<p>A thermally convertible lithographic printing precursor comprises a lithographic base with an imageable coating. The imageable medium of the coating comprises uncoalesced particles of a hydrophobic thermoplastic polymer, a converter substance capable of converting radiation into heat, and a metal complex. A lithographic printing master is made by image-wise or information-wise exposing the precursor to radiation and then developing the precursor with an aqueous medium to remove the unirradiated parts of the coating.</p> |
