Embodiment
[0073] Hereinafter, the laminated film of the present invention and its manufacturing method will be described in detail using examples and comparative examples, but the present invention is not limited to the following examples.
Synthetic example 1
[0074] [Synthesis Example 1: Production of Curable Resin Used in Forming the First Layer (Inner Layer)]
[0075] The cage silsesquioxane resin used to form the inner layer material can be synthesized as follows by the method described in JP-A-2004-143449.
[0076] 40 ml of 2-propanol (IPA) as a solvent and 3.1 g of a 5% tetramethylammonium hydroxide aqueous solution (TMAH aqueous solution) as a basic catalyst were placed in a reaction vessel equipped with a stirrer, a dropping funnel, and a thermometer. 15 ml of IPA and 12.7 g of 3-methacryloxypropyltrimethoxysilane were put into the dropping funnel, and 3-methacryloxypropyltrimethoxysilane was added dropwise at room temperature over 30 minutes while stirring the reaction vessel. Oxysilane solution in IPA. After the dropwise addition of 3-methacryloyloxypropyltrimethoxysilane was completed, it was slowly returned to room temperature and stirred for 2 hours without heating. After stirring, IPA was removed under reduced pressu...

[0077] [Synthesis Example 2: Production of Curable Resin Used in Forming the Second Layer (Outer Layer)]
[0078] The cage-type silsesquioxane-containing curable silicone copolymer used for forming the outer layer material can be synthesized as follows by the method described in JP-A-2009-227863.
[0079] 250 ml of toluene and 52.5 g of phenyltrichlorosilane were placed in a reaction vessel, and cooled to 0°C. Appropriate amount of water was added dropwise and stirred until the hydrolysis was completed. After washing the hydrolyzate with water, 8.3 ml of a commercially available 30% benzyltrimethylammonium hydroxide solution was added, and the mixture was heated at reflux temperature for 4 hours. The whole was then cooled and left to stand for about 96 hours. The slurry obtained after the lapse of this time was heated again at reflux temperature for 24 hours, then cooled, and filtered to obtain 37.5 g of octaphenylsilsesquioxane as a white powder.
