Embodiment 1
[0168]
[0169] In a four-necked flask with a stirring blade, a thermometer, a nitrogen inlet tube and a condenser, 100 parts by weight of 2-ethylhexyl acrylate (2EHA), 10 parts by weight of 4-hydroxybutyl acrylate (HBA), 0.2 parts by weight 2,2'-Azobisisobutyronitrile and 205 parts by weight of ethyl acetate as a polymerization initiator, nitrogen gas was introduced while stirring slowly, and the liquid temperature in the flask was kept at about 63°C for about 4 hours. Polymerization reaction, Thus, an acrylic polymer (A1) solution (about 35% by weight) was prepared. The acrylic polymer (A1) had a weight average molecular weight of 600,000 and a Tg of -67°C.
[0170]
[0171] The above-mentioned acrylic polymer (A1) solution (about 35% by weight) was diluted to 29% by weight with ethyl acetate, and 4 parts by weight of trimethylol was added to 100 parts by weight (solid content) of the acrylic polymer in the solution. Propane / toluene diisocyanate trimer adduct (manufactu...
Embodiment 2~20、 comparative example 1~2
[0175] As shown in Table 1 and Table 2, the types or compounding amounts of the monomer components constituting the acrylic polymer, the crosslinking agent constituting the adhesive composition, the catalyst, and the keto-enol tautomeric compound were changed. Except that, the carrier film for transparent conductive films was produced by the method similar to Example 1.
