    Abstract: A negative image-recording material for heat-mode exposure, which is able to form images by heat-mode exposure, comprises (A) a polyurethane resin having at least one or more side-chain branches of the following general formulae (1) to (3) which polyurethane resin is soluble in an alkaline aqueous solution, (B) a photo-thermal converting agent, and (C) a compound capable of generating a radical through heat-mode exposure to light of a wavelength which can be absorbed by the photo-thermal converting agent. In formulae (1) to (3), R1 to R11 each independently represents a monovalent organic group; X and Y each independently represents an oxygen atom, a sulfur atom, or nullN(R12)null; Z represents an oxygen atom, a sulfur atom, nullN(R13)null, or an optionally-substituted phenylene group; R12 represents a hydrogen atom or a monovalent organic group; and R13 represents a hydrogen atom or a monovalent organic group. 1

    Abstract: This patent describes an on-press ink and/or fountain solution developable lithographic printing plates having on a substrate a thermosensitive layer capable of hardening upon exposure to an infrared radiation. The plate can be imagewise exposed with an infrared radiation and then on-press developed with ink and/or fountain solution by rotating the plate cylinder and engaging ink and/or fountain solution roller. The developed plate can then directly print images to the receiving sheets. The imagewise exposure can be performed off the press or with the plate being mounted on the plate cylinder of a lithographic press.

    Abstract: Lithographic imaging using non-ablative printing members combines the benefits of simple construction, the ability to utilize traditional metal base supports, and amenability to imaging with low-power lasers that need not impart ablation-inducing energy levels. A representative printing member has a hydrophilic metal substrate and, thereover, first and second layers. The first layer has a thickness and an exposure surface and comprises a material that absorbs imaging radiation. The second layer overlies the first layer and is oleophilic and substantially transparent to imaging radiation. Exposure to imaging radiation causes the first layer and the substrate to irreversibly detach without substantial ablation, thereby facilitating removal, by subjection to the cleaning liquid, of the first and second layers where detachment has taken place.

    Abstract translation: 使用非烧蚀印刷部件的平版印刷成像结合了简单结构的优点，利用传统金属基底支架的能力，以及使用不需要赋予消融诱导能量水平的低功率激光器成像的优点。 代表性的印刷部件具有亲水性金属基板，并且具有第一和第二层。 第一层具有厚度和曝光表面，并且包括吸收成像辐射的材料。 第二层覆盖第一层，并且是亲油的并且对成像辐射基本上是透明的。 暴露于成像辐射会导致第一层和衬底不可逆地分离而无需实质的消融，从而有助于通过置于清洁液体上去除已发生分离的第一层和第二层。
