    摘要： Negative-working imageable elements have an imageable layer comprising a free radically polymerizable component, an initiator composition capable of generating radicals sufficient to initiate polymerization of the free radically polymerizable component upon exposure to imaging radiation, a radiation absorbing compound, one or more polymeric binders, and at least 5 weight % of core-shell particles comprising a hydrophobic polymeric core and a hydrophilic polymeric shell that is covalently bound to the polymeric core. The hydrophilic polymeric shell has one or more zwitterionic functional groups. These elements can be imaged such as by IR lasers to provide lithographic printing plates.

    摘要： The present invention provides a thermally sensitive composition that may be coated as a water-borne material onto a substrate to yield a printing plate precursor having an imageable coating. The thermally sensitive composition comprises a sulfated phenolic resin. The sulfated phenolic resin may be a sulfated novolak resin or a sulfated resole resin, for example. The thermally sensitive composition may include a water-soluble binder, such as polyvinyl pyrrolidone, and a radiation-absorbing component. The invention also provides a printing plate precursor that is developed in water after imaging. The precursor does not require chemical development with a developing solution containing organic solvents or inorganic additives. The imaged precursor is on-press-developable when used with a fountain solution. Methods for making and using the precursor are also provided.

    摘要： A concentrated developer can be prepared with less than 60 weight % water and still remain in a single phase with little or no haze or precipitation. This developer concentrate also includes a water-soluble or water-miscible organic solvent, one or more alkyl ether carboxylic acid, coconut oil alkanolamine, coconut fatty alcohol polyglycol ether, β-naphtholethoxylate, and block propylene oxide-ethylene oxide in an amount of at least 0.1 and up to 50 weight % solids, and optionally an alkyl naphthalene sulfonate in an amount of up to 40 weight % solids. The developer concentrate can be diluted up to 80:1 or greater with water and used to process imaged lithographic printing plate precursors.
