Abstract (en)

A process of forming a single color image comprising: a) imagewise exposing, by means of a laser, a dye-ablative recording element comprising a support having thereon, in order, a hydrophilic dye-receiving layer and a hydrophobic dye-barrier layer, at least one of the dye-receiving layer and the dye-barrier layer having an infrared-absorbing material therein or in a layer therebetween to absorb at a given wavelength of the laser used to expose the element, thereby imagewise heating the dye-barrier layer and causing it to ablate; b) removing the ablated dye-barrier layer material; c) contacting the imagewise-exposed element with an aqueous ink solution; and d) drying the element to obtain a single color image in the ablative recording element.
