  • Table 1 shows polymethyl methacrylate (PMMA, Tg: 105 ° C.) or a butadiene-based polymer (TH-21 (manufactured by DENKA CORPORATION, trade name), Tg: 83 ° C.) instead of (meth) acrylic elastomer. Except having changed into the compounding quantity, it carried out similarly to Example 1, and obtained the 1st liquid and the 2nd liquid.
  • PMMA polymethyl methacrylate
  • TH-21 manufactured by DENKA CORPORATION, trade name
