Definitions

  • the invention broadly relates to image receiving elements and methods of manufacturing and using such elements. More specifically, the invention relates to inkjet receptors, also known as inkjet recording sheets, and methods of manufacturing and using such elements.
  • Ink jet printing is a printing technique in which images (e . g ., graphs, pictures, symbols, text, etc.) are produced by the ejection of uniformly shaped droplets of ink onto the receptor surface of a recording sheet.
  • images e . g ., graphs, pictures, symbols, text, etc.
  • This printing technique is widely used in the personal and small office markets. Other applications include low end proofing, and medical referral markets.
  • the maximum image resolution and throughput of an ink jet printer are primarily determined by the size of the jetted drop and the rate of drop ejection. Several factors limit inkjet printers from attaining the maximum image resolution capable of being achieved by the printer. One of these limiting factors is the nature of the recording sheet receiving the jetted drops.
  • Ink receptor surfaces can be divided into two basic types: continuous phase systems and discontinuous phase systems.
  • Continuous phase systems generally function by swelling to absorb water or ink deposited onto the receptor surface, with the rate of absorption determined by the chemical nature of the polymer used in the system.
  • Typical polymers used in continuous phase systems include gelatins, polyvinyl alcohol and cellulose.
  • Exemplary continuous phase systems are discussed in United States Patents Nos. 3,889,270, 4,503,111, and 5,141,599.
  • Discontinuous phase systems function by providing pores within the receptor surface capable of absorbing ink by capillary forces. Discontinuous phase systems are generally preferred over continuous phase systems as they absorb ink considerably faster than continuous phase systems.
  • a first type of a discontinuous phase system utilizes micron sized porous pigment particles in the recording layer for purposes of absorbing ink jetted onto the recording layer into the particles through a multitude of tiny interconnected pores in each particle.
  • Ink recording sheets having a porous, discontinuous phase system recording layer are disclosed in United States Patent Nos. 5,165,973; 5,270,103; 5,397,619; and 5,478,631, and International Published Application WO 97 01448.
  • nonporous discontinuous phase system utilizes nonporous pigment particles held together by a polymeric binder in such a manner that interstitial voids are created between the pigment particles capable of absorbing ink jetted onto the receptor surface.
  • Ink jet recording sheets with a recording layer of the porous discontinuous phase system type generally provide good ink absorptivity and superior ink capacity, in exchange for some loss in the glossy appearance of the recording sheet.
  • ink jet recording sheets with a recording layer of the nonporous discontinuous phase system type provide superior ink absorptivity and a glossy appearance in exchange for a limited ink capacity due to practical limitations upon the thickness of the coating.
  • Discontinuous phase system receptor surfaces often incorporate a mordant or dye fixing agent for purposes of binding the dye molecules adsorbed within the pores of the receptor surface.
  • mordants include neutral silane coupling agents, such as disclosed in JP 8164667 (polyalkylene oxide silane), JP 3218887 (silicon compounds), JP 62178384 (silane coupling agents) and JP 60224580 (silane coupling agents with chloro, amino, aminoethyl or vinyl functionality); and monomers, oligomers and polymers of primary, secondary and tertiary amines and quaternary ammonium salts, such as disclosed in United States Patents Nos. 5,302,437 and 5,750,200.
  • WO-A-99 06219 discloses an ink jet recording sheet wherein the surface of the sheet is coated with an ink receptive layer of an aqueous sizing medium containing a divalent metal salt such as calcium chloride and magnesium chloride.
  • the sizing medium may include other conventional additives such as carrier agents, fillers, optical brightening agents, defoamers and biocides.
  • WO-A-95 28285 discloses an ink jet recording sheet wherein the surface of the sheet is coated with an ink receptive layer containing a trivalent salt or complex of a Group IIb metal, such as lanthanum.
  • the salts can also be used in the form of their double salts containing Ca, Mg, Ba, Na, K or the like.
  • the ink receptive layer preferably includes a film forming hydrophilic polymeric material.
  • GB-A-2 147 003 discloses an ink jet recording sheet wherein the surface of the sheet is coated with an ink receptive layer containing a binder, a pigment, a watersoluble salt with a valency of 2 to 4, and a cationic organic material.
  • EP-A-0 736 392 discloses an ink jet recording sheet wherein the surface of the sheet is coated with an ink receptive layer containing an alumina hydrate having a boehmite structure and a binder.
  • the ink receptive layer may also include metal oxides, polyvalent metal salts, and cationic organic substances.
  • the dry ink receptive layer may be treated with a metal alkoxide or other material capable of crosslinking a hydroxyl group to the ink receptive layer.
  • EP-A-0 199 874 discloses an ink jet recording sheet wherein the surface of the sheet is coated with an ink receptive layer containing polyethylene oxide and a white filler.
  • the ink receptive layer preferably also includes a cationic resin and/or polyvalent metal salt.
  • the ink receptive layer may also include a resin.
  • neutral silane coupling agents, cationic monomeric, oligomeric and polymeric amines, and quaternary ammonium salts are generally effective for providing an acceptable rate of adsorption of dye to a receptor surface
  • a substantial need continues to exist for an ink receptor surface capable of providing a superior dye adsorption rate while maintaining dye adsorption capacity, bonding strength of the dye to the surface of the receptor layer, ink absorption rate and ink absorption capacity.

  • Pigment particles having an average particle size of less than about 500 nm are capable of producing a recording layer 40 having the desired appearance and performance. Pigment particles having an average particle size of between about 10 - 500 nm are generally preferred, with particles having an average particle size of between about 50 - 300 nm desired and particles having an average particle size of between about 50 - 100 nm favored.

  • the pigment particles are held together by a binder.
  • the binder is provided in an amount sufficient to hold the pigment particles together and provide an acceptable appearance. It is generally desired to limit the amount of binder so as to provide pores (i.e., interconnected interstitial voids) within the recording layer 40 for purposes of enhancing performance.
