    Abstract: Positive-working imageable elements can be used to prepare lithographic printing plates. These elements have at least two layers (inner and outer) arranged on a suitable substrate. The inner layer that is closer to the substrate includes one or more polymeric binders that include pendant oxazoline groups and acid groups that are reactive with the oxazoline groups during a post-baking step after development. The resulting imageable elements are more quickly baked in this manner to provide improved run length and resistant to press chemicals.

    Abstract: An imaged and developed element, such as a lithographic printing plate, is provided by infrared radiation imaging of a negative-working imageable element having an outermost imageable layer that includes an acid generating compound that generates acid upon exposure to imaging infrared radiation, an infrared radiation absorbing compound, an acid activatable crosslinking agent that has acid activatable reactive groups, and a polymeric binder that is capable of undergoing an acid-catalyzed condensation reaction with the crosslinking agent. The imaged element is heated at from about 120 to about 150° C. for up to two minutes, and then developed with a single processing solution to remove only the non-exposed regions and to provide a protective layer prior to lithographic printing.
