Abstract: Images can be provided using a method comprising thermally imaging a negative-working imageable element to provide an imaged element with exposed regions and non-exposed regions, the exposed regions consisting essentially of coalesced core-shell particles, and developing the imaged element on-press to remove only the non-exposed regions using a lithographic printing ink, fountain solution, or both. The imageable element comprises a single thermally-sensitive imageable layer consisting essentially of an infrared radiation absorbing compound and core-shell particles that coalesce upon thermal imaging. The core of the core-shell particles is composed of a hydrophobic thermoplastic polymer, the shell of the core-shell particles is composed of a hydrophilic polymer that is covalently bonded to the core hydrophobic thermoplastic polymer, and the thermally-sensitive imageable layer comprises less than 10 weight % of free polymer.

Abstract: Lithographic printing plates can be provided by imagewise exposing a negative-working lithographic printing plate precursor comprising an aluminum-containing substrate having thereon an imageable layer, to provide exposed and non-exposed regions in the imageable layer. This imaged element is then processed to remove the non-exposed regions in the imageable layer and to gum the resulting image in a single step without an intermediate rinsing step by using an aqueous alkaline solution having a pH of at least 9. The aqueous alkaline solution includes an organic amine having a boiling point of less than 300° C., a film-forming hydrophilic polymer, and optionally an anionic or nonionic surfactant.

Abstract: A lithographic printing plate precursor comprises an imageable layer comprising a free radically polymerizable component, an initiator composition capable of generating free radicals upon exposure to imaging infrared radiation, an infrared radiation absorbing dye that is defined by Structure (I) shown in the disclosure, which dyes comprise one or more ethylenically unsaturated polymerizable groups in an organic group that is attached to the methine chain. These infrared radiation absorbing dyes exhibit a reduced tendency to crystallize in the imageable layers in the presence of tetraaryl borate counter anions and therefore provide improved shelf life.

Abstract: Imaged lithographic printing plates are processed using a developer that is replenished with only water, but replenishment is at a rate to allow developer volume to slowly decrease from a developer reservoir. This allows for a longer processing cycle especially when the developer is supplied from a container having a defined amount and applied using spray devices where water evaporation from the developer can be significant. Water lost by evaporation is replenished while water carried out by lithographic printing plates is not replenished.
Abstract translation: 使用仅补充水的显影剂对成像的平版印刷版进行处理，但补充量使得显影剂体积从显影剂储存器缓慢降低。 这特别是当显影剂从具有限定量的容器供应并且使用喷雾装置施加显影剂时，可以延长处理周期，其中来自显影剂的水蒸发可能是显着的。 补充水蒸气损失的水分，而平版印刷版的水不补充。

Abstract: A lithographic printing plate precursor comprises an imagable layer comprising a free radically polymerizable component, an initiator composition capable of generating free radicals upon exposure to imaging infrared radiation, an infrared radiation absorbing dye comprising an infrared radiation absorbing cation and a counter anion, and a polymeric binder. The salt formed between the infrared radiation absorbing cation and a tetraphenyl borate has solubility in 2-methoxy propanol at 20° C. that is greater than or equal to 3.5 g/l. The use of these infrared radiation absorbing dyes in the imagable layers provides a reduced tendency of these dyes to crystallize in the presence of tetraaryl borate counter anions.

Abstract: Imageable elements can be imaged and then processed using a solution containing core-shell particles that are designed to complex with non-coalesced particles in the non-exposed regions of imaged element. A separate development step is not needed, but the non-coalesced particles and complexed core-shell particles can be removed from the resulting printing plate before using the resulting lithographic printing plate for printing.
