Abstract
An ink jet recording medium is disclosed. The recording medium comprises a support and a porous ink absorbing layer comprising inorganic particles and hydrophilic binder which is hardened employing inorganic hardener and organic hardener. The ink jet recording medium exhibits high ink absorbability and desired water resistance without degrading layer brittleness through sufficiently hardening the layer employing an appropriate amount of hardeners.
Claims22
An ink jet recording medium comprising a support having thereon at least one porous ink absorbing layer comprising inorganic particles and a hydrophilic binder which is hardened by employing an inorganic hardener and an organic hardener,
- wherein the weight ratio of the inorganic particles to the hydrophilic binder is 3:1 to 10:1.
A method of preparing an ink jet recording medium, comprising the steps of:
- coating onto a support a composition for forming an ink receiving layer, wherein the composition comprises inorganic particles and a hydrophilic binder;
- drying the coated composition;
- and then supplying a hardener to the coated composition.
An image forming method, comprising ejecting water soluble ink onto a recording medium which comprises a support having thereon a porous ink absorbing layer comprising inorganic particles and a hydrophilic binder which is hardened employing an inorganic hardener and an organic hardener.
