The present invention relates to unique reflective polarized lenses that are anti-dazzling and reduce glare. In particular, it relates to polarized lenses utilizing a reflective polarizer, a high-transmission absorptive polarizer and photochromic treatment in a unique combination that can be injection molded to make thermoplastic ophthalmic lenses. The resulting lenses have high luminous transmission, high polarization efficiency for use in sunglasses and has potential applications for night vision

A method of producing an image on a final image receptor in a single pass electrophotographic system is provided. The method includes the steps of providing at least one toner development unit including a photoreceptive element and charged toner particles, and creating a toned image on the photoreceptive element that is transferred to an intermediate transfer member. The method further includes providing a transfer assist material development unit for applying a transfer assist material to at least a portion of the toned image to form a complete image layer on the intermediate transfer member, wherein the complete image layer is formed in a single pass of the intermediate transfer member. The method also includes contacting the complete image layer with a final image receptor while applying a bias that is sufficiently strong to transfer at least a portion of the complete image layer to the final image receptor.

A method of producing an image on a final image receptor from image data in a multiple pass electrophotographic system is provided. The method includes the steps of applying transfer assist material to an intermediate transfer member and providing at least one development unit including a photoreceptive element and charged toner particles. During each complete processing cycle of an intermediate transfer member, a toned image is created and transferred to the intermediate transfer member by application of a bias. In multiple processing cycles of the intermediate transfer member, the transfer assist material and the at least one toned image thereby form a composite image layer on the intermediate transfer member. The method further includes contacting the composite image layer with a final image receptor while applying a bias that is sufficiently strong to transfer at least a portion of the composite image layer to the final image receptor.

The present invention relates to methods of drying and recovering toner particles from a liquid carrier. The methods are very effective to generate discrete, substantially non-agglomerated dry toner particles in a manner that preserves the particle size and particle distribution of the wet particles. The resultant dried toner particles free-flowing with a relatively narrow particle size distribution. The present invention uses extrusion techniques to coat wet toner particles onto a substrate surface. Because the resultant coating has a relatively large drying surface area per gram of particle incorporated into the coating, drying may occur relatively quickly under moderate temperature and pressure conditions. After drying, the dried toner particles are readily recovered and may then be used in dry or even wet toners for electrophotographic applications.

The present invention uses electrical phenomena to help transfer charged toner particles from a liquid carrier onto a substrate surface. In practical effect, the particles are electrically plated onto the surface. Because the resultant coating has a relatively large drying surface area per gram of particle incorporated into the coating, drying may occur relatively quickly under moderate temperature and pressure conditions. After drying, the dried toner particles are readily recovered and may then be used in dry or even wet toners for electrophotographic applications.

A thermal transfer donor element is provided which comprises a support, a light-to-heat conversion layer, an interlayer, and a thermal transfer layer. When the above donor element is brought into contact with a receptor and imagewise irradiated, an image is obtained which is free from contamination by the light-to-heat conversion layer. The construction and process of this invention is useful in making colored images including applications such as color proofs and color filter elements.

摘要:
A rear projection screen assembly is described that includes a diffuser and a polarizer. The diffuser has particles dispersed within a binder. The particles and the binder have different refractive indices and are chosen such that the diffuser spreads light of an initial polarization state a cone of angles while substantially preserving the initial polarization state of the light. The diffuser also substantially depolarizing a portion of the light that is laterally scattered in the diffuser. The polarizer is disposed to receive light transmitted through the diffuser. The polarizer transmits light of the initial polarization state while absorbing a portion of the laterally scattered light that has a different polarization state. The resolution of the overall screen assembly may be made higher while also improving other characteristics of the screen assembly.
