Thermosensitive imaging element for the preparation of lithographic printing plates with improved transporting properties

摘要

The present invention provides an imaging element for making a lithographic printing plate comprising on a flexible support (i) an ink repellant layer containing a crosslinked hydrophilic binder and (ii) a thermosensitive layer comprising hydrophobic thermoplastic polymer particles dispersed in a hydrophilic binder, characterized in that an outermost layer is present on top of said imaging element on the opposite side of the support, said outermost layer comprising at least a solid or liquid lubricant in a hydrophilic binder.
