- Backing materials for offset printing plates are provided either by the consumer directly or by the manufacturer of precoated printing plates on one or both sides with a light-sensitive layer (copying layer), with the aid of which a printing image is generated photomechanically.
- the support carries the printing image areas and at the same time forms the hydrophilic background for the lithographic printing process in the non-image areas (non-image areas).
- Aluminum, steel, copper, brass or zinc, but also plastic films or paper can be used as the base material for such layers. These raw materials are processed by suitable operations such as. B. grain, matt chrome plating, surface oxidation and / or application of an intermediate layer in layer support for offset printing plates.
- the use of salts of these compounds is also mentioned, but is not specified in detail.
- DE-AS 10 56 931 describes the use of water-soluble, linear copolymers based on alkyl vinyl ethers and maleic anhydrides in light-sensitive layers for printing plates.
- these copolymers those in which the maleic anhydride component has not been reacted with, or more or less completely, with ammonia, an alkali metal hydroxide or an alcohol are particularly hydrophilic.
- DE-AS 10 91 433 discloses the hydrophilization of printing plate support materials based on metals with film-forming organic polymers such as polymethacrylic acid or sodium carboxymethyl cellulose or hydroxyethyl cellulose in the case of aluminum supports or a copolymer of methyl vinyl ether and maleic anhydride in the case of magnesium supports.
- water-soluble polyfunctional amino-urea-aldehyde synthetic resins or sulfonated urea-aldehyde synthetic resins are first used, which are in a water-insoluble state on the metal support be cured.
- a process is used to densify anodized aluminum surfaces, in which a solution is used at a temperature of at least 90 ° C. and a pH of 5 to 6.5 is applied, the water-soluble phosphonic acids forming complexes with divalent metals or their Contains salts (such as 1-hydroxyethane-1,1-diphosphonic acid or aminotrimethylenephosphonic acid) and Ca 2+ ions; these solutions can also contain dextrins.
- salts such as 1-hydroxyethane-1,1-diphosphonic acid or aminotrimethylenephosphonic acid
- the layer weight of the hydrophilic: adhesive layer on cellulose ether is 0.2 to 1.1 mg / dm 2 , the same layer weight is also given for the water-soluble salts.
- the mixture of cellulose ether and salt is in aqueous solution, optionally with the addition of an organic solvent and / or a Ten - sids coated on the support.
- hydrophilizing agents for printing plate support materials according to US Pat. No. 4,049,746 contain salt-like reaction products of water-soluble polyacrylic resins with carboxyl groups and polyalkyleneimine-urea-aldehyde-carboxyl groups and polyalkyleneimine-urea-aldehyde resins.
- GB-PS 1 246 696 describes hydrophilic colloids such as hydroxyethyl cellulose, polyacrylamide, polyethylene oxide, polyvinyl pyrrolidone, starch or gum arabic as hydrophilizing agents for anodized aluminum printing plate supports.
- the object of the invention is therefore to modify the hydrophilicity of support materials for offset printing plates in such a way that they are equally suitable as supports for positive, negative or electrophotographic photosensitive layers without the aforementioned disadvantages of known modification methods occurring.
- the invention is based on the known plate-, foil- or band-shaped carrier materials for offset printing plates on the basis of chemically, mechanically and / or electrochemically roughened, optionally an aluminum oxide layer produced by anodic oxidation or one of its alloys with a hydrophilic coating of at least one salt-like hydrophilic organic polymers on at least one surface of the carrier material.
- the carrier materials according to the invention are then characterized in that the salt-like hydrophilic organic polymer is a complex reaction product of a) a water-soluble organic polymer with acidic, phosphorus or sulfur-containing functional groups and b) a salt of an at least divalent metal cation.
- 1 to 3 preferably 2, coordination sites of the metal cation are occupied by the functional groups of the polymer, which probably acts as a chelating ligand.
- the water-soluble polymers used to produce the complex-type reaction products are in particular polvinylphosphonic acid, polyvinylmethylphosphinic acid, a phosphoric acid ester of polyvinyl alcohol, polyvinylsulfonic acid, polyvinylbenzenesulfonic acid, a sulfuric acid ester of polyvinyl alcohol or an acetal made of polyvinyl alcohol and a sulfonated aliphatic aldehyde.
- polyvinylmethylphosphinic acid these compounds are known from the literature.
- polyvinylmethylphosphinic acid is described for the first time in the simultaneously filed patent application P 31 26 627.4 (internal name Hoe 81 / K 038) entitled "Polyvinylmethylphosphinic acid, process for its preparation and its use”; it is produced by polymerizing vinylmethylphosphinic acid or its salts in the presence of radicals, by the action of electromagnetic radiation or by heating.
- the metal cations are generally used in the form of their salts with mineral acid anions or as acetates to prepare the complex-type reaction products; the divalent, trivalent or tetravalent, in particular the divalent, are preferred.

- these products are soluble in more or less acidic media and are precipitated quantitatively when the acidic solution is neutralized with alkali hydroxide or ammonia; they are insoluble in neutral or alkaline aqueous and in the usual organic solvents.
- the products can be precipitated by neutralizing the reaction solution with dilute alkali hydroxide or ammonia solutions, the unreacted starting pro products remain in the solution.
- the yields of these reactions are over 90%.

- the specified structure is likely to be present primarily in acidic solutions ö- L, with the addition of aqueous alkali metal hydroxide or ammonia solutions a plurality of ligand exchange reactions are possible on such complexes. Since the functional groups of the polymers used for the synthesis of the complex-like reaction products can themselves interact with the metal cation as bidentate ligands, the following complex structures are also possible as reaction products: Such chelate complexes arise in particular if the polymer solution is slowly added to an excess of the metal salt.
- the isolated and dried complex-like reaction products are preferably in 0.1 to 10%, in particular 0.5 to 3%, mineral acids, preferably phosphoric acid, in concentrations of 0.05 to 5%. , especially in concentrations of 0.1 to 1%.

Temperatures from 20 ° to 95 ° C., preferably from 25 ° to 60 ° C. and residence times from 2 seconds to 10 minutes, preferably from 10 seconds to 3 minutes, are found to be the most favorable for practical use. An increase in the bath temperature favors the chemisorption of the polymer-metal complexes on the substrate. This makes it possible to reduce the dwell times considerably, particularly in the case of continuous strip treatment.
- the immersion treatment is then expediently followed by a rinsing step with water, primarily with tap water.
- This rinsing process can serve on the one hand to remove excess treatment solution from the carrier, on the other hand the acidic treatment solution on the carrier becomes so strong by dilution with water shifted from the neutral point that the dissolved complexes can precipitate in the pores of the substrate and are thus firmly fixed on the support.
- the substrate treated in this way is then expediently dried at temperatures of 110 ° to 130 ° C.
- the treatment of the aluminum substrate can also be carried out as a two-stage process.
- the substrate is immersed, for example, in a 0.2 to 10%, preferably 0.5 to 5%, aqueous solution of the starting polymer.
- the substrate can then be transferred without prior rinsing or drying into a second bath which contains a 0.1% to saturated, preferably 0.5 to 10% aqueous salt solution with the polyvalent metal ions listed above.
- the rinsing and drying is carried out as in the one-step process.
- the complex-like reaction products described above are formed on the substrate during the treatment.
- This variant of the process can also be used to apply the complex-like reaction products of trivalent metal ions which are difficult to dissolve in strongly acidic media to the substrate.
- the support materials according to the invention thus produced can then be coated with various light-sensitive layers for the production of offset printing plates.
- the aluminum support materials for printing plates which are very common in practice, are generally mechanically (e.g. by brushing and / or with abrasive treatments), chemically (e.g. by etching agents) or before the photosensitive layer is applied electrochemically roughened (e.g. by AC treatment in aqueous HCl or HNO 3 solutions).
