Abstract
A coating fluid for application to a support to prepare an ink jet recording medium comprises an aqueous dispersion of a synthetic polymer hydrogel and gelatin, the amount of the synthetic polymer hydrogel being from 5 to 50% by weight of the combined weight of synthetic polymer and gelatin. Preferably the coating fluid also contains a mordant, an aliphatic alcohol to assist dispersion of the hydrogel polymer and a particulate material to impart a porous structure to the coating. The invention also provides an inkjet recording medium comprising a support on which is an ink-receiving layer comprising the gelatin and a synthetic polymer hydrogel. The amount of the latter may be from 0.3 to 5 g/square meter.
