[Prior Art] 随 随 = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = (The so-called shortcomings) The report is small, and since the display is formed by the g-points that are confirmed by g, the accuracy of the inspection for improving the defects becomes daily. For example, the inspection of the defects of the light plate is generally performed by visual inspection of the orthogonal polarization method. South...Yu Zhengfu polarized ΐ 'When the two polarizing plates are overlapped with each other so that their two m-axis is in the state of light, * if there is a defect, it will appear as a bright spot, thereby enabling Perform visual inspection of defects. The light plate is made of a material such as a liquid crystal cell by an adhesive, and is used as a target for the production of a miscellaneous film, and the adhesive plate attached with Na# is usually attached to the polarizing plate _·τ ^. The hybrid yarn is usually visually inspected by a crossed polarizing method in the case where the peeling sheet is used. Therefore, the second test is a hindrance to the inspection of the JL cross-polarization method. It is known that the peeling sheet-=material makes the ship tilt toward the main enemy (g(10), and (4) (for example, refer to Patent Document 1). The release agent layer of the release sheet used in the use of a polarizing plate is formed by coating a resin composition on one surface of the substrate, followed by heat curing. In the upper = stone resin composition, for example, an organic reference having an alkenyl group is used. Patent Document 2). [Patent Document 1] JP-A-2002-172694 [Patent Document 2] Japanese Patent Laid-Open Publication No. Hei. No. Hei. In order to form the release agent layer, in order to make the release agent layer more excellent in hardenability, the temperature of the release sheet substrate is often caused by such high temperature heating, and the distribution angle of the alignment angle (maximum and minimum) The difference in value) produces a change. Therefore, even if the distribution of the secret (4) is smaller than that of Lai Lai, the problem is that the crystallization of the distribution _ _ 之 变 变 会 会 , 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的 的The touch of the inspection does not sufficiently improve the inspection accuracy. On the other hand, in order to suppress the change in the alignment angle of the release sheet substrate, when the heating temperature at the time of curing is lowered, there is a problem that the release agent layer is not sufficiently cured or the release property of the release agent layer is lowered. In view of these problems, the present invention has an object of providing a high-accuracy inspection in the inspection of the orthogonal polarizing method when attached to a polarizing plate, and the peeling performance is good, and the peeling sheet is used. _ There are ^~ plates, and no substrate double-sided adhesive sheets.锔 ❹ ❹ 剥离 ' 是 是 剥离 剥离 剥离 剥离 剥离 剥离 剥离 剥离 剥离 剥离 剥离 剥离 剥离 剥离 剥离 剥离 剥离 剥离 剥离 剥离 剥离 剥离 剥离 剥离 剥离 剥离 剥离 剥离 剥离 剥离 剥离 剥离 剥离 剥离 剥离 剥离 剥离 剥离 剥离 剥离 剥离When the composition is formed into a hard-like film, the reaction-type product of the reaction product includes an ethylene group having a carbon number of 6 to 1 Å in the molecular towel, and an MQ resin having an alkenyl group in the molecular towel. In the sample, the distribution of the inclination (alignment angle) of the alignment main axis of the release sheet substrate of the straight line set in any of the four directions was five. the following. In the longitudinal direction when the linear axis is set to extend the polyester film, the MQ resin has a unit of si〇2, a unit of (CH3)3, and a unit of 200946333=ί=ζ(σί3). , z wire material _ ^ invented with a _ sheet of polarizing plate, according to polarizing plate, sticky

Set succinctly, the peeling piece is formed in the lion piece A = two Γ ΐϊϊΐΐ 且 and the stripping agent layer is in a peelable manner and pretends to be squatting; the dough piece substrate is a single thief double vinegar Membrane; stripping _ layer is _ plus reaction tree tester to harden the film formed by the 'additional reaction type bismuth resin composition contains the organic poly-wei in the winter ❹ _ number of 6~1G, and in the molecule In the case where the sample is sampled from the release sheet, and the sample is sampled from the release sheet, and the uppermost axis is set in the direction of the extension width of the film, the release sheet is used. The maximum value of the alignment angle (alignment angle) of the substrate is 5. the following. The double-sided separator and the heavy-peeling sheet of the present invention are characterized in that the release sheet is formed by separating (4) the surface of the release sheet substrate. And the ship is detachable from the aforementioned adhesive layer; the adhesive with the light release sheet = force ratio is lower than the adhesive force of the heavy release sheet, and the substrate is uniaxial or biaxially extended. Poly Lai; the exfoliation is an additional reaction ^ ^ grease _ material series hard-drinking coffee formation, attached to the deficiencies of the fat group, the substance contains an organic group with a carbon number of 6 ~ 1G alkenyl in the molecule Shi Xi H and MQ resin having a thin base in the molecule; and in the material sampled from the peeling sheet, 'the inclination of the alignment main axis of the off-chip substrate with respect to the linear axis set in any direction (alignment angle) The distribution range is 5. the following. Preferably, when the linear axis is set to the length direction or the width direction when the polyester film is stretched, the maximum value of the tilt (alignment angle) of the alignment main axis of the substrate is 5. the following. Preferably, the above adhesive layer is 23. (The storage elastic modulus (G,) is formed by an adhesive of 200946333 〇.3 MPa or more. In the present invention, 'the hardening is performed at a relatively low temperature by using a predetermined enamel resin composition in the release agent. Since the release agent layer can further improve the hardenability, the release property of the release sheet can be further improved. Further, by curing the release agent layer at a low temperature, it can be maintained even after the release agent layer is formed. Since the distribution range of the small alignment angle of the release sheet substrate is high, it is possible to perform inspection with high precision in the inspection by the orthogonal polarization method.

The present invention will be described in more detail below using embodiments. The release sheet according to the embodiment of the present invention has a release layer layer formed on one of the release sheet base materials, and can be used, for example, in a polarizing plate. The release sheet substrate as the release sheet is a uniaxially or biaxially stretched stretched polyester film having a low distribution range of the alignment (alignment angle) of the alignment main shaft, but preferably an extension using a biaxial extension. Polyester film. In the sample sampled from the release sheet which was hardened from the release sheet substrate to the release agent layer, the distribution angle of the release sheet substrate opposite to the linear axis which was not in any direction was 5 . Below, the better is 4. the following. As the polyester film, a uniaxially stretched film in which a strip-shaped film extends in the width direction (or the longitudinal direction) or a biaxially stretched film in which a strip-shaped film extends in the width direction and the longitudinal direction is used. Meanwhile, in the sample sampled as described above, preferably, when the linear axis is set to the longitudinal direction or the width direction of the film when the film is extended, the inclination (alignment angle) of the alignment main axis of the release sheet substrate is the largest. The value is 5. the following. As the polyester film, a pET film: a PEN film or the like is exemplified, but it is particularly suitable to use a biaxially stretched pET film. The reason is because transparency, heat resistance, planarity, and strength are preferred. The release agent layer of the present embodiment is obtained by applying a reaction-reactive resin composition diluted with an appropriate organic solvent to a release sheet substrate, and then adding or heating by heating and ultraviolet light. The reaction of the fiscal tree is red, and the hardened film is formed. The additional reaction type bismuth resin composition is composed of organic sand oxide having a gangue number of 6 to 1 G in the molecule, and the MQ resin, bridging agent, and catalyst added at 200946333 are also available. The reaction inhibitor 1 is a lifter or the like. Further, in the case of hardening and peeling, when light irradiation such as ultraviolet rays is applied to the heating in the force μ, =, the light-initiating agent may be added to the product. When the stripping agent layer is hardened, the heating temperature is (4) the heating temperature at the time of hardening, and it is preferable to prepare the organic poly-wei which has the carbon number of 6 to ω, and the use of 6~ has at least two bases. . As the number of carbon is Φ? The more hexanyl. As a specific example of such an organic polyfluorene, it is indicated by the following general formula (I).

In the present embodiment, by using an organic polyfluorene having an alkenyl group having a carbon number of 6 to 10 on the main component of the release agent, the heating temperature at the time of heat curing of the release agent layer is set to a relatively low temperature. (For example, 95 to 1 〇5. 〇, it is also possible to form a release agent layer having excellent hardenability. Thus, the release agent layer having a good hardenability has excellent peeling force in stability over time, and further, the release sheet is removed from When the adhesive layer is peeled off, it is not necessary to completely lower the adhesive force of the adhesive layer, and a good residual adhesive force can be obtained. Further, by setting the heating temperature at the time of heat hardening to a low temperature, since the heat of the peeling sheet substrate can be suppressed Since the original orientation of the substrate can be maintained by shrinking, the distribution angle of the alignment angle after the formation of the pressure-sensitive adhesive layer of the release sheet substrate can be set to 5 or less. The embodiment of the present invention is provided with a peeling. The polarizing plate of the sheet is formed by laminating the polarizing plate (polarizing film), the adhesive layer and the peeling sheet in the order of the peeling 8 200946333 2, and the length of the polarizing axis of the off-line layer is width The direction is the peeling off from the polarizing plate: 丨田• is layered. The polarizing plate with the peeling sheet is on the peeling sheet.

The shape of the transition 23 is in the range of __ sex rate (7), particularly preferably 〇35 to 12 MPa, and most preferably 〇5 to 5 MPa. Adhesives, such as the Japanese special open 2〇〇7_197659 & dew-like is in the inclusion of a silk-containing monomer to monomer G = from the quality of the hundred-knife ratio below the C-type co-existing body, and active energy line According to the post-hardening type compound, the hybrid energy such as the riding line, constitutes an adhesive of 0.3 MPa or more at 23 tT after the age of the beach. In addition, regarding the above-mentioned C-type co-extension, ^ , for example, (9) (10) _ recombination, or does not contain a silk body "complex. In addition, for example, as an adhesive, such as Japan 2 〇〇 7 _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ ), the monomer having a carboxyl group has a monomer composition ratio of 1% by weight or less, a propylene-based superposed body f component having a weight average molecular weight of 1,000,000 or more, and an adhesive material of an active energy ray-curable compound; The energy line is composed of the adhesive agent having a storage elastic modulus (G,) at 3 °〇 after the activation of the active energy ray is 〇.3 MPa or more, and the above (A') component and the output) 9 200946333 The mass ratio is 100:1 to 100:50, and as a monomer composition, a monomer having 0.1% by mass or more of a decyloxy group and containing

A monomer having more than 0.1% by mass of a carboxyl group. These adhesives are formed by applying an adhesive material to a release agent layer such as a release sheet and drying it, and then curing it by irradiation with an active energy ray to form an adhesive layer. The adhesive layer used for the polarizing plate is often subjected to post-peeling after being attached to the polarizing plate in order to correct the deviation of the bonding. Since the above-mentioned adhesive can maintain a relatively low adhesive force with stability for a long period of time, it can be easily peeled off from the polarizing plate even after being bonded to the polarizing plate until a long time elapses. Further, the above-mentioned adhesive has a high cohesive force and hinders the improvement of the peeling force of the release sheet. However, as in the present embodiment, an organic polyfluorene containing an alkenyl group having a carbon number of 6 to 10 and an alkene are used. The release agent composition of the base MQ resin can sufficiently increase the peeling force of the release sheet. Further, in the present specification, the average molecular weight of 〜1曰1灵1 is a value in terms of polystyrene measured by the Gel Permeatum Chr_t〇gmPhy (GPC) method. In addition, the storage elastic modulus (G,) under the pit is thick and measured by the following conditions using the twisting shear method.

In the application of the polarizing plate, for example, after the protective sheet is peeled off, it is used by being exposed to a polarizing plate or the like. At this time, the extending direction or the width direction of the polarizing plate is such that the length of the polarizing plate of the polarizing plate can be sharpened and adhered to the polarizing plate with the attached surface.

For example, by setting the peeling force difference between the two sheets to a predetermined value or more, it is possible to prevent peeling failure which occurs when the protective sheet is peeled off from the adhesive layer. Further, the peeling force of the release sheet and the protective sheet as described herein is measured based on JIS_Z0237 as described in detail below. g In each embodiment of the present invention, the resin composition and the adhesive material are, for example, a GRAVIURE COAT method, a BAR COAT method, a SPARY COAT method, a SPIN COAT method, a KNIFE COAT method, a ROLL COAT method, a DYE COAT method, or the like.

Changed to be good.

Further, in the examples, since the organic polyfluorene having the ruthenium and the Mq resin having the alkenyl group on the release agent composition are used, the residual adhesion rate and the peeling force can be obtained even if the curing temperature is low to a low temperature. Any change in time is excellent. On the other hand, in the comparative example using the organopolyoxyl which has an ethyl group in the composition of the stripper, when the hardening temperature is lowered to a low temperature, since the stripper composition is not sufficiently hardened, the residue remains. Then, the rate is lowered, and the change in the peeling force with time is also large, and the release sheet having good peeling properties cannot be provided. Further, even in Comparative Example 2 in which Example 1 and the release agent composition were used in the same manner, the change in peeling force with time was increased by increasing the curing temperature, and it was not possible to provide a release sheet having good peeling properties.
