Abstract
A positive-type planographic printing original plate for direct plate-making with an infrared laser, with excellent latitude in forming an image by development, and excellent flaw resistance. The planographic printing original plate includes, on a support, a positive-type recording layer whose solubility with respect to an alkaline aqueous solution is increased by infrared laser exposure. The recording layer contains an alkali-soluble resin, which has a fluorine atom in the molecule, and an infrared absorbing agent. The alkali-soluble resin can be provided by introducing at least one substituent having a fluorine atom to a known alkali-soluble polymer compound.
