Precursor for direct printing-type waterless lithographic printing plate and method for producing same

摘要

Provided is a precursor for a direct printing-type waterless lithographic printing plate which shows high sensitivity not only immediately after the production of the precursor but also after the passage of time. A precursor for a direct printing-type waterless lithographic printing plate, which at least comprises a heat-sensitive layer and a silicone rubber layer that are laminated on a substrate in this order, wherein said heat-sensitive layer comprises a liquid foam which contains a liquid having a boiling point within a range of 210-270
