Abstract (en)
[origin: EP0796742A2] An infrared laser heat sensitive recording material is provided which includes a support and a heat sensitive layer provided thereon. The heat sensitive layer includes an organic silver salt, a developer for the organic silver salt, a water soluble binder, and a tricarbocyanine dye having at least two acidic groups whose maximum absorption wave length is at least 50 nm longer than a maximum absorption wave length of an aqueous solution of the tricarbocyanine dye and is in a range of 650 to 1300 nm. The present invention increases infrared laser light absorption efficiency, reduces degree of coloration of background, and enables recording of images with good quality.
