If the content of the above antistatic agent (F) is too small 'There is a tendency that the blending effect is not obtained, and if it is too large, there is a possibility that the durability is deteriorated or the antistatic agent bleeds out. In the present invention, the adhesive can be formed without damaging the effects of the present invention. The resin composition [I] of the material is further formulated with the following materials: other acrylic acid adhesives, other adhesives, amino phthalic acid ethyl ester resin, rosin, rosin vinegar, hydrogenated rosin Ester, phenol resin, aromatic modified terpene resin, aliphatic 097143007 46 200932856 petroleum resin, alicyclic petroleum resin, styrene resin, diterpene benzene resin, polyglycol and other tackifiers, colorants, a well-known additive such as a filler, an anti-curing agent, an ultraviolet absorber, a functional dye, or a compound which causes coloration or discoloration by ultraviolet rays or radiation. Further, in addition to the above additives, a small amount may be contained. In the present invention, an adhesive for an optical member obtained by crosslinking the resin composition [j ] can be obtained by borrowing the resin composition [J ]. By providing the adhesive on the optical member (optical laminate), an optical member with an adhesive layer can be obtained. Among the optical members of the adhesive layer, it is preferably opposite to the optical member of the adhesive layer. The release sheet is further provided on the surface.

The method for producing the resin composition [I] on the release sheet is preferably (2) in terms of the possibility of deterioration of the material. Further, in practical applications, the release sheet is used. It is better to use it for peeling off - the release sheet is a release sheet of the lanthanoid series. In the case where the resin composition [I] is irradiated by an active energy ray and heated to the sacred species for parenting, It is produced by the following method: [1] coating a resin composition [Ϊ] on an optical member, and drying the bonded release sheet, and treating it by at least one of 097143007 47 200932856 active energy ray irradiation and heating; (2) The resin composition is applied on the mold [, and the optical member is bonded after drying, and is treated by at least one of activity = line irradiation and heating; [3] on the optical member = cloth resin composition [I ]' and dried And then processed by at least one of active energy ray irradiation and heating. Bonded release sheet; [4] the resin composition is applied on a release sheet [1], and dried, and further processed by the at least one active energy ray irradiation and heating purposes, and then bonded to the optical member. Among these, the method of (2) is preferred from the viewpoint of the substrate, operability, and stable production, and only the active energy ray is irradiated. In the case of the above coating, it is preferably diluted with a solvent and applied as a dilution/agronomy, preferably from 1 to 5 % by weight, particularly preferably from 丨丨 to 扛 by weight.

If the gel fraction is too low, there is a tendency that the durability is insufficient or the light leakage phenomenon is deteriorated due to insufficient cohesive force. In addition, the upper limit of the gel fraction is usually 100%. 〇097143007 48 200932856 In addition, when the gel fraction of the optical member adhesive is adjusted to the above range, for example, it can be achieved by adjusting the active energy. The irradiation amount or the irradiation intensity of the line 'adjusts the type and amount of the unsaturated group-containing compound, adjusts the type of the polymerization initiator and the ratio thereof, adjusts the amount of the polymerization initiator, and adjusts the type and amount of the crosslinking agent. . Further, since the gelation rate changes due to the interaction between the irradiation amount of the active energy ray, the irradiation intensity, the composition ratio of the polymerization initiator, and the blending amount, it is necessary to obtain a balance therebetween. Further, the above gel fraction is a standard of the degree of crosslinking, and can be calculated by the following method. D. That is, an adhesive sheet obtained by the following method using a 200 mesh S u S wire mesh (the separator is not provided) is placed in toluene at 23. The underarm was dipped for 24 hours. The insoluble adhesive component = weight percentage remaining in the wire mesh was taken as the gel fraction. The weight of the substrate is previously subtracted. Further, the thickness of the adhesive layer in the optical member to which the adhesive layer is obtained is not particularly limited 'better 5 to 3 Å, particularly preferably 1 to 5 Å, more preferably 12 to 30 Vm. If the thickness of the adhesive layer is too small, the adhesive property tends to be unstable, and if it is too thick, the thickness of the optical member tends to increase excessively. ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, The substrate is then used for, for example, a liquid crystal display panel. 0 097 143 007 49 200932856 The initial adhesion of the adhesive layer of the present invention is appropriately determined depending on the material of the adherend or the like. For example, in the case of adhering to a non-tested glass plate, it is preferred to have an adhesive force of 0.01 N/25 mm to 50 N/25 mm. Further, even in the case of permanent completion, if static electricity is generated during secondary processing (re-adhesion), there is also adhesion of dust, etc., and therefore antistatic property is required. The above initial adhesion is calculated in the following manner. The optical member to which the adhesive layer was prepared was cut into a width of 25 mm, the release film was peeled off, and the adhesive layer side was pressed against an alkali-free glass plate (Corning 1737 manufactured by Corning Co., Ltd.). And the optical member is bonded to the glass plate. Thereafter, autoclave treatment (50 ° C, 0.5 MPa, 20 minutes) was carried out, and after 24 hours, a peeling test was performed at 180 ° C. The optical member of the present invention is not particularly limited, and examples thereof include an optical film suitable for an image display device such as a liquid crystal display device, an organic EL display device, or a PDP, such as a polarizing plate, a phase difference plate, an elliptically polarizing plate, and optical compensation.

[Initial adhesion] © The obtained adhesive sheet After the material was cut into 25 mm x 100 faces, the adhesive sheet was crimped to the stainless steel plate as the adherend by using a 2 kg rubber roller twice at 23 ° C and a relative humidity of 50%. A test piece was prepared on the SUS304ba board. The test piece was allowed to stand in this environment for 30 minutes, and then subjected to a peeling test of 180 degrees at a peeling speed of 0.3 in/min, and the initial adhesion (N/25 mm) was measured. [High Speed Peelability] ® After the obtained adhesive sheet was cut into 25 colors x 100 mm, it was at 23.

Further, it is also known that the high-speed peeling detachment value is not so large as compared with the low-speed peeling value of the adhesive sheets, and the stain resistance is also excellent, so that it is excellent as a surface protective adhesive sheet. Since the anti-static agent was not added to the sheet of Example 18, the antistatic property was slightly inferior to those of Examples 14, 15, 16, and 17, but it was excellent in transparency as compared with Comparative Example 5 having turbidity. . It is understood that the adhesive sheets of Examples 19 and 20 are more excellent in antistatic properties and coating film transparency than Comparative Example 6. These properties are generally considered to impart high antistatic properties and transparency of the coating film due to the large use of the hydroxyl group-containing monomer in the acrylic resin. In view of the above physical properties, it is understood that the adhesive sheets of Examples 14 to 097143007 76 200932856 20 are excellent as an adhesive sheet for surface protection. The present invention has been described in detail above with reference to the specific embodiments thereof, but it is understood by those skilled in the art that various changes and modifications may be made without departing from the spirit of the invention. The present application is based on a Japanese patent application filed on Nov. 7, 2007 (Japanese Patent Application No. 2007-289605), and Japanese Patent Application No. 2007-331346 filed on Dec. 25, 2007, It is cited here as a reference. (Industrial Applicability) The spotting agent of the present invention is not easy to carry the static electricity generated in each step, and is excellent in the adhesion between the optical laminate and the glass substrate under conditions of temperature and high humidity. Since foaming or peeling does not occur between the pressure-sensitive adhesive layer and the glass substrate, and light leakage due to shrinkage of the optical film can be suppressed, a liquid crystal display panel excellent in durability can be obtained, which is very useful. 097 097143007 77
