    摘要： A negative-working imageable element has an imageable layer that includes an infrared radiation absorbing dye that upon exposure to thermal irradiation, changes from colorless to a visible color or from one visible color to another visible color, providing a ΔE of at least 5 between the exposed and non-exposed regions of the imageable layer within 3 hours of its exposure to 300 mJ/cm2 at a laser power of 15 Watts. The imageable element can be imaged to provide images with improved contrast for print-out. The imageable layer includes a primary polymeric binder that has a backbone to which are attached pendant poly(alkylene oxide) side chains, cyano groups, or both, and is optionally present in the form of discrete particles.

    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.

    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.
