Abstract
An ink jet printing method, including 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 including a support having thereon in order:I) a porous base layer including particles having a primary particle size of from about 7 to about 40 nm in diameter which may be aggregated up to about 300 nm and which are dispersed in a binder; andII) a porous image-receiving layer including:(a) particles having a primary particle size of from about 7 to about 40 nm in diameter which may be aggregated up to about 300 nm; and(b) water insoluble, cationic, polymeric particles comprising at least about 20 mole percent of a cationic mordant moiety;the thickness of layer I) being between about 35 and about 50 &mgr;m and the thickness of layer II) being between about 2 and about 6 &mgr;m;C) loading the printer with an ink jet ink composition; andD) printing on the image-receiving layer using the ink jet ink composition in response to the digital data signals.
