  • Patent number: 6447111
    Abstract: An ink jet printing method having the steps of: I) providing an ink jet printer that is responsive to digital data signals; II) loading the printer with a porous ink jet recording element having a support having thereon an image-receiving layer having: (a) inorganic particles having a primary particle size of from about 7 to about 40 nm in diameter which may be aggregated up to about 500 nm; (b) colloidal particles having a mean particle size of from about 20 to about 500 nm; (c) water-insoluble, cationic, polymeric particles having at least about 20 mole percent of a cationic mordant moiety; and (d) inorganic particles encapsulated with an organic polymer having a Tg of less than about 100° C.; III) loading the printer with an ink jet ink composition; and IV) printing on the image-receiving layer using the ink jet ink composition in response to the digital data signals.
