| 摘要 |
A photosensitive lithographic printing plate in which press life, deletion performance, photosensitive layer removability and image reproducibility are compatible with one another, while retaining scumming prevention performance, which comprises an aluminum support hydrophilized after anodic oxidization, an intermediate layer provided thereon containing an alkali-soluble polymer adjusted in a number-average molecular weight (Mn) to the range of 300 to 5,000 by using an initiator in combination with a chain transfer agent in radical polymerization, and a photosensitive layer provided on the intermediate layer.
