maintaining protrusions 7 is formed on the transparent layer 6, and the photoreactive composition for spacing maintaining projections 7 is formed on the transparent layer 6. Pattern exposure is performed through a mask 3 ″ formed along a predetermined pattern of the holding projections. By developing and washing the light-reactive composition for spacing maintaining projections 7 thus pattern-exposed, the light-reactive composition for spacing maintaining projections 7 is formed in a fixed pattern. As shown in FIG. 1 (h), it is possible to obtain the space keeping projection 7 '.

  As described above, in the method for producing a color-splitting light-transmitting structure of the present invention, the above-described light-reactive composition is provided with a colored granular material or a light-shielding granular material as necessary for each of the color-splitting light-transmitting structure constituent layers. A color-separated light-transmitting structure can be manufactured using a light-reactive composition in which a substance or the like is floating. Therefore, when forming these color-separating light-transmitting structure constituent layers, a conventionally discarded light-reactive composition can be used as a regenerated-light-reactive composition. Can be reduced. Therefore, it is effective in improving the material efficiency, and the cost can be reduced. Also, in terms of the environment, since the amount of waste can be reduced, the burden on the environment can be reduced. Furthermore, since the amount of alcoholic free radicals in the photoreactive composition is within a predetermined range as described above, for example, even when moisture is absorbed, the photoreactive composition may be affected by water molecules. Low lightness and low deterioration of floating property, etc., good lightness and darkness due to good floating property, and easy to remove uncured photoreactive compound when forming a certain pattern Therefore, it is possible to form a component layer having a very clear and constant pattern.
