Polymeric compositions and articles with anisotropic light scattering and methods of making and using

An article, comprising:

• a substrate;
• and
• a polymeric composition disposed on the substrate, the polymeric composition comprising
• adhesive material;
• and
• dispersed phase material disposed as a plurality of elongated structures within the adhesive material, each elongated structure having a major axis, wherein the major axes of the elongated structures are substantially aligned and the dispersed phase material has an index of refraction that differs by at least 0.01 from an index of refraction of the adhesive material.

An article, comprising:

• a medium configured and arranged to contain light;
• a light extraction element disposed on at least a portion of the medium, the light extraction element comprising
• adhesive material in contact with the medium, wherein the adhesive material has an index of refraction that differs by no more than 0.3 from an index of refraction of the medium;
• and
• dispersed phase material disposed as a plurality of elongated structures within the adhesive material, each elongated structure having a major axis, wherein the major axes of the elongated structures are substantially aligned and the dispersed phase material has an index of refraction that differs by at least 0.01 from an index of refraction of the adhesive material.
