    Abstract: A lithographic printing plate precursor is disclosed, comprising a hydrophilic support having thereon a heat-sensitive layer containing either a microcapsule containing a compound having a functional group capable of reacting by heat or a fine particulate polymer, wherein (1) when the heat-sensitive layer contains a fine particulate polymer, the fine particulate polymer may be a fine particulate polymer capable of combining or incapable of combining by heat used for the image formation and the fine particulate polymer has a functional group capable of reacting with a functional group present in another fine particulate polymer or with a functional group present in another component in the heat-sensitive layer; or (2) when the heat-sensitive layer contains a microcapsule containing a compound having a functional group capable of reacting by heat, the microcapsule may be a microcapsule having an outer wall capable of rupturing or incapable of rupturing by heat used for the image formation and a light-to-heat converting material is contained in the heat-sensitive layer or in a layer adjacent thereto.

    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.

    Abstract: This patent describes an on-press developable thermosensitive lithographic plate having on a substrate a thermosensitive layer comprising an ethylenically unsaturated monomer, an infrared absorbing dye, and an onium or borate salt free radical initiator. The plate can be imagewise exposed with an infrared laser on a plate exposure device, and then mounted on a lithographic press for on-press development with ink and/or fountain solution and lithographic printing. No regular development process with a liquid developer is needed after exposure. Alternatively, the plate can be imagewise exposed with an infrared laser while mounted on a plate cylinder of a lithographic press, on-press developed with ink and/or fountain solution, and then print images to the receiving sheets.
