Patent ID: 7655286

Claim:
An inkjet recording element comprising a support having in order thereon: (a) a fusible, porous ink-transporting top layer, present in an amount from about 1 g/m 2 to about 50 g/m 2 , comprising (i) fusible polymeric particles, having an average particles size of about 0.2 to about 2 μm, that comprise a thermoplastic polymer having reactive functionalities, wherein the thermoplastic polymer is a polyacrylate polymer or copolymer having one or more monomeric units derived from an alkyl acrylate or alkyl methacrylate monomer, wherein the alkyl group has 1 to 10 carbon atoms, wherein the fusible polymeric particles have a monodispersity less than 1.3, (ii) in addition to the fusible polymeric particles, a multifunctional compound having complementary reactive functionalities capable of reacting with the reactive functionalities on the polyacrylate polymer or copolymer to form crosslinking when fused, and (iii) in addition to the fusible polymeric particles and the multifunctional compound, optionally binder; wherein the thermoplastic polymer in the fusible polymeric particles in the ink-transporting top layer comprise monomeric units having reactive functionalities selected from the group consisting of oxazoline, acid, acid anhydride, acetoacetoxy, primary or secondary amine, hydroxyl, phenol, thiol and isocyanate functionalities, and wherein the multifunctional compound has complementary reactive functionalities selected from the group consisting of oxazoline, epoxy, acid, acid anhydride, acetoacetoxy, primary or secondary amine, hydroxyl, phenol, thiol and isocyanate functionalities, such that the thermoplastic polymer comprising the fusible polymeric particles are crosslinked by the reaction of the reactive functionalities with the complementary reactive functionalities, after printing on the inkjet recording element and subsequent fusing; (b) a fusible dye-trapping layer comprising fusible polymeric particles, a dye mordant, and an optional hydrophilic binder; and (c) optionally an ink-carrier-liquid receptive layer.
