From EP 0770495 A1 known offset printing plate, comprising absorbing materials in the near infrared region, a polymeric binder and thermoplastic particles, capable of connection when heated. From U.S. patent 6983694 known continuously show negative offset printing plates, covered with coating compounds that are sensitive to near infrared region comprising thermoplastic polymer particles such as polystyrene or the and(Acrylonitrile-co-styrene) particles, not reactive hydrophilic polymer binder and dyes that absorb infrared radiation.

In addition, U.S. patent No. 6261740 known negative offset printing plates, covered with coating compounds that are sensitive in the near infrared region, including methoxyethylamine copolymers, phenolic resins, salts iodine and dyes that absorb in the near infrared region. From U.S. patent No. 6124425 and 6177182 known continuously show negative offset printing plates, covered with heat-absorbing in the near infrared region polymers that are cross-linkage reactions via cationic polymerization upon exposure to radiation in the middle infrared range. Near infrared chromophore parts are functionalized to a polymer skeleton through the ether and ammonium communication. From U.S. patent 6960422 known negative offset printing plates, which contain sensitive absorbing in the near infrared region covered by the base composition, including molecular dyes that absorb in the near infrared region, a radical generator, a radical polymerizable compound urethane, reactive polymer binders and other additives.

From U.S. patent No. 6582882 together and pending applications for U.S. patent 2003/0157433; U.S. patent 6899994 and patent applications U.S. 2005/0123853 known continuously show negative offset printing plates, which are covered with thermally exhibited by compositions containing a polymeric binder, initiator and polymerizable components. Described polymeric binders are copolymers having directionspanel polyethylene oxide and block polypropylene, or graft copolymers having directionspanel side chains of polyethylene oxide, co-polymerizable with Acrylonitrile, styrene and other monomers. Polymerizable components represent the viscous liquid oligomers containing numerous acrylic functional group. The initiator system contains dyes that absorb in the near infrared region, and compounds that produce radicals, such as triazine and salts iodine.

All of these coating compositions and printing plates show some disadvantages, such as having a sticky surface, which leads to difficulties in processing and storage, the manifestation of phase separation and/or superficial is th crystallization, the difficulty of obtaining the requirement of high power laser to achieve a display having a low adhesion to the substrate and, consequently, lack of provision of sufficient magnitude circulation in the press, are not continuously show, show low resistance to scratching, require an additional covering layer and/or special surface treatment of the base and are expensive to manufacture.
