This invention relates to an ink jet ink composition comprising an aqueous medium and at least two different polymers, a first polymer and a second polymer, having a weight average acid number of 70 to 200. In one embodiment the ink is substantially colorless.

Ink jet ink composition

An ink jet recording element having a support having thereon an image-receiving layer of a polymeric network formed by a chemical reaction between a wet-strength polymer, amino-functionalized inorganic particles and a hydrophilic polymer other than a wet-strength polymer.

Ink jet recording element

An ink jet recording element having a support having thereon a porous image-receiving layer with at least 30% by weight of particles and at least 30% by weight of a binder, the particles being a mixture of a) silica gel particles having an average particle size of greater than about 9 &mgr;m in diameter; and b) silica gel particles having an average particle size of between 1 and about 8 &mgr;m in diameter; wherein the ratio of the a) silica gel particles to the b) silica gel particles is from about 0.5 to about 5.
