ABSTRACT:
A process for using laser dye-ablative recording element having high blue and ultraviolet contrast comprising a support having thereon a dye layer comprising a blue-absorbing dye, an ultraviolet-absorbing dye and an image dye dispersed in a polymeric binder, the dye layer having an infrared-absorbing material associated therewith to absorb at a given wavelength of the laser used to expose the element, the image dye being substantially transparent in the infrared region of the electromagnetic spectrum and absorbing in the region of from about 450 to about 700 nm and not having substantial absorption at the wavelength of the laser used to expose the element, the element having:
