Zusammenfassung:PROBLEM TO BE SOLVED: To prepare an adhesive tape for preparing plastic lenses which inhibits the generation of bubbles, clouding or leakage in lens resins. SOLUTION: This adhesive tape for preparing plastic lenses is prepared by laminating an adhesive on a base material, wherein the base material is a multi-structural base material comprising a plastic film and silicon oxide. Furthermore, the adhesive is an addition-reactive silicone adhesive added with a condensation-reactive silicone adhesive from which low-molecular weight siloxanes are removed by depressurization.
