The content of the surfactant in the composition for forming a hard coat layer is preferably from 0.1 to 2.5% by weight, more preferably from 5% to 0.02% by weight. In the present invention, the relationship between the arithmetic mean roughness (Rah) and the Ra of the interface on the far side of the base film is preferably Rah &lt; Ra. Further, it is preferably 0.1 p or less, more preferably 0.07/am or less, and 'larger than the above value', the unevenness after forming the low refractive index layer described later becomes large, and the hard coat layer 36 201127621 and the base film layer are formed. When the integrated body is used as an antireflection film on a display device, there is a tendency to reduce the sharpness of the display device. The method of setting the hard coat layer from the interface on the far side of the base film to the above range, and using the solvent having a small evaporation rate as described above, a composition for forming a hard coat layer The method of reducing the surface tension. The method of reducing the surface tension of the composition for forming a hard coat layer may be a method of adding the smoothing agent to the composition for forming a hard coat layer or a method of reducing the solid content of the composition for forming a hard layer. On the surface of the hard coat layer, a surface treatment can be applied. The means for the surface treatment may be the same as the surface treatment method of the above-mentioned base film. The film of the base film and the hard coat layer formed by forming a hard coat layer on the base film is directly or after the base film is peeled off according to f, (4) is a film for the hard coat layer of the present invention. . Further, in the case of Dan, the base film may be formed into the outermost layer, and after the first film and the second film are adhered, the base film may be peeled off. A laminate having a hard coat layer and a base film is directly used as the first or the first aspect of the present invention. Amine # # 2臊 When used for pasting, the total thickness can be 30#m~500#m. Horse (Manufacturing Method) The optical enthalpy of the present invention can be favorably produced by the production method of the present invention, and the method comprises: (1) a surface of the first film facing the object and the second film Then, the surface of the object or both of them are coated with the post-hardening adhesive to form a coating film of the post-hardening adhesive; 37 201127621 (π) drying the coating film to obtain an uncured layer of the post-hardening adhesive; The second film and the second film are adhered to each other via the uncured layer via the uncured layer; (IV) the uncured layer is irradiated with an active energy ray to form a cured adhesive layer. The first film and the second film used in the above production method are preferably supplied as a film of ^ ^ Ύ. The long film ' means a length having a length of at least 5 (four) or more in the width direction of the film, preferably 10 times or more, and specifically 4 means a length which is stored in a roll form or stored. In the step (1), if necessary, a pretreatment such as corona treatment may be applied to the first film and the second film to improve the adhesion of the post-hardening. In the step (I), the first film is carried out next to the object. The formation of the coating film of the post-hardening adhesive, usually, the coating method of the surface of the second film or the surface of the object to be coated of the second film can be used for the coating of the continuous film, and the curtain coating There is no particular limitation on the law, the narrow (four) shirt dragon (four) method, the spraying method, and the like. Preferably: can be combined with the desired thickness of the hardened adhesive layer: / 〇 · 5 ~ 100 (four) is better, with 1 ~ 5 - better. By making the film have a thickness of 100 &quot; m or less, the hardening rate of the unhardened layer can be reduced, and sufficient hardening can be achieved. The intention is that in step (11), the drying will be carried out by, for example, 50 to 150 tons, i 38 201127621 minutes. By this drying, an uncured layer having a thick film thickness can be obtained. In the step (1) 1) 'adhesion' can be carried out by means of a laminating means. In particular, it is preferable to continuously laminate the long first and second films. Specifically, it is preferable to continuously pressurize the first film, the uncured layer having the thickness X, and the second film with a pressure roller. Here, the continuous pressurization by the pressure roller is performed by pressing the surface of the layered object of the object to be applied in the direction in which the axial direction of the roller is parallel, and continuously moving in the direction orthogonal thereto to achieve pressurization. Referring to Fig. 1, a step 郦r τ τ τ, a step (111) is continuously pressurized by a pressure roller, and a sample diagram showing a pasting step of the manufacturing method of the present invention. In Fig. 1, the bank composed of the first film n 犋 11 and the uncured layer 12 is moved between the two cylindrical pressure rollers 21 and 22 in the direction of the arrow A1. By this, hey! The film is not hardened; and the second film is continuously added by the pressure rollers 21 and 22 to the second layer. And the laminated body composed of the second (10) is continuously supplied with 0 ' in the step (III), especially in the case of removing the bubble at the time of sticking (the phenomenon of forming bubbles between the film 1 and the second film). In the continuous layer, it is better to increase the clamping force between the pressure rollers, to lower the pressure processing speed, and to handle the vacuum pressure in the second (fourth) treatment. In order to increase the surface pressure, in general, the laminate including the adhesive layer is pressurized, and the overflow of the adhesive is generated on the upstream side of the pressure roller, which is not shown in the first film 11 and Between the second object, not ...; 2 overflow 12H. Such an overflow 'has an uneven thickness of the adhesive layer, 曰 significantly 39 201127621 to reduce the optical properties of the optical components of the product. As a method of reducing the overflow, it is considered to reduce the pinch pressure of the pressure roller. However, when the pinch pressure of the low-pressure wheel is reduced, the adhesion of the shell may be insufficient, resulting in a bite, which may impair the optical performance. In addition, the adhesion between the first and second films is also deteriorated. However, when the specific particles of the optical element used in the present invention are further modified to form a uncured layer which is dried at a specific thickness to continuously pressurize the layer, the overflow H can be remarkably reduced even if the clip is not lowered. The pressurization can achieve the pressurization of the uniform hook. In this way, the uniformity of the film thickness and the reduction of the bubble generation can be achieved, and as a result, an optical element excellent in optical performance and durability can be obtained. The material of the pressure rollers 21 and 22 which are shown in Fig. i can be a material having a rubber hardness of 60 to 100 degrees such as acrylonitrile butadiene rubber or ruthenium rubber, or a metal such as SUS or iron. A preferred combination 'for example,' is shown in Fig. 1. When the film thickness of the substrates 13A and 11 is 11M3A, a rubber roller is used for the pressure roller 21 that is in contact with 13A, and a metal roller is preferably used for the pressure roller 22 that is in contact with 11. Thereby, curling of the optical element due to lamination can be suppressed. The irradiation of the uncured layer by the active energy ray in the step (IV) may be carried out by either one of the first film and the second film, or by both sides as needed. For example, the second film system contains a layer of a cholesteric resin layer, so that the incident light is reflected - part of the film 'the other second film is transparent, for example, a film having a total light transmittance of 80% or more) At the time, the irradiation of the active energy ray can be performed favorably through the second film '. The ',' and the active energy lines of the shot can be applied to the energy lines of the post-hardening adhesive, such as ultraviolet rays, visible rays, and other electronic wires. It is preferred to use an ultraviolet curable type of adhesive agent to irradiate ultraviolet rays. The irradiation is carried out by attaching the long film which is adhered after the completion of the step (111) to the wide direction of the film by supplying the film continuously to the irradiation region. The light source for irradiating ultraviolet rays may, for example, be a low pressure mercury lamp, a medium pressure mercury lamp, a pressure mercury lamp, an ultra high pressure mercury lamp, a chemical lamp, a light-diffusing microwave excited mercury lamp, and a metal toothed lamp. The irradiation intensity at the time of irradiation with ultraviolet rays is not particularly limited, and the irradiation intensity in the wavelength region effective for activation of the polymerization initiator is preferably 50 to 5000 mW/cm 2 , more preferably 100 to 300.0 mW/CIn2, and further 3 Å. ~2〇〇〇mW/cm2 is better. When the irradiation intensity is less than 50 mW/cm2, the reaction time is too long and there is insufficient hardening and not L. When the irradiation intensity exceeds 5 〇〇〇mw/cm2, the radiant heat of the lamp, the heat of polymerization reaction, or the like may cause yellowing of the adhesive, or the hardening shrinkage of the subsequent layer may become large, and the adhesion may be lowered. The light irradiation time is appropriately selected according to the hardening condition, and is not particularly limited. The cumulative light amount expressed by the product of the irradiation intensity and the irradiation time is set to 10 5 , preferably 〇〇〇mj/cm 2 . The cumulative amount of light is preferably better than 〇〇mJ/cn]2, and the step-by-step is 500~2, 〇〇〇mj/cm2 is preferred. The steps (I) to (IV) can be carried out continuously or partially on the line as needed, whereby the production can be more efficiently performed. After the steps (I) to (IV) of the process, any additional processing can be performed to know the optical component of the final product. For example, when a film having a substrate and a bile layer is used as the first or second crucible, after the step (IV) is completed, the substrate is peeled off by σ, and the final mouth is formed. mouth. Further, when a film having a hard coat layer and a base film of 41 201127621 is used as the first step (IV) and then the base material (use) 1 or the second film is used as needed, the final product can be formed by completing the step. The meta-information of the undead is not particularly limited, and it is necessary to select the first film and the second film by the appropriate connection, and it is necessary to form various optical elements in a plurality of layers. For example, a selective reflection layer having a cholesteric resin layer can be used as the first film, and a second film can be used as the 波长 wavelength plate by using a transparent tree & amp amp ' ' ' ' The optical element is composed of a brightness enhancement film. Brightness The lifting film is attached to a liquid crystal display device and can be used between the backlight and the liquid crystal cell.
