Abstract: The present invention relates to an infrared absorbing dye as defined in claim 1. The present invention relates also to a heat- sensitive imaging element comprising said IR dye and more particularly to a heat-sensitive lithographic printing plate precursor comprising said IR dye. The present invention relates also to a method for making a lithographic printing plate whereby a print-out image of high contrast is formed upon exposure to IR- radiation or heating.
