ABSTRACT:
Disclosed is a process which comprises incorporating into an electrostatic imaging apparatus a recording sheet comprising a support on one surface of which are situated microcapsules which comprise a shell and a core containing a color former and an oil, said microcapsules being strengthened with polymer capable of degrading upon exposure to actinic radiation; generating an electrostatic latent image on an imaging member in the apparatus; developing the latent image with a developer; transferring the developed image to the recording sheet; and, subsequent to transfer and fusing, exposing the recording sheet to actinic radiation at a wavelength at which the polymer will degrade, thereby rendering the microcapsules subject to rupture upon application of pressure. The process enables the use of carbonless papers in electrostatic imaging apparatuses while preventing premature rupture of the color former microcapsules by pressure exerted within the apparatus and reduces or eliminates contamination of the apparatus as a result of ruptured color former microcapsules.
