  • Inkjet recording medium 10 is comprised of a hydrophilic, microporous, polymeric membrane 12 having a hygroscopic layer 14 thereon
  • the layer 14 can be coated on or laminated to the membrane 12 using techniques known to those skilled in the art of coating or laminating of multiple layered constructions
  • Nonlimiting examples of coating or laminating techniques include notched bar coating, curtain coating, roll coating, extrusion coating, gravure coating, calendering, and the like.
  • Hydrophilic, microporous, polymeric membrane 12 is hydrophilic and receptive of aqueous solvents typically used in inkjet formulations.
  • Microporous membranes are available with a variety of, pore sizes, compositions, thicknesses, and void volumes Microporous membranes suitable for this invention preferably have adequate void volume to fully absorb the inkjet ink discharged onto the hydrophilic layer of the inkjet recording medium It should be noted that this void volume must be accessible to the inkjet ink In other words, a microporous membrane without channels connecting the voided areas to the hygroscopic surface coating and to each other (i.e., a closed cell film) will not provide the advantages of this invention and will instead function similarly to a film having no voids at all.
  • Void volume is defined in ASTM D792 as the (1 -Bulk density/Polymer density)* 100. If the density of the polymer is not known, the void volume can be determined by saturating the membrane with a liquid of known density and comparing the weight of the saturated membrane with the weight of the membrane prior to saturation. Typical void volumes for hydrophilic, microporous, polymeric membrane 12 range from 10 to 99 percent, with common ranges being 20 to 90%. Void volume combined with membrane thickness determines the ink volume capacity of the membrane. Membrane thickness also affects the flexibility, durability, and dimensional stability of the membrane. Membrane 12 can have a thickness ranging from about 0.01 mm to about 0.6 mm (0.5 mil to about 30 mils) or more for typical uses.
  • the thicknesses are from about .04mm to about .25mm (about 2 mils to about 10 mils).
  • the liquid volume of typical inkjet printers is approximately 40 to 140 picoliters per drop.
  • Typical resolution is 1 18 to 283 drops per centimeter.
  • High resolution printers supply smaller dot volumes.
  • Actual results indicate a deposited volume of 1.95 to 2.23 microliters per square centimeter with each color. Solid coverage in multicolor systems could lead to as high as 300% coverage (using undercolor removal) thus leading to volume deposition of 5.85 to 6.69 microliters per square centimeter.
  • Hydrophilic, microporous, polymeric membrane 12 has a pore size that is less than the nominal drop size of the inkjet printer in which the inkjet recording medium is to be used.
  • the pore size may be from 0.01 to 10 micrometers with a preferred range of from 0.5 to 5 micrometers with pores on at least one side of the sheet.
  • the porosity, or voided aspect, of membrane 12 need not go through the entire thickness of the membrane, but only to a sufficient depth to create the necessary void volume. Therefore, the membrane may be asymmetric in nature, such that one side possesses the aforementioned properties, and the other side may be more or less porous or non-porous. In such a case, the porous side must have adequate void volume to absorb the liquid in the ink that is passed through the hygroscopic layer 14.
  • Nonlimiting examples of hydrophilic, microporous, polymeric membranes include polyolefins, polyesters, polyvinyl halides, and acrylics with a micro-voided structure. Preferred among these candidates are a microporous membrane commercially available as "Teslin” from PPG Industries as defined in U.S. Pat. No. 4,833,172 and hydrophilic microporous membranes typically used for microfiltration, printing or liquid barrier films as described in U.S. Pat. Nos. 4,867,881 , 4,613,441 , 5,238,618, and 5,443,727. Teslin microporous membrane has an overall thickness of approximately 0.18 mm, and the void volume has been measured experimentally to be 65.9%.
  • the ink volume capacity of the membrane is thus 1 1.7 microliters per square centimeter. Therefore, this membrane has sufficient void volume combined with thickness to fully absorb the ink deposited by most inkjet printers, even at 300% coverage, without considering the amount retained in the hygroscopic layer.
  • Membrane 12 can optionally also include a variety of additives known to those skilled in the art Nonlimiting examples include fillers such as silica, talc, calcium carbonate, titanium dioxide, or other polymer inclusions. It can further include modifiers to improve coating characteristics, surface tension, surface finish, and hardness.

  • Hygroscopic layer 14 can be a coated layer or laminated layer on that portion of membrane 12 upon which the inkjet image is to be formed. Thus, layer 14 need not cover completely the membrane 12. Nor need layer 14 cover both sides of membrane 12. Layer 14 preferably lies substantially on the surface of membrane 12 and does not contact the inner pore surfaces of the membrane.
  • At least one side of membrane 12 may be covered at least in part by layer 14 and the other side may be sealed or coated with another material, such as an anti-static coating, adhesive, barrier layer, light blocking layer, strength enhancing layer, etc.

  • Hygroscopic layer 14 may be formed on membrane 12 using a number of techniques, including coating, laminating, or co-extrusion.
  • a hydrophilic coating solution When a hydrophilic coating solution is applied to the membrane, solution viscosity and concentration will affect the performance of the resulting inkjet recording medium.
  • low viscosity coating solutions coated on membranes with very high porosity and/or large pore size tend to fill the pores, resulting in a coated membrane that is saturated with hygroscopic polymer and has little or no coating on the surface.
  • Membranes coated in such a manner do not meet the requirements of this invention because the imaged medium usually exhibits lower image density and contrast and can dry more slowly. Techniques for achieving deposition of the hygroscopic layer 14 on the membrane 12 are demonstrated in the examples.
  • Solution viscosity of coating solutions is controlled by a variety of factors including coating solvent, polymer solubility, polymer molecular weight, temperature, etc.
  • low viscosity solutions are considered solutions with intrinsic viscosity of less that 100,000 centipoise when measured with an instrument such as a Brookfield viscometer.
  • Layer 14 can have a thickness ranging from about 2 micrometers to 35 micrometers. Preferably, the thicknesses are from about 3 micrometers to 15 micron. Greater thicknesses tend toward the problem of surface tackiness and curl.

Examples herein were evaluated with a Gretag SPM50 densitometer from Gretag Limited, CH-8105 Regensdorf, Switzerland. Other instruments will give similar comparisons, but not necessarily the same values. Dry times were measured subjectively by imaging a solid area and determining the length of time until the image did not smudge or smear when rubbed lightly. Dot spread is determined by measuring a single dot line. The lower the number is, the lower is the dot spread. Zero dot spread allows the most accurate reproduction, however, some dot spread will occur because of the spherical drop striking a flat plane and wetting the surface.

Les utilisations possibles de ce support d'impression par jet d'encre concernent, entre autres, les transparents pour rétroprojecteurs et les transferts graphiques tels que ceux utilisés sur les panneaux publicitaires extérieurs. Une seconde réalisation de l'invention concerne un élément auto-adhésif disposé sur au moins une partie du côté de la membrane polymère, microporeuse et hydrophile opposé à la couche hygroscopique contenant l'image précise et permanente.
