ABSTRACT:
A method for forming an image which comprises imagewise exposing an imaging element with a laser, said imaging element comprising a support carrying on a first surface, in sequence, a layer of microcapsules containing an ink, and a laser-absorptive, ink barrier layer; superposing an imaging-receiving layer adapted to receive ink from said microcapsules over said imaging element and rupturing said microcapsules; whereby ink from said microcapsules in the exposed areas of the imaging element diffuses to said superposed receiving layer forming an image corresponding to the laser exposure.
