    Abstract: Negative-working imageable elements have a hydrophilic substrate and a single thermally-sensitive imageable layer. This layer can include an infrared radiation absorbing compound and polymeric particles that coalesce upon thermal imaging. These coalesceable polymeric particles comprise a thermoplastic polymer and a colorant to provide improved visible contrast between exposed and non-exposed regions in the imaged element, such as lithographic printing plates.

    Abstract: An on-press ink and/or fountain solution developable lithographic printing plate comprising a photosensitive layer over an electrochemically grained, anodized, hydrophilically treated aluminum substrate with a reflection optical density of at least 0.30 is disclosed. The photosensitive layer is soluble or dispersible in ink and/or fountain solution and capable of hardening upon exposure to a laser having a wavelength of from 200 to 1200 nm. The plate is exposed with the laser off press or on press, and then on-press developed with ink and/or fountain solution. Such darker aluminum substrate in combination with the hydrophilic treatment allows fast press roll up, clean background, and good printing durability of the plate.
