Abstract:
A method for the manufacture of a matrix on a substrate, said matrix being particularly useful in the formation of color filter elements, the process comprising the steps of:a) providing an imageable article comprising a substrate having on at least one surface thereof a black layer,b) directing energy of sufficient intensity at said black layer to transparentize black layer,c) said directing of energy being done so that black layer is removed in some areas, but is not removed in other areas so that borders of black layer surround areas from which black layer has been removed.A preferred method deposits colorant material within the open areas of the matrix by thermal transfer, e.g., laser induced thermal transfer, of colorant material to form a filter element.

A thermal mass transfer imaging process comprises the thermal mass transfer of a white or metallic donor layer which is then at least partially over-coated with a thermally transferred dye image.

Abstract:
This invention relates to a laser imageable donor material that is capable of transferring pigment to a receiver, such as plain paper, polymeric film, metal and the like. The donor material is composed of at least a transparent film, an overlying layer of vapor coated black aluminum, and a dye coating or pigment coating dispersed on top of the black aluminum. A material which generates gas when irradiated may also be present as a separate layer under or in the dye or pigment layer and above the black aluminum layer. The construction can be addressed with diode lasers and diode-pumped solid state lasers.The invention can be used to produce large format digital halftone color proofs using high power air-cooled diode-pumped Nd:YAG and Nd:YLF lasers. Other materials could be transferred from the donor sheet in this process as well as the colorant (dye or pigment) layer.
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:
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.
