US Classification:

347105, 347106, 428195

Abstract:

An ink jet printing method comprising the steps of: a) providing an ink jet printer that is responsive to digital data signals; b) loading the printer with an ink jet recording element comprising a substrate having thereon an image-receiving layer comprising an inorganic, anionic pigment, an organic, anionic binder and an organic, cationic mordant, and a porous overcoat layer located over the image-receiving layer, the porous overcoat layer comprising an inorganic pigment and an organic, anionic, binder, wherein the refractive index of the inorganic pigment in the overcoat layer is at least 0. 05 refractive index units less than the refractive index of the inorganic, anionic pigment in the image-receiving layer; c) loading the printer with an ink jet ink composition; and d) printing on the recording element using the ink jet ink in response to the digital data signals.
