Abstract
A presensitized planographic printing plate which can be used in both negative and positive work comprising a support, a layer formed on the support of a photosensitive substance prepared by the reaction at a pH of not more than 7.5 of a diazonium compound with a coupling agent, e.g., hydroxybenzophenone, and a layer formed on the photosensitive layer of a 'one-package' silicone rubber curable at room temperature. A planographic printing plate per se is produced by imagewise exposing the presensitized plate through a negative or positive film, and treating the exposed plate with a treating liquid capable of removing those portions of the presensitized plate which correspond to the image area of the original. Dampening water is not required when printing is carried out using the resulting printing plate.
