| abstract |
By a lithographic printing plate precursor comprising a support having provided thereon an image-recording layer containing (A) a radical polymerization initiator, (B) a radical polymerizable compound, and (C) a polyfunctional polymerization inhibitor, wherein the polyfunctional polymerization inhibitor has, in a molecule thereof, two or more radical trapping sites to form a covalent bond by directly connecting with a radical, a lithographic printing plate precursor which is capable of being directly recorded from digital data, for example, of a computer, which has high sensitivity, and which can form an image having a high image quality by preventing an undesirable curing reaction in the non-image area from proceeding, wherein the lithographic printing plate precursor can provide a lithographic printing plate having high printing durability, and a plate making method using the same are provided. |
