<P>PROBLEM TO BE SOLVED: To provide a lithographic printing plate material which is free from the scumming of a non-image part, i.e. greasing, and has successful proofness to a printing failure caused by the microdot-like scumming of the non-image part in an early printing stage, dust deposition, etc., a lithographic printing plate, a method for manufacturing the lithographic printing plate and a method for printing the lithographic printing plate. <P>SOLUTION: This lithographic printing plate material has an undercoat layer containing a chemical compound represented by a formula (1) and an imaging function layer containing a photothermal conversion material, a photopolymerizable compound and a polymerization initiating material formed on an aluminum base. The imaging function layer can have the non-image part removed by supplying a printing ink of an oxidative polymerization type which is free from skinning after leaving at rest for 12 hours in an environment at 30°C and 50% RH (relative humidity). <P>COPYRIGHT: (C)2007,JPO&INPIT |
