Persulfate-based starting chambers such as osmium persulfate and persulfate, such as fluorenyl peroxide, tertiary butyl hydroperoxide, and peroxygen initiators; for example, ethyl substituted with phenyl取代 Replaced ethane-based initiators; for example, carbonyl-based initiators such as aromatic carbonyl compounds; for example, combinations of persulfate and sodium bisulfite, peroxides and sodium ascorbate, etc. . These polymerization initiators may be used alone or in combination. The blending ratio of these polymerization initiators is about 0.005 to 1 part by weight based on 100 parts by weight of the monomer mixture. Furthermore, water can be added only when the emulsion is prepared, or added later, and it can be appropriately selected depending on the polymerization method described below. Also, although there is no particular limitation on the mixing ratio of water, it is advisable to adjust the solid content concentration of the acrylic polymer after the emulsion polymerization to, for example,% to even% by weight, and to adjust it to 35 to 70% by weight. % Is better. If necessary, a chain transfer agent and a cross-linking agent can be appropriately blended in these emulsions. 316587 13 200524998 Regarding the bond transfer, xA np t…, special restrictions, for example, u acetic acid, acetic acid, paper sugar, _, / 7L stone claw alcohol, acetic acid, mirror alcohol, and acetic acid 2 _ Ethyldidecyl, thiol such as 1-propanol. Eryuji These chain transfer agents can be used alone or in combination. The formulation ratio of the agent is chain transfer from 0.00 to 0.5 parts by weight relative to the monomer mixture. Ritchie 'is, for example, about a crosslinking agent, which is not particularly limited, and examples thereof include a crosslinking agent and a metal chelate-based crosslinking agent. In addition, it is possible to use "," and "parent" monomers as crosslinking agents. These silane-based crosslinking agents may be used alone or in combination. In addition, the blending ratio is 5 parts by weight based on 10 parts of the monomer mixture. For example, it is about 0.01 to more. As for other additives, examples include buffers, neutralizers, foam inhibitors, and stabilizers. Well-known compounds used as agents. Addition of pore-forming compound As for the method of emulsification polymerization, the Yi Te 殃 method, Quan Jin m…, the limitations of Zhishu ’can be selected from the entire batch of polymerization. In the + σ method, for example, in the whole batch polymerization method, the monomer is mixed with the agent and water U in the reaction capacity H, and then emulsified by mixing with money; ^ after coating into a pore liquid, the reaction container in. Water was added at the time to run the emulsion polymerization. "The starter is needed, for example, in the full-drop method, firstly add the monomer mixture, trans 3] 6587 14 200524998 responsive emulsifier and water, and emulsify it by mixing the mixture and the mixture. It is prepared as a drop solution, and at the same time, the reaction container is filled with ψ, Ru Xin ..., and I σ starter and water are added, and then the drop solution is dropped into the reaction valley to perform emulsion polymerization. Such an emulsion polymerization polymerizes the monomer mixture to synthesize an acrylic polymer, and the acrylic polymer is emulsified in water to obtain an acrylic polymer emulsion. Then, the acrylic polymer emulsion obtained in this way is obtained. The Shibuya coupling agent is blended in the mixture to prepare an adhesive composition for an optical element of the present invention. Examples of the Shibuya coupling agent include 3-glycidyloxypropyl 2 bis f: xi :, 3 · Glycidyloxypropylmethyl diethoxylate,-(3,4-earthylcyclohexyl) ethyltrimethoxyisolate, etc. H-containing agents containing epoxy groups; for example, 3-aminopropyl Trimethoxymethoxy 2 -aminoethyl n-methyldimethoxy, 3 _Triethoxyna (, monomethyl-butylene) propylamine and other amine-containing stone yaki couplings; for example, dilute: τpropyl trimethoxy group, "propyl propyl oxypropyl ^ milk group" And other (meth) propyl-containing materials coupling agents; for example, 3_ = acid propyl (3-1SGey__Gp multiplied by ethoxy group and other silane-containing silane coupling agents. By using these Shiyaki couplings, It can improve the durability. It is suitable for both use and combination. Also, the blending ratio of Shi Xi Shao Ping: is 001 to 100 parts by weight based on 100 parts by weight of the solid content of the acid polymer emulsion based on 100 parts by weight of the monomer mixture. 0310.5 parts by weight is better. If it is less than 0.01 parts by weight, it will be improved; if it exceeds 1 part by weight, the re-peelability cannot be improved. 3] 6587) 5 200524998, high. A known additive such as an ultraviolet absorber A may be added to the adhesive group for an optical element of the present invention, and h 'may be added, a filler, and the like. It prevents the adhesive composition for optical elements of the present invention obtained from softening swords, dyes, and pigments, and is durable in heat-resistant and moisture-resistant materials such as heat and moisture, and even though After long-term storage in the nuclear environment, it is still easy to peel off. The adhesive layer for optical elements used for excellent performance is attached to the liquid crystal display device. That is, the optical element of the present invention is used for the optical element. For example, after the material is applied, 表面 Γ ', and the cloth is peeled on the surface of the substrate dr to form an adhesive sheet for an optical element, and then the == sheet is transferred to the optical element, and the cost can be made.

Parallax films such as birefringent films and liquid crystal polymer films formed by stretching. Although the thickness of the phase difference film is not particularly limited, it is usually about 20 square centimeters. The phase difference film can be formed into two layers The laminated body of the above stretched film can also be formed to be capable of controlling optical characteristics such as phase difference.

The ellipsoidal polarizing film is used for compensating the phase difference of liquid crystal cells to prevent coloration and widen the viewing angle range. It can be obtained by, for example, laminating a polarizing film and a phase difference film. You can use laminated, pancreatic, phase-difference films after lamination, and also can be used as reflective polarizing films, semi-transmissive thin and polarized light. The two ultra-high-definition films can be used as optical compensation films and other various magnifying films, and they can also be used as films with improved brightness. The polarizing film can be used as an anti-glare sheet by providing a reflective sound having a fine uneven structure on its surface. That is, the adhesive layer for the optical element is attached to the optical part, for example, the adhesive layer for the optical element of the adhesive sheet for the element is pressed in a state that it is in contact with the optical part, and then the substrate is only peeled off from the optical part. . By this, for example, as shown in FIG. 2, the optical element 2 can be obtained by laminating the optical element 2 'on the early side of the optical component 4 (or both sides shown by the dotted line).
