Embodiment 1
[0172] (Preparation of the polymer forming the adhesive layer)
[0173] After installing a three-way stopcock on a 2L three-necked flask and replacing the inside with nitrogen, 868g of toluene, 43.4g of 1,2-dimethoxyethane, 60.0g of 40.2mmol of isobutylbis(2, A toluene solution of 6-di-tert-butyl-4-methylphenoxy)aluminum was added, and 3.68 g of a mixed solution of cyclohexane and n-hexane containing 6.37 mmol of sec-butyllithium was further added. Next, 51.5 g of methyl methacrylate (MMA) was added thereto, and stirred at room temperature for 60 minutes. Then, the internal temperature of the polymerization solution was cooled to -30° C., and 240 g of n-butyl acrylate (nBA) was added dropwise over 2 hours. Next, 51.5 g of methyl methacrylate was added, and after stirring overnight at room temperature, 3.50 g of methanol was added to stop the polymerization reaction. The obtained reaction solution was poured into methanol, and the precipitate was collected by filtration. By ...
Embodiment 2～4
[0190] In Example 1, except that the PET film with the thickness shown in Table 1 was used instead of the PET film with a thickness of 25 μm as the film substrate, the same operation as Example 1 was performed to produce a transparent conductive film with an adhesive layer. film, and subsequent patterning and crystallization.
Embodiment 5
[0192] In Example 1, the PET film with a thickness of 75 μm was used instead of the PET film with a thickness of 25 μm as the film substrate, and the thickness of the adhesive layer was changed from 25 μm to 150 μm. In operation, a transparent conductive film with an adhesive layer is produced, followed by patterning and crystallization.
