  • the black, positive-acting, film-forming, electrophotographic ink used in the examples was prepared at an organosol/pigment ratio of 6 following the procedure described in Example 40 of U.S. 5,652,282 modified as follows.
  • the gel organosol prepared according to the procedure of Example 22 of U.S. 5,652,282 was mixed using a Silverson mixer (Model L2R, Silverson Machines, Ltd.) operated at the lowest speed setting. After mixing for five minutes, 1912 g of the homogenized organosol at 16.14% (w/w) solids in
  • NORPAR 12 were combined with 1031 g of NORPAR 12 (Exxon Chemical Co., Houston, TX), 51 g of MONARCH 120 carbon black (Cabot Corp., Billerica, MA), and 6.08 g of Zirconium HEX-CEM (OMG Chemical Company, Cleveland, OH) in a 4.0 liter polyethylene container. This mixture was then milled in ten vertical bead mills, each having a capacity of 0.5 liter (Model 6TSG-1/4, Aimex Co. Ltd., Tokyo, Japan) by placing 300 g of millbase and 390 g of 1.3 mm diameter Potters glass beads (Potters Industries, Inc., Parsippany, NJ) in each mill. Each mill was operated at 2,000 rpm for 1.5 hours without cooling water circulating through the cooling jacket of the milling chamber.
  • This 3% toner was tested on the toner plating apparatus described in U. S. 5,652,282.
  • the reflection optical density (ROD) was greater than 1.47 at plating voltages greater than 400 volts.
  • Example 1 A coating solution was prepared by adding Irgacure 1700 photoinitiator
  • the solution was then knife-coated onto polyethylene naphthalate film (available from Teijin Films, LTD) at a wet coating coverage of approximately 200 g/square meter and then dried for 3 minutes at 80°C to give a u.v.-curable adhesive-coated film.
  • the dry thickness of the adhesive layer was 1.0 mil.
  • the adhesive portion of the film was area printed using a liquid toner- based, black, positive-acting, film-forming, electrophotographic ink (prepared as described above) to a net optical density of 1.6.
  • the net optical density is equal to the white light optical density minus the white light optical density of the unprinted film, measured in reflectance mode with a Macbeth densitometer.
  • the net optical density corresponded to an ink net optical density of 1.3 for a paper substrate printed under identical conditions.
  • the adhesive-coated film was laminated to a white polyvinyl chloride substrate.
  • the adhesive was cured by exposing the printed, laminated article to ultraviolet radiation in air (40 units exposure using a Burgess Controlux Exposure Unit, available from Burgess Industries, Minneapolis MN). The article was then cut into strips measuring one inch wide.
  • Adhesive tape No.
  • An adhesive-coated polyethylene naphthalate film was prepared following the procedure of Example 1 except that Sartomer SR 610 polyethylene glycol diacrylate was used in place of Sartomer SR 259 polyethylene glycol diacrylate.
  • the dry thickness of the adhesive layer was 1.0 mil.
  • the film was then used to prepare a laminated article as described in Example 1 except that the temperature of the heated rollers used for lamination was 95-120°C.
  • the resulting article had a peel strength in excess of 3.5 pounds/inch (6.1 N/cm), which is sufficient to meet the requirements of ISO/TEC Standard No. 7810: 1995(E).
  • unprinted adhesive film was laminated to an identical white polyvinyl chloride substrate in an identical manner, and the peel strength measured. The peel strength was sufficiently high to cause tearing of the polyethylene naphthalate film.

  • a polyethylene terephthalate film (1 mil thick E2Q film available from Teijin Films, Ltd.).
  • Sartomer SR 610 polyethylene glycol diacrylate
  • Sartomer CN 966 A80 a urethane acrylate blended with tripropylene glycol diacrylate, was used.
