Abstract: Negative thermosensitive lithographic printing plates developable with a non-alkaline aqueous developer and method of developing such plates. The plate comprises on a substrate a thermosensitive layer comprising an ethylenically unsaturated monomer, a free radical initiator, and an infrared absorbing dye. The plate can be imagewise exposed with an infrared laser to cause hardening in the exposed areas and then developed with a non-alkaline aqueous developer to remove the non-exposed areas. The non-alkaline aqueous developer can be water or an aqueous solution comprising at least 60% of water and having a pH of 2.0 to 10.0.
