摘要： A radiation-sensitive composition includes a radically polymerizable component and an initiator composition capable of generating radicals sufficient to initiate polymerization of the radically polymerizable component upon exposure to imaging radiation. This composition also includes a radiation absorbing compound, a polymeric binder having poly(alkylene glycol) side chains, and a nonionic phosphate acrylate that has a molecular weight of at least 250. This composition can be used to prepare a negative-working imageable element that is sensitive to suitable imaging radiation and can be imaged at relatively low energy, developed either on-press or off-press, and then used for printing without a post-exposure baking step.

摘要： A method of preparing negative-working, single-layer imageable elements improves their storage stability in a humid environment. The method includes enclosing the coated imageable elements in a water-impermeable sheet material that substantially inhibits the transfer of moisture to and from the imageable element. Such imageable elements include a radiation-sensitive composition that includes a radically polymerizable component, an initiator composition to provide radicals upon exposure to imaging radiation, a radiation absorbing compound, and a polymeric binder having poly(alkylene glycol) side chains.

摘要： Negative-working imageable elements can be imaged and processed on-press to provide lithographic printing plates, especially with sulfuric acid-anodized aluminum substrates. These elements have an imageable layer that contains two different polymeric binders, a first polymeric binder that is present a discrete particles, and a second polymeric binder that comprises pendant ethylenically unsaturated groups.

摘要： The present invention provides an aqueous regenerator for addition to an aqueous developer that contains an organic solvent, a dispersing agent and a weak base, and has a pH of between about 8 and less than about 13. The aqueous regenerator includes an organic solvent, dispersing agent, and an effective amount of a strong base such that the regenerator has a greater pH than the developer into which the regenerator is to be added.
