Definitions

  • the invention relates to a multilayer correction material on a siliconized carrier film, which without the Use of organic solvents or suspending agents is producible and a method for its production and its use.
  • DE-A-4 129 413 describes the production of a multilayer correction material that without the use of organic solvents and without the use of tear-promoting cellulose derivatives are produced can. This is due to a special structure of the Cover layer forming coating agent and the vote with the overcoat coating responsible for the liability reached. It is on the dried An aqueous overcoat coating applied, which is a polyethylene wax dispersion, an anionic Polyacrylate dispersion and optionally one Contains emulsifier and other conventional additives.
  • the aim of the invention is now a multilayer correction material, especially in the form of a rolled up To provide tape of the type described above, the without the use of organic solvents, i.e. H. that is produced alone in aqueous solution or suspension can be.
  • Another object of the invention is a to provide such transmission or correction means, that does not require a demolition agent as an additive.
  • it is still an aim of the invention, on one To do without an overcoat that contains a wax dispersion.
  • the aforementioned goals are achieved with a Correction and / or marking means achieved that one removable, inscribable arranged on a carrier Film that is covered with an adhesive, characterized in that the writable film or Top layer is a film-forming, non-brittle binder and has a brittle binder at room temperature.
  • binders can also be used as brittle binders are used, which initially have film-forming properties have, but together with the others Additives, especially with pigments a brittle mass forms.
  • Film-forming binders are, for example, terpolymers Dispersions based on vinyl acetate and Acrylic acid esters, such as those under the brand name Macrovil 21 2 G from Indulor Chemie GmbH, 49572 Ankum, Germany.
  • Another one Film-forming binder to be used according to the invention are, for example, copolymers based on Acrylic acid esters using acrylonitrile as they do are available under the name Arconal 85 D.
  • Brittle-acting binders are, for example Acrylic polymers, especially those in ammonia, as they for example under the name Carboset 537 from B.F. Goodrich, Cleveland, Ohio, as a 35% solids dispersion are distributed in ammoniacal water.
  • Another one brittle binders are copolymers containing carboxyl groups based on acrylic acid esters, such as commercial under the brand name Acronal V 205 are available.
  • Transliner In the manufacture of Correction films contain pigments covering the film layer, such as titanium dioxide and fillers.
  • a fluorescent dye such as for example, aminotriazine formaldehyde cocondensates contain organic dyes.
  • aqueous suspension from a brittle and a film-forming, non-brittle binder together with a pigment and / or dye and optionally Fluorine wetting agents such as FC 170 C and defoamers, such as Acitan 281, for example, with hydrophobic Silicas, synthetic copolymers and added non-ionic emulsifiers.
  • FC 170 C and defoamers such as Acitan 281
  • hydrophobic Silicas such as 2-amina-2-methyl-1-propionate
  • fillers and surfactants Agents and, if necessary, with thickeners to add.
  • Such an aqueous suspension is then applied by means of a doctor blade onto a carrier film which is preferably siliconized differently on both sides.
  • carrier films are known to the person skilled in the art and consist, for example, of polyester, polyethylene terephthalate, polypropylene, polyethylene or polyvinyl chloride.
  • the marking or covering and inscribable layer containing dyes and / or pigments is expediently applied with a solids content of 30-80%, preferably 40-70%, in particular 50% by weight.
  • the wet application rate is 15 - 70 g / m 2 .
  • a layer thickness of 20-60 ⁇ m, in particular 35-45 ⁇ m is achieved in the wet state, which is 8-30 ⁇ m, preferably 10-25 ⁇ m thick in the dry state.
  • Acronal V205 as a brittle binder in the form of a 69% aqueous dispersion
  • 3.75 kg Acronal 85D as a film-forming binder in the form of a 55% aqueous dispersion
  • 0.44 kg AMP 90 as a pH stabilizer (2-amino-2-methyl-1-propionate with 10% water)
  • 0.19 kg Surfynol CT 141 as a surface-active agent to improve the aqueous pigment dispersion
  • 0.31 kg Collacral VL as a thickener in the form of a 3% solution a vinylpyrrolidone copolymer
  • 0.16 kg of Forbest 150 W as a defoamer
  • 0.005 kg of carbon black (carbon black FW2) as a tinting agent
  • a marking agent produced in this way has good Tear off properties.
