Definitions

  • the invention relates to the use of an iron and manganese-containing aluminum alloy for the production of printing plate supports for a printing process and a printing plate based on such a support material and at least one reproduction layer.
  • Reproduction layers sensitive to radiation are used, for example, in the production of offset printing forms or photoresists, i. H. they are generally applied to a substrate by the consumer or by the industrial manufacturer. Metals such as zinc, magnesium, chromium, copper, brass, steel, silicon, aluminum or combinations of these metals, plastic films, paper or similar materials are used as layer supports in these copying materials. These substrates can be modified without a modifying pretreatment, but preferably after carrying out a surface modification such as mechanical, chemical and / or electrochemical roughening, oxidation and / or treatment with hydrophilizing agents (especially in the case of substrates for offset printing plates made of aluminum or one of its alloys) radiation-sensitive reproduction layer can be coated.
  • a surface modification such as mechanical, chemical and / or electrochemical roughening, oxidation and / or treatment with hydrophilizing agents (especially in the case of substrates for offset printing plates made of aluminum or one of its alloys) radiation-sensitive reproduction layer can be coated.
  • the usual radiation-sensitive reproduction layers usually also contain an organic binder (resins or the like) and optionally also plasticizers, pigments, dyes, wetting agents, sensitizers, adhesion promoters, indicators and other customary auxiliaries. These reproduction layers are developed after their irradiation (exposure) in order to produce an image from them, for example a printing form is obtained in this way.
  • organic binder resins or the like
  • plasticizers pigments, dyes, wetting agents, sensitizers, adhesion promoters, indicators and other customary auxiliaries.
  • those with a high Al content of more than 99.0%, in particular at least 99.5% are generally characterized by good to very good roughening properties, but they are often not suitable for modern processing methods from printing plates to printing forms sufficiently temperature stable, d. H. they tire, for example, as a result of the high temperatures of more than 180 ° C., in particular also of more than 240 ° C., which are required when baking positive-working reproduction layers.
  • Aluminum alloys with a lower Al content can often show better temperature stability, but are then usually inferior in their roughening properties, in particular in the uniformity of the roughening topography.
  • the production is carried out by casting the alloy with a certain growth rate on the solidification front and a certain temperature gradient in the liquid metal in the vicinity of the solidification front and a subsequent hot and / or cold working of the cast alloy with the The aim is to reduce the cross-section by at least 60%.
  • a preferred range for an Al-Fe-Mn alloy has an Fe content of 1.4 to 2.0% and an Mn content of 0.3 to 1.2%, this special alloy also containing Zn, Li, Cu, Mg and Si contains up to 1.5% in total and up to a maximum of 1.0% individually (single component), as well as other elements such as Ni, Cr, Co or B up to 1.0% in total and up to at a maximum of 0.3% each.
  • the object of the present invention is to use an aluminum alloy for the production of printing plate supports which, in terms of the quality of the surface topography after the roughening, in particular the electrochemical roughening, corresponds at least to the better materials of the prior art, without, however, their disadvantages in the thermal treatment to show.
  • the invention is based on the known aluminum alloys containing iron (Fe) and manganese (Mn), the Fe content being greater than the Mn content, for printing plates.
  • an alloy which consists of 1.2 to 2.1% Fe, 0.1 to 0.9% Mn - the sum of the Fe and Mn content being 1.3 to 2.2% - Remainder aluminum and manufacturing-related impurities;
  • it can still be up to 0.1% Si, 0.3% Ni, 0.3% Cu, 0.1% Mg, 0.1% Ti, 0.1% Zn, 0.3% Co as an upper limit - whereby the sum of the elements is not greater than 0.4% - and a total of a maximum of 0.15% and in particular a maximum of 0.05% of the elements B, Be, Bi, Ca, Cr, Ga, Li, Na, Pb, Sb, Sn, V and / or Zr at the expense of the rest of aluminum included to provide printing plate supports for a printing process.
  • the sum of the Fe and the Mn content is 1.5 to 2.2%.
  • the Fe content is 1.45 to 1.6%
  • the Mn content is 0.35 to 0.5%
  • the sum of the Fe and Mn content is 1.8 to 2.1 %.
  • Another object of the invention is a printing plate based on such a carrier material and at least one radiation-sensitive reproduction layer applied to the carrier material, the carrier material being in mechanically, chemically and / or electrochemically roughened and optionally anodically oxidized and hydrophilized form according to claims 5 and 6 .
  • the aluminum alloy used for the carrier material according to the invention which is in strip, plate or foil form, can be produced in particular according to the information in DE-C-2 423 597.
  • the metal is cast so that there is essentially no nucleation of intermetallic particles in the molten metal in front of the front between the liquid and solid metals.
  • the term "eutectic alloy” is also intended to mean a range of compositions of the alloys in the vicinity of the eutectics, in which it is possible to achieve the simultaneous deposition of the metallic aluminum phase and one or more fibrous intermetallic phases.
  • the casting alloy After the casting alloy has been produced, its further processing can be carried out by hot and / or cold machining (for example rolling), a cross-section reduction of at least 60% being achieved.
  • hot and / or cold machining for example rolling
  • cold machining means machining at a temperature of less than 250 ° C.
  • strip casting can also take place. For example, the cast alloy is heated to about 500 ° C and the hot rolling of the billet begins to descend to about 260 to 330 ° C at that temperature.
  • the strip thickness is reduced, for example, from approximately 3.0 mm to approximately 0.8 or approximately 0.3 mm
  • a further cold rolling can follow, in which the about 0.8 mm thick tape is also reduced to about 0.3 mm.
  • the carrier materials used have a thickness of 0.1 to 0.5 mm in particular, but deviations downwards and upwards are also possible.
  • the alloy used according to the invention differs from the prior art in the field of carrier materials for printing plates on the one hand by a high Fe content and a relatively high Mn content for a high Fe content and on the other hand by a high sum of both components.
  • the carrier materials for printing plates are preferably mechanically (e.g. by brushing and / or with abrasive treatments), chemically (e.g. by means of) in tape form or also in plate or film form before the reproduction layer is applied Etching agent) or electrochemically (eg by alternating current treatment in aqueous HCI or HN0 3 solutions) roughened on one or both sides; in particular, they are roughened mechanically and electrochemically or only electrochemically.
  • the average roughness depth R z of the roughened surface is in the range from about 1 to 15 ⁇ m, in particular in the range from 1.5 to 10 ⁇ m.
  • the roughness depth is determined in accordance with DIN 4768 in the version from October 1970, the roughness depth R z is then the arithmetic mean of the individual roughness depths of five adjacent individual measuring sections.
  • the flat support material Before the roughening, the flat support material can be pre-cleaned; it includes, for example, treatment with aqueous NaOH solution with or without degreasing agent and / or complexing agents, trichlorethylene, acetone, methanol or other commercially available aluminum stains.
  • an abrasive treatment can additionally be carried out, in particular a maximum of 2 g / m 2 being removed (up to 5 g / m 2 between the stages);
  • aqueous solutions of alkali metal hydroxide or aqueous solutions of alkaline salts are used as abrasive solutions or aqueous acid solutions based on HN0 3 , H 2 S0 4 or H 3 P0 4 .
  • non-electrochemical treatments are also known which essentially have only a rinsing and / or cleaning effect and, for example, for removing deposits formed during roughening ("Schmant") or simply for removal serve from leftovers; For example, dilute aqueous alkali hydroxide solutions or water are used for these purposes.
  • an anodic oxidation of the carrier material can then optionally follow in a further process step to be used, for example in order to improve the abrasion and adhesion properties of its surface (s).
  • the usual electrolytes such as H 2 S0 4 , H 3 P0 4 , H 2 C 2 0 4 , amidosulfonic acid, sulfosuccinic acid, sulfosalicylic acid or mixtures thereof can be used for anodic oxidation; in particular, H 2 S0 4 and H 3 P0 4 are used alone, in a mixture and / or in a multi-stage anodizing process.
  • the layer weights of aluminum oxide range from 1 to 10 g / m 2 , corresponding to a layer thickness of about 0.3 to 3.0 f.Lm.
  • the stage of anodic oxidation of the carrier material can also be followed by one or more post-treatment stages.
  • These post-treatment stages serve in particular to additionally increase the hydrophilicity of the aluminum oxide layer, which is often sufficient, while at least the other known properties of this layer are retained.
  • Reproduction layers sensitive to radiation are to be understood in principle as those which, after irradiation (exposure), possibly with subsequent development and / or fixation, provide an imagewise surface from which printing can take place.
  • Suitable layers also include the electrophotographic layers, i.e. H. those containing an inorganic or organic photoconductor.
