Abstract
Disclosed is a negative type lithographic printing plate material comprising a surface-roughened and anodically oxidized aluminum substrate and a photosensitive layer provided thereon, characterized in that: said photosensitive layer comprises a novolac resin, which contains a binder resin (a), a crosslinking agent (b), an infrared-absorbing agent (c) and an acid-generating agent (d), and in which the binder resin (a) contains 20-100 mass % inclusive of a phenol part expressed in ratio by mass, and a polyvinylphenol polymer; the content ratio of the novolac resin to the polyvinylphenol polymer (the mass of the novolac resin:the mass of the polyvinylphenol polymer) is 7:3 to 3:7; and the ratio by mass [(b)/(a)] is 0.25 to 0.50 inclusive. After the lithographic printing plate material is subjected to plate-making to give a lithographic printing plate, an image part thereof has a high solvent resistance and an excellent fraction resistance and the lithographic printing plate can be subjected to near infrared laser exposure.
