Definitions

  • the invention relates to a method for producing sensitized planographic printing plates from pretreated aluminum supports and light-sensitive copying layers, an intermediate layer being applied between the carrier and copying layer, and the use of these planographic printing plates for offset printing.
  • Offset printing plates generally consist of a layer support, on which a radiation-sensitive reproduction layer is applied, with the aid of which an image is photomechanically generated from a template. After the printing form has been produced, the layer support carries the color-bearing image areas during later printing and at the same time forms the water-bearing image background (non-image areas) in the image-free areas.
  • the substrate must always have a certain porous surface structure so that its surface can retain enough water to be sufficiently repellent to the printing ink used in printing.
  • Aluminum, steel, copper, brass or zinc foils can be used as the carrier material for light-sensitive layers.
  • Aluminum and aluminum alloys are generally used for offset printing plates, which are modified by a series of pretreatment steps in order to ensure good adhesion of the radiation-sensitive layer and thus long print runs.
  • aluminum is roughened mechanically, chemically and / or electrochemically, if necessary pickled and anodized.
  • electrochemical roughening in HCl and / or HNO3 and the anodic oxidation in H2SO4 and / or H3PO4 as standard methods.
  • the patent literature includes methods such as silicating (see, for example, DE-OS 25 32 769 or US Pat. No. 3,902,976), treatment with complex fluorides (see, for example, DE-AS 1 300 415 or US Pat. No. 3 440 050), or with polyvinylphosphonic acid (see, for example, DE-PS 1 134 093, US-PS 3 276 868, DE-PS 1 621 478, US-PS 4 153 461).
  • the methods described above have more or less major disadvantages. For example, treatment with alkali silicates has to accept a certain deterioration in shelf life.
  • US Pat. No. 4,483,913 describes a process for producing a sensitized planographic printing plate from a mechanically pretreated, anodized aluminum support with a light-sensitive copying layer, a thin layer of aminopropyltriethoxysilane or the ammonium chloride derivative N-trimethoxysilyl-propyl-N between the carrier and the copying layer , N, N-trimethylammonium chloride is applied.
  • PVPS polyvinylphosphonic acid
  • Carrier materials treated with PVPS also tend to show signs of aging when stored uncoated. These manifest themselves in decreasing hydrophilicity as well as in a reduced windability of negatively working light-sensitive layers, which are coated only a long time after the carrier has been produced.
  • the object of the invention was to demonstrate a class of compound which, as an intermediate layer between the support and the copying layer, brings about an increase in the hydrophilicity of the non-image areas without the adhesion of the to have a negative influence on the radiation-sensitive layer on the carrier material, thus avoiding or restricting the aforementioned disadvantages of known treatment agents.
  • silanes are also used as adhesion promoters in so-called dry offset printing plates.
  • the "dry" planographic printing plate is based on the principle of a differentiation between printing and non-printing parts by means of a color-accepting, light-sensitive polymer layer and an oleophobic, oily paint-repellent and thus non-printing silicone rubber layer.
  • a photosensitive polymer layer is applied to a silicone rubber layer located on a metal support, exposed imagewise and developed, so that, for example in the case of a negative-working plate, the silicone rubber layer is exposed at the unexposed areas, while on the exposed parts the layer hardened by actinic radiation and an insoluble polymer layer is formed in the developer.
  • a silicone rubber with high color repellency does not have good adhesion to other materials due to its special properties, a silane coupling agent is used, which acts as an adhesive contact between the carrier and silicone rubber (see, for example, DE-PS 2 357 871 and DE-PS 2 323 453).
  • the present invention relates to a process for producing a sensitized planographic printing plate from a mechanically, chemically and / or electrochemically pretreated and anodically oxidized aluminum support and a light-sensitive copying layer which is applied to this support, which is characterized in that between the support and Copying layer a thin layer of a hydrolyzate or condensate of at least one silane of the general formula (I) X- (CH2) y -Si (R1) n (OR2) 3-n (I), wherein R1 and R2 are the same or different from each other and represent alkyl radicals having 1 to 9 carbon atoms or aryl radicals having 6 to 12 carbon atoms and X represents one of the radicals ZO3S-Ar- or HalO2S-Ar- stands for R3 is hydrogen, an alkyl radical having 1 to 9 carbon atoms, a carboxylic acid radical having 1 to 9 carbon atoms or one of this carboxylic acid radical and that bonded to R3 formed carb
  • silanes of the formulas given above are used in hydrolyzed or condensed form.
