These crosslinking agents may be used singly or in combination of two or more kinds thereof. The amount of the crosslinking agent can be suitably determined in consideration of the balance between the crosslinking agent and the base polymer to be crosslinked, and more preferably considering the use of the optical member. In order to obtain a high thermal resistance of the base polymer by the cohesiveness of the acrylic adhesive, it is usually possible to crosslink with respect to 100 parts by weight (wt. part) of the base polymer of not less than 0.01 wt. The agent is added to the base polymerization oxime. Alternatively, the amount of the crosslinking agent combined with the base polymer is preferably 5 wt. parts or less with respect to 100 wt. parts of the base polymer in view of flexibility and/or adhesion. 20 The base polymer contained in the binder composition according to the present invention has a degree of crosslinking of 50 to 80% in terms of gel fraction rate. If the gel fraction is within this range, the base polymer can improve the adhesion of the binder composition. When immersed in ethyl acetate at 25 ° C for one day, the gel fraction can be estimated by the following 17 200925229 equation based on the weight of the initial weight and the impregnation and drying of the binder composition: gel fraction = impregnation Weight/dry weight after drying X100 mixing ratio 5 The ratio of the total weight of the combination of the antistatic agent (B) and the base polymer (A) and the antistatic agent (B) is preferably 0.01 to 5 wt%, more preferably 0.05 to 2 wt%. When the ratio is less than 0.01 wt%, the binder composition does not have a satisfactory antistatic effect. If the ratio is from 0.01 to 5 wt%, the binder composition of the present invention has an economic advantage from the viewpoint of preparation. 10 Other Components The adhesive composition according to an embodiment of the present invention may further comprise various additives in various forms known in the art, such as powders, granules and/or foils, depending on the application thereof, without specifically limiting the additives, including: for example, Thickeners, 15 surface lubricants, leveling agents, antioxidants, corrosion inhibitors, light stabilizers, UV absorbers, polymerization inhibitors, decane coupling agents, inorganic or organic fillers, ruthenium powders, pigments, and the like. Preparation of Binder Composition 20 A method for preparing a binder composition according to an exemplary embodiment of the present invention can be exemplified by the following two methods: One of the methods is, for example, in an organic solvent, Mixing together different types of monomers as starting materials for the base polymer, the organic solvent having a boiling point of about 120 ° C or less, such as ethyl acetate, toluene, C18 200925229 ketone, hexane, alcohol, The polymerization of the monomer is then initiated by the addition of a polymerization initiator thereto to produce a base polymer. The resulting base polymer can be obtained in a solution state which dissolves and/or swells in an organic solvent. Then, an antistatic agent containing an ionic compound is added to an organic solvent containing the base polymer and uniformly mixed with the base polymer. Thereafter, the prepared mixture is mixed with a crosslinking agent to crosslink the base polymer, and if necessary, at least one selected from a conventionally added agent such as a decane coupling agent. As a result, the binder composition of the present invention was prepared as a final product. 10 The binder composition is easily used to form a binder layer by applying a binder composition to a substrate and drying the coated substrate. Another of the methods is, for example, mixing together different types of monomers as a base polymer raw material in an organic solvent such as ethyl acetate, and simultaneously adding an antistatic agent containing an ionic compound thereto. A polymerization initiator was also added to the mixture to initiate polymerization of the monomer, thus obtaining a base polymer containing an antistatic agent. Similar to the first method, the resulting base polymer can be obtained in a solution state in which hydrazine is dissolved and/or swollen in an organic solvent. Thereafter, a crosslinking agent is added to the resulting solution of the base polymerization 20 and the antistatic agent contained in the organic solvent to crosslink the base polymer, and if necessary, subsequently add at least one coupling such as decane selected from a conventional additive. Agent. As a result, the binder composition of the present invention was prepared as a final product. Like the first method, the binder composition forms a layer of adhesive when the binder composition is applied to the substrate and then the coated substrate is dried. 19 200925229 As disclosed above, with regard to the preparation of the binder composition of the present invention, the antistatic agent can be added to the base polymer after the preparation of the base polymer 'or 'antistatic agent can be prepared in the base polymer It is added to the base polymer during the period. In order to obtain a homogeneous mixture of the antistatic agent and the base polymer, the 5 antistatic polymer is preferably soluble in an organic solvent such as ethyl acetate. Optical Element 光学 An optical element according to an exemplary embodiment of the present invention includes an optical sheet and an adhesive layer formed using the adhesive composition of the present invention, the adhesive layer being more typically transmitted at a thickness of 3 to 200 μm The thickness is applied to each side of one side or both sides of the optical sheet. The adhesive layer is usually applied to the optical sheet by directly applying the adhesive layer to the optical sheet. Alternatively, the adhesive layer can be applied first to other base impurities (such as a release liner) and then transferred to an optical sheet. 15 The application and application of the adhesive layer can be carried out by various methods for manufacturing the adhesive, including, for example, roll coating, gravure coating, reverse coating, light brushing, spraying , airknife coating, die coating, etc. The optical sheet used in the present invention is not particularly limited as long as it can be applied to 20 to manufacture different displays, which may include, for example, a polarizing mirror, a phase contrast plate, a brightness enhancement plate, an anti-glare plate, and the like. Moreover, the optical sheet may also comprise a laminate of at least two optical layers, such as a laminate of #% clock phase liners, using two or more phase-formed panels, polarizers, and brightness enhancement. Laminate or laminate of anti-glare plates #. 20 200925229 5 The adhesive layer (ie, the binder composition) formed on the optical sheet exhibits an adhesive strength of 1 to 15 (N/25 mm), more preferably 5 to 1 〇 (Ν/25_). It is considered that the bonding strength of 1 to 15 (office) is sufficient to achieve an advantage for optical components. The bond strength can be measured and evaluated according to the known test method IIS ζ〇 237 for adhesive tapes and adhesive sheets. More specifically, the optical element with the bond was placed after 7 days at 5 〇 Ο 10 15 ❹ 20 RH at 23 t, and the optical element was cut to a width of $25 dirty. The cut sample was then adhered to a glass piece for two minutes of treatment at 5 Torr and a pressure of 5 kg/cm. Subsequently, the adhesion tester was measured according to the following conditions according to the melon Z 〇 = 3 7 ': the peeling speed was 〇·3 m/min, and the peeling 隹 angle was 18 〇. The temperature was 23 ° C, 50% RH environment to evaluate the adhesion of the adhesive layer. The binder composition of the present invention comprises a base polymer and an antistatic agent comprising an ionized mouth material. The base polymer can be copolymerized with a (meth)acrylic acid and a (meth) propyl group containing a functional group element. Dilute vinegar to prepare. Therefore, if it is compared with the binder composition of the (meth)acrylic acid-free and/or antistatic agent which does not contain _ group 7 〇 〇, it can be used for preparation with excellent resistance. A layer of adhesive for electrostatic properties. More specifically, when the adhesive composition according to the exemplary embodiment of the present invention is applied to a substrate, that is, an optical sheet to form a yarn, the adhesive layer has a thickness of about Ιχΐ0 (Ω/□), more preferably lxl〇8. The desired sheet resistance to 1χ1〇11 (Ω/〇) thus exhibits excellent antistatic properties. According to the present invention: No, the antistatic property of the adhesive composition of the m embodiment may be caused by a halogen element encapsulated in (mercapto)acrylic acid vinegar, and the tooth group element is high 21 200925229 degree negatively charged and makes the ionic compound Easy to migrate in the adhesive 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 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 decane coupling agent and the functional group on the surface of the substrate to be coated. This results in an increase in the bond strength 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 200925229 EXAMPLES First, a method of preparing the binder compositions according to Examples 1 to 11 and Comparative Examples 1 to 7 will be described in detail. Further, in the following description, a method of manufacturing the optical elements according to Embodiments 1 to 11 and Comparative Examples 1 to 7 will be explained, for example, which includes applying a binder composition to a polarizing mirror. Performance testing was performed on each manufactured optical component. Preparation Example 1 of the copolymer composition of Example 1 ίο 98.49 parts by weight of butyl acrylate, 1 part by weight of 2-hydroxyethyl acrylate, 0.5 parts by weight of a halogen group-containing (fluorenyl group) Acrylic acid (al) trifluoroethyl acrylate and 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 ° C under a nitrogen atmosphere. To this was added 4 parts by weight of AIBN as a polymerization initiator, and polymerization was allowed to proceed for 6 hours while maintaining the same temperature at 65 °C. After the completion of the polymerization, an ion © compound, 1-hexyl-3-mercaptoimidazolium hexafluorophosphate, was added to the reaction product in an amount of 0.01 part by weight. In order to control the viscosity of the product, 280 parts by weight of ethyl acetate was additionally added thereto. Then, the product was cooled to room temperature to obtain a copolymer composition solution (referred to as "copolymer solution") containing the binder composition according to Example 20 of Example 1. The concentration of the binder composition in the copolymer solution was about 20% by weight, and the viscosity of the copolymer solution was 4000 mPa.s.
