摘要： 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.

摘要： 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 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 imageable layers provides a reduced tendency of these dyes to crystallize in the presence of tetraaryl borate counter anions.

摘要： Lithographic printing plates are prepared by imaging and developing negative-working lithographic printing plate precursors that include certain particulate polymeric binders in the photosensitive imageable layer. Such particulate polymeric binders are poly(urethane-acrylic) hybrids. Development is carried out using a working strength developer that includes one or more organic solvents in a total amount of at least 7 weight % and an anionic surfactant in an amount of at least 5 weight %.

摘要： 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.

摘要： 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.
