[0366] Examples and comparative examples are shown below, and the present invention will be described in more detail. In addition, this invention is not limited to any Example and comparative example. In addition, specific numerical values such as compounding ratios (content ratios), physical properties, and parameters used in the following descriptions may be replaced with their corresponding compounding ratios (content ratios), The upper limit value (value defined in the form of "below" or "less than") or the lower limit value (value defined in the form of "above" or "exceed") of physical property values, parameters, etc.
[0367] In addition, "part" and "%" are mass standards unless otherwise indicated.
[0368] 1. Details of ingredients
[0369] Each component used in each Example and each comparative example is described below.
[0370] 2EHA: 2-Ethylhexyl Acrylate
[0371] MMA: methyl methacrylate
[0372] BA: butyl acrylate
[0373] NVP: N-Vinylpyrrolidone

Synthetic example 1
[0384] 63 parts by mass of 2-ethylhexyl acrylate (2EHA), 15 parts by mass of N-vinylpyrrolidone (NVP), methyl 9 parts by mass of methyl acrylate (MMA), 13 parts by mass of 2-hydroxyethyl acrylate (HEA), 0.2 parts by mass of azobisisobutyronitrile as a polymerization initiator, and 233 parts by mass of ethyl acetate as a solvent. Nitrogen, nitrogen replacement was performed for about 1 hour while stirring. Then, it heated to 60 degreeC, and it was made to react for 7 hours, and the solution of the adhesive polymer whose weight average molecular weight (Mw) was 1,200,000 was obtained.
[0385] In addition, the glass transition temperature of the adhesive polymer calculated by the FOX formula was -34°C.
[0386] Synthesis Example 2 to Synthesis Example 3
[0387] Except having changed the compounding recipe of a monomer component according to Table 1, it carried out similarly to the synthesis example 1, and produced the solution of an adhesive polymer.
[0388] 3. Preparation ...
Embodiment 1
[0390] To the solution of the adhesive polymer of Synthesis Example 1, 1.1 parts by mass of Takenate D-110N (benzenediol) as a crosslinking agent was added to 100 parts by mass of the adhesive polymer in the solution of the adhesive polymer 75% ethyl acetate solution of trimethylolpropane adduct of methylene diisocyanate, manufactured by Mitsui Chemicals Co., Ltd.), 100 parts by mass of the adhesive polymer in the solution of the adhesive polymer is 1 mass 2 parts by mass of BLACKND1 (leuco dye) as a compound colored by acid, 2 parts by mass of CP-310B as an acid generator with respect to 100 parts by mass of the adhesive polymer in the solution of the adhesive polymer (photoacid generator), uniformly mixed to prepare adhesive.
[0391] Next, on one surface of a polyethylene terephthalate film with a thickness of 50 μm after surface release treatment, the adhesive of Example 1 was coated with a jet roll so that the thickness after drying became 25 μm. , and dried at 130 °C fo...
