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： Lithographic printing plate precursors have been designed so that they can be stored, shipped, and used in stacks without interleaf paper between individual precursors. This is achieved by incorporating polymeric particles having an average diameter of from about 3 to about 20 μm into the outermost precursor layer such as an imageable layer or topcoat. The polymeric particles comprise a core of a crosslinked polymer and have grafted hydrophilic polymeric surface groups that are grafted onto the particle surfaces by polymerizing hydrophilic monomers in the presence of the crosslinked polymeric particles. The lithographic printing plates can be either negative- or positive-working elements.
