    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: 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.
