Negative working, heat-sensitive lithographic printing plate precursor

摘要

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
- an image-recording layer comprising hydrophobic thermoplastic polymer particles and an infrared light absorbing dye;
characterized in that:
- said image-recording layer further comprises a compound, said compound comprising an aromatic moiety and at least one acidic group or salt thereof and having a most bathochromic light absorption peak at a wavelength between 300 nm and 450 nm.
