摘要 |
Provided are a photosensitive resin composition which enables production of a planographic printing plate precursor having a non-image portion which has good solubility in an alkali aqueous solution and which enables production of a planographic printing plate having excellent chemical resistance and excellent printing durability, a planographic printing plate precursor obtained by using the photosensitive resin composition, a method for producing a planographic printing plate, and a new polymer compound. The photosensitive resin composition of the present invention contains a polymer compound which has a polycyclic structure and a sulfonamide group in a main chain; and an infrared absorbent. |
