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.

DETAILED DESCRIPTION The present invention is directed to a method for forming an image and an imaging element for use in said method.
The method comprises an imagewise exposure of an imaging element with a laser wherein the imaging element comprises 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 image-receiving layer adapted to receive ink from said microcapsules over said imaging element and repturing said microcapsules whereby ink from said microcapsules in the exposed areas of said barrier layer diffuses to said superposed receiving layer forming an image corresponding to the laser exposure.
