Provided is an oriented polymeric sheet comprising a photochromic-dichroic material, wherein the sheet exhibits dichroism in an activated state. Also provided is a multilayer composite comprising at least a support layer; and an oriented thermoplastic polymeric sheet having two opposing surfaces and comprising a photochromic-dichroic material. The sheet exhibits dichroism in an activated state. At least one surface of the sheet is connected to at least a portion of the support layer. The present invention also relates to an optical element comprising the multilayer composite. Related methods also are disclosed.

Oriented polymeric sheets exhibiting dichroism and articles containing the same

A coating formulation for a substrate having abstractable hydrogen radicals is disclosed. The formulation includes a hydrophilic polymeric component comprising at least two polymeric species of differing molecular weights, an unsaturated hydrophilic monomer capable of free-radical polymerisation in the presence of a radical and a UV activatable compound capable of abstracting hydrogen radicals from the surface to be coated and from a polymeric specie of the hydrophilic polymeric component so as to initiate and promote the cross-linkage of the monomer to the surface and of the monomer or a propagating monomer chain to a polymeric specie of the polymeric component, and a suitable solvent to give the formulation a desired viscosity.
