摘要： A lithographic printing plate is comprised of an anodized aluminum support having thereon an oleophilic image-forming layer comprising an infrared-absorbing agent dispersed in a film-forming cyanoacrylate polymer binder. The plate is imagewise exposed to a focused high-intensity infrared laser beam which removes the oleophilic image-forming layer by thermal ablation to thereby reveal the underlying hydrophilic support surface. The cyanoacrylate polymers provide superior performance due to their combination of low decomposition temperature, good ink receptivity, good adhesion to the support and good wear characteristics.

摘要： An assemblage for forming a lithographic printing plate is disclosed. The assemblage contains a receiver support with a rough hydrophilic surface; a layer containing a poly(cyanoacrylate) binder; and a donor support. When the assemblage is exposed with a high intensity laser beam, the binder is transferred to the hydrophilic surface of the receiver support to produce a lithographic printing plate. The transfer requires relatively low exposure and no post processing is necessary.

摘要： A process of forming a single color image comprising:a) imagewise exposing, by means of a laser, a dye-ablative recording element comprising a support having thereon, in order, a hydrophilic dye-receiving layer, a hydrophobic dye-barrier layer, and a hydrophilic, water-soluble, infrared-absorbing layer which absorbs at a given wavelength of the laser used to expose the element, thereby imagewise heating the infrared-absorbing layer and the dye-barrier layer, causing them to ablate;b) removing the ablated infrared-absorbing layer and dye-barrier layer material;c) contacting the imagewise-exposed element with an aqueous ink solution and thereby removing the remaining infrared-absorbing layer; andd) drying the element to obtain a single color image in the ablative recording element.

摘要： This invention relates to a process of forming a laser-induced thermal dye transfer image comprising:a) contacting at least one dye-donor element comprising a support having thereon a dye layer, having an infrared-absorbing material associated therewith, with a dye-receiving element comprising a support having thereon a polymeric dye image-receiving layer, said dye-donor and dye-receiver being separated by spacer beads;b) imagewise-heating the dye-color element by means of a laser at a given power supplied to the laser; andc) transferring a dye image to the dye-receiving element to form the laser-induced thermal dye transfer image,and wherein another portion of the dye-donor element or another dye-donor element is imagewise-heated by the laser to transfer a second dye image which is approximately the same hue as the first dye image and is in register with the first dye image to produce a given density, the power supplied to the laser for the first and second imagewise heatings being lower than the power which would have to be supplied to the laser to produce the same given density with only one imagewise heating.
