摘要:
Dry or liquid developers capable of forming high resolution electrostatographic images are made from finely divided toner particles comprising a fusible branched chain, polyester resin which contains 2,3-dihydro,1,3-dioxo-2-yl-1H-isoindole-ar(-yl or -diyl) groups derived, for example, from a 2,3-dihydro-1,3-dioxo-1H-isoindole-5-carboxylic acid. The toner compositions are brittle and can be ground to very small particle size for high resolution image development; they have good cohesivity and resist toner offset; they are fusible at low temperatures; and, in preferred embodiments, are capable of forming transparent color images.
摘要:
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.
摘要:
A process for laminating an ink jet print having the steps of: a) providing an ink jet print having a support having thereon an ink jet image; b) contacting the imaged surface of the ink jet print with a transfer laminating element to form a composite, the transfer laminating element having a flexible, polymeric support having thereon a protection layer of a water-dispersible, hydrophobic polyester resin having the following general formula: In-P-Am wherein I is an ionic group; n is an integer from 1-3; P is a polyester backbone; A is an aliphatic group having a straight or branched chain fatty acid or triglyceride thereof halving from about 6 to about 24 carbon atoms; and m is an integer from 3-8; c) applying heat and pressure to the composite to transfer the layer on top of the ink jet image; d) allowing the composite to cool; and e) peeling the flexible, polymeric support of the transfer laminating element from the composite to form the laminated ink jet print.
