  • Van Balen [21] A 1 NO 310 093 Attorney, Agent, or Fzrm-Walter Becker 0 [57] ABSTRACT [30] Forelgn Application Pnomy Data A printing blanket, especially for offset printing, com- NOV. 29, 1971 Germany 2159085 p g a Strength carrier y an intermediate y and an ink transfer layer comprising a polymer base, [52] [1.8. CI 161/162, 161/401, 161/160, finer materials containing hydroxyl groups and-high 51 1 lm Cl i /i molecular weight, surface active substances.
  • the blanket shown in the drawing consists of an in necessary multi layer strength carrying layer 1 provided with an if necessary porous intermediate layer 2, which is coated with a dye or ink transmitting layer 3 constructed according to the invention.
  • the blanket according to the present invention is characterized primarily in that the ink transmitting layer is constructed upon a base of polymers which essentially correspond to those used in the intermediate layer or at least are excellently fusable with them.
  • the mass or material made upon the base of this polymer and used to form the ink transmitting layer has a concentration between 50 and per cent by weight, with regard to the polymer portion of the material, of bright or transparent filler material containing hydroxyl groups.
  • the material also preferably contains antistatic, high molecular, surface active substances in a proportion of between 1 and 15 per cent by weight, likewise with reference to the polymer content.
  • magnesium silicates which contain hydroxyl groups and/or high molecular polyglycols improve the compatability of the mixture for the surface active substances and increase their conductivity.
  • the thickness of the layer of the ink transmitting layer constructed according to the invention should amount to at least 0.01 to 0.02 millimeters, preferably 0.05 millimeters, in order to produce in the layer a suf ficient deposit of slowly migrating surface active substance and to assure a better elimination of the electrostatic charges.
  • butadiene-acrylonitrile mixed polymerizates are preferred as polymers.
  • the polymers contain an admixture of thermoplastic synthetic materials, such as for example polyvinyl chloride, chlorinated polyethylenes, polyamides or the like.
  • the polymers contain fatty acid modified, constantly swelling factices (rubber substitutes) upon a castor oil base.
  • the selection of the filler material shows greater influences than can be at first expected.
  • Bright or transparent filler materials, especially silicates have shown themselves superior to carbon black.
  • Especially favorable is the insertion of a magnesium silicate containing hydroxyl groups (a vapor talc known under the trade mark Mistron).
  • filler materials containing hydroxyl groups and polyglycols with molecular weights between 5,000 and 20,000 permits a high dose of surface active substances and apparently also a control of their migration velocity, so that even with a layer thickness of only 0.01 to 0.02 mm, a sufficient deposit of surface active substances may be formed, which remains throughout the life of the blanket.
  • the coating measures formed according to the invention may be manufactured in a customary manner and applied to the surface of the blanket.
  • EXAMPLE 1 In an internal mixer at a temperature between 140 and 150 C, a blend is made of 100 parts by weight butadiene-acrylonitrile mixed polymerizates (28 to 38 percent acrylonitrile) with 30 parts by weight of polyvinyl chloride in the form of a polymerizate suspension. After cooling to about 90 C, 50 parts by weight of a fatty acid modified factice upon a Castor oil base and 25 parts by weight of a polyglycol ester of fatty acids of average chain length are mixed in.
  • the mixture obtained is worked into a brushable paste through the addition as solvent of ethyl acetate toluene (1:3).
  • the resulting mixture is applied to the prepared blanket foundation in a layer having a thickness of about 0.02 mm, and the thus obtained product is vulcanized.
  • a printing blanket especially for offset printing, which comprises a strength carrier layer, an intermediate layer, and an ink transfer layer, said ink transfer layer comprising a polymer base, bright filler material containing hydroxyl groups, and surface active substances having high molecular weights.
