  • the product which was a cationic acrylic polymer aqueous solution, had a solids content of 32.6 percent by weight (determined by weight difference of a sample before and after heating at 110°C. for one hour), and a pH of 5.25. All % solids values are % by weight.
  • Coatings were applied to blank 8%" x 11" Teslin ® TS 1000 sheet. Coating weight is measured by difference using an electronic balance . • The blank sheet is weighed. • Coating is applied to the front side using a #9 wire- wrapped rod. • The sheet is baked at 95° C in a textile oven (Model LTF from Werner Mathis AG, Zurich, Switzerland) for 2 minutes .
  • Coating weight in milligrams/square-inch is determined by dividing weight difference in milligrams by coated area.
  • Test prints from the coated Teslin sheets were generated off of an HP960C printer, set to normal default print mode. Optical density values were measured using an X- Rite ® densitometer, model type 418, normalized against a Macbeth ® black/white standard plate. Test prints were also generated using uncoated Teslin TSIOOO for comparison. Optical density values are listed in the following table.
  • Example 20 [00182] Several 6,600ft rolls of 10.5mil Teslin TSIOOO were sized with coating composition described in Example 19 in accordance the technique described in Example 19. The resultant rolls was converted into 8.5" x ll"sheets, grain long. Test prints were generated off of an HP960C printer, set to best ink jet photo grade matte finish. Both sides of the substrate were printed. The optical density of color bars representing the five primary color/ink types : composite black, cyan, magenta, yellow and pigment black were measured. The printed color bars were submerged in tap water for 15minutes and the resultant optical densities measured. The procedure was then repeated after a total of 24hours of continuous soaking. The optical density values are given in the following tables .
  • Example 21 Sheets 26-inch x 38-inch of treated Teslin TSIOOO substrate, 10.5mils thick, were cut from a master roll in the grain long direction.
  • the Teslin had been coated with 3 passes on each side (3x3) using the same coating composition as described in Example 19 and the same Flexographic coating technology described in Example 19.
  • One coated Teslin sheet was placed on top of one 26-inch x 38-inch sheet of 0.21-inch polyvinylchloride (PVC), supplied by Empire Plastics. The PVC sheet was cut in the grain long direction.
  • a sheet 27-inch x 39-inch of 2-mil clear polyester was placed over the Teslin sheet to act as a release liner.
  • This release liner was removed from the composite sheet following lamination and is not an integral part of the final composite sheets.
  • This construction was placed between two 27" x 39" x 30mil polished stainless steel metal plate. The resultant stack was then placed between two 27" x 39" x 125mil un-polished non- corrosive metal plates. This entire construction was placed 70
  • the Teslin had been coated with 3 passes on each side (3x3) using the same coating composition as described in example 1 and the same Flexographic coating technology described in example 2.
  • One coated Teslin sheet was placed on top of one 20-inch x 25-inch sheet of 0.10-inch polyvinylchloride (PVC), supplied by Empire Plastics. The PVC sheet was cut in the grain long direction. Below the PVC ply was a second ply of 20-inch x 25-inch x lOmil PVC, cut grain short.
  • PVC polyvinylchloride
  • the resultant stack was placed between buffer pads .
  • the buffer pads are a combination polyamide fiber and mechanical rubber, manufactured and supplied by Yamauchi Corporation, designed to more uniformally distribute temperature and press during thermal lamination.
  • the resultant stack plus buffer pads was then placed between two slightly larger 125rr.il un-polished non-corrosive metal plates. This entire construction, referred to as a book, was placed in a TMP laminating press, preheated to 300°F.
  • the composite construction was compression laminated at a pressure of 203psi for 18minutes at a temperature of 300°F.
