Definitions
- This invention relates to an ink jet recording element and a printing method using the element. More particularly, this invention relates to an ink jet recording element containing a multiplicity of particles.
- 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.

- a major challenge in the design of a porous image-recording layer is to be able to obtain good quality, crack-free coatings with as little non-particulate matter as possible. If too much non-particulate matter is present, the image-recording layer will not be porous and will exhibit poor ink dry times.
