Abstract

Disclosed is a process for simultaneously transferring and fixing photoelectrophoretic images using heat and pressure. This system relies on a temperature control and a polymer surface which will accomodate oil upon heating. In one embodiment the process steps involve: (1) simultaneously transferring and fixing a photoelectrophoretic image onto a polymer-coated paper by passing the pigment oil latent image in contact with the polymer-coated paper through a nip of heated rollers; (2) inverting the above print and contacting it with a release sheet with the fixed image. This sandwich can then be passed through the nip of the heated rollers at fixing temperatures. In an alternative embodiment, if this step can be accomplished without degrading the image, transfer and fix, then duplexing is possible, that is obtaining images on both sides of the same sheet if the polymer was present on both sides of such sheet.

Disclosed is a process for simultaneously transferring and
fixing photoelectrophoretic images using heat and pressure.
This system relies on a temperature control and a polymer
surface which will accomodate oil upon heating. In one
embodiment the process steps involve: (1) simultaneously
transferring and fixing a photoelectrophoretic image onto a
polymer-coated paper by passing the pigment oil latent image
in contact with the polymer-coated paper through a nip of
heated rollers; (2) inverting the above print and contacting
it with a release sheet with the fixed image. This sandwich
can then be passed through the nip of the heated rollers at
fixing temperatures. In an alternative embodiment, if this
step can be accomplished without degrading the image, transfer
and fix, then duplexing is possible, that is obtaining images
on both sides of the same sheet if the polymer was present on
both sides of such sheet.
