Definitions

  • the present invention relates 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 and 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-receiving layer, and includes those intended for reflection viewing, which have an opaque support, and those intended for viewing by transmitted light, which have a transparent support.
  • porous recording elements have been developed which provide nearly instantaneous drying as long as they have sufficient thickness and pore volume to effectively contain the liquid ink.
  • a porous recording element can be manufactured by cast coating, in which a particulate-containing coating is applied to a support and is dried in contact with a polished smooth surface.
  • Inkjet prints prepared by printing onto ink jet recording elements, are subject to environmental degradation. They are especially vulnerable to damage resulting from contact with water and atmospheric gases such as ozone. The damage resulting from the post imaging contact with water can take the form of water spots resulting from deglossing of the top coat, dye smearing due to unwanted dye diffusion, and even gross dissolution of the image recording layer. Ozone bleaches inkjet dyes resulting in loss of density. To overcome these deficiencies ink jet prints are often laminated. Lamination is however expensive as it requires a separate roll of material. Alternatively ink jet recording elements having a two-layer construction have been employed.
  • These elements typically have a porous ink-transporting topcoat of thermally fusible particles residing on either a swellable or porous ink-retaining layer. Upon printing the ink passes through the topcoat and into an ink-retaining layer. The topcoat layer is then sealed to afford a water and stain resistant print.
  • Such topcoats containing thermally fusible particles typically either, contain a binder or are thermally sintered to provide a level of mechanical integrity to the layer prior to the imaging and fusing steps.
  • Print protection can also be provided by coating a polymer solution or dispersion on the surface of an inkjet media after image is formed.
  • the aqueous coating solutions are often polymer dispersions capable of film-formation when water is removed.
  • EP 0858905 A1 relates to the preparation of a recording medium comprising a porous outermost layer by coating and drying a particulate thermoplastic resin above its glass transition temperature (Tg), but below its minimum film formation temperature (MFFT).
  • Tg glass transition temperature
  • MFFT minimum film formation temperature
  • the drying temperature has to be controlled very precisely between the Tg and MFFT in order to achieve the desired result. If the drying temperature is below the Tg, then a powdery layer is formed. If the drying temperature is above MFFT, then a complete coalesced film is formed which will not transport ink.
  • EP 1132218 A1 discloses an ink jet element having an image-receiving layer comprising an inorganic filler and coated particles.
  • the inorganic filler is present in an amount of from 50 to 95% by weight.
  • an ink jet recording element comprising a support having thereon a fusible, porous, image-receiving layer comprising non-porous polymeric particles having a core/shell structure comprising a polymeric, hydrophobic core covered with a polymeric, hydrophobic shell, the Tg of the polymeric, hydrophobic core being at least 25° C higher than the Tg of the polymeric, hydrophobic shell, and wherein there is an ink-retaining layer between said support and said image-receiving layer.
  • a porous ink jet recording element is obtained that, when printed with an ink jet ink, has good abrasion and water-resistance, and is flexible after printing and fusing to provide resistance to cracking.
  • the non-porous polymeric particles which are used in the invention, comprise a polymeric core covered with a shell of a water-insoluble polymer.

  • the polymeric core and the polymeric shell are made from a styrenic or an acrylic monomer. Any suitable ethylenically unsaturated monomer or mixture of monomers may be used in making such styrenic or acrylic polymer.
  • styrenic compounds such as styrene, vinyl toluene, p-chlorostyrene, vinylbenzylchloride or vinyl naphthalene
  • acrylic compounds such as methyl acrylate, ethyl acrylate, n-butyl acrylate, n-octyl acrylate, 2-chloroethyl acrylate, phenyl acrylate, methyl- ⁇ -chloroacrylate, methyl methacrylate, ethyl methacrylate, butyl methacrylate; and mixtures thereof.
  • methyl methacrylate or styrene is used.
  • Core-shell particles employed in this invention are in general prepared by a sequential emulsion polymerization technique.
  • the core polymer latex is polymerized first followed by the sequential feeding of the second monomer emulsions to form a core-shell structure.
  • Examples of core-shell particle preparation can be found in "Emulsion Polymerization and Emulsion Polymers", P. A. Lovell and M. S. El-Aasser, John Wiley & Sons, Ltd., 1997.

In yet another preferred embodiment, the particles having a core/shell structure have a polydispersity index of particle size distribution of less than 1.3.
  • a suitable crosslinking monomer may be used in forming the polymeric core in order to modify the non-porous polymeric particle to produce particularly desired properties.
  • Typical crosslinking monomers are aromatic divinyl compounds such as divinylbenzene, divinylnaphthalene or derivatives thereof; diethylene carboxylate esters and amides such as ethylene glycol dimethacrylate, diethylene glycol diacrylate, and other divinyl compounds such as divinyl sulfide or divinyl sulfone compounds. Divinylbenzene and ethylene glycol dimethacrylate are especially preferred. While the crosslinking monomer may be used in any amount, at least 27 mole % is preferred.
