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, an infrared light absorbing dye and a dye, characterized in that said dye has a specified structure and a most bathochromic light absorption peak between 451 nm and 750 nm.
