[0091] In the preparation of the acrylic polymer, a polymerization initiator such as a photopolymerization initiator or a thermal polymerization initiator can be used depending on the type of polymerization reaction. The photopolymerization initiator is not particularly limited as long as it can initiate photopolymerization, and for example, benzoin ether photopolymerization initiators, acetophenone photopolymerization initiators, α-keto alcohol photopolymerization initiators, Aromatic sulfonyl chloride-based photopolymerization initiators, photoactive oxime-based photopolymerization initiators, benzoin-based photopolymerization initiators, benzil-based photopolymerization initiators, benzophenone-based photopolymerization initiators, ketals Photopolymerization initiators, thioxanthone-based photopolymerization initiators, acylphosphine oxide-based photopolymerization initiators, and the like. As the thermal polymerization initiator, for example, azo-based initiators, peroxide...
Embodiment 1
[0198] The above-mentioned pressure-sensitive adhesive sheet A1 was bonded to the exposed surface of the polarizer of the single-sided protective polarizing plate using a roll laminator. Furthermore, the above-mentioned PSA sheet K1 was laminated on the PSA sheet A1 using a roll laminator. Then, the above-mentioned cell-side pressure-sensitive adhesive sheet was bonded to the polycycloolefin protective film protecting the polarizing plate on one side using a roll laminator. In this way, a transparent protective film with a laminated adhesive sheet comprising the adhesive sheet A1 and the adhesive sheet K1 on the side of the exposed surface of the polarizer that protects the polarizing plate on one side and protects the polarizing plate on one side is obtained. A double-sided adhesive-coated polarizing plate with a cell-side adhesive sheet on the film attachment surface.
Embodiment 2~7、 comparative example 1~3
[0200] A polarizer with an adhesive on both sides was obtained in the same manner as in Example 1 above, except that the composition of the front side adhesive sheet attached to the exposed surface of the polarizer of the single-sided protective polarizing plate was changed as shown in Table 3. plate.
