[0192] Example 1
[0193] (a) Preparation of water-based adhesive
[0194] 3 parts of carboxy-modified polyvinyl alcohol ("KL-318" obtained from Kuraray Co., Ltd.) was dissolved in 100 parts of water, and 1.5 parts of polyamide epoxy resin (from "Sumiraze Resin 650 (30)" available from Sumika Chemtex Co., Ltd., an aqueous solution with a solid content concentration of 30%) to prepare a water-based adhesive.
[0195] (b) Production of retardation film
[0196] A styrene-maleic anhydride-based copolymer resin (“Dylark D332” (trade name) sold by Nova Chemical Co., Ltd., Tg=131° C.) was used as a core layer, and acrylic rubber particles having an average particle diameter of 200 nm were mixed with about 200 nm in diameter. 20% methacrylic resin (resin used in "Technoloy S001" (trade name) sold by Sumitomo Chemical Co., Ltd., Tg=105°C) as a skin layer was coextruded in three layers to obtain a core The resin three-layer film of the skin layer was formed on both sides of the laye...
