Abstract: The present invention relates to a coating or composition comprising, and a method of making, multifunctional polymer particles comprising at least two reactive functionalities in the same particle, for example, an epoxy-functional or hydroxy-functional group in combination with an acid-functional group. Non-porous or porous coating compositions made from such a dispersion can be used to protect various substrates, including imaging layers, so that the coated product resists fingerprints, common stains, and spills.

Abstract: 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.

Abstract: An inkjet recording element comprises a support having thereon in order, from top to bottom, a fusible, porous layer comprising a mixture of fusible reactive polymer particles that comprise a thermoplastic polymer, with at least two reactive functional groups on two different particles in the mixture are capable of crosslinking with each other in the different particles. 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.
