Abstract (en)
[origin: EP0183528A2] Full colour photographic images are produced by exposure of a radiation-sensitive element comprising at least three silver halide emulsion layers. At least two silver halide emulsion layers are sensitized to infrared radiation. Selectively absorptive filter layers and/or differential sensitivities between emulsion layers are used to prevent exposure of other layers to radiation used to expose a single layer.
