Abstract:
A thermal imaging transfer process and donor sheet are described. The donor sheet comprises a layer of particulate colorant/binder on a substrate. Essentially individual particles are transferred during imaging to provide a high resolution image.
Abstract:
A liquid developer imaging system comprising a developing container for receiving a quantity of developing solution, a sensing system for maintaining a predetermined processing level of developing solution within the container, a developer roller connected to a first power supply source that biases the developer roller to a development voltage, and a skiving element for plating the developing solution onto the developer roller and scraping excess developing solution from the developer roller to a predetermined thickness, wherein the skiving element is connected to a second power supply source for biasing the skiving element to a skiving voltage, wherein the skiving voltage is greater than the development voltage.
Abstract:
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.
Abstract:
The present invention describes a process for the formation of a black image on a substrate comprising the steps of:a) providing a donor element comprising a carrier substrate, a black, pigmented photohardenable layer, and photopolymerizable adhesive layer in which the unexposed photopolymerizable adhesive layer has a viscosity at 25.degree. C. of less than 100,000 cps,b) adhering said photopolymer adhesive layer to a first substrate,c) irradiating said photopolymer adhesive in an imagewise distribution of radiation to polymerize said adhesive in an imagewise distribution, andd) stripping said element from said first substrate leaving an imagewise distribution of said black pigmented layer secured to said substrate.The black image formed on a substrate by the present invention comprises a substrate, an imagewise distribution of areas of cured photopolymerizable adhesive with a layer of black pigmented polymer over each area of cured photopolymer adhesive, and uncured photopolymerizable adhesive having no black pigmented material on its surface on said substrate between areas of black pigmented polymer. This process is especially useful in the formation of black matrices for color filter elements.

Abstract:
This invention provides a composite article comprising a support member, a controlled release material coated on the support member, and an inorganic pigment coated onto the controlled release material. In another aspect, this invention provides a method of making the same. The controlled release material comprises a first component and optionally a second component which are independently one of an organic material and an inorganic material. The composite article, which can be a donor substrate, is useful in thermal imaging.
Abstract:
An electrographic imaging process is described in which electrostatic images are toned in sequence to form a multicolor intermediate image on a temporary dielectric receptor. The intermediate image is then transferred to a permanent receptor. Certain relative properties of the toner and the intermediate image, such as surface energy, T.sub.g, work of adhesion, and complex dynamic viscosity, have been found to be important to the production of good final images.
Abstract:
An article having a primed surface or improved electric charge transfer properties is disclosed. The surface has discrete sites of inorganic materials thereon.
Abstract:
Imaging processes where charge images are transferred from one surface to another are improved by the presence of conductivity sites on at least one of the surfaces, said sites being discrete, composed of an inorganic material, and having an average length between 1.0 and 20 nm. Between 0.1 and 40% of either the photoconductive surface or dielectric layer may be covered with electrically conductive sites.
