ABSTRACT:
A wound laminate obtained by laminating a plastic film composed of an aromatic polycarbonate comprising bisphenol A as an aromatic dihydroxy component, and a protective film composed of an aromatic polyester, using an intervening adhesive having a weak adhesive strength of 3-50 gf (0.0294-0.49 N), and winding the laminate. The wound laminate is used as a transparent protective layer (protective film) for an optical disk to fabricate a film surface side-incident optical disk.
