A multilayer optical film has a packet of microlayers that selectively reflect light by constructive or destructive interference to provide a first reflective characteristic. At least some of the microlayers are birefringent. A stabilizing layer attaches to and covers the microlayer packet proximate an outer exposed surface of the film. Heating element(s) can physically contact the film to deliver heat to the packet through the stabilizing layer by thermal conduction, at altered region(s) of the film, such that the first reflective characteristic changes to an altered reflective characteristic in the altered region(s) to pattern the film. The stabilizing layer provides sufficient heat conduction to allow heat from the heating elements to change (e.g. reduce) the birefringence of the birefringent microlayers disposed near the outer exposed surface in the altered region(s), while providing sufficient mechanical support to avoid substantial layer distortion of the microlayers near the outer exposed surface in the altered region(s).

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.

An adhesive composition that includes the reaction product of (a) a polyester-based polyurethane; (b) an epoxy resin; (c) an epoxy-functional silane; and (d) an isocyanate-functional compound, and multilayer laminates in which this adhesive composition is used to bond two polymeric substrates together where at least one of the substrates has an ink-bearing surface.

Disclosed is a protective cover package for an endless, organic photoreceptor belt of an electrophotographic printer. The protective cover package is a flexible, closed loop sheet member which extends about an outer, photoreceptor coated surface of the endless belt. The photoreceptor coated surface of the endless belt is releasably secured to an inner surface of the sheet member, such that the sheet member supports the belt, and protects the photoreceptor surface from damage that would adversely affect the image reproduction quality of the belt. The sheet member has a belt loading configuration, that substantially duplicates the configuration of the endless belt when the belt is mounted onto support rollers of the electrophotographic printer. By replicating the configuration of the support rollers, loading of the belt onto the rollers is facilitated using the protective cover package. The sheet member also has a compact configuration that requires less volume than the belt loading configuration. The compact configuration of the sheet member minimizes shipping volume and storage space requirements for replacement photoreceptor belts.

A process is described for forming an emissive or phosphor screen. The process comprises the steps of: a) providing a thermal mass donor element comprising a substrate with a front side and a back side, with a coating of emissive material or phosphor adhered to said front side of said substrate, b) placing said coating of emissive material or phosphor adjacent to a support layer, c) addressing said mass donor element with coherent radiation to heat at least a portion of said coating of emissive material or phosphor to locally transfer at least some of said emissive material or phosphor to said support layer, d) repeating step c) a sufficient number of times to provide a coating of transferred emissive material or phosphor on said support layer in an area of at least 1 square centimeter.
