摘要:
A lithographic printing process which comprises the steps of: imagewise scanning with a laser a presensitized lithographic plate which comprises a hydrophilic support and an image-recording layer containing a polymerization initiator, an ethylenically unsaturated polymerizable compound having no adherence to the hydrophilic support, and an ethylenically unsaturated polymerizable compound having adherence to the hydrophilic support and a molecular structure comprising a polyoxyalkylene group to polymerize the ethylenically unsaturated polymerizable compounds within the exposed area; removing the image-recording layer within the unexposed area from the lithographic plate mounted on a cylinder of a printing press; and then printing an image with the lithographic plate mounted on the cylinder of the printing press. A presensitized lithographic plate is also disclosed.
