Abstract: Negative-working imageable elements that can be imaged using infrared radiation comprise an imageable layer and a protective overcoat on a hydrophilic substrate. The imageable layer includes an IR-sensitive cyanine dye. The protective overcoat predominantly comprises one or more poly(vinyl alcohol) resins, each of which has a hydrolysis level of 85% or less. The use of this particular overcoat composition used in combination with the IR-sensitive cyanine dye provides improved tolerance to fogging by white light while maintaining desired imaging speed.

Abstract: The present invention relates to negative-working imageable elements that can be used for the manufacture of printing plates. These imageable elements can be developed on on-press by the action of a lithographic printing ink used in combination with either water or a fountain solution. The imageable elements comprise an imageable layer that is not removable in water or fountain solution alone. The imageable layer includes a free radically polymerizable compound, a free radical initiator composition, an infrared radiation absorbing compound, and a polymeric binder comprising poly(alkylene oxide) pendant groups, and preferably additionally pendant cyano groups.
