Abstract
A process of forming a single color, ablation image having improved abrasion resistance having the following steps: a) imagewise-heating, by a laser, an ablative recording element having a support having thereon an image layer having a colorant dispersed in a polymeric binder, which causes the image layer to ablate imagewise, the image layer having a near infrared-absorbing material associated therewith to absorb at a given wavelength of the laser used to expose the element, the image dye or pigment absorbing in the region of from about 300 to about 700 nm; and b) laminating a coating having polymeric particles dispersed in a binder to the surface of the ablative image under heat and pressure so that the particles will fuse into a continuous overcoat layer.
