Abstract:
An inkjet ink jet printing method, comprising the steps of:A) providing an ink jet printer that is responsive to digital data signals; B) loading said printer with ink jet recording elements comprising a support having thereon, in the order recited, at least one base layer comprising a hydrophilic or porous material and a porous top layer capable of either retaining or transporting an ink image, said porous top layer comprising a polymeric binder and thermally-compliant core-shell particles, the particle-to-binder ratio being between about 95:5 and 50:50, and wherein each said thermally-compliant core-shell particle has: i) a shell of inorganic colloidal particles, and ii) a core of a thermoplastic polymer, â€ƒsaid particles having a particle size between about 0.5 &mgr;m and about 10 &mgr;m, said polymeric core having a softening point of greater than about 50Â° C., and the weight ratio of the shell of said inorganic colloidal particles to said thermoplastic core being from about 1:5 to about 1:99; C) loading said printer with an ink jet ink composition; and D) printing on said ink jet recording element using said ink jet ink in response to said digital data signals.
