    摘要： Embodiments of the present invention involve printing members that utilize a particle-fusion imaging mechanism but avoid susceptibility to handling damage. In particular, printing plates in accordance with the invention may utilize two phases, and these may originate, during manufacture, as two particle systems. Both systems are initially dispersed in a single coating applied as a layer, or in multiple coatings applied as adjacent layers, on a substrate. The second particle system exhibits a glass-transition or thermal coalescing temperature well above room temperature and also above the temperature at which the coating is dried. The coalescing temperature of the first particle system is below the drying temperature. As a result, when the coating is dried, the first particle system coalesces and forms a binder that entrains the second particle system, which has not coalesced. The binder formed by the first particle system is preferably insoluble in aqueous liquids, but is swellable or softened by such liquids, whereas the binder formed by the second particle system is preferably insoluble in and not swellable by aqueous liquids. Aqueous insolubility allows the dried (and ready-to-image) coating to resist handling damage, while swellability facilitates development.

    摘要翻译： 本发明的实施例涉及使用粒子 - 融合成像机构的打印构件，但是避免了对处理损伤的敏感性。 特别地，根据本发明的印版可以利用两个阶段，并且这些可以在制造期间作为两个粒子系统产生。 两种体系最初分散在单层涂层中，作为一层施加，或者在作为相邻层施加的多层涂层中分散在基底上。 第二颗粒体系表现出远高于室温的玻璃化转变或热聚结温度，并且还高于涂层干燥的温度。 第一颗粒系统的聚结温度低于干燥温度。 结果，当涂层干燥时，第一颗粒系统聚结并形成夹带未结合的第二颗粒体系的粘合剂。 由第一粒子系统形成的粘合剂优选不溶于水性液体，但是由这种液体可膨胀或软化，而由第二粒子体系形成的粘合剂优选不溶于水性液体并且不能溶胀。 水不溶性允许干燥（和准备成像）涂层抵抗处理损伤，而溶胀性促进了发展。

    摘要： Gum solutions are formulated to develop a negative-working photopolymer imaging layer coated on an anodized aluminum substrate that has undergone a post-anodic sealing treatment with inorganic phosphate and inorganic fluoride. The gum solution contains at least one polycarboxylic acid—which may be a polymer—that beneficially desensitizes the surface after the unexposed photopolymer layer is removed.

    摘要： Thermally imageable elements comprising a masking layer and a substrate are disclosed. The masking layer contains a sulfobetaine and/or a carboxybetaine containing co-polymer or a mixture of a sulfobetaine and/or a carboxybetaine containing co-polymers and absorbs both infrared and ultraviolet radiation. When the masking layer is on the substrate, the imageable element may be imaged and developed to form a photomask. When the imageable element additionally comprises a photosensitive layer, the masking layer may be imaged and developed to form an integral photomask. The imageable elements that comprise a photosensitive layer are useful as flexographic printing plate precursors.
