Definitions

  • This invention relates to an ink jet recording element, more particularly to a porous ink jet recording element and a printing method using the element.
  • ink droplets are ejected from a nozzle at high speed towards a recording element or medium to produce an image on the medium.
  • the ink droplets, or recording liquid generally comprise a recording agent, such as a dye or pigment, and a large amount of solvent.
  • the solvent, or carrier liquid typically is made up of water, an organic material such as a monohydric alcohol, a polyhydric alcohol or mixtures thereof.
  • An ink jet recording element typically comprises a support having on at least one surface thereof an ink-receiving or image-forming layer.
  • the ink-receiving layer may be a porous layer which imbibes the ink via capillary action or a polymer layer which swells to absorb the ink.
  • Ink jet prints prepared by printing onto ink jet recording elements, are subject to environmental degradation. They are especially vulnerable to water smearing and light fade.
  • ink jet dyes are water-soluble, they can migrate from their location in the image layer when water comes in contact with the receiver after imaging.
  • Highly swellable hydrophilic layers can take an undesirably long time to dry, slowing printing speed, and will dissolve when left in contact with water, destroying printed images.
  • Porous layers speed the absorption of the ink vehicle, but often suffer from insufficient gloss and severe light fade. Porous layers are also difficult to coat without cracking.
  • WO-A-95 16561 discloses a mixture, for an image-receiving layer of an inkjet recording element, comprising gelatin, mordant and poly(methyl methacrylate) beads.
  • the carrier for this composition is water.
  • US-A-5 885 678 coats an image-receiving layer formed by coating, in water, a composition comprising a hydrophilic polymer, a mordant, and latex.
  • EP 940,427 discloses a method for making a microporous film for an ink jet recording element in which a hydrophobic polymer and a second hydrophilic polymer or copolymer of N-vinylpyrrolidone is dissolved in a certain solvent system, partially dried, and then washed to extract at least 50% by weight of the second polymer.
  • the amount of the hydrophobic polymer to the second hydrophilic polymer is stated as 2:1 - 1:3.
  • This reference also discloses the addition of a mordant to the polymer mixture.
  • the amount of the mordant to be used is up to 3% by weight of the hydrophobic polymer, which corresponds to a maximum amount of about 2-3 % by weight of the total polymer mixture. There is a problem with using only 3% of the mordant as this low a level does not provide adequate water fastness, as will be shown hereafter.
  • an ink jet recording element comprising a support having thereon an image-receptive layer capable of accepting an ink jet image the layer comprising an open-pore membrane of a mixture of water-insoluble polymer, water-absorbent polymer and mordant polymer, the mixture containing at least 25% by weight of the water-absorbent polymer, at least 7% by weight of the mordant, and the balance being the water-insoluble polymer, the mordant polymer containing a quaternized nitrogen moiety, wherein said image-receptive layer is obtainable by dissolving said mixture of polymers in a solvent mixture, the solvent mixture comprising at least one solvent which is a good solvent for said water-insoluble polymer and at least one poor solvent for said water-insoluble polymer, said poor solvent having a higher boiling point than said good solvent, coating the dissolved mixture on said support, and then drying to remove the solvents to obtain the open-pore membrane.
  • a recording element which will provide improved ink uptake speed and when printed upon has an excellent image quality and improved water fastness.
  • Another object of the invention relates to an ink jet printing method comprising the steps of:
  • the water-insoluble polymer In order for the image-receptive layer to be sufficiently porous, the water-insoluble polymer must be coated from a solvent mixture combination such that an open-pore membrane structure will be formed when the solution is coated and dried, in accordance with the known technique of dry phase inversion.
  • the formation of an open-pore membrane is accomplished by using a mixture of a good and poor solvent for the water-insoluble polymer.
  • the poor solvent has a boiling point that is higher than that of the good solvent.
  • the good solvent evaporates faster than the poor solvent, forming the membrane structure of the layer when the polymer phase separates from the solvent mixture.
  • the open-pore structure results when the good solvent and poor solvent are removed by drying.
  • the water-insoluble polymer that can be used in the invention may be, for example, a cellulose ester such as cellulose diacetate, cellulose triacetate, cellulose acetate propionate or cellulose acetate butyrate, cellulose nitrate, polyacrylates such as poly(methyl methacrylate), poly(phenyl methacrylate) and copolymers with acrylic or methacrylic acid, or sulfonates, polyesters, polyurethanes, polysulfones, urea resins, melamine resins, urea-formaldehyde resins, polyacetals, polybutyrals, epoxies and epoxy acrylates, phenoxy resins, polycarbonates, vinyl acetate polymers and copolymers, vinyl chloride-vinyl acetate copolymers, vinyl chloride-vinyl acetate-vinyl-alcohol copolymers, vinyl chloride-vinyl acetate-maleic acid polymers, vinyl chloride
