Abstract: Lithographic printing plates having on a hydrophilic substrate an oleophilic photosensitive layer comprising an oleophilic polymer, a free radical polymerizable monomer, and 4-piperonyl-2,6-bis(trichloromethyl)-s-triazine as free radical initiator and/or leucomalachite green as exposure indicating dye; wherein the weight ratio of the monomer to the polymer is larger than 1.0. The plates can be developed with ink and/or fountain solution on a lithographic printing press or with a non-alkaline aqueous developer comprising 60-99% by weight of water and 0.5 to 40% by weight of an alcohol solvent. A photosensitive dye can be added in the photosensitive layer to provide photosensitivity to a specific wavelength between 200 and 1200 nm. Unlike commonly used s-triazine initiator or leuco dye, 4-piperonyl-2,6-bis(trichloromethyl)-s-triazine or leucomalachite green does not insolubilize from the photosensitive layer.
