摘要:
This invention relates to a dye donor element for laser-induced thermal dye transfer comprising a support having thereon a dye layer comprising an image dye in a binder and an infrared-absorbing material associated therewith, and wherein the infrared-absorbing material is a telluro- or seleno-squarylium dye having the following formula: ##STR1## wherein: R.sub.1, R.sub.2, R.sub.3 and R.sub.4 each independently represents hydrogen or a substituted or unsubstituted alkyl, aryl or hetaryl group;R.sub.5 and R.sub.6 each independently represents hydrogen, halogen, cyano, alkoxy, aryloxy, acyloxy, aryloxycarbonyl, alkoxycarbonyl, sulfonyl, carbamoyl, acyl, acylamido, alkylamino, arylamino, or a substituted or unsubstituted alkyl, aryl or hetaryl group;X represents Se or Te; andY represents O, S, Se, Te, TeCl.sub.2 or TeBr.sub.2, with the proviso that when X and Y are both Se and R.sub.1, R.sub.2, R.sub.3 and R.sub.4 each represents t-butyl, then R.sub.5 and R.sub.6 cannot both be hydrogen at the same time; and with the second proviso that when X is Se and Y is O and R.sub.1, R.sub.2, R.sub.3 and R.sub.4 each represents t-butyl, then R.sub.5 and R.sub.6 cannot both be hydrogen at the same time.

A system for engraving a flexographic relief member includes a laser scanning apparatus providing a focused radiation beam. The flexographic relief member includes a laser engravable flexographic member; a thing engravable control layer on top of the flexographic member; and wherein the engravable control layer has an engraving sensitivity lower than the flexographic member.
摘要:
Preparing a flexographic member (60) includes providing a digital image and calculating a relief image based on the digital image. At least one stress-sensitive boundary region (11) adjacent to at least one image feature is identified and the relief image is created on the flexographic member. The depth (18) of at least a portion of a floor region (10) adjacent the at least one image feature is increased to provide a modified floor region.

A method for making an organic electroluminescent display device having an array of pixels disposed on a display substrate includes providing a donor element and a display substrate that are heated to a desired temperature. Radiation-induced thermal transfer is then used to transfer organic material from the donor element to the display substrate.

This invention relates to a single-sheet process for obtaining a multicolor image comprising:a) coating a support with a polymeric adhesion layer;b) coating the adhesion layer with a single dye layer comprising a mixture of at least two different colors of solid, homogeneous beads, each of which contains an image dye, a binder and a laser light-absorbing material, the beads being dispersed in a vehicle, and the beads of each color being sensitized to a different wavelength;c) exposing the element to laser light at the wavelength to which each type of bead is sensitized, causing the exposed beads to melt and become adhered to the polymeric adhesion layer; andd) removing any unadhered beads.

A system for engraving a flexographic relief member includes a laser scanning apparatus providing a focused radiation beam. The flexographic relief member includes a laser engraveable flexographic member; a thin engraveable control layer on top of the flexographic member; and wherein the engraveable control layer has an engraving sensitivity lower than the flexographic member.

摘要:
A method for producing a patterned material for electronic or photonic circuits, comprising the steps of:p) providing a substrate;q) coating the substrate with a polymer layer;r) coating a thermal resist solution over the polymer layer to form a thermal resist layer, wherein the polymer layer is substantially immiscible in the thermal resist solution;s) exposing predetermined areas of the thermal resist layer, corresponding to a desired image pattern, using infrared light;t) removing portions of the thermal resist layer corresponding to a desired image pattern, using a developer;u) removing the polymer layer where the thermal resist layer has been previously removed and undercutting a portion of the remaining thermal resist layer by an etching process;v) depositing a material using a substantially anisotropic process; and removing the remaining thermal resist layer and any overlying material with a solvent for the polymer or thermal resist layers leaving the material in a desired pattern.
