[0254] The following examples are given to illustrate the present invention in more detail. Of course, the present invention is not limited by the following examples. It can also be implemented with appropriate changes within the scope that conforms to the above and later gist. These solutions are all included in the present invention. Within the scope of technology.
[0255] In addition, as for the sample for measuring the physical properties of the film, the sample was taken from the center part in the width direction.
[0256]
[0257] The weight average molecular weight is determined by gel permeation chromatography (GPC) under the following conditions.
[0258] System: GPC system HLC-8220 manufactured by Tosoh
[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] (Production Example 1-1 [Resin composition for forming base layer (A-1)])
[0282] In a reactor equipped with a stirring device, a temperature sensor, a condenser, and a nitrogen introduction tube, 40 parts by weight of methyl methacrylate (MMA) and 10 parts by weight of 2-(hydroxymethyl) methyl acrylate (MHMA) are added as The polymerization solvent was 50 parts by weight of toluene and 0.025 parts by weight of an antioxidant (manufactured by ADK STAB2112, ADEKA), and the temperature was raised to 105° C. while blowing nitrogen gas therein.
[0283] When the reflux started with the temperature rise, 0.05 parts by weight of tert-amyl peroxide isononanoate (manufactured by ARKEMA Yoshitomi, Ltd., trade name: luPerOX570) was added as a polymerization initiator, and the above isoperoxide was added dropwise over 2 hours. 0.10 parts by weight of tert-amyl nonanoate was subjected to solution polymerization under reflux at about 105 to 110°C, and further matured for 4 hours.

[0290] (Manufacturing Example 1-2 [Resin composition for base layer formation (A-2)])
[0291] In a reactor equipped with a stirring device, a temperature sensor, a condenser, and a nitrogen introduction tube, 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 A mixed solvent of 22.5 parts by weight of methanol and 0.05 parts by weight of an antioxidant (manufactured by ADK STAB2112, ADEKA) were heated to 73°C while nitrogen gas was introduced into the reactor. At the time 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 was added to the reactor, and while dissolving the above-mentioned dimethyl-2,2'-azobis(2-methyl) in a mixed solvent of 7.3 parts by weight of toluene and 1.8 parts by weight of methanol over 2 hours Propyl ...
