Abstract
The invention relates to an optical component comprising a dispersion of layered minute particulate materials in a binder, the layered materials having a layer thickness, a concentration of particulate in the binder, and a basal plane spacing sufficient to provide a component having a light transmissivity of at least 50%.
Claims43
An optical component comprising a dispersion of layered minute particulate materials in a binder, the layered materials having a layer thickness, a concentration of particulate in the binder, and a basal plane spacing sufficient to provide a component having a light transmissivity of at least 50% wherein said layered material comprises smectite clay or a layered double hydroxide.
A back lighted imaging media comprising an optical component comprising a dispersion of minute layered particulates in a binder, the particles having a layer thickness, a concentration of particulate in the binder, and a particulate basal plane spacing sufficient to provide a component having a light transmissivity of at least 50% wherein said layered material comprises smectite clay or a layered double hydroxide.
A liquid crystal device comprising an optical component comprising a dispersion of minute layered particulates in a binder, the particles having a layer thickness, a concentration of partictalate in the binder, and a particulate basal plane spacing sufficient to provide a component having a light transmissivity of at least 50% located between the light source and a polarizing film wherein said layered material comprises smectite clay or a layered double hydroxide.
