摘要：
A pressure-sensitive adhesive consisting of a homogeneous mixture of at least one natural rubber component and at least one polyacrylate component displays significantly improved properties in cohesion and aging and weathering resistance compared to the individual components. Particularly good properties are achieved when the adhesive contains x % by weight of at least one natural rubber component, y % by weight of at least one polyacrylate component, v % by weight of at least one adhesive resin component and w % by weight of additives, where 10≦×x≦80, 10≦y
