Laser addressable thermographic devices (LASER ADDRESSABLE THERMOGRAPHIC ELEMENTS)

摘要

The present invention relates to non-photosensitive organic silver salts; A reducing agent for silver ions; Binder; toner; And a substrate having at least one surface coated with a thermographic imaging system having at least one layer containing a dye that absorbs radiation in the wavelength range of about 750 to about 110 nm. RTI ID = 0.0 . Preferably a layer adjacent to one layer containing a binder and a non-photosensitive organo silver salt containing a further dye that absorbs radiation in the wavelength range of about 750 to 1100 nm, and the like. When the thermographic image element is exposed to radiation of 750 to 1100 nm of 0.10 to 2.0 J / cm 2 for 0.20 to 200 microseconds, an image density of about 1.0 or more is formed. When a thermographic imaging element is imaged in both adjacent layers or only in a layer containing a binder and a dye, the radiation is converted into a radiation-absorptive dye in a layer containing the radiation-absorbing dye and the binder, A photosensitive organic silver salt or the like.
