    • A sheet comprising: (1) a core member comprising one or more layers and having a first major surface and (2) a slip control layer disposed on at least a portion of the first major surface, wherein the slip control layer comprises: (i) a footing layer disposed on at least a portion of the first major surface of the core member, (ii) a binder layer disposed on the footing layer, and (iii) an array of particles disposed in the binder layer and footing layer and protruding therefrom, wherein the average diameter of the particles is greater than the combined thickness of the foot layer and binder layer. A process for making such a sheet comprising: (1) providing a core member; (2) forming a footing layer on at least a portion of the first major surface of the core member, wherein the footing layer is viscoelastic and has a Tg that is lower than either the Tg or the Tm of the polymer at the first major surface of the core member; (3) applying a binder layer composition comprising a film forming polymer and particles to the surface of the footing layer; then (4) tentering the assembly under sufficient heat to soften the footing layer such that the particles sink into the footing layer, wherein the average diameter of the particles is greater than the combined thickness of the footing layer and binder layer.
    • 一种片,其包括:(1)包括一层或多层并具有第一主表面的芯构件和(2)设置在所述第一主表面的至少一部分上的防滑层,其中所述防滑层包括:(i )设置在所述芯构件的第一主表面的至少一部分上的基脚层,(ii)设置在所述基底层上的粘合剂层,以及(iii)设置在所述粘合剂层和基脚层中的颗粒阵列,并且突出 其中颗粒的平均直径大于底层和粘合剂层的组合厚度。 一种制造这种片的方法,包括:(1)提供芯构件; (2)在所述芯构件的第一主表面的至少一部分上形成基脚层,其中所述基脚层是粘弹性的并且具有低于所述第一主表面处的所述聚合物的Tg或Tm的Tg 的核心成员; (3)将包含成膜聚合物和颗粒的粘合剂层组合物施加到基底层的表面; 然后(4)在足够的热量下拉伸组件以软化基底层,使得颗粒沉入基底层,其中颗粒的平均直径大于基底层和粘合剂层的组合厚度。
