[0254] The following examples are listed below to describe the present invention more specifically. The present invention is certainly not limited by the following examples, and can also be appropriately modified and implemented within the scope of meeting the aforementioned and later-described gist. These solutions are all included in the scope of the present invention. within the technical range.
[0255] In addition, the sample for the measurement of a film physical property was taken from the center part of the width direction.
[0256]
[0257] The weight average molecular weight was determined by gel permeation chromatography (GPC) under the following conditions.
[0258] System: GPC system HLC-8220 manufactured by Tosoh Corporation
[0259] Developing solvent: Chloroform (manufactured by Wako Pure Chemical Industries, special grade), flow rate: 0.6ml / min
[0260] Standard sample: TSK standard polystyrene (manufactured by Tosoh Corporation, PS-Oligomer kit)

manufacture example 1-1
[0281] (Manufacture Example 1-1 [Resin Composition for Substrate Layer Formation (A-1)])
[0282] In the reaction kettle equipped with stirring device, temperature sensor, condensation pipe and nitrogen inlet pipe, add 40 parts by weight of methyl methacrylate (MMA), 10 parts by weight of 2-(hydroxymethyl) methyl acrylate (MHMA), as 50 parts by weight of toluene as a polymerization solvent and 0.025 parts by weight of an antioxidant (ADK STAB2112, manufactured by ADEKA Corporation) were heated up to 105° C. while blowing nitrogen gas thereinto.
[0283] When the reflux started as the temperature rose, 0.05 parts by weight of tert-amyl peroxyisononanoate (manufactured by ARKEMA Yoshitomi, Ltd., trade name: luPerOX570) was added as a polymerization initiator, and the above-mentioned isononanoate was added dropwise over 2 hours. Solution polymerization was performed under reflux at about 105 to 110° C. while 0.10 parts by weight of tert-amyl nonanoate, and aging was further perfo...
manufacture example 1-2
[0290] (Manufacture Example 1-2 [Resin Composition for Substrate Layer Formation (A-2)])
[0291] In a reaction kettle equipped with a stirring device, a temperature sensor, a condensation pipe and a nitrogen gas introduction pipe, 79.4 parts by weight of methyl methacrylate (MMA), 20.6 parts by weight of methacrylic acid (MAA), and 90.0 parts by weight of toluene as a polymerization solvent were added With a mixed solvent of 22.5 parts by weight of methanol and 0.05 part by weight of an antioxidant (ADK STAB2112, manufactured by ADEKA Corporation), the temperature was raised to 73°C while blowing nitrogen into the reactor. At the point when the reflux starts as the temperature rises, dimethyl-2,2'-azobis(2-methylpropionate) (manufactured by Wako Pure Chemical Industries, Ltd., trade name: V- 601) 0.25 parts by weight were added to the reaction kettle, and the above-mentioned dimethyl-2,2'-azobis(2-methanol) was dissolved in a mixed solvent of 7.3 parts by weight of toluene an...
