Abstract (en)
[origin: EP2236293A2] The present invention provides an infrared-sensitive positive-working photosensitive lithographic printing plate precursor that exhibits both an excellent chemical resistance in the image area and an excellent developability. This positive-working photosensitive lithographic printing plate precursor comprises a support having a hydrophilic surface, and a recording layer disposed on the support and comprising an alkali-soluble or alkali-swellable polymer having a structural unit represented by general formula (1) below, a novolac resin, an infrared absorber, and at least one member selected from aromatic group-containing sulfonium salts and iodonium salts wherein R 1 represents a hydrogen atom or methyl group, X represents a single bond, -COO-, or -CONH-, Ar 1 and Ar 2 each represent an optionally substituted aromatic group or heteroaromatic group, and Y represents - SO 2 NH- or -NHSO 2 -.
