Definitions

  • the invention relates to a material for engraving recording by means of coherent electromagnetic radiation, consisting of carrier, crosslinkable layer, optionally a cover layer, optionally a cover film, the crosslinkable layer containing at least one ethylenically unsaturated compound and a polymerization initiator and at least one polymeric binder , which consists of a polyvinyl alcohol with a degree of hydrolysis of 50-99% and / or one or more copolymers, which make up a significant proportion of the structural unit exhibit.
  • Such materials are for printing forms for high pressure known.
  • WO 93/23252 describes a method for laser engraving an elastomer Single-layer flexographic printing plate described, wherein a mechanical, photochemical or thermochemical amplification of the Single-layer material and engraving with a selected pattern should take place for the production of the finished engraved flexographic printing plate.
  • the single-layer material contains reinforcing agents the mechanically and / or thermochemically and / or photochemically should work. Such reinforcing agents are advantageous for rubber-like flexo materials to improve the engraving in the With regard to a higher image resolution for packaging printing.
  • Radiation absorbing materials can be used as mechanical reinforcing means Pigments serve e.g.
  • finely divided metal particles such as aluminum, copper or zinc, alone or in combination with Carbon black, graphite, copper chromite, chromium oxide, cobalt-chromium-aluminum and other dark, inorganic pigments.

  • Such mechanical reinforcement means are for crosslinkable PVA binders cannot be used for high-pressure plates.
  • the CO 2 laser Due to the high energy input and its reliability, the CO 2 laser enables a good material removal rate during the engraving process.
  • EP-A 767 406 is an IR laser method for ablation an IR-sensitive layer for the production of a mask for imagewise UV exposure of a high-pressure plate known.
  • a Such mask production differs in principle from an engraving of a printing plate.
  • the present invention is based on the object Material for engraving recording for high pressure plates provide where medium coherent electromagnetic Radiation records or printed products with high resolution can be produced in a short time.
  • the object is achieved with a material for engraving recording by means of coherent electromagnetic radiation, consisting of carrier, crosslinkable layer, optionally a cover layer, optionally a cover film, the crosslinkable layer comprising at least one ethylenically unsaturated compound and a polymerization initiator and at least one polymeric binder contains, which consists of a polyvinyl alcohol with a degree of hydrolysis of 50 to 99% and / or one or more copolymers, the structural unit in a significant proportion have, solved according to the invention, if a polymer filler is also provided which has a ceiling temperature of less than 800 K, in particular less than 600 K.
  • Croiling temperature is the temperature at which the depolymerization of a macromolecule from the chain end begins.
