Abstract:
1. An inkjet recording element comprising a support having thereon a crosslinkable, fusible, porous top layer comprising (i) fusible, polymeric particles that comprise a thermoplastic polymer having reactive functional groups, 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, and 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 during fusing after printing, and (iii) in addition to the fusible polymeric particles and the multifunctional compound, optionally binder; wherein the thermoplastic polymer in the fusible polymeric particles 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.
