It preferably affects one Cleaning medium for printing forms using laser-induced thermal transfer ribbon technology were illustrated. Furthermore, the use of the cleaning medium according to the invention disclosed in an extinguishing process. The invention also relates to concentrates of the cleaning medium and their use in containers for storage, transportation and Application.
- EP-B-0 570 879 relates to a repeated method and apparatus Erasing the ink-carrying layer from the surface of an illustrated, printing form intended for offset printing. You lead one pressurized solvent-free water jet using an extinguishing device at an angle on the illustrated surface of the printing form, causing this is cleaned.
- the solvent-free pressure, essentially medium consisting of water can contain abrasive additives, e.g. sand or the like, or chemical additives that have wax-dissolving properties have included to increase the removal rate of the beam.
- EP-B-0 693 371 discloses an erasable printing form and a method and a device for erasing and regenerating the printing form.
- the document teaches that after the printing process, the ink residues first and the imagewise applied coating by a cleaning medium removed, for example wiped.
- the cleaning medium is a Solvent or solvent mixture that contains no solid components.
- the surface of the printing form is then coated mechanically grated.
- a cleaning medium containing polishing agent for example a common plate cleaner that is used for manual cleaning of Printing forms are generally used. The plate cleaner is then removed with water, for example.
- the mechanical interaction between the cleaning media and the printing form is carried out by means of a cleaning device which is equipped with a Cleaning cloth or cleaning fleece is provided by a feed roller (Fresh roll) pressed against the printing plate via another roller and then is wound up on a winding roller (dirt roller).
- a feed roller Frsh roll
- Dirt roller a winding roller
- EP-B-0 698 488 discloses a method and an apparatus for Manufacture of a printing form known, by means of a laser from a Thermal transfer film plastic mass on a rotating printing form cylinder is transmitted figuratively. The material transferred from the thermal transfer ribbon forms the ink-bearing layer on the printing form.
- thermal transfer ribbon or a thermal transfer ribbon disclosed for imaging lithographic printing forms comprising a substrate layer and a donor layer applied thereon, wherein the substrate layer made of at least one polymer mass, preferably PET exists that has at least the following properties: mechanical Stability at a temperature> 150 ° C; Transmission> 70% for light of the Wavelength from 700 to 1600 nm; the donor layer at least the following Components include: a substance that strikes the radiant energy from Can convert laser light into thermal energy, preferably carbon black, a polymer the acidic groups and / or their optionally substituted amide groups comprises, preferably a styrene / (meth) acrylic acid / (meth) acrylic ester copolymer and optionally a wetting aid, preferably methyl ethyl ketone.
- the object of the present invention is to solve the known problems Formulations, being a simple on the essential ingredients optimized product is sought, so that one preferably essentially without additional stabilizing agents that are not part of the cleaning process itself participate, and cause possible interference in the following planographic printing can get along.
- Another task is the provision of concentrates and in the provision of these concentrates in containers.
- organic or inorganic acids can be used to provide the intended pH of 1-4 of the aqueous solution of the cleaning medium according to the invention.
- Inorganic acids are preferred for economic reasons.
- the inorganic acids must not adversely affect the printing form cylinder chemically.
- Oxygen acids of the fifth and sixth main group of the Periodic Table of the Elements as well as hydrohalic acids would be conceivable.
- Phosphoric acid has proven to be particularly suitable.
- Phosphoric acid is physiologically relatively harmless, is available at low cost, is durable and does not adversely affect the surface of the printing form. It is believed that the phosphoric acid forms relatively poorly soluble phosphates and hydroxyphosphates on the surface of the printing form, which supports the hydrophilization process by forming hydrophilic centers.
- phosphoric acid has a phosphating effect on steel surfaces in the pH range 2.8-3.6.
- Surface phosphates such as hopeit (Fe 3+ ) and in the presence of Zn phosphophyllite (Zn 2 Fe 2+ (PO 4 ) 2 * 4H 2 O) are formed.
- Contact angle measurement accordinging to Owens, Wendt and Rabel) on Ni and Fe-based printing forms show an increase in the surface tension by about 30 mN / m and an increase in the polar fraction by 30% after using phosphoric acid cleaners.
- the derivable dipole-dipole interactions on the substrate surface lead to better wetting by "dirt" covered substrate areas and to the generally accepted idea in the paint industry that FePO 4 * PO 4 layers significantly improve the adhesion of polymer coatings.
- the dissolving power of phosphoric acid for printing ink in combination with the other components mentioned above is sufficiently high.
- the acids mentioned above are used as a solution in a concentration range from 10% to almost 100%, in particular 30% to 90%.
- the usual shipping concentration for phosphoric acid is between 80 and 90%, usually around 85%.
- 2 g to 30 g of the aforementioned acid preferably 4 g to 15 g, in particular 5 g to 10 g, are used.
- any pH can be set ⁇ 10 generating substances are used. All completely solved are suitable Hydroxides of alkali metals, alkaline earth metals and ammonia, ammonium and phosphonium compounds. Alkali metal hydroxides are particularly preferred and carbonates. Sodium hydroxide and potassium hydroxide are again preferred, sodium hydroxide is particularly preferred.

- the amount used is an aqueous solution with a concentration of 0.5 mol / l at 30 to 60 g per 100 g of formulation, in particular 40 to 50 g, particularly preferably 44 to 46 g, per 100 g formulation.
- a particularly preferred amount is in the case of sodium hydroxide in the range of 44 to 46 g / 100 g of a 0.5 mol / l NaOH solution.
- the abrasive must not adversely affect the printing form or cleaning cloth during application and the mechanical treatment of the printing forms.
- the structure and hardness of the abrasive should be such that the printing form is not adversely affected abrasively, but the removal process of the printing ink residues on the printing form, in particular encrusted printing ink residues, and the imaging material is effectively supported.
- the abrasive particles of the abrasive remain in suspension for as long as possible.
- known abrasives such as ⁇ -aluminum oxide (calcination temperature approx. 1200 ° C.), are only of limited suitability because they have no surface charge and are therefore difficult to disperse or difficult to form a colloidal solution.
- the abrasive grain size it has been found that a size ⁇ 1 ⁇ m, preferably ⁇ 0.1 ⁇ m, particularly preferably ⁇ 50 nm, particularly preferably in the range between 5 and 35 nm, in particular between 10 and 15 nm (focus on the size distribution) is particularly suitable.
- the zeta potential should be at least 10, in particular 20, particularly preferably 35 mV.
- the range of the zeta potential should be 0 to 40 mV without additives in the case of Al 2 O 3 -C at a pH ⁇ 9 and at pH ⁇ 9 in the case of, for example, Aerosil OX50 (Degussa-Hüls) are between - 70 mV and + 20 mV.
- the material of the abrasive particles is preferably selected from metal oxides or mixed metal oxides of the general formula M III O, M III 2 O 3 , M IV O 2 , M II, III 3 O 4 , where M II is selected from the metals of main group II, M III is selected from the metals of III.
- the main group, transition metals and the lanthanides and M IV is selected from the metals or metalloids of the IV main group and the transition metals.
- Aluminum oxide, zirconium oxide, silicon dioxide, zinc oxide and iron oxide are preferred.
- the effect of the abrasives and thus their properties show a homogenization (symmetrical Abott curve) of the R z values when used on Ni and Fe-based substrates. These effects can be determined using a perthometer (Fokodyn laser scanner) or white light interferometer. In addition, after use, suitable abrasives show a contribution to increasing the polar portion of the surface tension.
- ⁇ -aluminum oxide for example Al 2 O 3 -C from Degussa, is particularly suitable for the abrasive particles in question.
- the Al 2 O 3 -C (Degussa) with a basic character (CAS 1394-28-1) is produced by high-temperature hydrolysis of an AlCl 3 .
- the resulting primary particles are all cubic with rounded corners (SEM) with an average size of the primary particles of 13 nm.
- BET investigations (DIN 66131) show no mesopores in hysteresis tests and therefore the particles have no internal structure (in contrast to ⁇ - Al 2 O 3 , which is used in chromatography due to its internal structure).
- the pH value of a 4% by weight aqueous dispersion is greater than 7.5 (DIN ISO 787 / IX) after removal of hydrochloric acid impurities and indicates that the surface OH groups are weakly alkaline.
- the specific density of Al 2 O 3 -C is approx.3.2 g / ml and the dielectric constant is 5.
- the abrasive is used in an amount of 1-15 g, preferably 2-20 g, more preferably 2.5-8, and especially 3-6 g per 100 g of formulation used.
- the surfactant is the surfactant
- the surfactant serves, among other things, to cause the micelle formation of the oleophilic color residues, so that the oleophilic color residues can be emulsified in the water and carried away from the surface. Furthermore, the surfactant acts as an emulsifier between the aqueous, acidic or alkaline phase and the hydrocarbon phase. In general, any surfactant is suitable for this process. Of the known ionic surfactants, such as cationic, anionic and ampholytic, cationic and anionic surfactants are most suitable. It has been found that anionic surfactants which contain a polyoxyalkylene chain in their molecule are particularly suitable.
- a preferred class of these compounds consists of a polyoxyalkylene radical bonded to an aromatic nucleus which carries an acidic group such as a sulfone, sulfate, carboxyl or phosphate group via an alkylene bridge.
- Preferred is a surfactant with a polyoxyethylene chain with 2 to 12 ethylene oxide units, 2 to 16 methoxide units or 2 to 7 propoxide units, bonded to an aryl radical which is substituted by a sulfate or sulfonic acid group bonded via an alkylene group.
- the surfactant Triton X-200 is particularly preferred.
- Triton X-200 essentially maintains its technical properties regardless of pH; for example, it does not precipitate out when the pH changes or loses a substantial part of its surfactant behavior.
- Triton X-200 shows excellent antistatic properties, as shown in the field of AgX photography. This is presumably due to the SO 3 Na group and the (CH 2 CH 2 O) chain.
- non-ionic surfactants except alkyl polyglycosides, alkyl polyglycol ethers are only suitable for the aforementioned purpose to a limited extent, since they are, for example tend to from metal surfaces, such as the surface of a printing form, to be adsorbed. Therefore, non-ionic surfactants should either be avoided or only as a co-surfactant mixed with the aforementioned ionogenic Surfactants are used. Possible mixing ratios are 1:10 to 10: 1.
- the concentration of the surfactant is in the range from 0.1 to 50 g, in particular 1 g to 50 g, per 100 g of formulation, in particular 2 g to 10 g per 100 g of formulation, particularly preferably 3 g to 8 g per 100 g formulation.
- a preferred class of surfactants are alkylaryl polyglycol ether sulfates, e.g. Sodium alkylaryl polyether sulfonate (CAS No.: 2917-94-4), Union Carbide Benelux N.V., with a CMC (critical micelle concentration, at 100% by weight) of 230 ppm.

- solvents that are suitable in principle are aromatic Hydrocarbons, aliphatic hydrocarbons both unbranched as well as branched (isocarbons), esters and ketones, however also organic solvents with heteroatoms in the chain or on the Chain are substituted.
- the aliphatic of these solvent classes proved to be Solvents are particularly suitable for a variety of reasons.
- Aromatic Solvents such as toluene, mesitylene, cumene etc., are, although they have a solvent power often show very good results due to physiological or toxicological Concerns, but also because of their inclination, plastic and rubber parts attack in the device, not preferred as the only solvent.
