    Abstract: 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.

    Abstract: Methods of forming multilayer reflective polarizers are described. One method includes providing a multilayer polymer film having a plurality of alternating polymeric optical layer pairs, heating the multilayer polymer film to a temperature of about or greater than both polymers layer glass transition temperatures to from a heated multilayer film, and stretching the heated multilayer polymer film in an in-plane direction to form a multilayer reflective polarizer. Each first polymer layer includes a first polyester material and each second polymer layer includes a second polyester material that has a different polymer composition than the first polymer layer composition. The stretching includes a uniaxial stretch.
