Abstract:
A process for making an ink jet image display comprising:A) providing an inkjet recording element comprising a substantially transparent support having thereon, in the order recited, a base layer comprising a hydrophilic or porous material and a porous, ink-receptive top layer capable of accepting an ink jet image comprising a polymeric adhesive binder and thermally-activated adhesive polymeric particles, the particle-to-binder ratio being between about 95:5 and 70:30, and wherein both said binder and the polymer used to make said polymeric particles have: a) a tensile strength at break of greater than about 1 MPa; b) an elongation at break of greater than about 10%; c) a tensile modulus of greater than about 1 MPa; and d) a Tg of less than about 50Â° C.; â€ƒand said polymeric particles also having a particle size of less than about 10 &mgr;m, a Tm or softening point of greater than about 50Â° C., and said polymer used to make said polymeric particles comprises a polycaprolactone; B) printing an ink jet image on said recording element; C) bringing said top layer of said recording element in contact with another substrate to form a composite assemblage; and D) subjecting said composite assemblage to heat and pressure to adhere said recording element to said substrate to form said ink jet image display.
