摘要:
A liquid crystal dispersion display including an opaque first conductive layer including developed silver crystals and having a plurality of first openings for transmission of light; a water permeable coated layer having dispersed liquid crystals in a binder over the opaque first conductive layer; an opaque second conductive layer including developed silver crystals coated over and coextensive with portions of the opaque first conductive layer and formed with second openings which are offset from the first openings; and a structure for changing the electrical potential between the first and second conductive layers so as to effect a change in the dispersed liquid crystals which in a first state causes light which passes through the first openings to be absorbed by the second conductive layer and in a second state which causes light to be scattered and passed out through the second openings in the display.
摘要:
An imaging member can be prepared by imagewise application of a mixture of a sol precursor in a liquid to a suitable substrate. Application is preferably accomplished by ink jet printing. Upon removal of the liquid, such as by drying, an insoluble, crosslinked polymeric sol-gel matrix is formed that will accept a lithographic printing ink. The resulting imaging member can be used for lithographic printing.
摘要:
A method for transferring colorant from a donor element to a compact disc (CD) includes holding a CD in the focal plane of a focused laser beam with a colorant donor element being positioned in transferable relationship with the CD and focusing a laser beam on the colorant donor element to heat the donor element to a sufficient temperature to transfer colorant to the CD to thereby effect the transfer of colorant from the donor element to the CD.

摘要:
A process is described for producing a direct digital, halftone color proof of an original image on a dye-receiving element, the proof being used to represent a printed color image obtained from a printing press, comprising:a) generating a set of electrical signals which is representative of the shape and color scale of an original image;b) contacting a dye-donor element comprising a support having thereon a dye layer and an infrared-absorbing material with a first dye-receiving element comprising a support having thereon a polymeric, dye image-receiving layer;c) using the signals to imagewise-heat by means of a diode laser the dye-donor element, thereby transferring a dye image to the first dye-receiving element; andd) retransferring the dye image to a second dye image-receiving element which has the same substrate as the printed color image.
摘要:
A process for forming a color image which may be used to represent a printed color image to be obtained from a printing press comprising (a) forming a thermal dye transfer image in a polymeric dye image-receiving layer of an intermediate dye-receiving element by imagewise-heating a dye-donor element and transferring a dye image to the dye image-receiving layer, (b) applying a dye-migration barrier layer to one surface of a paper substrate, and (c) transferring the imaged polymeric dye image-receiving layer to the surface of the paper having the dye-migration barrier layer applied thereon. By first applying a dye-migration barrier layer to the paper substrate, dye smear and spreading due to migration of dye into the paper can be eliminated and a high quality final color image can be obtained.
