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, chrome oxide, cobalt-chrome-aluminum and other dark, inorganic pigments.
- various fibers synthetic or natural, e.g. Cellulose, cotton, cellulose acetate, Viscose, paper, glass wool, nylon and polyester.
- 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 known imagewise UV exposure of a high pressure plate.
- a Such mask production differs in principle from an engraving of a printing plate.
- JP-A 6 230 568 discloses a photosensitive composition for the production of high-pressure and screen printing plates.
- the Composition comprises an emulsion of a hydrophobic polymer resin with a glass transition temperature> 45 ° C, a polymer of Polyvinyl alcohol type, photopolymerizable monomers and one Photopolymerization initiator.
- the hydrophobic polymer can it is for example PVC, polyacrylonitrile, polystyrene or Act PMMA.
- the script describes conventional production a high pressure plate using this composition by covering the photosensitive layer with a photographic Negative, exposure of the layer to UV light through the negative followed by developing the exposed layer using a detergent. The possibility of engraving a Print reliefs with a laser are not disclosed.
- the object of the present invention is a method to provide for the production of high-pressure plates, at which by means of coherent electromagnetic radiation records or printed products with high resolution in a short time can be.
- the object is achieved with a method for engraving recording using coherent electromagnetic radiation, using a material consisting of a support, a crosslinkable layer, optionally a cover layer, optionally a cover film, and the crosslinkable layer 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 to 99% and / or one or more copolymers, the structural unit in a significant proportion have, and also a polymer filler is 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.
- the particular advantage of using the filler with a predetermined Ceiling temperature limit is that the material for the high pressure is surprisingly usable and the Engraving speed can increase significantly without it Loss in print quality comes.
- the filler can be crosslinked or can be cross-linked or non-cross-linked, the filler can be expedient one or more of the following polymers:
- PS Polystyrene
- PMMA polymethyl methacrylate
- POM polyoxymethylene
- POM polytetrahydrofuran
- poly ( ⁇ -methylstyrene) polystyrene
- the filler in particle form in particular spherical or Approximately spherical in shape, the largest dimension being about 5-10 ⁇ m is.
- the polymeric filler can be coated with a Weight percentage from 1 to 49.9%, in particular from 2 to 25%, preferably 5-15%, based on the solids of the crosslinkable layer B) can be used.
- the polymeric filler has a ceiling temperature of less than 500 K and in particular from polymethyl methacrylate (PMMA) or from polyoxymethylene (POM) exists.
- PMMA polymethyl methacrylate
- POM polyoxymethylene
- the crosslinkable layer B becomes photochemical before the engraving recording (actinic radiation), thermally or by means of electron beams networked.
- the crosslinkable layer B) can also have a multilayer structure be, wherein at least one engravable material layer is provided which, in addition to the at least one polymeric binder B3) a polymeric filler B4) with a ceiling temperature of contains less than 800 K, in particular less than 600 K.
- additives e.g. Dyes, stabilizers or Plasticizer be incorporated.
- the coherent electromagnetic radiation for engraving recording is expediently laser radiation, in particular the radiation from a CO 2 laser.
- laser radiation in particular the radiation from a CO 2 laser.
- the filler B4) is in the form of pre-crosslinked or uncrosslinked polymer beads with diameters in Range of about 5-10 microns to the binder B3) is added.
- the Size is preferably below the desired resolution of the fine relief elements of the relief.
