A heat-sensitive negative-working lithographic printing plate precursor comprising;
- a support having a hydrophilic surface or which is provided with a hydrophilic layer and
- a coating provided thereon, said coating comprising an image-recording layer which comprises hydrophobic thermoplastic polymer particles, a binder and an infrared absorbing dye characterized in that;
- said hydrophobic thermoplastic polymer particles have an average particle diameter, measured by Photon Correlation Spectroscopy, of more than 10 nm and less than 40 nm and
- the amount of said IR-dye, without taking into account an optional counter ion, is more than 0.80 mg per m 2 of the total surface of said thermoplastic polymer particles, measured by Hydrodynamic Fractionation, and
- the amount of hydrophobic thermoplastic polymer particles relative to the total weight of the ingredients of the imaging layer is at least 60 %. |
