<P>PROBLEM TO BE SOLVED: To provide a photosensitive lithographic printing plate precursor for infrared laser which exhibits excellent chemical and scratch resistances of an image area, has good developability, and improves printing durability when heat-treated at a high temperature after development. <P>SOLUTION: The photosensitive lithographic printing plate precursor includes in the following order: a support having a hydrophilic surface; a lower layer containing a polymer compound having a unit derived from a (meth)acrylic acid derivative monomer of a specific structure, a polymer compound having an aminomethyl structure-containing group in a side chain, and an infrared absorbent; and an upper layer containing a water-insoluble and alkali-soluble resin. <P>COPYRIGHT: (C)2010,JPO&INPIT |
