The present invention discloses a method of making core-shell polymer particles, comprising forming a linking-group-containing polymer by derivatizing a hydroxy-group-containing polymer, comprising hydroxy groups on adjacent carbon atoms with a linking agent, that is a compound comprising both an aldehyde moiety and an amine moiety, wherein one or more acetal moieties are formed in the linking-group-containing polymer, each acetal formed by the reaction of the aldehyde moiety in the linking agent with two hydroxy groups in the linking-group-containing polymer, wherein the amine moiety then becomes a linking group pendent from the linking-group-containing polymer, wherein the linking group is capable of reacting with a precursor group in the precursor polymer. Also disclosed are compositions comprising insoluble core-shell particles made by the method.

Encapsulated mordant particle dispersion and method of preparing

An inkjet printing system contains an inkjet printer loaded with a recording element comprising a support and an ink receiving layer containing: a) fusible polymeric particles; and b) a water soluble block copolymer having ethylene oxide and propylene oxide segments, the copolymer exhibiting a Draves wetting coefficient, for a 0.1 wt % solution in water at 25&#xb0; C., of not more than 360 seconds. An inkjet printing method and an inkjet recording medium are also contemplated.

Fusible inkjet recording media

The present invention is directed to an image-recording medium comprising a paper support and, coated on one side of the support, in order: a lower ink-receiving layer, an upper gloss layer and, coated on the opposite side of the support, an inner layer comprising at least 75% by weight of fine inorganic particles and a binder, and an outer layer substantially consisting of a polymeric material. Another aspect of the present invention relates to an inkjet printing process.

Recording element for aqueous inks

The present invention discloses an ink printing method using an image-recording element, which provides an image having excellent image quality and superior dry time, comprising insoluble cationic core-shell polymeric particles each comprising a core comprising cationic core polymer having at least 10 mole percent of a cationic mordant monomeric unit and a shell comprising hydrophilic shell polymer that is substantially less cationic than the cationic core polymer, wherein the shell is at least 10% by weight of the core.

Image recording element comprising encapsulated mordant particles

An inkjet recording element comprising a support having thereon in order, from top to bottom, an upper fusible, porous layer comprising fusible polymeric particles, which particles comprise a thermoplastic polymer with reactive functional groups, the inkjet recording element further comprising a lower crosslinker-containing layer in which a polyfunctional compound has complementary reactive functional groups capable of crosslinking the reactive functional groups on the thermoplastic polymer under fusing. Optionally, an ink-carrier-liquid receptive layer is present between the fusible, porous layer and the support. Also disclosed is a method of inkjet printing on the element.

Fusible reactive media comprising crosslinker-containing layer

An inkjet recording element comprising a support having thereon in order, from top to bottom, a fusible, porous ink-transporting layer comprising fusible polymeric particles, which particles comprise a thermoplastic polymer with reactive functional groups, the ink-transporting layer further comprising a multifunctional compound having complementary reactive functional groups capable of crosslinking the reactive functional groups on the thermoplastic polymer. The ink-transporting layer is over a fusible dye-trapping layer that preferably comprises a mordant. Optionally, an ink-carrier-liquid receptive layer is present between the dye-trapping layer and the support.

Fusible reactive media comprising mordant
