比較例1は、ビニル重合体(A1)を含まない例であり、異種基材間の接着性が不良であった。比較例2は、ビニル重合体(A1)及びポリエステル樹脂(A2)が複合化されていない例であり、特に、PETとPVCの接着性が十分に満足できるものではなかった。比較例3は、ポリエステル樹脂(A2)を含まない例であり、異種基材間の接着性が不良であった。
Comparative Example 1 is an example in which the vinyl polymer (A1) is not contained, and the adhesiveness between different kinds of substrates is poor. Comparative Example 2 is an example in which the vinyl polymer (A1) and the polyester resin (A2) are not composited, and in particular, the adhesiveness between PET and PVC was not sufficiently satisfactory. Comparative Example 3 is an example in which the polyester resin (A2) is not contained, and the adhesiveness between different kinds of substrates is poor.
