Laser-imageable element having a stablising infrared-absorbing dye

摘要

A laser-exposed thermal recording element comprising a support having thereon a dye layer comprising a dye dispersed in a polymeric binder, the dye comprising a laser light-absorbing dye absorbing at the wavelength of a laser used to expose the element, wherein the dye layer also contains a stabilizing IR-absorbing dye with an absorption wavelength maximum approximately equal to or longer than that of the laser light-absorbing dye.
