Claims51
An optical element comprising a polymer film containing a dispersion of minute layered particulates in a polymeric binder and microvoids, wherein the polymer film comprises a polyester.
An optical element comprising a polymer film containing a dispersion of minutes layered particulates in a polymeric binder and microvoids wherein the microvoids contained crosslinked polymer beads.
An optical element comprising a polymer film containing a dispersion of minute layered particulates in a polymeric binder and microvoids wherein said layered particulates comprise smectite clay.
An optical element comprising a polymer film containing a dispersion of minute layered particulates in a polymeric binder and microvoids wherein said layered particulates comprise intercalated smectite day that comprises block copolymer intercalated in the smectite clay in which the block copolymer comprises a hydrophilic block that intercalates day wherein said hydrophilic block comprises poly(ethylene oxide).
