摘要:
There are disclosed an ink-receiving composite polymer material wherein a nonvolatile organic compound is caused to penetrate into and diffuse through an ink-receiving polymer forming, from any one surface side thereof, and a recording medium for ink-jet recording wherein a nonvolatile organic compound is caused to penetrate into and diffuse through an ink-receiving layer, from the surface thereof.
摘要:
A recording medium comprises an ink receiving layer provided on a substrate, wherein said ink receiving layer contains a cationically modified product of polyvinyl alcohol and a water soluble polymer having no active hydrogen.
摘要:
A recording medium comprising a substrate and a non-porous ink receiving layer is provided. The ink receiving layer contains a water-insoluble polymer containing a cationic resin. The recording medium may be employed for recording by attaching droplets of a recording liquid thereon.
摘要:
A recording medium for recording with aqueous ink without direct contact of recording means therewith comprises an under layer and an upper layer provided thereon. The upper layer is formed of substantially water-resistant resin and is sufficiently thin to provide immediate water and air permeability and the under layer is more hydrophilic than the upper layer. There is also provided a recording process employing aqueous ink droplets and a recording medium as mentioned above.
