Definitions

  • This invention relates to an ink jet recording element. More particularly, this invention relates to an ink jet recording element containing porous polymeric particles 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, 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.
