    Abstract: Negative thermosensitive lithographic printing plates comprise on a hydrophilic substrate an oleophilic thermosensitive layer comprising a polymeric binder, urethane (meth)acrylate monomer having at least 6 (meth)acrylate groups, a non-urethane (meth)acrylate monomer having at least 4 (meth)acrylate groups, a free-radical initiator, and an infrared absorbing dye; wherein the weight ratio of said urethane (meth)acrylate monomer to said non-urethane (meth)acrylate monomer is from 0.10 to 3.0, and said thermosensitive layer is capable of hardening upon exposure to an infrared radiation. Lithographic plates with such compositions have excellent press durability.

    Abstract: The present invention relates to a method for forming images which comprises imagewise exposing a photopolymerizable image-forming material comprising a substrate provided thereon with an image-recording layer which comprises a specific photopolymerization initiator system, a polymerizable compound carrying at least one ethylenically unsaturated group and a binder polymer and then developing the imagewise exposed material with a developer containing at least one carbonate and at least one hydrogen carbonate and a specific surfactant in an amount ranging from 1.0 to 10% by weight, and having a specific pH and a specific electrical conductivity. The image-forming method permits the achievement of a sufficient developing ability even at a relatively low pH at which the image-forming material is not damaged so much and the preparation of a printing plate having good printing durability.

    Abstract: A method of making a lithographic printing plate is disclosed which comprises the steps of (1) providing a lithographic printing plate precursor comprising (i) a support having a hydrophilic surface or which is provided with a hydrophilic layer and (ii) a coating provided thereon which comprises hydrophobic thermoplastic polymer particles; (2) exposing the precursor to IR-light or heat, thereby inducing coalescence of the thermoplastic polymer particles at exposed areas of the coating; (3) applying a hydrophilic protective layer on the coating; and then, (4) while the precursor is mounted on a print cylinder of a printing press, developing the precursor by supplying an aqueous dampening liquid and/or ink to said precursor while rotating said print cylinder whereby the coating and the hydrophilic protective layer are removed from the support on the non-exposed areas. According to the above method, the hydrophilic protective layer can be applied by coating a solution by means a spray nozzle or a jet nozzle and wherein the applied hydrophilic protective layer improves clean-out in an on-press development.
