Description of the Invention: Related Applications • This application claims Japanese Patent Application No. 2007-211538 filed on Jan. 14, 2007, and Japanese Patent Application No. No. 5, filed on Jan. 14, 2007. The priority of 2007-211539, the entire contents of which is incorporated herein by reference. TECHNICAL FIELD OF THE INVENTION The present invention relates to a binder composition and an optical element. 10 [Prior Art] Flat panel displays are usually laminated with various optical films bonded together by a layer of adhesive. Moreover, such optical films typically have a release film and/or a surface protective film to prevent scratching and/or contamination thereof. 15 Flat panel display panels are prone to electrostatic discharge at their surface. If a surface discharge occurs, the display side of the flat panel display panel can attract dust. • Electrostatic discharge can also affect the orientation of the liquid crystal molecules in the display circuit of the semiconductor substrate and/or the liquid crystal display panel in the flat display panel. As a result, the display may malfunction. :20 Therefore, flat display panels require antistatic properties. However, if each of the antistatic layer and the adhesive layer are separately formed, resulting in deterioration of productivity, an alternative method is required to form an antistatic layer. Furthermore, if the adhesive layer of the optical film contains an antistatic agent, the adhesive layer has antistatic properties and thus does not require an additional antistatic layer. 4 1378980 However, when a binder composition is applied to a substrate such as an optical sheet to form a binder layer, the binder layer occasionally inhibits the optical properties of the optical sheet and/or imparts an insufficient antistatic effect to the optical sheet. 5 SUMMARY OF THE INVENTION The present invention is directed to solving the above problems associated with the conventional art, and it is therefore an object of the present invention to provide a binder composition which can be used to form an adhesive layer having a favorable antistatic property without deteriorating coating. Optical properties of optical sheets with a layer of adhesive. Another object of the present invention is to provide an optical element comprising the above binder composition. To achieve the above object, the present invention employs the following technical structure. The binder composition of the present invention comprises: (A) a copolymer comprising (al) at least one or two or more (meth) acrylate having a halogen element 15 selected from the group consisting of a propyl acrylate of a halogen element and a methyl propyl acrylate having a halogen element, and (a2) at least one or two or more (meth) acrylates selected from the group consisting of acrylates and sulfhydryl groups Acrylate; and (B) an antistatic agent comprising an ionic compound. In the binder composition according to the present invention, the acrylic vinegar and/or the methyl 2-oxime acrylate may include H2C=C(Rl)COO(R2) (wherein R1 is ruthenium or CH3, and R2 is at least one selected from the group consisting of CH2CF3 , CH2(CF2)2H, CH2(CF2)4H, CH2CH2(CF2)6F, CH2CH22(CF2)8F, CH2CH2(CF2)i〇F, CH2CH2(CF2)12F, CH(CF3)2, CF(CF3)2 , CH2CH(0H)CH2C1, CH2C6Br6, CH2C6H3Br3 and 5 1378980 CH2C6H4Br2). The binder composition also preferably comprises a copolymer in crosslinked form. The optical element of the present invention comprises an optical sheet coated with one or both sides of the above binder composition. [Embodiment] Hereinafter, preferred embodiments of the present invention will be described in more detail. Adhesive Composition 10 The adhesive composition according to an exemplary embodiment of the present invention may comprise a copolymer (hereinafter referred to as "base polymer") which copolymerizes an acrylate having a halogen element and/or a The acrylate is prepared with other acrylates and/or mercapto acrylates; and an antistatic agent that substantially comprises an ionic compound. The base polymer contained in the composition is preferably crosslinked using a crosslinking agent. Since the antistatic agent is added to the base polymer, when the binder group is applied to a substrate such as an optical sheet to form a binder layer, the binder layer exhibits, for example, lxio8 to 1χ1013 (Ω/[Ι]), Surface resistance of good ground lxio8 to lxio11 (Ω/port). 20 Antistatic Agent The antistatic agent used in the binder composition according to the present invention may contain an ionic compound. The ionic compound may be selected from specific compounds which are compatible with the organic solvent commonly used in the preparation of the binder composition and which maintain the transparency of the binder composition if the ionic compound is added to the base polymer. Moreover, when the binder composition is applied to a substrate such as an optical sheet to form a binder layer, the ionic compound is selected from a specific compound which imparts a specific surface resistance of not more than 1 χ 1 〇 12 (Ω/d) to the binder layer. The ionic compound may include at least one member selected from the group consisting of an imidazolium salt, a pyridinium sulfonium salt, an alkylpyrrolidinium salt, and an alkyl quaternary salt.

More specifically, after the optical element having the adhesive layer was placed in an environment of 50% RH at 23 ° C for 7 days, the optical element was cut to a width of 25 mm. The cut sample was then bonded to a glass piece for autoclaving for 2 minutes at a lower pressure of 5 kg/cm2. Subsequently, the adhesion of the sample was measured using a tensile tester according to the following conditions according to jis ZC^37. The peeling speed was 0.3 m/min and the peeling angle was 18 〇. The temperature was 23 ° C, an environment of 5 % RH to evaluate the adhesion of the adhesive layer. The binder composition of the present invention comprises a base polymer and comprises an ionizing electrostatic agent. The base polymer can be prepared by copolymerizing a halogen-containing acid vinegar with (meth) propyl. Therefore, the dot-agent (iv) (meth)acrylic acid, or the antistatic agent ==, the adhesive composition of the present invention can be used to make eight adhesives having excellent antistatic properties. Floor. The adhesive group of the exemplary embodiment of the month is expected to have a thin layer of electricity of from 1 χ 1 〇 8 to W. 11 Illustrator of the exemplary implementation == excellent antistatic properties. According to the present invention, the (meth)propane-group element is electrically negative == 21 1378980 degrees negatively charged and makes the ionic compound easy to migrate in the binder layer. In addition, the adhesive composition according to an exemplary embodiment of the present invention is preferably used to form an adhesive layer having high transparency and preventing the contamination and/or corrosion resistance of the optical sheet coated with the adhesive layer, thereby not This will degrade the optical performance of the sheet. Therefore, the adhesive composition of the present invention is suitable for forming a binder layer for an optical element. Moreover, the adhesive composition table I according to the exemplary embodiment of the present invention exhibits excellent transparency, and the base polymer in the binder composition contains at least one (fluorenyl) acrylate as a main component. The base polymer has a weight average molecular weight of 1,000,000 to 2,000,000 and a gel fraction of 50 to 80%. Therefore, if a binder composition is used as the adhesive layer of the optical member, the adhesive layer has an adhesive property sufficient to be preferably applied to the optical member. If a binder composition containing a decane coupling agent is used to form the binder layer of the optical element 15, a chemical bond is formed between the calcining coupling agent and the functional group on the surface of the substrate to be coated. This results in an increase in the bond strength at the interface between the adhesive layer and the substrate. Therefore, even if the coefficient of thermal expansion of the substrate to be coated and the optical sheet are significantly different, the stress is concentrated at the interface 20 between the adhesive layer and the substrate due to the difference in thermal expansion coefficient between the adhesive layer and the substrate, thereby reducing the application. The stress on the optical sheet. The invention is better understood by the following examples, which are not to be construed as limiting the scope of the invention. 22 EXAMPLES First, the method of preparing the binder compositions according to Examples 1 to 11 and Comparative Examples i to 7 will be described in detail. Further, in the following description X, a method of mounting the optical elements according to Embodiments 1 to 1 and Comparative Examples 1 to 7 will be described, for example, which includes applying a binder composition to a polarizer. Performance testing was performed on each manufactured optical component. The ratio of the composition of the drum copolymer of Example 1 was 98.49 parts by weight of butyl acrylate, 1 part by weight of 2-hydroxyethyl acrylate, and 0.5 part by weight of (mercapto) acrylate as a halogen-containing element ( The propylene difluoride and the 120 parts by weight of ethyl acetate as a solvent were placed in a flask equipped with a reflux condenser and a stirrer, and heated to 65 under a nitrogen atmosphere. (: 〇. 〇 4 parts by weight of AIBN was added as a polymerization initiator' and the polymerization was allowed to proceed for 6 hours while maintaining the same temperature of 65. After the completion of the polymerization, the ionic compound was added in an amount of 1 part by weight. That is, 1-hexyl-3-mercaptoimidazolium hexafluorophosphate was added to the reaction product. To control the viscosity of the product, 28 parts by weight of ethyl acetate was additionally added thereto. Then, the product was cooled to room temperature to obtain inclusion. a copolymer composition solution (referred to as "copolymer solution") of the binder composition of Example 1. The concentration of the binder composition in the copolymer solution is about 2% by weight, and the viscosity of the copolymer solution is 4 〇〇〇 mpas. The expression indicates the mixing ratio of the components in the binder composition, the concentration of the binder composition in the copolymer solution, and the viscosity of the copolymer solution. 1378980 The weight average molecular weight of the base polymer was determined by GPC.
